Note: The ServSwitch CX Uno IP unit can be powered on during this procedure,

however, the switch boxes should be switched off. The conﬁguration steps below

are for one type of power switch. Other power switches may require different

conﬁguration. Please refer to your power switch documentation.

The options port of the ServSwitch CX Uno

IP can be used to connect to one or more

optional power control units. This allows you to

control the mains power being supplied to the

connected computer(s) so that an authorized

user can, if necessary, perform a complete

remote cold reboot on a failed system.

• Addressing computers in a cascade

724-746-5500

1 Mount up to four switch boxes in positions where they are close to the

computer systems that they will control and not too distant from the

ServSwitch CX Uno IP unit (preferably within 2.5 metres).

2 Use a serial cable with an RJ9 and a 9-pin D-type connector (see Appendix

7 for speciﬁcation). Attach the RJ9 plug to the socket marked IN on the

ﬁrst switch box. Attach the other end to the socket marked OPTIONS on the

ServSwitch CX Uno IP.

The control connector of the ﬁrst power switch

is attached, via serial cable, to the rear panel of

the ServSwitch CX Uno IP. Any additional power switches are then attached via

a ‘daisy-chain’ arrangement to the ﬁrst power switch. Each power switch box

is then given a unique address and access to each power port (8 ports on each

power switch box) is gained using a combination of the switch box address and

the port number.

and the power switch box(es) are then connected to a mains power supply.

5 Attach IEC to IEC power leads between

each port and the power input socket of

each computer system that requires power

switching. Carefully note to which power

IMPORTANT: Power switching devices have a maximum current rating. It is

essential to ensure that the total current drawn by the equipment connected

to the power switching device does not exceed the current rating of the power

switching device. You must also ensure that the current drawn from any mains

socket does not exceed the current rating of the mains socket.

ports, on which boxes, each computer system is connected. If computer

systems have multiple power inputs, then each input must be connected via

separate ports, which can be on the same, or different boxes.

Setting up, conﬁguring and using power switching requires three main steps:

• Connect and address the switch boxes



6 Connect each box to a suitable mains power input.

• Conﬁgure the power strings

Now proceed to the conﬁguration stage covered in the Power switching

conﬁguration section within the Conﬁguration chapter.

• Operate power switching via the VNC toolbar or the local Functions menu.

Cascading multiple units

The ServSwitch CX Uno IP units

support up to eight or sixteen

directly connected computer

systems, however, this is by

no means the limit. Instead of

connecting computers to every

output port, you can instead link

ServSwitch CX Uno units (not IP

variants). Thus, each output of

the original ServSwitch CX Uno

IP unit can link through to many

more computers connected to

the secondary ServSwitch CX Uno

units.

The cascade tree

724-746-5500

The diagram shows how an ServSwitch CX Uno IP unit and multiple

ServSwitch CX Uno units can be cascaded to two levels. Computer

systems can be connected at any level. The local or global users can

Addressing computers in a cascade

Computer systems connected within a cascade arrangement are addressed using

up to four digits, two for each cascade level. The pairs of digits specify which of

the COMPUTER CONNECTIONS ports on each of the ServSwitch CX Uno units must

be enabled to reach a speciﬁc computer. In the diagram given here, a portion

of the previous cascade diagram indicates how the routes to two particular

computers are formed and addressed.

Port 12

at cascade

level 1

Each cascade level requires two digits, hence the computer marked in red

requires a longer address (1203) as it is situated at cascade level 2, compared to

the blue computer at the top level with its two digit port number.

The ﬁrst time that you make a connection between an ServSwitch CX Uno IP

and an ServSwitch CX Uno, the master unit will detect this and ask (via the on

screen menu) if you want to automatically add computers. If you choose ‘Yes’

then the ports on the cascade will be automatically added to the on screen

menu.

Multiple video head connections

Two or more ServSwitch CX Uno IP units can be connected together

so that they operate in a synchronized manner. Synchronized

operation is useful for applications that require multiple video

signals to be switched together. This type of operation is usually

required where each computer is ﬁtted with multiple video cards or

video cards with multiple video heads. Whenever an ServSwitch CX

Uno IP channel is switched, it sends an RS232 command out on its

serial interface (marked OPTIONS on the rear panel). An ServSwitch

CX Uno IP will switch its channel if it receives the same command on

its serial interface. Consequently, by linking the serial interfaces, a

master unit may be made to automatically switch one or more slave

units as shown in the diagram.

either via the local or global user conﬁguration menus.

It should be noted that the synchronization cable deliberately does not have the transmit

pin of the Slave End connector linked to the receive pin of the Master End connector. To

do so would cause the Slave unit to be able to switch the Master unit. This would setup an

endless cyclical switching sequence that would prevent the ServSwitch CX Uno IP devices

from operating correctly. For more details about the serial synchronization cables, see

Conﬁguration

Almost all conﬁguration and operational aspects of the ServSwitch CX Uno IP

units are controlled via on-screen menu displays.

Overall initial conﬁguration

When setting up a new installation, the following stages are recommended:

1 Enable the general ‘Security’ option.

With security disabled (default setting), a local or remote user attached

to the ServSwitch CX Uno IP will have full and unrestricted access to all

computers and all ServSwitch CX Uno IP settings. In larger installations, you

are strongly recommended to enable security and set up individual user

accounts with access privileges.

2 Create an ADMIN (administration) password.

All ServSwitch CX Uno IP units have a ﬁxed user account that cannot be

deleted or renamed, called ADMIN. This user account is the only one that is

able to make important system changes. If you intend to use security, then it

is important to allocate a password to the ADMIN account.

3 Create user accounts and allocate access rights.

Use the ADMIN account to add user proﬁles, passwords and access rights

for each of the system users.

4 Provide names for computers.

When numerous computers are attached, you are strongly advised to

provide names for each, to assist with recognition.

5 Conﬁgure the required ‘Setup Options’ and ‘Global Preferences’

Use the ADMIN account to determine key ServSwitch CX Uno IP settings and

timing characteristics.

Encryption settings

The ServSwitch CX Uno IP offers a great deal of ﬂexibility in its conﬁguration

and this extends equally to its encryption settings that are used to prevent

unauthorized interception of signals. Due to the variety of situations in which

the ServSwitch CX Uno IP might be used and the range of viewer applications

that need to view it, a number of settings are available. The encryption settings

to use depend upon how the potential global users will operate.

Important factors to consider when setting these options might be:

• Do all global user connections and operations require encryption?

• Will some global users be using older VNC viewer versions?

ServSwitch CX Uno IP encryption settings

The ServSwitch CX Uno IP conﬁguration menu offers three encryption settings:

• Always on - This setting will force all viewers to use encryption. Note:

This setting will preclude any VNC viewer versions that do not support

encryption.

• Prefer off - This setting does not enforce encryption unless a viewer

speciﬁcally requests it. If a viewer has its ‘Let server choose’ setting, then an

un-encrypted link will be set up.

• Prefer on - This setting generally enforces encryption unless an earlier

viewer version is unable to support it, in which case the link will be un-

encrypted. If a viewer has its ‘Let server choose’ setting, then the link will be

encrypted.

Viewer encryption settings

The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four

encryption settings:

• Always on - This setting will ensure that the link is encrypted, regardless of

the ServSwitch CX Uno IP encryption setting.

• Let server choose - This setting will follow the conﬁguration of the

ServSwitch CX Uno IP. If the ServSwitch CX Uno IP has ‘Always on’ or ‘Prefer

on’ set, then the link will be encrypted. If the ‘Prefer off’ setting is selected

at the ServSwitch CX Uno IP, then the link will not be encrypted.

• Prefer off - This setting will conﬁgure an un-encrypted link if the ServSwitch

CX Uno IP will allow it, otherwise it will be encrypted.

• Prefer on - If the ServSwitch CX Uno IP allows it, this setting will conﬁgure

an encrypted link, otherwise it will be un-encrypted.

Networking issues

Thanks to its robust security the ServSwitch CX Uno IP offers you great ﬂexibility

in how it integrates into an existing network structure. The ServSwitch CX Uno

IP is designed to reside either on an internal network, behind a ﬁrewall/router or

alternatively with its own direct Internet connection.

Positioning ServSwitch CX Uno IP in the network

Every network setup is different and great care needs to be taken when

introducing a powerful device such as the ServSwitch CX Uno IP into an existing

conﬁguration. A common cause of potential problems can be in clashes with

ﬁrewall conﬁgurations. For this reason the ServSwitch CX Uno IP is designed

to be intelligent, ﬂexible and secure. With the minimum of effort it can

reside either behind the ﬁrewall or alongside with its own separate Internet

connection.

If you need to change the VNC port number

Placing ServSwitch CX Uno IP behind a router or ﬁrewall

A possible point of contention between the ServSwitch CX Uno IP and a ﬁrewall

can occasionally arise over the use of IP ports. Every port through the ﬁrewall

represents a potential point of attack from outside and so it is advisable to

minimize the number of open ports. The ServSwitch CX Uno IP usually uses two

separate port numbers, however, these are easily changeable and can even be

combined into a single port.

If you change the VNC port to anything other than 5900, then each VNC viewer

user will need to specify the port address as well as the IP address. For instance,

if you set the VNC port to ‘11590’ and the IP address is ‘192.168.47.10’ then

VNC viewer users will need to enter:

192.168.47.10::11590

(Note the double colons that separate the IP address and port number).

IMPORTANT: The correct conﬁguration of routers and ﬁrewalls requires

advanced networking skills and intimate knowledge of the particular network.

Black Box cannot provide speciﬁc advice on how to conﬁgure your network

devices and strongly recommend that such tasks are carried out by a qualiﬁed

professional.

The ﬁrewall/router would also need to be informed to transfer all trafﬁc to the

new port number through to the ServSwitch CX Uno IP.

Addressing

When the ServSwitch CX Uno IP is situated within the local network, you will

need to give it an appropriate local IP address, IP network mask and default

gateway. This is achieved most easily using the DHCP server option which

will apply these details automatically. If a DHCP server is not available on the

network, then these details need to be applied manually in accordance with the

network administrator.

Port settings

As standard, the ServSwitch CX Uno IP uses two ports to support its two types

of viewer:

• Port 80 for users making contact with a web browser, and

• Port 5900 for those using the VNC viewer.

The ﬁrewall/router must then be informed to route incoming requests to port

5900 or port 80 (if available) through to the local address being used by the

ServSwitch CX Uno IP.

When these port numbers are used, VNC viewers and web browsers will locate

the ServSwitch CX Uno IP correctly using only its network address. The ﬁrewall/

router must be informed to transfer any trafﬁc requesting these port numbers

through to the ServSwitch CX Uno IP.

When a web server is also on the local network

Port 80 is the standard port used by web (HTTP) servers. If the ServSwitch CX

Uno IP is situated within a local network that also includes a web server or any

other device serving port 80 then, if you want to use the web browser interface

from outside the local network environment, the HTTP port number of the

ServSwitch CX Uno IP may need to be changed.

Remote user with VNC viewer

accesses IP address: 129.7.1.10

and automatically uses port

Internet

5900.

When you change the HTTP port to anything other than 80, then each remote

browser user will need to specify the port address as well as the IP address. For

instance, if you set the HTTP port to ‘8000’ and the IP address is ‘192.168.47.10’

then browser users will need to enter:

ServSwitch CX Uno IP has a

local address and net mask,

i.e.

Firewall/router address:

ꢀꢁꢈ.ꢆ.ꢀ.ꢀ0

http://192.168.47.10:8000

(Note the single colon that separates the IP address and the port number).

The ﬁrewall routes the

request from the VNC viewer

on port 5900 through to the

ServSwitch CX Uno IP at local

address 192.168.0.3

IP address: 192.168.0.3

To discover a DHCP-allocated IP address

Once a DHCP server has allocated an IP address, you will need to know it in

order to access the ServSwitch CX Uno IP via a network connection. To discover

the allocated IP address:

1 In network section of either the local conﬁguration menus or the global

conﬁguration pages, set the ‘Use DHCP’ option to ‘Yes’ and select ‘Save’.

Once the page is saved, the ServSwitch CX Uno IP will contact the DHCP

server and obtain a new address.

2 Re-enter the same ‘Network conﬁguration’ screen where the new IP address

and network mask should be displayed.

DNS addressing

As with any other network device, you can arrange for your ServSwitch CX Uno

IP to be accessible using a name, rather than an IP address. This can be achieved

in two main ways:

• For small networks that do not have a DNS (Domain Name System) server,

edit the ‘hosts’ ﬁles on the appropriate remote systems. Using the hosts

ﬁle, you can manually link the ServSwitch CX Uno IP address to the required

name.

• For larger networks, declare the IP address and required name to the DNS

server of your local network.

The actual steps required to achieve either of these options are beyond the

scope of this document.

Placing ServSwitch CX Uno IP alongside the ﬁrewall

ServSwitch CX Uno IP is built from the ground-up to be secure. It employs a

sophisticated 128bit public/private key system that has been rigorously analysed

and found to be highly secure (a security white paper is available upon request

from Black Box). Therefore, you can position the ServSwitch CX Uno IP alongside

the ﬁrewall and control hosts that are also IP connected within the local

network.

Security can be further improved by using the following suggestions:

• Place the ServSwitch CX Uno IP behind a ﬁrewall and use the port numbers

to route the VNC network trafﬁc to an internal IP address.

• Review the activity log from time to time to check for unauthorized use.

• Lock your server consoles after they have been used.

A security white paper that gives further details is available upon request from

Black Box.

IMPORTANT: If you make the ServSwitch CX Uno IP accessible from the public

Internet, care should be taken to ensure that the maximum security available

is activated. You are strongly advised to enable encryption and use a strong

password. Security may be further improved by restricting client IP addresses,

using a non-standard port number for access.

Ports

In this conﬁguration there should be no constraints on the port numbers

because the ServSwitch CX Uno IP will probably be the only device at that IP

address. Therefore, maintain the HTTP port as 80 and the VNC port as 5900.

Ensuring sufﬁcient security

The security capabilities offered by the ServSwitch CX Uno IP are only truly

effective when they are correctly used. An open or weak password or

unencrypted link can cause security loopholes and opportunities for potential

intruders. For network links in general and direct Internet connections in

particular, you should carefully consider and implement the following:

Addressing

When the ServSwitch CX Uno IP is situated alongside the ﬁrewall, it will require

a public static IP address (i.e. one provided by your Internet service provider).

More addressing information:

Discover DHCP-allocated addresses

DNS addressing

• Ensure that encryption is enabled.

By local conﬁguration menu or global conﬁguration page.

• Ensure that you have selected secure passwords with at least 8 characters

and a mixture of upper and lower case and numeric characters.

By global conﬁguration page.

• Reserve the admin password for administration use only and use a non-

admin user proﬁle for day-to-day access.

• Use the latest Secure VNC viewer (this has more in-built security than is

available with the Java viewer). To download the viewer.

• Use non-standard port numbers.

• Restrict the range of IP addresses that are allowed to access the ServSwitch

CX Uno IP to only those that you will need to use. To restrict IP access.

• Do NOT Force VNC protocol 3.3.

• Ensure that the computer accessing the ServSwitch CX Uno IP is clean of

viruses and spyware and has up-to-date ﬁrewall and anti-virus software

loaded that is appropriately conﬁgured.

• Avoid accessing the ServSwitch CX Uno IP from public computers.

Power switching conﬁguration

Power control sequences

Power switch conﬁguration comprises two main steps:

Note: The settings given below are for one type of power switch - other power

switches may require different settings. Please refer to your power switch

documentation for details about codes required by other power switches.

• Conﬁgure the OPTIONS serial port to the same speed as used by the power

switch box(es), using the conﬁguration menu.

The structure of each power sequence (OFF and ON) is as follows:

• Conﬁgure power ON and OFF strings for each relevant host computer.

For each power port there needs to be a valid ‘Power ON string’ and similarly an

appropriate ‘Power OFF string’. In each case, the strings are a short sequence of

characters that combine a port address and a power on or off value.

Pxy=z\0D

Where:

If a particular computer has more than one power input (and thus requires an

equivalent number of power ports to control them), collections of strings can be

combined to switch all of the required ports together as a group.

x is the switch box number,

y is the power port number,

z is ‘0’ for OFF or ‘1’ for ON, and

\0D represents Enter (or Carriage return).

To conﬁgure the power sequences for each host computer

1 Using VNC viewer or a browser, log on as the ‘admin’ user.

Example 1

2 Click the ‘Conﬁgure’ button in the top right corner.

3 Click the ‘Host conﬁguration’ option.

To switch ON port 5 of switch box 2, the code would be as follows:

• Power sequence:

P25=1\0D

4 Click a host entry to display a Host conﬁguration dialog:

5 If necessary, conﬁgure other parameters (Name, Users, Hot Keys - MORE).

Example 2

To switch OFF port 8 of switch box 3, the code would be as follows:

• Power sequence: P38=0\0D

For details about operating this feature, see Power switching control within

the Operation chapter.

To control two or more ports simultaneously

You can control up to four power ports using a single sequence. This is done

using the same command structure as shown above, plus a delay command,

for each port. Immediately following a port command, insert the characters

‘\*’ before the next port command, and so on up to four ports. For instance, to

switch on ports 1 and 2 in the ﬁrst power switch, the command line would be:

6 Enter the Power control sequences in the Power On and Power Off ﬁelds

cascaded hosts.

The problem can occur for two main reasons, either:

• A cascaded computer (or multiple computers) has been added to an

address such as 0301, however, there is still a registered entry for a directly

connected host at address 03. Thus, the now non-existent host at 03 will be

marked with an orange dot.

• A previously connected cascade has been removed and a computer

connected directly instead. This will cause all of the entries for the removed

cascaded hosts to be marked with orange dots. If they are not to be re-

instated, then the administrator should delete the entries.

If you attempt to select an entry marked with an orange dot (by the menu,

by hotkeys or from the VNC viewer) you will see an error message stating

‘computer not connected’.

When using the viewer window

Using the viewer window

The viewer window gives you the ability to view and control the ServSwitch CX

Uno IP and its host computer(s). Its operation is almost identical regardless of

whether you used the VNC viewer or your Web browser to display it.

What is the best screen resolution to use?

The best resolution for your computer is one that is larger than the screen of the host

computer that you are viewing. This will allow you to see everything without scrolling

around. Alternatively, the VNC viewer can be set to scale the image to ﬁt your screen,

but remember that some pixel dithering effect will be seen when scaling is used.

The menu bar

The viewer window presents a menu bar similar to that shown below. Certain

items within the toolbar are displayed depending upon your access permissions

and/or the ServSwitch CX Uno IP conﬁguration.

How do I navigate around a larger screen?

If the screen that you are viewing has a larger resolution than your viewing window

you will need to scroll around to see all items. The viewer window allows you to

‘bump scroll’ (only in full screen mode). This means that when your mouse cursor

bumps against the edge of the screen, the screen image will scroll across automatically.

Both viewers provide a double mouse cursor to help overcome any delays

caused by slow connections. When you move your mouse you will see two

mouse cursors, a local one that responds immediately to your movements and a

second, slower moving, cursor that represents the current mouse position at the

host.

The Hosts button on the menu bar provides the quickest and most efﬁcient way

to switch between host computers. This is because the button is close at hand,

but also because the screen calibration details for each host are reused when

this method of switching is used. The alternative is to use hotkey combinations

Auto calibrate

Re-synchronize mouse

When you visit a host computer for the very ﬁrst time, your viewer needs to

determine the optimum video and mouse settings for that particular computer.

The button will remind you to click it by ﬂashing red when a new computer

screen is encountered. Performing this step is important because it can help

to decrease unnecessary video information being sent across the link, thus

improving overall performance.

If you ﬁnd that your local mouse pointer and that of the host are not correctly

synchronized, use this feature to re-align their movements. This operation is also

selectable from the Controls menu.

To re-synchronize the mouse

1 Use the Hosts button to select the required computer.

2 Click the

button and then click OK in the subsequent pop-up message.

Once this has been done, providing you use the ‘Hosts’ button to switch

between host computers, the video settings for each machine will be re-used.

Note: If you ﬁnd that this doesn’t work, you may need to perform a mouse

calibration again.

Note: When performing an auto calibration, ensure that the screen image

is static (no moving images) and also try to remove any on-screen displays

generated by KVM switches (such as host names or menus). This is because

they can affect the calibration process and result in a lower overall performance

level. For mouse calibration, ensure that there are no application windows

located around the upper left corner of the screen. This is because as the mouse

calibration takes place, the cursor may change (to match the application as it

skims across the window) and this may confuse the calculation. Also ensure that

the host computer does not have the mouse cursor trails option enabled.

Access mode - shared/private

Up to ﬁve users can be simultaneously logged-on (four global users plus one

local or remote user) and during normal operation, all are able to see the same

view of the currently selected host. If you need to perform a sensitive task

that should not be viewed by other users, you can change the access mode to

Private. This action blanks the viewer window for all other logged on users.

Note: For the courtesy of other users, this mode should be used sparingly. The

admin user has the ability to overrule the private setting.

To auto calibrate the screen and/or mouse

1 Use the Hosts button to select the required computer.

Video Settings

This dialog provides access to all of the key video settings that determine image

quality and link performance.

Using automatic conﬁgurations

• Every setting can be individually subjected to an automatic conﬁguration

(click the appropriate ‘Auto’ button) or can also be manually adjusted.

• Use the ‘Calibrate All’ button to automatically determine the optimum

settings for all items.

Threshold

The threshold is effectively a

noise ﬁlter that differentiates

between valid video signals

and background noise or

interference. This has the

effect of reducing unnecessary

video signals between the

ServSwitch CX Uno IP and the

remote system, thus improving

performance.

Note: Before using the ‘Calibrate All’ option, if possible, remove on-screen

display (OSD) elements generated by the ServSwitch CX Uno IP (such as a

host name label or menu). These OSD elements use different video rates

to those of the host system(s) and can affect the setting of the automatic

threshold value. ServSwitch CX Uno IP uses an improved calculation

procedure to ﬁlter out the effect of these elements. However, best results

are obtained when the screen contains only host system information.

Note: To maximize performance, the threshold level is automatically

increased by 50% when a slow link is detected.

Phase

The phase setting adjusts the

alignment of the host video

output and the remote system

video display to achieve the

sharpest image.

Note: When the ServSwitch CX Uno IP is used with one or more other

switches, the threshold needs to be higher than 32 due to the signiﬁcant

amounts of ‘noise’ that these switches introduce. The ServSwitch CX Uno IP

conﬁguration should detect such noise and adjust the threshold accordingly.

Horizontal Position

Determines the horizontal

position of the host screen

image within the viewer

window.

Setting the Threshold manually

Occasionally it can be useful to manually adjust the Threshold setting, in order to

achieve a setting that best suits your particular requirements.

Brightness & Contrast

blue constituents of the

brightness and contrast

can be set individually.

When enabled, the unit will begin capturing the

next frame of video output from the host computer

before it has fully completed processing the current

frame. In most cases this produces better video

performance, however, when moving large objects

around the screen (such as an application window),

the video image seen at the remote system may

exhibit temporary artifacts as the large image

moves.

If you need to enter a port number

Viewer encryption settings

Usually, when you make a network connection to the ServSwitch CX Uno IP

(either using the VNC viewer or a Web browser) you simply enter the IP address,

i.e. 192.168.0.3. However, if a special conﬁguration is necessary, then you may

be asked to specify a port number as well as the IP address.

The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four

encryption options. The resulting actions of certain options depend upon how

the ServSwitch CX Uno IP to which you are connecting is conﬁgured:

• Always on - This setting will ensure that the link is encrypted, regardless of

the ServSwitch CX Uno IP encryption setting.

• Let server choose - This setting will follow the conﬁguration of the

ServSwitch CX Uno IP. If the ServSwitch CX Uno IP has a preference to

encrypt the link, then it will be so, otherwise the link will not be encrypted.

To enter a port number in a Web browser

1 Enter the required IP address in the usual Address box,

i.e. http://192.168.0.3

• Prefer off - This setting will conﬁgure an un-encrypted link if the ServSwitch

3 Continue with the standard Web browser instructions.

Whenever encryption does take place, the viewer will ﬁrst need to create the

necessary secure key before the connection process can continue.

To enter a port number in VNC viewer

Troubleshooting

• Appendix 8 - Hotkey sequence codes

• Appendix 9 - Supported video modes

• Safety information

Global network users are unable to contact the ServSwitch CX Uno IP

• Check that the correct address is being used by the remote users.

• Check the network settings. Check that the users network address has not

been excluded in the IP access control section.

• End user licence agreement

• Certiﬁcation notice for equipment used in Canada

• Normas Oﬁciales Mexicanas (NOM) electrical safety statement

• If the ServSwitch CX Uno IP is situated behind a ﬁrewall, check that the

relevant ports are being allowed through the ﬁrewall and are being

correctly routed.

• Check the front panel indicators, the LNK indicator should be on. If the

network link is a 100Mbps connection, the 100 indicator should also be on.

The remote cursor is not correctly responding to my mouse movements

• Recalibrate the mouse. When doing so, ensure that the host system does

not have mouse cursor trails enabled and that the top left corner of the

screen is clear of application windows.

When logging on using VNC viewer, I cannot enter a username

• Either, the VNC viewer is an old version (download a new one) or only the

admin user has been conﬁgured on the ServSwitch CX Uno IP.

Mouse Switching

OSD Dwell Time

Settings: Enabled, Disabled

Settings: 1, 2, 3, 5, 10 Seconds

The computer channel can be switched using a three button mouse or

IntelliMouse. Pressing the central button or wheel button together with the left

hand mouse button will cause the ServSwitch CX Uno IP to switch to the next

available computer.

After a successful computer channel change the ServSwitch CX Uno IP will

display a conﬁrmation message for a few seconds. The length of time that this

conﬁrmation message dwells on the screen may be changed.

User Timeout

Settings: 1, 2, 5, 10, 30 Seconds, 1, 5, 10 Minutes

When mouse switching is enabled, you can still use the middle button on its

own to control applications. Only when its pressed with the left or right button

is it interpreted by mouse switching, otherwise it is passed on to the host

application. The rotation action of an IntelliMouse wheel is not affected and is

always available to the computer application.

When no keyboard or mouse data has been received from an active user port

for the user timeout period, the ServSwitch CX Uno IP will relinquish the control

of that user port in order to allow other users to access the host computer. The

new port then becomes the active port until it too times out. To avoid confusion

between users it is desirable to set the timeout period to be sufﬁciently long so

that user’s work is not needlessly interrupted by other users and sufﬁciently short

to ensure good overall system efﬁciency.

Screen Saver

Settings: Disabled; 2, 5, 10,15 or 20 Minutes

The ServSwitch CX Uno IP can be set to blank the screen after no keyboard or

mouse activity has been detected for a selected timeout period. If preferred, the

user can blank the screen manually by selecting channel ‘0’ using the keyboard

hotkeys or by pressing ESC from the login screen.

Security

Auto Logout

Settings: Disabled, Enabled

With security disabled there is no requirement for users to log-in to the system.

All users have full access to all the connected computers and full administration

rights. With security enabled, users are required to log-in to the ServSwitch

CX Uno IP. Each user is allocated access rights to computers by the system

administrator and they are only able to see the computers that they have access

to on their on-screen menu.

The ServSwitch CX Uno IP enables you to restrict access to your computers

on a login basis. If a user forgets to logout when they have ﬁnished accessing

the ServSwitch CX Uno IP then the user console may unintentionally be left

with full access to all the computers. The ServSwitch CX Uno IP can be set to

automatically logout unattended user consoles when the screen saver kicks in.

This reduces the risk of security problems by preventing user consoles remaining

in a permanent “logged-in” state when there is no keyboard or mouse activity.

The automatic logout feature is only enabled when the screen saver feature is

active (i.e. not disabled).

Hotkeys

Settings: Ctrl+Alt, Ctrl+Shift, Alt+Shift, Alt Gr, Left+Right Alt, Left Ctrl+Alt,

Right Ctrl+Alt

The keyboard hotkeys are special combinations of keys that, when used together

with certain keyboard “command keys”, perform special ServSwitch CX Uno

IP functions. For example, pressing the hotkeys together with the “M” key

will cause the on-screen menu to be displayed on your monitor. Other hotkey

combinations allow you to query which computer you are connected to and

to move the on-screen menu around the screen. You can also use the hotkeys

together with the port number to select a particular connected computer.

Net Mask

Also often called the ‘subnet-mask’, this value is used alongside the IP address

to help deﬁne a smaller collection (or subnet) of devices on a network. In this

way a distinction is made between locally connected devices and ones that are

reachable elsewhere, such as on the wider Internet. This process helps to reduce

overall trafﬁc on the network and hence speed up connections in general. See

This is the address of the device that links the local network (to which the

Usually this is a network switch or router and it will be used whenever a device

to be contacted lies outside the local network.

VNC Port

MAC Address

This is the logical link through which communications with a remote VNC viewer

will be channelled (see What is a port?). The default setting is 5900 which is

a widely recognized port number for use by VNC software. However, in certain

circumstances it may be advantageous to alter this number - see Security issues

with ports for more details.

Media Access Control address – this is the unique and unchangeable code that

was hard coded within your ServSwitch CX Uno IP unit when it was built. It

consists of six 2-digit hexadecimal (base 16) numbers separated by colons. A

section of the MAC address identiﬁes the manufacturer, while the remainder is

effectively the unique electronic serial number of your particular unit.

Note: The VNC port and HTTP port can be set to the same port number in order

to simplify router and ﬁrewall conﬁguration. If this is done then the ServSwitch

CX Uno IP will “listen” for both types of trafﬁc on the single port.

Use DHCP

DHCP stands for ‘Dynamic Host Conﬁguration Protocol’. Its function is

particularly useful when connecting to medium size or larger networks, such

as the Internet. When this option is selected, your ServSwitch CX Uno IP will

attempt to locate a DHCP server on the network. If such a server is located,

it will supply three things to the ServSwitch CX Uno IP: an IP address, an IP

network mask (also known as a Subnet mask) and a Gateway address. These

are not usually granted permanently, but on a ‘lease’ basis for a ﬁxed amount

of time or for as long as the ServSwitch CX Uno IP remains connected and

switched on. Discover allocations.

HTTP Port

This is the logical link through which communications with a remote web

browser will be channelled. The default setting of 80 is an established standard

for web (HTTP – HyperText Transfer Protocol) trafﬁc though this can be changed

to suit your local network requirements.

Clear IP Access Control

This option removes all entries from the IP access control feature within the

ServSwitch CX Uno IP. The IP access control feature (conﬁgurable by a global

admin user) allows certain network address ranges to be denied access to the

ServSwitch CX Uno IP. If set incorrectly, it is possible to exclude all network users

and so this option provides an emergency recovery point.

IP Address

This is the identity of the ServSwitch CX Uno IP within a network. The IP address

can be thought of as the telephone number of the ServSwitch CX Uno IP. Unlike

the MAC address, the IP address can be altered to suit the network to which it is

connected. It can either be entered manually or conﬁgured automatically using

the DHCP option. When the DHCP option is enabled, this entry is unavailable.

This page allows you to manage up to sixteen separate accounts.

2 Click the ‘Conﬁgure’ button in the top right corner.

3 Click the ‘User Accounts’ option.

The ﬁrst of the sixteen accounts is the admin account and is the only account

with access rights to the conﬁguration menus. The user name and access rights

are ﬁxed for the admin account, the only change possible for this account is the

password.

There are ﬁfteen user account positions.

User Name

All user names must consist of lower case characters or numbers only. No

symbols or upper case characters are permissible. The user name can be

between 1 and 16 characters in length.

Password

Passwords are case sensitive and can include certain keyboard symbols. The

password can be between 1 and 16 characters in length. It is important to note,

however, that the password background remains shaded in amber while the

ServSwitch CX Uno IP considers your entered password to be too easy to guess.

A suitable password is best constructed using a mixture of more than 6 letters,

numbers and punctuation characters.

Conﬁrm Pwd

Re-enter your password here to conﬁrm that it is correct.

Local

When ticked, the selected user can gain access using the local KVM console

directly connected to the ServSwitch CX Uno IP unit.

Advanced unit conﬁguration

Click this button to display advanced options that do not normally require alteration.

Mouse Latency Allowance

This option is used during calibration to account for latency delays (caused

as signals pass through a device) introduced by some KVM switches from

alternative manufacturers.

During calibration, the ServSwitch CX Uno IP waits for 40ms after each mouse

movement before sampling the next. If a KVM device adds a signiﬁcant delay to

the ﬂow of data, the calibration process can be lengthened or may fail entirely. The

value entered here is added to (or subtracted from) the default 40ms sampling time.

Note: You can enter negative values (down to -40) in order to speed up the

calibration process when using fast KVM switches. Use this option with caution

as it can adversely affect the calibration process.

Mouse Rate

Deﬁnes the rate at which mouse movement data are transmitted to the system. The

default option is 20ms, which equates to 50 mouse events per second. This default

rate can prove too fast when passed through certain connected KVM switches from

alternative manufacturers. In such cases, data are discarded causing the local and

remote mouse pointers to drift apart. If this effect is encountered, increase the mouse

rate to around 30ms (data are then sent at a slower rate of 33 times per second).

Background Refresh Rate

Use the arrow keys to alter the refresh rate for screen images via remote links. This

allows you to tailor the screen refresh to suit the network or modem connection

speeds. The options are: Slow, Medium, Fast or Disabled. When the disabled

option is selected, the remote users will need to manually refresh the screen.

Note: When a low connection speed is detected, the background refresh is

automatically disabled, regardless of the settings of this option.

To get here

1 Using VNC viewer or a browser, log on as the ‘admin’ user.

Single Mouse Mode Mouse Switch

Allows you to select the mouse button combination that can be used to exit from

single mouse mode (when active).

2 Click the ‘Conﬁgure’ button in the top right corner.

3 Click the ‘Unit Conﬁguration’ option.

4 Click the ‘Advanced Unit Conﬁguration’ option.

Behaviour for admin connections when limit reached

Force VNC Protocol ꢂ.ꢂ

IMPORTANT: The use of this option is not recommended. Protocol 3.3 is a legacy

version that does not offer any encryption.

Determines what should occur when four global connections already exist and

a ﬁfth, administrator connection attempt is made. Options are: Replace oldest

connection, Replace newest connection and Don’t replace. Only non-administrator

connections can be terminated in this way.

Idle Timeout

Determines the period of inactivity on a global connection before the user is logged

out. The idle timeout period can be set to any time span, expressed in minutes.

Note: The Screensaver option serves a similar purpose for local connections.

Use VESA GTF

When ticked, the VESA Generalized Timing Formula will be used to help

determine the correct input video resolution and timing details. See Appendix 9

for a list of all supported video modes.

Protocol Timeout

Sets the time period by which responses should have been received to outgoing

data packets. If the stated period is exceeded, then a connection is considered

lost and terminated.

Upgrade ﬁrmware

Places the unit into upgrade mode. See Upgrading ServSwitch CX Uno IP

models.

Time & date conﬁguration

This page allows you to conﬁgure all aspects relating to time and date within the

ServSwitch CX Uno IP unit.

Timezone speciﬁer

Optionally enter a recognized timezone speciﬁer related to the current position

of the ServSwitch CX Uno IP unit. When an NTP server is used, the speciﬁer will

be used to provide the correct real time.

The timezone speciﬁer takes the following form:

std offset dst [offset],start[/time],end[/time]

The std and offset specify the standard time zone, such as GMT and 0, or CET

and -1, or EST and 5, respectively.

The dst string and [offset] specify the name and offset for the corresponding

Daylight Saving Time zone; if the offset is omitted, it defaults to one hour ahead

of standard time.

The remainder of the speciﬁcation describes when Daylight Saving Time is in

effect. The start ﬁeld is when Daylight Saving Time goes into effect and the

end ﬁeld is when the change is made back to standard time. The most common

format used for the daylight saving time is: Mm.w.d

Where: m speciﬁes the month and must be between 1 and 12. The day d

must be between 0 (Sunday) and 6. The week w must be between 1 and 5;

week 1 is the ﬁrst week in which day d occurs, and week 5 speciﬁes the last d

day in the month.

The time ﬁelds specify when, in the local time currently in effect, the change to

the other time occurs. If omitted, the default is 02:00:00.

Typical examples are:

UK:

GMT0BST,M3.5.0/1,M10.5.0/2

CET-1CEST,M3.5.0/2,M10.5.0/3

EST5EDT,M3.2.0/2,M11.1.0/2

Network conﬁguration

To get here

1 Using VNC viewer or a browser, log on as the ‘admin’ user.

This page allows you to conﬁgure the various aspects of the IP port and its

relationship with the local network.

2 Click the ‘Conﬁgure’ button in the top right corner.

3 Click the ‘Network Conﬁguration’ option.

IP Address

This is the identity of the ServSwitch CX Uno IP within a network. The IP

address can be thought of as the telephone number of the ServSwitch CX Uno

IP. Unlike the MAC address, the IP address can be altered to suit the network

to which it is connected. It can either be entered manually or conﬁgured

automatically using the DHCP option. When the DHCP option is enabled, this

entry is greyed out.

IP Network Mask

Also often called the subnet-mask, this value is used alongside the IP address

to help deﬁne a smaller collection (or subnet) of devices on a network. In this

way a distinction is made between locally connected devices and ones that are

reachable elsewhere, such as on the wider Internet. This process helps to reduce

overall trafﬁc on the network and hence speed up connections in general.

IP Gateway

This is the address of the device that links the local network (to which the

ServSwitch CX Uno IP is connected) to another network such as the wider

Internet. Usually the actual gateway is a network switch or router and it will be

used whenever a required address lies outside the current network.

VNC Port

MAC address

This is the logical link through which communications with a remote VNC viewer

will be channelled (see What is a port?). The default setting is 5900 which is

a widely recognized port number for use by VNC software. However, in certain

circumstances it may be advantageous to alter this number - see ‘Security issues

with ports’ for more details.

Media Access Control address – this is the unique and unchangeable code that

was hard coded within your ServSwitch CX Uno IP unit when it was built. It

consists of six 2-digit hexadecimal (base 16) numbers separated by colons. A

section of the MAC address identiﬁes the manufacturer, while the remainder is

effectively the unique electronic serial number of your particular unit.

HTTP Port

Use DHCP

This is the logical link through which communications with a remote web

browser will be channelled (see What is a port?). The default setting of 80 is an

established standard for web (HTTP – HyperText Transfer Protocol) trafﬁc though

this can be changed to suit your local network requirements.

DHCP is an acronym for ‘Dynamic Host Conﬁguration Protocol’. Its function is

particularly useful when connecting to medium size or larger networks, such

as the Internet. When this option is selected, your ServSwitch CX Uno IP will

attempt to locate a DHCP server on the network. If such a server is located,

it will supply three things to the ServSwitch CX Uno IP: an IP address, an IP

network mask (also known as a Subnet mask) and a Gateway address. These

are not usually granted permanently, but on a ‘lease’ basis for a ﬁxed amount

of time or for as long as the ServSwitch CX Uno IP remains connected and

switched on. Discover allocations.

IP Access Control

This section allows you to optionally specify ranges of addresses which will

or won’t be granted access to the ServSwitch CX Uno IP. If this option is left

unchanged, then the default entry of ‘+0.0.0.0/0.0.0.0’ ensures that access from

all IP addresses will be permitted. See Setting IP access control for details.

Setting IP access control

The golden rule with this feature is ‘Include before you exclude’ or to put it

another way ‘Arrange allowed addresses in the list before the denied addresses’.

To deﬁne a new IP access control entry

1 Click the Add button to display a popup dialog:

This is because the positions of entries in the list are vitally important. Once a

range of addresses is denied access, it is not possible to make exceptions for

particular addresses within that range. For instance, if the range of addresses

from A to F are denied access ﬁrst, then the address C could not be granted

access lower down the list. Address C needs to be placed in the list before the

denied range.

IMPORTANT: This feature should be conﬁgured with extreme caution as it is

possible to deny access to everyone. If such an error occurs, see Clearing IP

access control for details about how to regain access.

Network/Address

Mask

Access

Enter the network address

that is to be allowed or denied

access. If a range of addresses

is being speciﬁed then specify

any one of the addresses

within the range and use the

Mask entry to indicate the size

of the range.

Enter an IP network mask

that indicates the range of

addresses that are to be

allowed or denied access.

For instance, if only a single

speciﬁed IP address were to be

required, the mask entry would

be 255.255.255.255 in order

to specify a single location. See

Calculating the mask for IP

access control for details.

Use the arrow buttons to

select either ‘Allow’ or

‘Deny’ as appropriate.

In the list, access control addresses preﬁxed by ‘+’ are allow entries while those

preﬁxed by ‘– ‘ are deny entries.

2 Enter the base network address, the mask and select the appropriate

access setting.

3 Click the OK button.

To reorder access control entries

IMPORTANT: When reordering, ensure that any speciﬁc allowed addresses are

listed higher in the list than any denied addresses. Take care not to invoke any

deny access settings that would exclude valid users.

To get here

1 Using VNC viewer or a browser, log on as the ‘admin’ user.

2 Click the ‘Conﬁgure’ button in the top right corner.

3 Click the ‘Network Conﬁguration’ option.

In the access control list, click on the entry to be moved.

Click the Up or Down buttons as appropriate.

Appendix 3 - VNC viewer connection options

When you are connecting to the

ServSwitch CX Uno IP using the

VNC viewer, a number of options

are available.

Color/Encoding

Auto select

When ticked, this option will

examine the speed of your

connection to the ServSwitch CX

Uno IP and apply the most suitable

encoding method. This option

is suggested for the majority of

installations.

Click here to

access the options

There are six tabbed pages of options:

• Color/Encoding

• Inputs

Preferred encoding

There are three manually selectable

encoding methods which are

accessible when the Auto select

option is unticked.

• Scaling

• Misc

• Identities

• ZRLE – This is a highly

compressed method that is

best suited to slow modem

connections.

• Load/Save

• Hextile – This method offers

better performance than the ZRLE when used over a high speed network

because there is no need for the ServSwitch CX Uno IP to spend time highly

compressing the data.

• Raw – This is a primitive, uncompressed method that is mainly used for

technical support issues. You are recommended not to use this method.

Color level

This section allows you to select the most appropriate color level for the speed

of the connection to the ServSwitch CX Uno IP. Where the connection speed

is slow or inconsistent there will be a necessary compromise between screen

response and color depth.

• Full – This mode is suitable only for fast network connections and will pass

on the maximum color depth being used by the host system.

• Medium (ꢁꢄꢅ colors) – This mode reduces the host system output to a 256

color mode and is more suitable for ISDN and fast modem connections.

• Low (ꢅꢃ colors) – This mode is suitable for slower modem connections and

reduces the host system output to 64 colors.

IMPORTANT: If you make any changes to the options given here and wish to

retain them for successive connection sessions, you must save the changes.

To do this, change to the ‘Load/Save’ tab and click the ‘Save’ button within the

‘Default’ section.

• Very low (ꢇ colors) – This mode provides very rudimentary picture

quality and hardly any speed advantage over the 64 color setting. You are

recommended not to use this mode.

and you will notice that the remote cursor will catch up with the local cursor

roughly once every second.

When selected, allows keyboard,

mouse and clipboard data to be

transferred between server and

viewer systems.

Enable 3-button mouse emulation

Disable all inputs (view-only

mode)

When selected, prevents control

data being passed between server

and viewer. Viewer can display the

server output, but cannot control it.

This feature allows you to use a 2-button mouse to emulate the middle button

of a 3-button mouse. When enabled, press the left and right mouse buttons

simultaneously to create a middle button action. You are advised to generally

use a 3-button mouse.

Pass special keys directly to server

When ticked, ‘special’ keys (the Windows key, the Print Screen key, Alt+Tab,

Alt+Escape and Ctrl+Escape) are passed directly to the ServSwitch CX Uno IP

rather than being interpreted locally.

Customize

Allows you to select which data can

be transferred between server and

viewer.

Appendix 6 – Addresses, masks and ports

Net masks

IP address, network masks and ports are all closely linked in the quest for one

device to ﬁnd another across disparate network links.

The net mask (or sub-net mask) informs a device as to its own position within a

network. From this it can determine whether any other device is within the same

local network or is situated further aﬁeld.

IP addresses

Taking the telephone number analogy given in the IP address section, in order

to use the telephone system efﬁciently, it is vital for you to know your location

relative to the person you are calling. In this way you avoid dialling unnecessary

numbers.

As a rough analogy, consider how you use the telephone system. The phone

number for Black Box in the US is 1-724-746-5500. This number consists of four

distinct parts:

When one network device needs to talk to another, the ﬁrst thing that it will

do is a quick calculation using its own IP address, the other device’s IP address

and its own net mask. Suppose a device with address 192.168.142.154 and

net mask 255.255.255.0 needed to communicate with a device at address

192.168.142.22. The sending device would perform several calculations:

• 1 connects from another country to the US,

• 724 connects into Pennsylvania,

• 746 selects the telephone exchange in Lawrence, and

• 5500 is the unique code for Black Box within Lawrence.

The important parts of the whole number depend on where you are. If you were

based in the same local area as Black Box in the US, there would be no point

in dialling out of the US, or even out of the area. The only part of the whole

number that you are interested in is the ﬁnal part: 5500.

192 168 142 000

192 168 142 22

192 168 142 000

In a similar way to the various parts of the telephone number, the four sections

(or Octets) of every IP address have different meanings or “weights”. Consider

the following typical IP address:

Net mask

Result

192.168.142.154

192 is the most global part of the number (akin to the 1 of the phone number)

and 154 is the most local (similar to the 5500 unique local code of the phone

number).

192.168.142.000 = 192.168.142.000 ? Answer: Yes

Address

is local

When two network devices communicate with each other, they always “dial the

whole number” regardless of their respective locations in a network. However,

they still need to know whether the other device is local to them or not, and this

is where the net mask comes into play.

1 The net mask is used to determine the local and global parts of the sender’s IP

address. Where there is 255 in the mask, the corresponding address slips through,

where there is a 0, it is blocked.

2 Where the net mask was 0, the corresponding part of the result is also zero - this

section is now known to be the local part of the IP address.

3 The same process is carried out for the destination address, again using the sender’s

net mask. Now the local parts of both addresses have been equalized to zero,

because their values are not important in determining whether they are both in the

same local network.

4 The results of the two net mask operations are now compared, if they match, the

destination is local. If not, then the sender will still use the same full destination IP

address but will also ﬂag the message to go via the local network gateway and out

into the wider world.

The reason for doing this? It makes the network, as a whole, much more

efﬁcient. If every message for every recipient was shoved straight out onto the

Internet, the whole thing would grind to a halt within seconds. Net masks keep

local trafﬁc just that - local.

Net masks - the binary explanation

To really understand the operation of a net mask it is necessary to delve deeper

into the life blood of computers – binary; this is native digital, where everything

is either a 1 (one) or 0 (zero), on or off, yes or no.

The net mask operation described on the previous page is known as a ‘bit-wise

AND function’. The example of 255.255.255.0 is handy because the last octet

is completely zero and is “clean” for illustrative purposes. However, actual net

mask calculations are carried out, not on whole decimal numbers, but bit by bit

on binary numbers, hence the term ‘bit-wise’. In a real local network, a net mask

might be 255.255.255.240. Such an example would no longer be quite so clear,

until you look at the net mask in its binary form:

11111111.11111111.11111111.11110000

In this case, the four zeroes at the end of the net mask indicate that the local

part of the address is formed by only the last four bits. If you use the diagram

from the previous example and insert the new net mask, it will have the

following effect on the ﬁnal result:

Decimal octet prior to AND

192 168 142 144

Binary equivalent of ꢀꢄꢃ

10011010

Inside a bit-wise AND function

When you “open up” the last octet

of the net mask and look at the

binary inside, you can see the last

four zero bits preventing any 1’s in

the address from falling through.

10010000

Binary octet after AND

operation with net mask

Decimal equivalent of ꢀ00ꢀ0000

144

Thus, when 154 is bit-wise ANDed with 240, the result is 144. Likewise, any

local address from 192.168.142.144 through to 192.168.142.159 would

produce exactly the same result when combined with this net mask, hence they

would all be local addresses. However, any difference in the upper three octets

or the upper four bits of the last octet would slip through the mask and the

address would be ﬂagged as not being local.

Calculating the mask for IP access control

The permissible mask values (for all octets) are as follows:

The IP access control function uses a standard IP address and a net mask

notation to specify both single locations and ranges of addresses. In order to

use this function correctly, you need to calculate the mask so that it accurately

encompasses the required address(es).

2 addresses

Single locations

252

4 addresses

Some of the simplest addresses to allow or deny are single locations. In this case

you enter the required IP address into the ‘Network/Address’ ﬁeld and simply

enter the ‘Mask’ as 255.255.255.255 (255 used throughout the mask means

that every bit of the address will be compared and so there can only be one

unique address to match the one stated in the ‘Network/Address’ ﬁeld).

240

16 addresses

224

32 addresses

192

64 addresses

128

128 addresses

256 addresses

All locations

The other easy setting to make is ALL addresses, using the mask 0.0.0.0 As

standard, the IP access control section includes the entry: 0.0.0.0/0.0.0.0

If the access control range that you need to deﬁne is not possible using one

address and one mask, then you could break it down into two or more entries.

Each of these entries could then use smaller ranges (of differing sizes) that,

when combined with the other entries, cover the range that you require.

The purpose of this entry is to include all IP addresses. It is possible to similarly

exclude all addresses, however, take great care not to do this as you instantly

render all network access void. There is a recovery procedure should this occur.

Address ranges

For instance, to accurately encompass the range in the earlier example:

Although you can deﬁne ranges of addresses, due to the way that the mask

operates, there are certain restrictions on the particular ranges that can be set.

For any given address you can encompass neighbouring addresses in blocks of

either 2, 4, 8, 16, 32, 64, 128, etc. and these must fall on particular boundaries.

For instance, if you wanted to deﬁne the local address range:

192.168.142.67 to 192.168.142.93

You would need to deﬁne the following six address and mask combinations in

the IP access control section:

Network/address entry Mask entry

192.168.142.67 to 192.168.142.93

192.168.142.67

192.168.142.68

192.168.142.72

192.168.142.80

192.168.142.88

192.168.142.93

255.255.255.255

255.255.255.252

255.255.255.248

255.255.255.252

255.255.255.255

deﬁnes 1 address (.67)

The closest single block to cover the range would be the 32 addresses from:

192.168.142.64 to 192.168.142.95.

deﬁnes 4 addresses (.68 to .71)

deﬁnes 8 addresses (.72 to .79)

deﬁnes 8 addresses (.80 to .87)

deﬁnes 4 addresses (.88 to .92)

deﬁnes 1 address (.93)

The mask needed to accomplish this would be: 255.255.255.224

When you look at the mask in binary, the picture becomes a little clearer. The

above mask has the form: 11111111.11111111.11111111.11100000

Ignoring the initial three octets, the ﬁnal six zeroes of the mask would ensure

that the 32 addresses from .64 (01000000) to .95 (01011111) would all be

treated in the same manner. See Net masks - the binary explanation for

details.

When deﬁning a mask, the important rule to remember is:

There must be no ‘ones’ to the right of a ‘zero’.

For instance, (ignoring the ﬁrst three octets) you could not use a mask that had

11100110 because this would affect intermittent addresses within a range in an

impractical manner. The same rule applies across the octets. For example, if you

have zeroes in the third octet, then all of the fourth octet must be zeroes.

Ports

Security issues with ports

The settings of port numbers become important when the ServSwitch CX Uno IP

is situated behind a network ﬁrewall. In order for a remote VNC viewer or web

browser to make contact with your ServSwitch CX Uno IP, it is necessary for the

ﬁrewall to allow communication through a particular numbered port to occur.

If you accept the analogy of IP addresses being rather like telephone numbers,

then think of ports as extension numbers. In a company of any size, you

generally wouldn’t expect the accounts department to share the same telephone

with the technical department. Although their calls may all be related to the

same company, they concern very different aspects of that company.

One speciﬁc function of ﬁrewalls is to restrict access to ports in order to prevent

malicious attackers using them as a route into your network. Every new port

that is opened offers a new possibility for hackers and so the number of

accessible ports is purposefully kept to a minimum. In such cases, it may be

advantageous to change one or both ServSwitch CX Uno IP ports to use the

same number. The other alternative is to place the ServSwitch CX Uno IP unit

outside the ﬁrewall and take full advantage of its secure operation features – see

Networking issues for details.

It is the same with IP network connections. Although you have only one network

link into your computer and only one IP address (phone number), you are

probably performing many different tasks through that one link, often at the

same time. Thus, when you browse the web your outgoing requests and the

incoming information are all channelled through port 80. When you send an

email, it travels through port 25 and when you transfer ﬁles you are, without

knowing it, using port 20.

IMPORTANT: The correct conﬁguration of routers and ﬁrewalls requires

advanced networking skills and intimate knowledge of the particular network.

Black Box cannot provide speciﬁc advice on how to conﬁgure your network

devices and strongly recommend that such tasks are carried out by a qualiﬁed

professional.

At the “border crossing” between the wider Internet and every local network

attached to it, there is a router that is usually combined with a ﬁrewall. One of

its main tasks is to direct incoming trafﬁc to the correct place within its local

network. A key piece of information to help it do this is the port number:

User with VNC viewer accesses

IP address: 129.7.1.10 (this

automatically uses port 5900).

Keypad keys (see ‘Using abbreviations’)

KP_Insert KP_Delete KP_Home KP_End KP_PageUp

Using abbreviations

KP_PageDown KP_Up KP_Down KP_Left KP_Right KP_Enter

To reduce the length of the key deﬁnitions, any unique abbreviation for a

key can be used. For example: “scroll”, “scr” and even “sc” all provide an

identiﬁable match for “ScrollLock” whereas “en” could not be used because it

might mean “Enter” or “End” (“ent” would be suitable for “Enter”).

KP_Add KP_Subtract KP_Divide KP_Multiply

KP_0 to KP_9

which have special meanings, as explained below.

Codes with special meanings

+ means press down the key that follows

Appendix 9 – Supported video modes

The following video modes are supported and can be automatically conﬁgured

by the ServSwitch CX Uno IP units. If a recognized video mode cannot be found,

the ServSwitch CX Uno IP will gradually change some of the key parameters

to discover whether a video lock can be achieved. Support for VESA GTF

(Generalized Timing Formula) is available and can be enabled via the Advanced

Unit Conﬁguration screen.

The half width video modes capture every other pixel. These are not generally

recommended for normal use but may be used for emergency access to high

resolution, high frequency system screens. Half width screens can be expanded

to normal width using the scaling features of the viewer.

A Category 5 (or better) twisted pair cable must be used to connect the units in

order to maintain compliance with radio frequency energy emission regulations

and ensure a suitably high level of immunity to electromagnetic disturbances.

All other interface cables used with this equipment must be shielded in order

to maintain compliance with radio frequency energy emission regulations and

ensure a suitably high level of immunity to electromagnetic disturbances.

European EMC directive 89/336/EEC

FCC Compliance Statement (United States)

This equipment has been tested and found to comply with the limits for a class

A computing device in accordance with the speciﬁcations in the European

standard EN55022. These limits are designed to provide reasonable protection

against harmful interference. This equipment generates, uses and can radiate

radio frequency energy and if not installed and used in accordance with the

instructions may cause harmful interference to radio or television reception.

However, there is no guarantee that harmful interference will not occur in a

particular installation. If this equipment does cause interference to radio or

television reception, which can be determined by turning the equipment on

and off, the user is encouraged to correct the interference with one or more

of the following measures: (a) Reorient or relocate the receiving antenna. (b)

Increase the separation between the equipment and the receiver. (c) Connect

the equipment to an outlet on a circuit different from that to which the receiver

is connected. (d) Consult the supplier or an experienced radio/TV technician for

help.

This equipment generates, uses and can radiate radio frequency energy

and if not installed and used properly, that is, in strict accordance with the

manufacturer’s instructions, may cause interference to radio communication.

It has been tested and found to comply with the limits for a class A computing

device in accordance with the speciﬁcations in Subpart J of part 15 of FCC rules,

which are designed to provide reasonable protection against such interference

when the equipment is operated in a commercial environment. Operation of this

equipment in a residential area may cause interference, in which case the user at

his own expense will be required to take whatever measures may be necessary

to correct the interference. Changes or modiﬁcations not expressly approved by

the manufacturer could void the user’s authority to operate the equipment.

Canadian Department of Communications RFI statement

This equipment does not exceed the class A limits for radio noise emissions from

digital apparatus set out in the radio interference regulations of the Canadian

Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant

les limites applicables aux appareils numériques de la classe A prescrites dans

Certiﬁcation notice for equipment used in

Canada

The Canadian Department of Communications label identiﬁes certiﬁed

equipment. This certiﬁcation means that the equipment meets certain

telecommunications-network protective, operation, and safety requirements.

The Department does not guarantee the equipment will operate to the user’s

satisfaction.

Before installing this equipment, users should ensure that it is permissible to be

connected to the facilities of the local telecommunications company.

The equipment must also be installed using an acceptable method of

connection. In some cases, the company’s inside wiring associated with a

single-line individual service may be extended by means of a certiﬁed connector

assembly (extension cord). The customer should be aware that compliance with

the above conditions may not prevent degradation of service in some situations.

Repairs to certiﬁed equipment should be made by an authorized Canadian

maintenance facility—in this case, your supplier. Any repairs or alterations

made by the user to this equipment, or equipment malfunctions, may give

the telecommunications company cause to request the user to disconnect the

equipment.

Users should ensure for their own protection that the electrical ground

connections of the power utility, telephone lines, and internal metallic water

pipe system, if present, are connected together. This precaution may be

particularly important in rural areas.

CAUTION:

Users should not attempt to make such connections themselves, but should

contact the appropriate electric inspection authority, or electrician, as

appropriate.

The LOAD NUMBER (LN) assigned to each terminal device denotes the

percentage of the total load to be connected to a telephone loop which is used

by the device, to prevent overloading. The termination on a loop may consist of

any combination of devices, subject only to the requirement that the total of the

load numbers of all the devices does not exceed 100.
