Configuration
SVxx54DX4I offers four distinct methods for configuring the unit for
your network. Which method will work best will depend on your level of
experience and your specific network configuration.
Using the On-Screen Display
Upon initial boot, you will require an administrative username and
password. By default, the username and password are both: admin. You
will be given the opportunity to change the password (recommended),
once the configuration is complete.
The DHCP assigned IP Address will be visible at this time, at the bottom
of the screen. If no DHCP server is detected, a factory assigned IP
address will be displayed in its place (10.0.0.15 by default). Please make
note of the assigned IP address, as you will need to enter it into your
web browser to access the Web Interface.
Once the username and password (admin, admin) have been entered,
a status window will appear. Press “I” to proceed to the Main Menu
screen.You will be asked if you wish to change the default password.
Select Yes or No as appropriate, then press Enter to continue. If no

DHCP connection is present, press the Setup button on the rear panel of
SVxx54DX4I to display the Main Menu screen, where you will be given
several basic setup options:
If static IP addresses are assigned, you will likely need to change the
Net Mask, IP Address and other details, prior to connecting via your Web
browser. If this is the case, connect a local keyboard (USB or PS/2) and
press the Enter key.
To configure SVxx54DX4I to your required network settings, use the
Network Setup Wizard. To select from the menus provided, use the
arrow keys on your keyboard. At any time, you can return to the previous
menu by pressing the Page Up key.

Using DHCP
This method requires that your network implement DHCP (Dynamic Host
Configuration Protocol), usually on a server or network access device
such as a router, that dynamically allows devices to join the network
without pre-configuration.
Please note: The OSD will report the IP address as assigned by the DHCP
server. If you have a directly connected monitor, the following steps are
not required.
If the unit is powered on and connected to the network via LAN port on
the rear panel, it will automatically attempt to lease an IP address using
DHCP. Before you can begin the configuration process, you will need to
access the DHCP log from your file server or another device that acts
as the DHCP server on the network. (You may need to contact your
Network Administrator for this information).
A simple DHCP log should supply (at minimum) three essential details:
IP address, MAC address, and device (or machine) name for the
computers and other devices connected to your network.
The values for the SVxx54DX4I tested above are as follows:
IP Address: 192.168.22.4
MAC Address: 00-0E-C5-00-08-1A
Device Name: (none)
The easiest way to identify your SVxx54DX4I on the network is by its
MAC address - a unique hardware identifier that is specific to your unit.
The MAC address of the unit can be found using the OSD setup screen;
5
Download from Www.Somanuals.com. All Manuals Search And Download.
please write this number down and keep it for future reference. Once
you locate the MAC address of your unit in the DHCP log, you can match
it to its leased IP address and proceed with the Web configuration.
Please note:
• Once you have located the IP address of the SVxx54DX4I and wish
to proceed with the Web configuration, do not power off the unit or
your DHCP server, since the Enterprise Class KVM might lease a
different IP address. Should this happen, re-examine the DHCP log
to verify the IP address again.
• DHCP functionality is not affected if you also connected the WAN
port on the SVxx54DX4I to your network (see below).However, it is not
recommended that you connect both the WAN and LAN ports to the
same network segment.
Web Configuration Using Static IP
The DHCP access method described above would not apply to networks
that rely on static IP addresses (every device has a pre-configured IP
address that does not change).To accommodate this type of installation,
the WAN port on the rear panel of the SVxx54DX4I is factory-configured
with its own IP address.
Please note:
If you connected the LAN port on the rear panel of the unit to your
network, but did not connect the WAN port, you must disconnect the
Ethernet cable from the LAN port and move it to the WAN port before
attempting a static IP installation. (If desired, you can return the cable
to the LAN port if you configure it with a static IP address during the
configuration process.
If you have connected both the LAN and WAN ports on the unit to your
network, you may proceed with a static IP Web configuration.

The following are the factory default values for the WAN port:
IP Address: 192.168.1.123
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254
Broadcast: 192.168.1.255
ToaccesstheWebconfigurationforthisproduct,youwillneedtoconfigure
the workstation you are using to the same subnet (255.255.255.0) and
also assign it a valid IP address (i.e. 192.168.1.100). For details on how
to change the IP address of your computer (if necessary), consult your
documentation or System Administrator for assistance.
Please note:
• In order to avoid a conflict, it is advisable to verify whether another
device on your network is using the same IP address as the
SVxx54DX4I before connecting it to the network.
• Should an IP address conflict occur with another device on the
network, power off the conflicting device or assign it another IP address
before continuing the installation.
• If you are configuring more than a single SVxx54DX4I unit using the
factory default settings on the WAN port, they cannot be connected to
the network at the same time, as they will use the same IP address.
• Not all IP addresses are valid for a given subnet. If you are required
to change your subnet (and therefore IP address) to configure the unit,
be sure the IP address you choose is within the allowable range for the
255.255.255.0 subnet.
Once your computer is configured to the same subnet as SVxx54DX4I,
you can use the IP address 192.168.1.123 to access the Web
configuration system.

Connecting the Host Computer to the Unit
Please note: It is strongly recommended that all systems supporting
USB use the USB server interface modules (see StarTech.com part
# SV5USBM). PS/2 modules (SV5PS2M) are available for legacy
systems.
1. If present, disconnect the existing monitor and PS/2 or USB keyboard/
mouse from the host computer.
2. Connect the PS/2 keyboard and mouse or USB connector to the host
computer.
3. Connect the VGA connector to the host computer.
4. Connect the Server Interface Module (SV5PS2M or SV5USBM) to the
KVM with a straight through CAT5 cable.
5. Power on the host computer.
Disabling Mouse Acceleration on the Host Computer
Please note: If the SV5USBM (USB version) is used with a modern
Windows O/S computer, there is no need to disable mouse acceleration.
Only PS/2 systems, or USB systems with Linux or UNIX operating systems
require this change. Ignore this section in that case.
Many operating systems offer a feature called mouse acceleration,
allowing the user to adjust the responsiveness of the cursor on the screen
in relation to physical movements of the mouse. While this is usually a
beneficial interface enhancement, it will interfere with the operation of
the SVxx54DX4I and should be disabled on the host computer before a
remote session is attempted.
To disable mouse acceleration for the host computer operating system:
Windows 98
1. From the Control Panel, click on Mouse.
2. From Mouse Properties, click on the Motion tab.
3. Make sure the Pointer speed bar is centered and Acceleration is set to
None.
8

Windows 2000
1. From the Control Panel, click on Mouse.
2. From Mouse properties, click on the Motion tab.
3. Make sure that the Pointer speed bar is centered and Acceleration is
set to None.
Windows XP and Windows Server 2003
Go to Pointer Options and turn off Enhance Pointer Precision. Ensure
that the pointer speed bar is centered.
Linux, UNIX and X-Windows
Add this command to your xinitrc, xsession or other startup script:
xset m 0/0 0
Also, under Pointer Control, verify that acceleration and threshold are
zero, with the command:
xset q
Connecting the SV5CONS Remote User Station (Optional)
The remote user station allows for extended local control of attached
host machines. To connect a remote user station:
1. Connect a VGA monitor to the front of the SV5CONS.
2. Connect a USB keyboard and mouse device. (Please note that some
keyboards and mice may not work due to non-standard USB
implementation)
3. Connect a straight through CAT5 cable to port A on the user-station.
4. Connect the power to the remote user station.
Please Note: The remote user station operates just like the local user
port, except a few extra commands on OSD:

<CTRL> <CTRL> <C> Cause auto calibration to restart
<CTRL><CTRL> <A> Go to A port
<CTRL> <CTRL> <B> Go to B port
To switch A/B connections at any time (even
<CTRL> + <Space>
if no KVM OSD is shown, or if current KVM is
powered down).
Please note that you may notice a pattern of vertical bars briefly
displayed during distance calibration; this is normal. As such, please
disregard.
Using the Web Interface
The Web interface offers the most intuitive way to configure the
SVxx54DX4I, as it provides a Java-based VNC client that can be used
to control the host computer from a remote location, as well as support
for any industry-standard HTML Web browser.
You can access the Web interface by opening your Web browser
and entering the IP address of the SVxx54DX4I you wish to access/
configure. The IP address will be either the address assigned by your
DHCP server as identified in the previous section, or 192.168.1.123 (if
your network uses static IP addressing).
Using SVxx54DX4I’s web interface requires a browser, with cookies
and JavaScript enabled. To start the Java VNC client, login to the Web
configuration interface and click on the thumbnail of the desktop on the
Home menu, or click on the Connect button, located in the Main Menu.
You may need to upgrade Java support in your browser; however, most
modern browsers come with a version of Java that is compatible with
this application. The Java VNC client makes a connection back to the
SVxx54DX4I unit over port 5900 (by default) or 15900 (if encrypted).
The encrypted connection is a standard SSL (Secure Socket Layer)
encrypted link that encrypts all data from the session, including the
actual video pictures.

Download from Www.Somanuals.com. All Manuals Search And Download.
Because Java is considered a “safe” programming language, the Java
VNC client has some limitations. Certain special keystrokes cannot be
sent, such as “Scroll Lock” on the keyboard.
This client software requires the use of Java 2 (JRE 1.4) to enable
features like wheel mouse support. Sun Microsystems’s Java site, www.
java.com, is an excellent resource to ensure your browser and operating
system are updated accordingly.
The Login Screen
Before you can access the Web configuration interface, you must
enter a username and password. The default username and password
as shipped from the factory are username admin, with a password of
admin.
Please Note: Before the login screen appears, your Web browser may
display a warning about an invalid security certificate. This does not
affect the security of your data in any way.
Whenever you are prompted about a certificate security problem by your
browser or the Java VNC client, always choose the option to continue.

The SVxx54DXI4 supports four / five independence non-blocking
accesses to 16/32 servers. These four / five independence non-blocking
accesses can be controlled from six different sources, and these are one
Local VGA, one User 1, and four VNC-(A, B, C and D)s.
The access priority and combination from these six sources to the four
/ five independent non-blocking accesses is shown in the following
diagram:
1. The SV3254DXI4 has two 16:4 (16 input and 4 output) matrices. The
SV1654DX4I CAT5 switch has one 16:4 matrix.
13

2. The ways of connecting the six different sources to the 4 output of the
16:4 matrix are:
a. Local VGA is connected to all 4 outputs of the 16:4 matrix and
will automatically switch between them according to the output
resources.
b. Each of the four VNC-(A, B, C and D)channels are connected to
one of the 4 outputs of the 16:4 matrix.
c. User 1 is connected to the same output as VNC-C. User 1 has
higher priority than VNC-C, which means that VNC-C will not be
available when User 1 is being used.
d. Since the SV3254DXI4 consists of two 16:4 matrix, it can provide
five independence non-blocking accesses as long as they don’t
access the same 16:4 matrix.
3. Both Local VGA and User 1 provide access to the Built-in Terminal
Emulation.

Thumbnails
The Thumbnails screen provides a thumbnail view of connected
computers, and allows you to click through for direct monitoring of any of
the displayed devices. The thumbnails will update periodically.
User Preferences
The User Preferences screen offers several configuration options,
pertaining to the functionality of SVxx54DX4I on a per-user basis. Here,
you will be able to customize settings to optimize overall performance,
(e.g. Encryption options, VNC options, display and bandwidth options
etc.), according to each user’s individual preferences. Please save your
selections by clicking the Save Changes button.
Logout
Clicking on Logout logs you completely out of the SVxx54DX4I interface.
You will have to login again to gain access to the web interface.
File Transfer
The SVxx54DX4I is able to emulate
a virtual USB disk drive on any host
connected using the USB Server
Interface
Module
(SV5USBS).
Depending on configuration, it will
appear to the host as a floppy drive
(1.44MB), an 8MB RAM Disk or a
CD-ROM. The host computer does
not require any special drivers or
other configuration.You can transfer
files to the virtual disk at any time.
Only one computer can access
the disk at a time through the Disk
Control menu in the VNC window.
Files can be uploaded/downloaded through the web interface, while the
disk is ejected.
15
Download from Www.Somanuals.com. All Manuals Search And Download.
SVxx54DX4I will wait until the host is not using the disk, and add or
remove the files.
When the host computer next looks at the drive, it will notice the changes.
You can read files from the virtual disk at any time, as long as the host is
not actively writing to the disk. All of this happens in the background, and
you may treat the virtual disk as a shared drive without any restrictions.
• Access to the files is performed through the web interface. Contents of
the root directory are shown on the home page.You can download files
as you would any file on the web (right-click and Save target as).
• To upload a file, click Browse, select a file, and then click Upload.
• Files and directories may be deleted using the Delete button situated
to their right.
When emulating a floppy disk or RAM Disk, the data is stored in RAM on
the SVxx54DX4I itself. In order to emulate a CD-ROM disk drive, a web
server is required to provide the CD-ROM image data. The Web server
must be accessible to the unit, which communicates with it constantly
as data is needed.
Floppy mode: Choose the Format as floppy button to switch to floppy
mode. Under Windows, the drive will be identified as a “high density
floppy” and will typically be assigned a drive letter of B:
The capacity is limited to 1.44 megabytes in this mode. The purpose
of supporting floppy mode is to permit the use of floppy-disk images
generated by other systems (e.g. the flash BIOS upgrade process is
performed with a special floppy and is bootable, emergency repair disks
are often floppy-based etc.). You can transfer bits from that floppy to
the SVxx54DX4I (use the upload disk image form) and boot from the
special floppy.
RAM Disk mode: Choose the Format as RAM Disk button to switch to
RAM Disk mode. This mode is intended to facilitate simple data transfer
between the remote user and the host computer. It will be recognized by
Windows as an 8MB removable disk and assigned a drive letter.You can
easily drag and drop files up to 8MB in size to this device.
Disk Formats: When you choose the Format as... button, the disk image
stored in RAM is formatted as an empty MS-DOS disk, with a single file
16

called Put files here...TXT.
SVxx54DX4I is able to read most MS-DOS/Windows formatted disks
and presents the files via the Web interface. However, disk emulation
occurs at the lowest level, so other disk formats can be used if you have
the tools needed to create and read the disk images.
At the bottom of the page are the upload and download options for the
entire disk image. Any image that is exactly 1,474,560 bytes long will be
treated as a floppy. Images of other sizes are supported up to 8MB.
CD-ROM Mode:The SVxx54DX4I does not store any data in this mode.
Instead, it emulates a USB CD-ROM drive with a disk inserted.The data
from that disk must be provided by an external web server. You will need
a copy of the CD-ROM contents that you want to emulate as an ISO file.
This is a byte-for-byte copy of track one (the data track) of a data CD-
ROM. The ISO file must be made available on a web server that can be
accessed by SVxx54DX4I.To switch to this mode, type in a URL pointing
to the ISO image, and click on Commit. The system will connect to the
web server and test the file for access. If successful, you will be shown a
short report on the file contents, and the disk will be ready to use.
Currently there is no other way to preview or browse the contents of the
CD-ROM image, except from the host.
CD-ROM Web Server Requirements:
• Data must be hosted on a web server that the SVxx54DX4I can access
directly.
• An image of a bootable CD-ROM disk can be used by the BIOS to boot
an operating system.
• The image file itself may be any size, but it will typically be less than
700Mb. Normally this file will be an ISO image (an ISO-9660 file
system) but any disk image may be used.
• The web server must support“byte ranges”.Persistent connections are
used, if available, as this greatly improves performance. “Read-only”
access is provided; writing is not supported.
• CD-Rom block size must be 2048 bytes. Unfortunately, XA-Data type
tracks are not supported.

Booting from USB Disk:
If the host computer’s BIOS supports USB boot devices, it is possible to
boot from the emulated CD-ROM or floppy - allowing complete operating
system replacement without any on-site intervention.)
The first step is getting a bootable disk image onto the emulated floppy
Please note that each BIOS manufacturer offers varying levels of support
for USB boot devices and may require configuration methods that are
unique (to the manufacturer) in order to utilize this feature. Similarly,
please note that many BIOS’s provide a simplified USB host stack and
offer drivers that may not offer suitable reliability.
or CD-ROM. For CD-ROM images, you will need an .ISO image from a
disk that contains special bits to enable booting (“El Torito” standard).
Nothing special is needed when reading the ISO from a working,
bootable CD-ROM.
To create a bootable floppy, you can format the emulated floppy from the
target system, or read the data from a working boot floppy. This can be
done from Windows using Disk Copy (right click on the drive letter in the
Windows Explorer) or by using a program like “RAWRITE”.
Once you have a bootable image (CD-ROM or floppy) working on the
Enterprise Class KVM unit, you must adjust your BIOS settings to tell it
to boot from a USB device.
Please note: You must select USB CD-ROM as the boot device for
the BIOS, if using a CDROM image and USB Floppy if using a floppy
image.

‘Admin Functions
The Admin functions allow you to access all of the features you will need
to perform an initial configuration of the SVxx54DX4I.
Network Config
DHCP (Dynamic Host Configuration Protocol)
Automatic network configuration using DHCP is: Enabled/Disabled.This
feature applies only to the LAN port on the rear panel and is enabled by
default. When enabled, the unit will automatically configure itself with
an IP address when a DHCP server is present. When disabled, the LAN
port will use the values assigned to it in the IP Addresses and Routing
section described below.
19
Download from Www.Somanuals.com. All Manuals Search And Download.
IP Addresses and Routing
This table allows you to assign IP information for the LAN and WAN
ports separately. If you are using DHCP, the values for the LAN port will
be filled in automatically and any changes made will not affect the setup.
If Ethernet Bridging is enabled, the WAN port will use the same settings
as the LAN port, and any changes will not affect the setup for that port.
Adjusting the setting for the WAN port allows you greater control over
how the SVxx54DX4I is configured for access from outside the local
network, particularly if a firewall or proxy is in use.
Domain Name Server (optional)
This section allows you to specify DNS servers and the default DNS
domain suffix in use on the network. If DHCP is enabled, some of these
values may be supplied automatically.
Clicking the Commit button applies any changes made on this page,
but leaves the old settings active until the next time the unit restarts.
Clicking Make changes effective now applies the changes and restarts
SVxx54DX4I so the new settings take effect immediately.
Ethernet Address (MAC Address)
This is the Ethernet hardware address of the SVxx54DX4I’s LAN/
WAN port. This number is assigned as a factory default, and cannot be
changed.You may need this number to configure your DHCP server.
Ethernet Bridging
When Ethernet Bridging is enabled, the two Ethernet ports are virtually
connected inside the SVxx54DX4I. Packets arriving on either port
that are not meant for it will be forwarded out to the other port, when
appropriate. IEEE-802.1d (Spanning Tree Protocol) is implemented to
avoid broadcast storms and to determine the topology of the network.
You may connect both the WAN and LAN ports to the same logical
network through redundant Ethernet switches. If one switch fails, the
other will be used. When bridging is enabled, both ports share the same
configuration (DHCP or static IP addresses) and the WAN port may not
be separately configured. Using DHCP with Bridging increases boot

User List
• Select which user to change, by clicking on their name.
• Table has summary values:Three stars if there is a password defined
for the user, or else blank. English summary of access rights
(incomplete vs. actual details).
Click the Del button to delete the user. Changes only take effect once
you press Record changes. (Record changes must be pressed for
each user you wish to modify).
Add users:
1. Press reset / new user first (otherwise, you will end up changing an
existing user’s name!).
2. Enter a unique Username (and password if desired).
3. Pick which devices they should be able to access.
4. Usually best to leave all empty except in the this user’s default line.
Important note: The “Hardwired” user account:
If you create a user account with the name hardwired, it can be used
only at the local VGA port and user-stations. This special account is
also provided by default, if the user gives a blank username on the
OSD. If the password is empty on the hardwired account, a local user
can just press Enter twice at the OSD login prompt to get in. Like other
accounts, hardwired may be restricted to view-only or to control only
certain machines.

RADIUS
The RADIUS server requires the
IP address, the UDP port number
(1812 by default, or 1645) and the
shared secret. The shared secret
isusedtoencryptcommunications
and corresponds to a shared
password for the RADIUS server
and the client machine. Two
additional servers may be defined
for backup purposes. Each server
will be tried in order, using the
indicated number of retries and
timeout period, which are configurable on the same page.
Remember to enable RADIUS after configuring it. While RADIUS
authentication is enabled, the locally defined accounts on the

SVxx54DX4I unit will not be used, except for the SSH login. However,
if a user name in the form name.local is given at the RADIUS prompt,
the system will use name, check the password locally and skip RADIUS
authentication. Delete all local accounts to avoid this behavior.
When connecting via VNC, a login screen is generated that asks for a
RADIUS username and password.

• The unit will sometimes reboot as part of the upgrade procedure,
depending on which system component is upgraded.You will have to
reconnect and re-login in those cases.
• Wait at least two minutes after pressing Start. Do not assume the
upload did not work. The upload could simply be slow.
• Each distributed file upgrades a different component of the system. Be
sure to apply all files provided as part of an upgrade. The system
knows what to do with each file you give it, and they are checked for
validity before being applied.
Purchase Options

The VNC Interface
There are three ways to communicate with the SVxx54DX4I unit in order
to control the host computer:
• Web interface: The integrated Web server includes a Java-based VNC
client. This allows easy browser-based remote control.
• Cleartext VNC: There are several third-party software programs that
use the standard VNC protocol, available in open source and
commercial VNC clients. By pointing any VNC client at the default
VNC port (5900) on SVxx54DX4I, you will be able to control the
attached systems. This method offers a fast and direct way to access
the system and allows the use of“native”VNC clients and other remote
management packages which implement the VNC protocol.
• SSH access: By default, there is a standard SSH server running on
port 22 (the standard SSH port). Once connected via SSH, VNC traffic
may be tunneled to port 5900 on localhost (ie. 127.0.0.1:5900) of the
SVxx54DX4I.
• AnyVNC client may be used to access most features. Encryption does
not affect VNC operation, aside from a slight reduction in speed.

Native VNC Client
This system implements the VNC protocol, so any off-the-shelf VNC
client can be used. There are several different VNC clients available and
they should all work with this system. This system automatically detects
and makes use of certain extensions to the basic RFB protocol that is
provided by some of the the better VNC clients.
available for Windows, Linux, MacOS and many versions of Unix. Source
code for all clients is available there too. This version of VNC is being
actively developed. The authoritative version of VNC is available from
of VNC, maintained by the original developers of the standard. For a
commercial, supported version of VNC, you should consider TridiaVNC
and contains a number of enhancements for use in a larger corporate
environment.
SSH Tunnel (with Native VNC client)
If you are using openssh, here is the appropriate Unix command to use,
based on the default settings on a machine at 10.0.0.34 ssh -f -l admin -L
15900:127.0.0.1:5900 10.0.0.34 sleep 60 vncviewer 127.0.0.1::15900
Same command, but using the WAN port: ssh -f -l admin -L
15900:127.0.0.1:5900 10.0.0.98 sleep 60 vncviewer 127.0.0.1::15900
Notes:
• A copy of these commands, with appropriate values filled in for your
current system setting, is provided in the on-line help page.This allows
you to “cut-and-paste” the required commands accordingly.
• You have 60 seconds to type the second command before the SSH
connection will be terminated.
• The port number “15900” is arbitrary in the above example and can
be any number (1025...65535).It is the port number used on your client
machine to connect your local SSH instance with the VNC client. If
31
Download from Www.Somanuals.com. All Manuals Search And Download.
you want to tunnel two or more systems, you will need to use a unique
number for each instance on the same SSH client machine.
• Some Unix versions of the VNC client have integrated SSH tunneling
support. Some clients require your local user id to be the same as the
userid on the system. Use a command like this:
vncviewer -tunnel 10.0.0.34:22
Using the VNC Menu
One of the unique features of this product is the VNC menu system.
Whenever you see a window with a dark blue background and grey
edges, this window has been inserted into the VNC data stream so that
it is effectively laid over the existing video. These menus allow you to
control the many features of the SVxx54DX4I without using the web
interface or a custom client. When you initially connect to the system,
a Welcome Window will appear, indicating which system you are
controlling, what encryption algorithm was used and what key strength
is currently in effect. Click anywhere inside the window to clear it, or wait
ten seconds.
Bribar Feature
Along the bottom of the VNC screen is a dark blue bar with various
buttons known as the bribar. Its purpose is to show a number of critical
status values and to provide shortcuts to commonly used features. Each
feature and its function is outlined below:
Kbd: This area will show either PS/2 (as in this example) or USB to
indicate if keyboard and mouse are being emulated via USB connection
or PS/2 signals. If Autosync appears beneath this indicator, the mouse
pointers on the local mouse and the VNC session will be synchronized
automatically.
Bandwidth: Indicates current average bandwidth coming out of
the Enterprise Class KVM unit. The second number measures
round trip time (RTT) of the connection when it was first established.
32

highlighting.If you choose Min/Avg/Max then you will override the default,
Auto. As the automatic mode measures actual network performance,
you may see the current mode switch from Min up to Avg or Max. The
different modes indicate more time spent on compression versus more
bandwidth. There is no visual difference between the modes, but there
can be a noticeable difference in speed and smoothness.
Mouse Resync
Resynchronizes the mouse pointer so that the local and remote mouse
pointers are on top of each other.
PS/2 Reset
Resets the PS/2 emulation going to the host and to the attached PS/2
devices. This can be used if the mouse stops responding or the PS/2

the host is not recognizing USB input devices, this button may be used
to restore functionality.
Take Control
When multiple users are connected to the same system, use this button
to take control away from another user. Only one user may control the
keyboard and mouse at any time. All users see the same picture. Please
note: It is important that multiple users not be connected to the same
physical network.

Video Tuning Menu
Use the Auto Everything button to automatically fine-tune all three
adjustments. If the test pattern for Color Offset calibration is not present
on the screen, then the Color Offset adjustment is skipped.
Changes/frame
Indicates the number of 16x16 blocks of video that are being sent, on
average, for every frame of video. With a static image being displayed by
the server, this number will be zero (shown as -nil-). Moving the mouse,
for example, will cause the number to jump to about 2 or 3.You may use
this number to judge the picture quality as you adjust the controls on
this menu.
Picture Positioning
Affects the image position on your screen. If you see a black line on
either side of your screen, or at the top or bottom, you can use the
arrow buttons to shift the image in that direction. Pressing Auto does
the same thing for you automatically. Use Save to save the changes you
have made manually. Since this adjustment depends on the video mode,
separate values are stored for each video mode.
39
Download from Www.Somanuals.com. All Manuals Search And Download.
Color Offset
Color Offset is a fine tuning adjustment that requires the use of a
test pattern. There is a copy of the test pattern available on the Help!
menu of the integrated web server. You must arrange for that image
to be shown on the host computer. Do not allow scaling, cropping or
any other changes to that image. Press the Auto button and the system
will calibrate color for the best possible picture in approximately one
minute. If the system cannot find the test pattern on the screen, it will
say so. Check that the pattern isn’t scaled or covered up. It’s important to
perform this operation in 24-bit or 32-bit color video mode (i.e. truecolor).
Although the algorithm may work in 16-bit or 8-bit color video modes,
the results will not be optimum and usually it won’t be able to recognize
the test pattern.
Advanced
Pressing this button will open the Advanced Video Tuning menu. While
the vast majority of users will not need to adjust these settings, it offers
added control of the video settings of your VNC sessions.
Sampling Phase
Does not normally need to be used, since SVxx54DX4I tunes
the sampling phase whenever the video mode changes. This
button does not require a test pattern, but will perform optimally
when used with our standard test pattern. For your reference, the
sampling phase number is shown to the right of the Filtering button.
Noise Filter
Controls the advanced video filtering of the SVxx54DX4I. Unlike other
filtering algorithms, the SVxx54DX4I noise filter will only remove noise
- it does not degrade the signal quality or readability of small text. You
may turn it on and off using the indicated button, or set it to other values
using the arrows.
Higher numbers cause more filtering and may cause artifacts when
moving windows. The most common visual artifact is a vertical line
40
Download from Www.Somanuals.com. All Manuals Search And Download.
dropping when moving windows horizontally. You may use the Redraw
button to correct these, or use a lower filter number. At minimum, these
values must be greater than two.
Flatness Filter
To improve compression ratios, the SVxx54DX4I will group adjacent
pixels that are nearly the same colour and treat them as equal. This
helps to compress typical simple GUI images. However, the effect of this
compression on continuous-tone images and gradients can be annoying.
You may turn off or reduce the flatness filter to sacrifice bandwidth for
improved image quality in those areas.
Please note that at higher values, some parts of the screen may appear
“blocky”.
Getting Peak Video Performance
Choose the best video mode
• We recommend using 60Hz refresh rate and 1280 x 1024 resolution.
Using a smaller resolution like this allows you to fit multiple windows on
your remote desktop. Higher refresh rates stress the video card’s
quality and do not provide any additional information or benefit.
Noisy video cards
• A digital KVM works by converting the analog video signals emitted
by your video card into digital data. If there is noise on that signal, then
it must also be digitized and sent over the network.Quality video cards,
in our experience, offer better performance simply because they don’t
add analog noise.
• Some external KVM switches generate video noise as well.Try to keep
cables short, in order to reduce this effect.
•
Enable the Noise Filter option (on the Video Tuning menu) to mitigate
noise issues.
Network performance
• SVxx54DX4I will always send as much data as it can, given what’s
happening on the screen and the actual network performance. When
nothing is changing on the video screen, zero bytes are sent over the
41
Download from Www.Somanuals.com. All Manuals Search And Download.
network. If the whole screen is changing, then the unit will send as
much data as your network connection and VNC client allow.
• Network latency, which is the total time it takes for a packet to get to
the SVxx54DX4I and come back, has the biggest impact on perceived
performance and usability. Network bandwidth has a lesser effect,
particularly when just moving the mouse around.
• Only a few bytes need to be sent when the mouse is moving (and
nothing else is changing on the screen), but the round-trip-time limits
the hand-eye coordination of the user if it is too great.
• Both actual bandwidth and measured network latency are shown in the
Main Menu.
Using the Advanced Video Tuning Feature
The Advanced Video Tuning menu allows you to adjust the qualities of
the video in your VNC sessions, and can be accessed by clicking the
Advanced button on the Video Tuning VNC menu. While many users
will probably allow the SVxx54DX4I to automatically configure the video
properties, you can use this menu to exercise a great deal of control over
the settings if you wish.
The Presets section contains up to sixteen different settings, plus the
factory setting. If a number is highlighted, then that preset has been
programmed with valid settings and may be used. Note that the Factory
preset is always available. Simply click on the appropriate button and
the default settings will be restored. To save settings to a preset, click
on the Save->Preset button in the Actions pane. The preset buttons will
highlight. Click the desired preset button to save the values. Note that
any previous settings assigned to that button will be lost. If you do not
wish to save the presets after clicking the Save->Preset button, click
the Save->Preset button a second time and the save function will be
cancelled.
The section of the screen marked Current Values indicates the various
video parameters that can be adjusted. For each parameter, there are
a series of buttons: [, <<, -, Auto, +, >, ]. The [, and ] buttons set the
parameter to its smallest or largest values, respectively. The << and >>
42
Download from Www.Somanuals.com. All Manuals Search And Download.
buttons decrease or increase the parameter by a large amount. In the
case of phase, this is four units and for all others, ten units. The - and
+ buttons decrease or increase the parameter by one unit. The middle
button sets the parameter to the middle value. The text of the middle
button also indicates which parameter is being controlled. Note that in
the case of phase, the middle button invokes the auto-phase algorithm.
The Performance section of the screen indicates the quality of the video.
Changes/frame is the average number of tiles that change for each frame
sampled by the hardware. Flatness is an indication of what percentage
of the screen contains tiles that are comprised of only one color.
The Regrab Screen button in the Actions section causes the screen to
be re-captured. When making small changes to the video parameters,
sometimes these changes are not reflected in the displayed screen
immediately, particularly if the noise filter is enabled. Press this button to
see the immediate effect of the changes.
Use the Show Diffs button to learn which parts of the screen are being
sent over the Internet.When you click this button, the screen is cleared to
a medium grey color. All blocks that are sent from that point on will show
up on the screen as they are sent. Click the button again to reset the
screen to grey. To return to normal operation, click the Regrab button. It
is very easy to visually identify the effect noise has on signal processing,
using this feature.
The Auto Offset & Gain button in the Actions section invokes the
automatic algorithm for setting the video parameters. The algorithm
requires the factory calibration test pattern to be correctly displayed on
the screen.

time. It is safe to hot plug USB devices, but PS/2 systems will typically
require a power cycle.
Please Note: After changing your configuration, the OSD will
automatically update to reflect the new configuration.

Using the Modem feature
NOTE: Requires an RJ45 to DB9 adapter. Please see StarTech.com
part number(s): GC98FF (DB9 Female to RJ45 Female Adapter) or
GC98MF (DB9 Male to RJ45 Female) as applicable.
Background
The modem feature allows the SVxx54DX4I to act as an Internet
connection server for increased security and flexibility in connecting with
the host computer.
Unlike the TCP/IP connection used with the standard Web configuration
and VNC clients, the modem creates a one-to-one connection between
the SVxx54DX4I and the computer you are using to manage the host
computer that is essentially private, as it bypasses the public Internet
completely.
Please note that this feature requires both an external modem (most
standard connection protocols are supported) and a dedicated phone
line that can be connected to the modem for external access. While
it is possible to use the modem feature through some PBX systems,
this increases the complexity and reduces the performance of the
connection. For clarity, the instructions presented here assume that the
modem is connected to a typical POTS (plain old telephone system)
line that is not routed through a phone management system or shared
with other devices. If you wish to use this feature through a PBX system,
it may require some experimentation and additional support from your
telecom services provider, and is not supported by StarTech.com.

Connecting a Modem
The SVxx54DX4I will work with virtually any Hayes-compatible
modem that recognizes the standard AT command set. Some modem
manufacturers offer “enterprise” grade modem products that include
technology to improve the stability of connections; whether this type
of product would be beneficial to your application depends on whether
you consider the modem connection to be mission-critical, the quality
of your telecom infrastructure, and your budget for implementing this
solution. The model of modem attached is essentially transparent to the
SVxx54DX4I.
It is important to note that modems that offer “56K” (or 56,000 bps)
connections often achieve connection speeds that are far lower than
their maximum capabilities.Given the limitations of telecom infrastructure
(many locations have yet to implement fully digital switching technology,
and still rely on older analog technology for some segments), the
maximum “upstream” transfer rate is limited to a maximum of 33,600 bps
between two modems; the “downstream” rate is often within a similar
range for a typical connection. Therefore, speeds below 56,000 bps do
not indicate a problem with the modem or the SVxx54DX4I, but simply
48

reflect the line conditions at the time the connection is made.
The serial port can be used for serial port configuration when the modem
is connected. It requires the use of a null modem serial cable.
1. Place the modem near the SVxx54DX4I and an available telephone
jack. Connect the modem to the telephone jack, data cable, and power
source according to the instructions in its documentation.The opposite
end of the modem’s data cable should be a DB9 female serial
connection.
2. Connect that end of the cable to the Serial connection on the rear
panel of the SVxx54DX4I.
Modem configuration
Although most connections will work appropriately with the default
settings on SVxx54DX4I, manual changes can be made. To do so:
1. Login to the Web interface as Admin.
2. Click Modem, listed on the left side of the main page.
3. You will then be presented with the Modem Option menu.
4. Make the following changes to enable and configure the modem
connection:
• Enable modem connections (PPP) via serial port/modem: select
Enabled.
• Baud rate to use (affects connection between us and the modem
only): select 115200.
• Init string: leave as ATE0S0=1&K3 (see below).
The baud rate dictates the connection speed between the SVxx54DX4I’s
serial port and the modem, and does not affect the connection speed
between the local and remote modems, as they will negotiate their own
connection speed when a connection is made. It is highly recommended
that this setting be left at the default for best performance.
The initialization (“init”) string is the command (using the standardized
Hayes AT command set) that the SVxx54DX4I will send to the modem
49
Download from Www.Somanuals.com. All Manuals Search And Download.
to activate it. The string included should work with the majority of
modems and configures the following connection properties: answer
incoming calls on the first ring, enable hardware flow control, and lock
the connection speed.
Your modem’s documentation will describe other potential init strings that
you can use to alter the connection properties. For instance, you could
commit the settings to the modem’s non-volatile memory (NVRAM) or
allow the modem to adjust the connection speed for greater stability
(and so on). You may wish to test the connection with the default init
string first, before making changes specific to your modem model or
situation, to simplify the troubleshooting process.
5. Click the Commit button to save your changes and activate the modem
feature with the specified settings.
Configuring the Remote Connection
This section describes how to configure a typical Windows dial-up
session to access the modem connection on the SVxx54DX4I. The
instructions here relate to a Windows XP configuration; other versions of
Windows are similar, if not identical.
Please note the following:
• PPP (Point-to-Point Protocol) must be used; no other authentication
methods are supported.
• TCP/IP must be installed/enabled on the computer making the
connection, and must be used for the dial-up connection.
• The connection must be configured to obtain a dynamic IP address.
• The user name/password must match a user currently configured on
the SVxx54DX4I.
• For best performance and to simplify the troubleshooting process,
firewall software should not be used with the dial-up connection.
1. Open My Network Places from the desktop or the Start menu.
2. Click View network connections.
50
Download from Www.Somanuals.com. All Manuals Search And Download.
3. Click Create a new connection under Network Tasks.
4. The New Connection Wizard window will open. Click Next.
5. Select Connect to the Internet, then click Next.
6. Select Set up my connection manually, then click Next.
7. Select Connect using a dial-up modem and click Next.
8. In the space provided under ISP Name, type an appropriate name of
your choosing for the connection, then click Next.
9. In the space provided under Phone Number enter the phone number
for the line to which the SVxx54DX4I’s modem is connected.You may
need to add the area code, country code, or other digits needed to
access the outside line as appropriate. When finished, click Next.
10. Make your choice from Anyone’s use or My use only and click
Next.
11. Beside User name, enter the user name of any valid user created
using the Web interface of the SVxx54DX4I. Beside Password and
Confirm password enter the password that the user you entered
above uses to access the Web interface.
12. This screen also includes three checkboxes
-
remove all
checkmarks, then click Next.
13. You may select to add a shortcut to the desktop for this
connection.
14. Click Finish.
Accessing the Web Interface
Once a dial-up connection has been established, you can access the
Web interface or start a VNC session using the following IP address:
You can now login to the Web interface (and/or VNC session) normally.
Note that the remote machine (the one from which you dialed) is
automatically assigned the IP address 99.99.99.100 for the PPP session.
51
Download from Www.Somanuals.com. All Manuals Search And Download.
This, and the IP address of the SVxx54DX4I, cannot be modified. The
following TCP/IP port numbers are assigned for a PPP connection,
regardless of the settings configured in the Web interface for the LAN
or WAN ports:
HTTPS: 443
VNC (clear-text): 5900
VNC (SSL secured): 15900
SSH: 22
Performance Notes
• All images over the PPP connection will be grayscale to conserve
bandwidth. If other users are connected while a PPP session is active,
their screens will be in grayscale as well.When PPP is inactive, color is
automatically re-enabled.
• Some areas of the screen may not be updated as frequently as others,
and animations or other auto-updating areas of the screen may appear
out-of-focus or “blocky” as a result. Since the area around the mouse
pointer is refreshed most frequently, hold the pointer over an area to
improve its clarity.
• It may be beneficial to minimize any unnecessary icons, backgrounds,
or other clutter on the host computer’s desktop to make the dial-up
connection as efficient as possible.
If you need to configure the device over a serial connection while the
modem option is enabled, connect a serial cable and begin a terminal
session following the instructions under the section titled Terminal
Configuration Using a Serial Cable in this manual. Once connected, you
will see the following message:
Expecting a modem,if human, type admin password (Or start
PPP)
Type the password for user admin and press Enter. The password will
not appear on the screen. The configuration menu will appear. Make the
changes you wish or press q and Enter to exit and leave the modem
connection active.

parties called Certificate Authorities (CAs) and contain essential details
aboutasitethatmustmatchtheinformationsuppliedtoyourWebbrowser.
Why do I receive a warning when accessing the login screen?
As it redirects you to a secure (SSL) session by default, the login screen
may generate a warning from your Web browser or the VNC Java client
for two different reasons. First, the CA that has issued the certificate on
StarTech.com’s behalf may not yet be recognized as a trusted source by
the computer you are using to access the SVxx54DX4I. Second, since
the unit could be configured in a number different ways, it is impossible to
supply a generic certificate that will match your exact network settings.
Is my data safe?
Yes.Thesecuritycertificatedoesnotaffectencryptioneffectivenessinany
way,nordoesitmaketheSVxx54DX4Ianymorevulnerabletooutsideattacks.
Can I prevent the warning from occurring?
Yes.You have two options that may prevent the warning from occurring.
First, if the Web browser you are using offers the option to ignore the
warning for future visits, the browser will no longer generate a warning
if that option is selected. Second, if you install the certificate from the
SVxx54DX4I onto the host computer (see below) and if the unit is
configured with a domain name ending in .com, .net, .org, .gov, .edu, .us,
.ca, .uk, .jp, or .tw (i.e. remotecontrol.mydomain.net) then the warning
should no longer occur.
Installing the new certificate
The following instructions detail how to install the certificate from the
SVxx54DX4I onto your local computer (in this case, when using Internet
Explorer with Windows XP):

Troubleshooting
Forgotten master password
You can reset the master password using the serial interface on the unit.
Use the S command, and type a new password.The old password is not
required for this procedure.
Similarly, you can press (and hold) the reset button (located to the
immediate left of the USB ports on the rear panel) for thirty seconds to
clear all settings and return the unit to factory defaults. This will clear the
password to be admin.
Using a PS/2 Mouse, the remote mouse pointer and local mouse
pointer don’t line up
Use the Mouse resync command in the main menu or press the Resync
button on the Bribar. If the mouse pointers still don’t line up, verify that
mouse acceleration has been disabled.
Please note: The Windows login screen does not accept the “mouse
acceleration” configuration, and always has the mouse accelerated
regardless of your configuration. Therefore, on this screen it is best to
avoid using the mouse.
After resync, the mouse pointers are still not aligned.
Use the video adjust menu to position your video image exactly where
it should be. Normally a slight video positioning error is perceived as
a mouse sync issue. A video positioning error is visible as a black line
along the top or bottom (and right or left) edges of the remote screen.
Remember to save your position changes!
Cannot login via SSH.
Remember to use either admin or a username created in the system
as the user name you give your SSH client. If you see a warning about
identity of host cannot be verified, and a question about saving the host’s
fingerprint, this is normal for the first time you connect to any machine
running SSH. You should answer yes so that your SSH client saves the
