2. Ins tallation  
2.1 What you will need  
Cables to connect the AdderView GEM to each of your PC keyboard, video and  
mouse ports. Cable specifications are given in appendix A. (You do not need to  
connect a mouse cable if you are not using the mouse).  
A monitor with a standard VGA/SVGA (15 pin) connector that will work when  
connected directly to each of your PCs. AdderView GEM supports low and high  
resolution monitors.  
A standard AT or PS/2 style keyboard. If you are using an AT keyboard with a 5  
pin connector you may connect this to the AdderView GEM using a standard AT to  
PS/2 keyboard adapter.  
A PS/2 style two or three button Microsoft or Logitech compatible mouse or a  
Microsoft IntelliMouse / IntelliMouse Explorer compatible mouse. If you wish to use  
the mouse to switch the AdderView GEM's channel then you will need a three button  
mouse or an IntelliMouse.  
(The AdderView GEM supports Internet Mice’ that are compatible with the Microsoft  
IntelliMouse. These are fitted with a wheel or other scroll control and sometimes  
have additional buttons. Examples are: Microsoft IntelliMouse, Logitech Pilot  
Mouse+, Logitech MouseMan+, Genius NetMouse and Genius NetMouse Pro.)  
A suitable mouse driver for your PCs. Supported types are:  
- PS/2 or RS232 two button mouse driver (any manufacturer).  
- Microsoft mouse driver (including IntelliMouse).  
- Logitech mouse driver (including two button, three button and wheel mouse)  
Us e of PS/2 and RS232 s tyle mice with the AdderView GEM - All of the mouse  
connections from AdderView GEM to PCs support either a PS/2 or an RS232  
mouse. AdderView GEM automatically converts from the PS/2 mouse commands to  
RS232 serial mouse commands. Serial mice types are selected by using an adapter  
as described in Appendix A. The AdderView GEM will operate without a mouse  
connected if you do not wish to use one.

2.2 Mounting the AdderView GEM  
The AdderView GEM has been designed for use on a desktop or shelf in close  
proximity to the users monitor and peripherals. The optional remote controller may  
be used if you wish to locate the AdderView GEM on a desk or shelf that is some  
distance from the monitor and peripherals.  
2.3 Connecting your devices  
Ensure that the optional power adapter is disconnected from the AdderView GEM  
and that all the devices which are to be attached are switched off. Connect the  
shared keyboard, PS/2 mouse and monitor to the connectors at the rear of the  
AdderView GEM (see figs 1, 2 and 3). Next, connect each computer system unit in  
turn with the keyboard cable, mouse cable and video cable. Adder 3-in-1  
keyboard/video/mouse cables are recommended for maximum convenience. Any  
unused computer connections can be left unconnected. To connect computers with  
serial mouse connections and AT style keyboard connections use the adapters  
specified in appendix A. If you have an existing 6-pin mini-DIN to 9-pin serial adapter  
that came with a mouse it may not be suitable for use with the AdderView as there  
are several different standard wiring configurations for these adapters.  
The AdderView GEM is now ready for use and will start to operate as soon as one of  
the attached PCs is powered on. If you are connecting to PCs using cables that are  
longer than 5 metres or are cascading the AdderView GEM to another AdderView  
GEM you will need to use the optional power adapter. When using the optional  
power adapter, ensure that it is connected to the mains and powering the AdderView  
GEM before you switch on the connected computers. Failure to switch the  
AdderView GEM and computers on in the correct order can lead to the mouse  
and/or keyboard not being recognised by the computers when they are switched on.

2.4 Interface powered’ operation without the optional power  
adapter  
The AdderView GEM draws its power from the connected computers via the  
keyboard cables. A single keyboard connection is normally sufficient to power the  
AdderView GEM provided that the cable is no longer than 5 metres. If more than  
one computer is connected then the power will be intelligently drawn from all  
computers. Cables longer than 5 metres may be used provided that the AdderView  
GEM is already powered by another connected computer or the optional power  
adapter. If you are cascading the AdderView GEM to another AdderView GEM then  
a power adapter must be connected to all AdderView GEMs.  
2.5 Configuring your PCs  
Configure your PC in the same way that you would if your keyboard, mouse and  
monitor were all connected directly to your PC. AdderView GEM emulates Microsoft  
compatible serial, IntelliMouse, IntelliMouse Explorer and PS/2 mice, so ensure that  
your PC software is configured for a Microsoft mouse of the correct type. Refer to  
the list of supported drivers in section 2.1.  
2.6 Configuring the AdderView GEM  
The AdderView GEM is supplied pre-configured with factory defaults which are  
suitable for most applications. There are a number of more advanced options which  
can be set by the user. These are stored in the AdderView GEM's EEPROM  
memory and are retained when the power is disconnected.  
The options may be changed whilst the AdderView GEM is in configure mode. You  
may enter configure mode at initial power on or whilst the AdderView GEM is  
running:  
AdderView GEM

To enter configure mode at power on:  
Switch off all the attached PCs and the AdderView GEM. Hold down the front panel  
key whilst powering on the AdderView GEM. Remember that the AdderView GEM  
draws its power from any attached PC via the keyboard cable and so will power itself  
on when the attached PC is switched on or when the optional power adapter is  
connected. Do not release the key until the AdderView GEM displays 'C' to show  
that it has entered configure mode.  
To enter configure mode whils t the AdderView GEM is running:  
Hold down the front panel key for 5 seconds until the front panel display shows C.  
In configure mode, options are entered by typing a letter followed by a number  
followed by (return). Use ESC to abort the entry of an option. The AdderView GEM  
will remain in configure mode until you type 'E' (return).  
For example: to set hotkey option 2 type the following at the 'C' prompt  
(at AdderView GEM 'C' prompt)

2.8 Res etting the AdderView GEM without dis connecting your  
devices  
The AdderView GEM draws its power from the connected computers and therefore  
may only be fully powered down when all the connected computers have been  
switched off or disconnected. However, the AdderView GEM may be reset without  
disconnecting or powering down your computers by using the reset switch on the  
underside of the unit. Performing a reset using this switch performs a complete  
hardware reset on the AdderView GEM and is equivalent to switching off the power.  
To perform a hardware reset, move option switch 8 to the ON position (halt and  
reset) and then back to the OFF position (normal operation).

2.9 Other us eful ins tallation information  
PC boot up s equence - When your PCs are powered on they communicate with  
any attached keyboards and mice and setup parameters required by the particular  
operating system. It is necessary for the AdderView GEM to be attached and  
powered on during this sequence so that it can give the required responses and  
keep track of all the modes and settings requested by each of the connected PCs.  
Mous e characteris tics - do not unplug a PS/2 mouse connection from a PC whilst  
the PC is on. Due to the design of PS/2 mice communications the mouse function on  
the PC will be lost and you will have to re-boot the PC to regain normal operation.  
Unplugging the mouse from the AdderView GEM will also cause it to stop operating  
when it is plugged back in. RS232 mice can usually be unplugged and plugged back  
in provided that a mouse was connected when the operating system initially booted.  
The AdderView GEM is fitted with a PS/2 mouse recovery system which allows you  
to disconnect and re-connect the shared mouse without powering down the system  
(although this is generally not advisable) - see section 2.10 for details.  
Keyboard and mous e mode s witching - The AdderView GEM keeps a log of the  
keyboard and mouse mode and resolution settings requested by each of the  
connected PCs. These settings are automatically restored to the shared keyboard  
and mouse when the AdderView GEM channel is switched thus ensuring maximum  
software compatibility. The keyboard num, caps and scroll lock states are an  
obvious example of this process.  
2.10 Re-enabling a dis connected PS/2 mous e  
If you disconnect the shared PS/2 mouse from the AdderView GEM by accident  
during operation then the mouse operation will be lost when the mouse is plugged  
back in. To avoid having to reboot the entire system in this situation the AdderView  
GEM is fitted with an automatic mouse recovery system.  
With the PS/2 mouse disconnected, change the channel using the keypad or  
keyboard hotkeys. The AdderView GEM detects that the mouse has been  
disconnected and triggers the automatic recovery system. Plug in the PS/2 mouse  
and the AdderView GEM will re-initialise it.  
AdderView GEM  
Ins tallation and Us e

Alternatively you can reset the keyboards and mice by holding down the front panel  
key for 5 seconds. When the character Cis displayed on the front of the AdderView  
GEM, press the front panel key again. A complete power off reset of the connected  
keyboards and mice will then be performed. This function only resets the shared  
keyboard and mice that are plugged into the control port. It does not affect the status  
of any of the other ports on the switch or the CPU connections.  
2.11 Hot plugging the AdderView GEM into running s ys tems and re-  
enabling dis connected CPU PS/2 mous e connections  
It is advisable to switch off the systems that are going to be connected to the  
AdderView GEM before installation. However, if this is not possible then most  
systems can be hot plugged by using the AdderView GEM’s mouse restoration  
functions. The keyboard connection will normally restore itself automatically.  
On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and  
plugged back in whilst the PC is running. Mouse movement can then only be  
restored by rebooting the PC. This is because the mouse drivers only setup and  
enable the mouse when the PC is initially booted.  
If you have switched off your AdderView GEM or you are attempting to hot plug’ it  
into a system that is already running, you may be able to restore lost mouse  
movement using the AdderView GEM's mouse restoration functions.  
Mous e res toration functions s hould be us ed with care as unpredictable res ults  
may occur if the wrong mous e type is s elected. If in doubt res tore the mous e  
by powering down the PC normally.  
Standard PS/2 mouse data uses a different data format to IntelliMouse data and so  
two reset functions are provided on the AdderView GEM. The type of data format  
expected by the PC depends upon the driver and the type of mouse that was  
connected when the driver was booted. The following table may be used as a guide.  
Note that the mouse reset functions predict the likely mouse resolution settings but  
may not restore the speed or sensitivity of the mouse exactly as they were when the  
PC originally booted.

2.12 Upgrading the AdderView's flas h memory  
The AdderView GEM uses flash memory technology which enables the firmware  
code to be upgraded by the user. Upgrades are performed by connecting a PC's  
serial port to the AdderView's options port and running an upgrade program on the  
PC. This upgrade program downloads the new firmware to the AdderView and  
checks that the data has been programmed correctly.  
AdderView GEM  
Ins tallation and Us e  
Page 17  
Download from Www.Somanuals.com. All Manuals Search And Download.  
To perform a firmware upgrade on your AdderView GEM you will need a suitable  
serial upgrade cable and an IBM PC compatible computer with an RS232 serial port  
and an operating system that supports DOS. Upgrade cables may be purchased for  
Adder Technology or may be made using the wiring specification given in Appendix  
A4. You will also need to download the latest version of the AdderView GEM  
firmware which is available free of charge at www.addertec.com.  
To perform a flash upgrade on the AdderView GEM:  
Step 1 - Connect your computer to the AdderView  
Connect your computer's serial port to the AdderView GEM's options port (labelled  
OPTIONS/FLASH).  
Step 2 - Select flas h upgrade mode us ing option s witch 7  
Move option switch 7 on the underside of the AdderView GEM to the ON position.  
Step 3 - Res et the AdderView GEM  
Reset the AdderView GEM by moving option switch 8 to the ON position (halt and  
reset) and then back to the OFF position (normal operation). Alternatively you may  
reset the AdderView by powering off all the attached computers and removing the  
optional power adapter.  
Step 4 - Ens ure that the AdderView is powered on  
Ensure that the AdderView is powered on. It is normally possible to upgrade the  
AdderView when it is powered from a single computer, however it is good practice to  
ensure that there is the maximum possible power availability during flash upgrades  
and so if possible ensure that all the computers are powered on. The upgrade  
program monitors the AdderView's voltage and will not allow an upgrade to be  
performed if the voltage is insufficient.  
The display should now show:  
AdderView GEM  
Ins tallation and Us e  
Page 18  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Step 5 - Run the upgrade program  
The latest version of the AdderView GEM firmware is available from the Adder  
Technology website at www.addertec.com. The program and data files are  
supplied as a pair e.g.  
AVG129.EXE  
AVG129.HEX  
and should be downloaded to the same directory on your PC. Run the file  
AVGxxx.EXE (e.g. AVG129.EXE) and follow the on-screen instructions. During the  
upgrade the display will show an upper case U and the dot will flash to show that the  
upgrade is in progress.  
The display will again show a lower case U when the download is complete. Move  
option switch 7 to the OFF position to exit upgrade mode and start normal operation.  
You may check the new firmware version by entering configure mode and using the  
firmware version query function.  
Some us eful is s ues to bear in mind when performing flas h upgrades  
The upgrade program rewrites the AdderView's firmware code. If the upgrade  
process is interrupted then the AdderView will have invalid code and will not be able  
to operate. It is therefore good practice to ensure that the upgrade process is always  
fully completed. A partial or failed upgrade may be rectified by performing another  
upgrade. If the upgrade process is interrupted accidentally then you should  
immediately repeat the upgrade process without moving switch 7 from the flash  
upgrade (ON) position. Switch 7 forces the AdderView into flash upgrade mode and  
prevents the upgraded code from being run. Running faulty or partially upgraded  
code may have unpredictable results and may damage your AdderView or  
computing equipment. For obvious reasons, the code that the AdderView uses to  
perform upgrades is not itself upgradeable - a common problem on some flash  
upgradeable products that could effectively be destroyed by a partial upgrade!  
WARNING - Running faulty or partially upgraded code may have unpredictable  
res ults and may damage your AdderView or computing equipment.

3. Us ing the AdderView GEM  
This section explains the general operation of the AdderView GEM. We recommend  
that you read this section before starting to use the product.  
3.1 Power on s tatus  
At power on the AdderView GEM selects computer 1 and displays '1'. If a password  
has been set then P will be displayed and the AdderView GEM will remain locked  
until a valid password is entered.  
3.2 Front panel key and remote controller  
The front panel key is used to select which channel is currently controlled by the  
shared keyboard, mouse and monitor ports. Pressing the key during normal  
operation will cause the next channel to be selected.  
The key can also be used to access the AdderView GEM’s configuration mode (see  
section 2.6). To do this press the key and hold it down for 5 seconds until ‘C’  
appears on the AdderView GEM’s front panel display.  
An optional remote controller is also available which replicates the front panel key  
and display, but can be located remotely from the AdderView GEM. This is  
AdderView GEM  
Ins tallation and Us e

Download from Www.Somanuals.com. All Manuals Search And Download.  
particularly useful in applications where the AdderView GEM is located away from  
the desktop. The remote controller can be conveniently attached to your keyboard  
with a couple of Velcro strips to give instant channel information and key control.  
3.3 Status dis play  
The status display usually shows the currently selected port. If autoscan mode is  
selected, the segments will illuminate in sequence in a clockwise direction  
interspersed with a display of the currently selected channel. If AdderView GEM has  
been locked, P will be displayed until a valid password has been typed to unlock  
the unit. Data flow from the mouse or keyboard causes the dot to flash.

3.4 Keyboard hotkey control  
AdderView GEM can be conveniently controlled by selecting channel, autoscan  
mode or security locking from the keyboard. All of the hotkey control commands are  
invoked by holding down the two hotkeys and then pressing a command key. By  
default, the two hotkeys are CTRL and ALT’, although other combinations can be  
selected by reconfiguring the hotkeys (see section 4.4). Once the hotkey command  
has been activated you will need to release the hotkeys and the command key  
before a new hotkey command is accepted by the AdderView GEM. HOTKEYs +  
TAB is an exception and this allows you to 'tab through' the ports by holding down  
the hotkeys and repeatedly pressing TAB.  
The hotkey command are summarised below (note that the numbers on the numeric  
keypad do not form part of a valid hotkey) :  
‘HOTKEYs ’ and 1- selects channel 1  
‘HOTKEYs ’ and 2- selects channel 2  
‘HOTKEYs ’ and 3- selects channel 3  
‘HOTKEYs ’ and 4- selects channel 4  
‘HOTKEYs ’ and TAB’ - selects the next channel  
‘HOTKEYs ’ and A’ - selects autoscan mode where each channel is displayed for  
the selected time (see section 4.2). To cancel autoscan mode simply select any  
fixed channel either by hotkey or using the AdderView GEM button.  
‘HOTKEYs ’ and 0switches off the video signal and displays 0. This will cause  
some monitors to go into standby mode or switch off. The video signal can be re-  
enabled by selecting a channel.  
‘HOTKEYs ’ and L’ - disables the AdderView GEM's keyboard and mouse and  
displays 0. The video signal is switched off. If a password has not been set then the  
AdderView GEM can be re-enabled by selecting a channel. If a password has been  
set then the AdderView GEM displays 'P' to indicate that a valid password must be  
entered to unlock the switch. Simply type the same key combination as was set  
during configuration (see section 4.7) followed by the (return) key. Note - if anyone  
has typed at the keyboard whilst in secure mode, it will be necessary to type (return)  
first to clear the invalid password, then type the valid password followed by (return)  
again.

To s elect channel 2:  
press ba2release 2ba  
To 'tab through' channels :  
press bavrelease vpress v

3.5 Mous e control  
Computers may conveniently be selected using a three button mouse. In order to  
switch to the next computer simply hold down the central mouse button (the wheel  
mouse button on an IntelliMouse) and click on the left hand mouse button to select  
the next computer or the right hand mouse button to select the previous computer. If  
the AdderView has been set to scan active ports then the next or previous active  
channel will be selected. If it has been set to scan all ports then the next or previous  
numerical channel in sequence will be selected (see section 4.5 for more details).  
Mouse switching may be enabled or disabled by setting options during configuration  
(see section 4.3). When mouse switching is disabled the third button or wheel button  
state is ‘passed through’ the AdderView and seen by the application software.

3.6 RS232 control  
AdderView GEM can be controlled by a remote RS232 device. To select a channel  
the data rate of the sending device must be set to 1200 baud, 8 bits, no parity and 1  
stop bit. No handshaking is used by the AdderView GEM. Simply send the character  
for the channel which needs to be selected, for example ASCII ‘1 (hex code 31) will  
select channel 1, ASCII ‘2’ (hex code 32) will select channel 2 and so on. The  
AdderView will echo the ASCII character back to the sending device when the  
channel has been changed. The serial interface pins are found on the options  
connector on the rear of the AdderView. Pin assignments for this connector are  
given in appendix A.  
3.7 Cas cading AdderView GEMs  
AdderView GEM switches can be connected together to expand the number of  
connected computers. When cascading AdderView GEMs a power adapter  
(AVGPSU) must be connected to each AdderView GEM. AdderView GEMs can be  
connected in a cascaded tree structure. This can be particularly useful where  
clusters of computers are located some distance from each other because each unit  
acts as data booster and can each be up to 30 metres away from the next  
AdderView GEM. The channel can be selected on remote AdderView GEM units  
using an extension of the HOTKEY control .  
For example, consider a situation where two AdderView GEM units are connected  
together as shown below. To connect to the computer attached to port 3 on  
AdderView GEM B the user would hold down the hotkey keys then press 2 followed  
by 3, whilst keeping the hotkey keys pressed. This will have the effect of connecting  
to port 3’ of the AdderView GEM which is connected into port 2’ of the first  
AdderView GEM unit A.  
For example to connect to port 3 on the AdderView GEM cascaded off port 2 of your  
first AdderView GEM use:  
press ba  
2release

ba  
3
press 3release

3.8 Synchronis ing AdderView GEMs for multiple video head  
applications  
Multiple AdderViews may be connected together so that they operate in a  
synchronised manner. Synchronised 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. Such configurations are typically required in banking and  
engineering applications where greater video 'real estate' is required. Whenever the  
AdderView's channel is switched it sends an RS232 command out on its serial  
interface. The AdderView switches its channel if it receives the same command on  
AdderView GEM

its serial interface. Consequently, by linking the serial interfaces a master unit may  
be made to automatically switch a daisy chain of slaved units as shown in the  
diagram below. The slave units will require the optional power adapters because  
they cannot draw their power from the video link alone.

All the options described in this section are entered in AdderView GEM configure  
mode - see section 2.6 for instructions on entering configure mode.  
4.1 Screen s aver time delay  
AdderView GEM contains a programmable screen saver which will blank the display  
after the set time delay with no keyboard or mouse activity. Simply typing at the  
keyboard or moving the mouse will re-enable the display. The display will flash whilst  
the AdderView GEM is in screen save mode.  
B1 - screen saver disabled (default)  
B2 - Blank screen after 1 minute of inactivity  
B3 - Blank screen after 2 minutes of inactivity  
B4 - Blank screen after 4 minutes of inactivity  
B5 - Blank screen after 8 minutes of inactivity  
B6 - Blank screen after 12 minutes of inactivity  
B7 - Blank screen after 16 minutes of inactivity  
B8 - Blank screen after 20 minutes of inactivity  
4.2 Autos can lock on’ mode and delay time  
AdderView GEM can be set to select each channel in turn for a period of time set by  
the autoscan delay time. Autoscan mode is entered by typing the hotkey keys  
together with ‘A’. By default, only those channels which have a powered up  
computer connected to them will be scanned. Sometimes it may be desirable to  
scan all channels, even if the attached computer is switched off (this will simply  
show a blank screen when it is selected). All the AdderView GEM’s ports will be  
scanned if option L2 is selected. Some applications may also require the AdderView  
GEM to power on in autoscan mode. This feature can be selected using the L3 or L4  
options.

WARNING - Many modern monitors are fitted with automatic power s ave relays  
and will s witch off after a few s econds if connected to an inactive PC. If you  
are us ing s uch a monitor you mus t not us e the L2 feature. Cons tant s witching  
on and off of your monitor's relay will eventually damage your monitor.  
4.3 Mous e mode and mous e s witching of channels  
A three button PS/2 mouse or an IntelliMouse can be used to switch channels on the  
AdderView GEM. To switch to the next channel, the user simply holds down the  
central button or wheel button and presses the left or right hand button to change  
the channel (see section 3.5). If the user does not wish to take advantage of this  
feature, it can be disabled by selecting U2, U3 or U5. If the third button is being used  
to switch the AdderView GEM then it is not available for use with PC software  
although the function of an IntelliMouse wheel is not affected. Consequently in  
modes U1, U2 and U4 the AdderView GEM reports to the PCs that a 2 button  
mouse is connected. If you wish to use the full function of a 3 button mouse or  
IntelliMouse for your PC software then you should select options U3 or U5.  
The AdderView GEM supports Internet Mice’ that are compatible with the Microsoft  
IntelliMouse. These are fitted with a wheel or other scroll control and sometimes  
have additional buttons.

Standard PS/2 and IntelliMouse compatible mice can be connected to the control  
port. You may configure your CPUs using Microsoft PS/2 or IntelliMouse drivers in  
any combination as required. The IntelliMouse features are supported on both PS/2  
and RS232 CPU connections. When using PS/2 CPU connections, the AdderView  
GEM will automatically configure itself to the type of mouse requested by the driver.  
If you are using RS232 CPU connections then you will need to select mouse options  
U4 or U5 to enable the IntelliMouse features.  
U1 - AdderView GEM channels are switchable using a 3 button mouse

4.4 Keyboard hotkey combination  
The keyboard hotkey combination is used to change a channel, set autoscan mode  
or secure the product (so that the password needs to be typed before it can be used  
again). The following keyboard hotkey combinations can be selected. These hotkey  
combinations are used together with the command keys to trigger the required  
AdderView GEM function. The left and right shift key combination is particularly

suitable for extended keyboards where additional keys can be programmed to act as  
a combination of other keys. Such keyboards are supplied with many Gateway 2000  
computers. Programming spare keys to trigger the hotkey combination allows  
channels to be selected via a single key stroke.

4.5 Cycling between all channels or jus t the active channels  
The AdderView GEM can be set to cycle between all channels or just the active  
channels when using Hotkeys + Tab’ or a three button mouse to switch the channel.  
This avoids wasting time viewing channels that are not active. Option are:  
U7 – Cycle between all ports when switching with Hotkeys + Tab’ or three button  
mouse (default)  
U8 – Cycle between active ports only when switching with Hokeys + Tab’ or three  
button mouse  
4.6 Firmware functions (vers ion query, mous e res tore and res et)  
For technical support purposes, it may be necessary to find the firmware release  
version for the control software in your AdderView GEM. For example, if the release  
version is v1.29 the response shown to F1f will be a brief display of the digit  
1, then F2fwill be a brief display of the digit ‘2, then F3fwill be a  
brief display of the digit ‘9. You can reset all of the configured options back to the  
factory default states by typing F8f. Use options F5fand F6f  
to restore mouse function on disconnected PS/2 CPU mouse connections.

F1 - Display firmware first digit (Note: F1 is Ffollowed by 1NOT l)  
F2 - Display firmware second digit  
F3 - Display firmware third digit  
F5 - Restore PS/2 mouse function to the currently selected CPUs mouse port  
F6 - Restore IntelliMouse function to the currently selected CPUs mouse port  
F8 - Reset all configurations to factory default settings. An ‘r’ will show briefly on the  
display to confirm that the reset has been completed.  
4.7 Setting a s ecurity pas s word  
There are many situations where unrestricted access to corporate file servers or  
sensitive information needs to be controlled. In such circumstances, the AdderView  
GEM can be locked away in a room or secure cabinet and controlled remotely. In  
this mode typing the keyboard hotkeys together with 'L' will blank the screen,  
disconnect the keyboard and mouse from all of the computers and display P on the  
AdderView GEM display. Control can only be regained by typing the correct  
password on the keyboard.  
To set the password in configure mode, first type P then (return). The display on  
AdderView GEM will change to show =' and you can then type your password. The  
password is not case sensitive and can be any combination of key strokes, including  
the function keys, but excluding the (ctrl), (alt), (shift) and (return) keys. When you  
have typed in your password type (return) to register it in the stored memory. Do not  
worry if you type the password incorrectly, you can always re-enter configure mode  
and set the password again. If you have lost the password and the AdderView GEM  
is locked, the unit may be unlocked by powering down the AdderView GEM, entering  
configure mode at power on (see section 2.6), and performing a complete reset  
using the F8 function.  
NOTE - The password consists of a combination of key strokes rather like the code  
to a safe. The key strokes are not case sensitive and can include all the keys on the  
keyboard (except ctrl, alt, shift and enter). Consequently the following 'password'  
would be valid:

4.8 Cas cade query code  
The AdderView GEMs use a special query code’ to detect whether or not they are  
connected to another AdderView GEM. By default your AdderView GEM uses query  
code AD. SmartView (another range of keyboard / mouse / video switches from  
Adder Technology) units with firmware versions less than 1.09 used query code EF.  
This was found to conflict with a small number of other (rare) devices that used the  
same query code so an alternative query code was provided to ensure compatibility.  
Either query code may be used but you should make sure that all cascaded  
AdderView GEM and SmartView units are set to use the same query code. If any of  
the cascaded SmartViews have firmware versions less than 1.09 then the cascade  
query code for all the AdderView GEMs and SmartViews should be set to EF.  
L7 – Cascade query code = AD (default)  
L8 – Cascade query code = EF  
4.9 Res olving s low mous e problems  
Due to certain technical reasons some systems running particular combinations of  
operating system and mouse drivers are sensitive to small timing changes relating to  
mouse communications. The introduction of a switch like the AdderView inevitably  
causes some timing changes and in rare cases interactions have been observed  
that causes the mouse to run very slowly. Certain HP Vectra computers running  
later versions of Windows NT with Logitech mouse drivers and Logitech mice have  
been observed to exhibit such interactions with older switches. One solution to this  
problem is to change the mouse driver.  
The AdderView GEM is a high performance device that is carefully engineered to  
minimise such interactions and should not exhibit this characteristic. Nevertheless  
such interactions are unpredictable and so the AdderView is fitted with a feature that  
ensures that the mouse can never operate at a very slow rate regardless of such  
interactions. This feature is activated using the following options:  
L5 – Allow the mouse to run at any speed (default)  
L6 – Don't allow the mouse to run at very slow speeds

Appendix A. Cable and connector  
s pecifications  
IMPORTANT NOTE  
The maximum cable lengths s upported vary widely between devices and  
cables . It may be pos s ible to us e cables that are longer than thos e s pecified  
below with certain PCs and peripherals but this cannot be guaranteed. If you  
experience problems try us ing s horter cables .  
A1. Keyboard, monitor and mous e to AdderView GEM  
All of the shared devices plug directly into the relevant ports at the rear of the  
AdderView GEM. If you use an AT style keyboard you will need an AT (5 pin DIN  
female) to PS/2 (6 pin mini-DIN male) converter.  
Cable s pecification (s elf-powered operation):  
Keyboard, monitor and mouse cables should be no longer than 2 metres.  
Cable s pecification (with optional power adapter):  
Keyboard, monitor and mouse extension cables can be used to increase the  
distance from AdderView GEM up to 10m. Most keyboards and mice will also  
operate at distances of 20 metres.  
A2. AdderView GEM to PCs 1 to 4  
Cable s pecifications :  
Video - 15 pin high density male D connector to 15 pin high density male D  
connector wired as a standard VGA PC to monitor cable. There are two types  
commonly available. The best type cables which will give excellent quality are  
constructed with coaxial cable cores. Cheaper data’ cables are often used, but can  
degrade video quality if used over longer distances. Avoid using 'data' cables longer  
than 2 metres unless the video quality is not important. Good quality coaxial video  
cables may be run at distances up to 30 metres with little loss of video quality. If you

wish to make use of the DDC (Display Data Channel) capabilities of the AdderView  
GEM then you will need to use cables that have the DDC signalling lines connected  
(pins 12 and 15 on the 15-way video connector). Not all video cables have these  
DDC lines connected.  
Keyboard and PS/2 mice - 6 pin mini-DIN male connector to 6 pin mini-DIN male  
connector with all lines connected straight through (1-1,2-2 etc.). If the PC has a 5-  
pin DIN AT style keyboard connector you will need a PS/2 to AT keyboard adapter  
6-pin mini-DIN female to 5-pin DIN male (readily available). For interface powered’  
operation without the optional power adapter the cables should be no longer than 5  
metres (see section 2.4 for more details). For operation with the power adapter,  
cables should be no longer than 30 metres.  
RS232 s erial mice - these require a special converter to connect the RS232 lines  
present on the AdderView GEM mouse ports to the RS232 port on a PC.  
Cables should be no longer than 30 metres.  
NOTE - There are s everal common wiring s pecifications for 6-pin mini-DIN to  
9-pin s erial adapters . If you have an adapter that has been s upplied with a  
mous e it may have a completely different internal wiring to that s hown above  
and may not be compatible with the AdderView

Appendix B. Problem Solving  
Problem:  
Poor video quality with smearing fuzziness or ripple.  
Action:  
Use screened coaxial video cables to connect your devices to the AdderView GEM.  
Problem:  
Mouse does not move cursor on screen.  
Action:  
Ensure that the mouse and computer are both connected to AdderView GEM before power is  
connected and ensure that the AdderView GEM is powered on before the attached computer. Ensure  
that your software is configured to accept a Microsoft compatible mouse of the type that you have  
connected (PS/2 or RS232). If you move the mouse and the activity indicator (dot on 7 segment  
display) does not flash then the AdderView GEM is not receiving data from the mouse. Check the  
mouse connection to the AdderView GEM, try resetting the mouse using the reset function (section  
2.10) or re-powering the AdderView GEM. If you are attempting to connect the AdderView GEM to a  
CPU with a PS/2 mouse connection that has not been powered down then you will need to use the  
mouse restoration functions F5 or F6 (see section 2.11).  
Problem:  
Keyboard does not function or functions intermittently. Num lock light does not always come on when  
the num lock key is pressed.  
Action:  
Some older keyboards were designed for use with specific computers and are not truly AT or PS/2  
compatible. These are not common but if you experience problems try another keyboard.  
Problem:  
Mouse causes channel to change.  
Action:  
Some cheaper mice are not fully compatible with the AdderView GEM and can lose data causing the  
channel to be changed (if mouse switching of channels is enabled). If you experience this problem  
then change the mouse and use a Microsoft, Logitech, IBM, Compaq or Hewlett-Packard type. Ensure  
that you are using a Microsoft compatible mouse driver on your PC. Some other manufacturers’  
drivers may switch the mouse to use a proprietary mouse data format not supported by the AdderView  
GEM. If you have unplugged and re-connected a mouse to the AdderView GEM then ensure that you  
reset it using the mouse reset function (see section 2.10).  
Problem:  
Mouse jumps around the screen after disconnecting the mouse cable or powering down the  
AdderView GEM.  
Action:  
If you have disconnected and re-connected a CPU mouse cable or you have powered down the  
AdderView GEM then the mouse data format may be out of synchronisation with that required by the  
PC (PS/2 or Intellimouse). Try the restore Intellimouse’ function (F6) to resolve the problem or re-  
power the CPU.  
Problem:  
Mouse moves very slowly but otherwise functions correctly.  
Action:  
Change the mouse driver to a Microsoft type or take the action recommended in section 4.9.
