Resolutions and cable lengths
The maximum resolutions achievable are: 
1600 x 1200 x 60Hz at 200m and  
1280 x 1024 x 60Hz at 300m. 
Do not exceed 300m cable lengths in any 
installation.
Host computer connections
The module does not require a power adapter 
because it derives all of its power from the host 
computer. Therefore the USB cable must always 
be connected to a USB port on the computer that 
is capable of providing up to 500mA.
Receiver unit connections
You can connect two AdderView KVM switches, two AdderLink X2 
Silver extenders or a mixture of both.
For details about connections at the receiver units, please refer to 
the guides for those devices.
Disabling/re-enabling receiver connections 
When required, a user of one remote link can disable (and re-
enable) the other remote link using serial port commands (this 
feature is available only on the CATX-USBA-DA models). To do 
this you need to determine two things: a) The Com port to which 
the serial connector is attached and b) which of the two remote 
ports you are using (A or B). See also ‘Serial port configuration’.
1  From one of the remote keyboards, open a terminal program 
on the computer and use it to send the appropriate character 
to the Com port to which the module is attached:
  Port 
Disable character 
Enable character
   A 
a (0x61) 
A (0x41)
   B 
b (0x62) 
B (0x42)  
  The module will return OK or FAIL to indicate the result.
  Note: Take care not to disable the port that you are using. If 
you do, either re-power the module or use the other remote 
link to re-enable your link.
2  Re-enable the port when it is appropriate. Note: Whenever 
the module is re-powered, both links will always be enabled.  
EDID display information
The module contains a default set of EDID information that 
supports display resolutions up to 1600 x 1200 @ 60Hz. In 
addition, the module will check during power up whether 
alternative EDID information is available from the KVM switch or 
extender that is connected to port A. If required, you can also 
harvest and store new EDID information from your display or an 
Adder DDC Ghost device. 
User arbitration
Control of the host computer is arbitrated by the 
module on a first come, first served basis. At the moment that 
a key is pressed or a mouse is moved by a user, the keyboard and 
mouse of the other user are temporarily locked-out (the video images 
remain). The keyboard indicators of the locked-out user then begin to flash to 
confirm their status. After two seconds of inactivity from the user currently in 
control, the module returns to its idle condition and re-instates the keyboard 
indicators of the locked-out user.

Serial port configuration
The module can automatically alter its baud rate to match that 
of the host computer’s serial port. To do this the other serial 
parameters must first be correct: 8 data bits, no parity, 1 stop 
bit and no hardware handshaking. These are usually the default 
settings, however, if you do need to alter them, open the Windows 
Device Manager, locate the entry for the COM port to which the 
module is connected and view the Properties > Port Settings tab. 
Once set, open a terminal program and send a Return (carriage 
return) to the Com port to which the module is attached until the 
message 
USB Dual Access CAM version 1.00 is returned. The 
module can now accept commands.
