Computer Access Module

Share a single computer between two sets 

of peripheral devices

FEATURES

Resolutions and cable lengths

The maximum resolutions achievable are: 

1600 x 1200 x 60Hz at 200m.

1280 x 1024 x 60Hz at 300m. 

Audio

Two channel CD quality audio is 

supported.

Absolute mouse mode support

Supports absolute mouse mode when 

used in conjunction with supporting 

equipment.

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 (Read and Store).

Power

The CATx Dual CAM uses a USB port to 

derive its power from the host computer, 

dispensing with the need for a separate 

power supply and thus simplifying 

installation.

Therefore the USB cable must always 

be connected to a USB port on the 

computer that is capable of providing up 

to 300mA.

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.

RS232 for 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. 

From one of the remote keyboards, a 

terminal program on the computer can be 

used to send the appropriate character to 

the COM port that has been allocated to 

the module.

PRODUCT IN BRIEF

The CATx Dual Computer Access Modules  
(CAMs) are highly compact devices that 
allow you to share a single computer 
between two sets of peripheral devices. In 
simple terms the CAM can be viewed as a 
combined video splitter and peripheral hub.  
This is useful for mixing local and remote 
stations or mixing KVM with extension or 
signage systems.

The module connects to the video, USB, 
audio and RS232 ports of your computer 
and then connects via CAT 5, 5e or 6 

cabling to the AdderView CATx KVM 
switches and/or Adder extender receivers 
(either AdderLink X100 or X200), each 
of which can be located up to 300 meters 
from the module. Your video display, 
keyboard, mice and speakers are linked to 
the remote devices.

The CATX-USB-DA variant is not fitted 
with audio or serial ports but is otherwise 
identical to the CATX-USBA-DA model.
