The two variants of the CATX Dual Access Module are highly compact devices that allow you to share a single computer between two sets of peripheral devices. The CATX-USB-DA variant is not fitted with audio or serial ports but is otherwise identical to the CATX-USBA-DA model.
Host computer connections
The transmit module connects to various ports on your computer, it is then connect it via CAT 5, 5e or 6 link cables, up to 300m in length to AdderView CATx KVM switches and/or Adder extender receivers (either AdderLink X2 Silver, X200 or X100), The video displays, keyboard, mice and speakers are linked to the remote devices.
The transmit 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.
Resolutions and cable lengths
The maximum resolutions achievable are:
- 1600 x 1200 x 60Hz at 200m and
- 1280 x 1024 x 60Hz at 300m. (Requires Receivers with Skew)
Do not exceed 300m cable lengths in any installation.
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 unless locked out by the remote user station controls). 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.
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 a connected display or an Adder DDC Ghost device.
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.
Receiver unit connections
Up to two AdderView KVM switches, two AdderLink X2 Silver Receivers, two X200 or X100 Receivers or a mixture of these can be connected to the transmitter.
For details about connections at the receiver units, please refer to the guides for those devices.
