EDID display information
The module contains a default set of EDID information that supports display resolutions up to 1920 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.
