APPENDIX C: AUDIO/SERIAL SUPPORT

Appendix C: Audio/Serial Support

Single head KVM devices:

The Audio/Serial allows bi-directional stereo audio and a full-duplex serial data link to be sent across the regular interconnection cable in addition to keyboard, mouse and DVI video.

Dual head KVM devices and Media devices (no USB):

The Audio/Serial allows bi-directional stereo audio and a 3 wire (Tx/Rx - XON/XOFF) serial data link to be sent across the regular interconnection cable in addition to keyboard, mouse and DVI video.

To set up the extender’s audio and serial link, please follow all of the instructions detailed in this appendix. If you have any questions, contact Technical Support.

Serial Interface - Set Up and Operation

No setting up or user adjustments are required. Please note that the serial link is always active.

Please bear in mind that the Remote Unit’s serial port is wired as DTE (i.e. the same as that on a PC). To connect a serial printer (or other DTE rather than DCE device) to the Remote Unit, you will need a Null-Modem (crossover) cable between the Remote Unit and the printer.

A serial touch screen may be plugged directly into the Remote Unit.

Please note, that media- and Dual head KVM Extender support a 3-wire- connection only (Tx/Rx/GND). Attached devices must support software handshake (XON(XOFF).

Serial Interface - Handling Multiple Serial Devices (Singlehead KVM devices only!)

The extender’s serial interface transmits/receives six signals (3 signals in each direction). Normally four of these signals are used for hardware handshaking (in addition to TX & RX). However, because each handshaking line can support signals up to 19,200 Baud it is possible to configure the serial interface to handle up to three simple 2-wire (Tx/Rx only) serial links. Select XON/XOFF software flow control on the remote device and PC.

To do this you will need to construct a custom breakout cable. Please contact technical support for further information.
