Appendix E: Audio/Serial Ports

Operation & Multi-Port Configuration

This appendix describes audio & serial interface operation for those models that have this feature:

•ACU2022A

•ACU2028A

•ACU2222A

•ACURA001A

•ACURA002A

These extender products contain daughter boards that allow bi-directional stereo audio and a full-duplex serial data link to be sent across the CATx interconnection cable in addition to PS/2 keyboard, mouse and video.

Serial Interface - Set Up and Operation

No setting up or user adjustments are required. Please note that on dual access Local units, the serial link is always active.

The Remote unit’s serial port is wired as DTE - 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. Select Xon/Xoff software flow control on the printer and PC.

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

Serial Interface – Handling Multiple Serial Devices

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.

To do this, you will need to construct a custom breakout cable. Please contact Technical Support for further information.
