DDXI DVI/VGA KVM EXTENDER FAMILY 

52 

Appendix F: Audio/Serial Upgrade 

The Audio/Serial Upgrade option consists of daughter boards that allow 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 VGA/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 on the Dual Access 
model, 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. 

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. 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.
