Control Software for Windows

The included Extron QSD 204 Control Program for Windows offers another way to control the QSD 204 via RS-232 connection in addition to the Simple Instruction Set commands.

The control software is compatible with Windows 95/98, Windows NT, and Windows 2000. Extron’s QSD 204 Control Program is included with the decoder, and updates can be downloaded from the Extron Web site (http://www.extron.com).
