InFocus network control uses the Telnet packet structure.
For network control, you can access the projector through Port 23 (Telnet). We use the same control codes over serial (RS232) connection as well.
To control a projector via RS232, connect a null modem cable and set the control system serial port settings to match the following communication configuration.
Bits per second 9600
Data bits 8
Stop bits 1
Flow Control None
For a command list look up your specific projector at www.infocus.com and go to downloads. You should find an RS232 document for the projector if RS232 communication is supported.
