RS-232 connections
The RS-232 Over Fiber port is for transmission of serial signals, such as projector control
signals, between the transmitter and receiver.
The Remote RS-232 port is for remote control of the transmitter and receiver. The protocol
for the Remote RS-232 port is as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
