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
Do not tin the wires!
