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 ow control

Do not tin the wires!
