N 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.
N The length of exposed wires is critical. The ideal length
is 3/16" (5 mm).
• If the stripped section of wire is longer than 3/16", the
exposed wires may touch, causing a short circuit.
• If the stripped section of wire is shorter than 3/16",
wires can be easily pulled out even if tightly fastened
by the captive screws.
N The rear panel Remote RS-232 port is active only if the
front panel Configuration port is not active. If an active
front panel configuration connection is made, the rear
panel Remote RS-232 port becomes inactive.
