NOTE For the RS-232 Over Fiber port, only cross the Tx and
Rx lines once between the source and the target.

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.

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
between them.
•
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 in use. If a front
panel configuration connection is made, the Remote
RS-232 port becomes inactive and the front panel
Configuration port is active.

These ports are for remote control of the transmitter or

Configuration port — These 2.5 mm mini stereo jacks serve
the same serial communications function as the rear panel
Remote RS-232 ports, but are easier to access than the rear
ports after the units have been installed and cabled. The
optional 9-pin D to 2.5 mm mini jack TRS RS-232 cable,
part #70-335-01 (figure 2-12), can be used for this connection.
