Configuration port — This 2.5 mm mini stereo jack serves the same serial communications
function as the Remote RS-232 port on the receiver board, but is easier to access than the
port on the board after the unit has been installed and cabled. The 9-pin D to 2.5 mm
mini jack TRS RS-232 cable
, included with the PowerCage enclosure, but also available
separately, part number 70-335-01 (see figure 11), can be used for this connection.

NOTES: • This port is for remote control of the transmitter or receiver, not for the
over fiber RS-232 link.
• This port parallels the Remote RS-232 ports on the boards. If an active
front panel configuration connection is made, the Remote RS-232 port
on the board becomes inactive.
• The maximum distances from the transmitter or receiver to the controlling
device can vary up to 200 feet (61 m). Factors such as cable gauge, baud
rates, environment, and output levels (from the unit and the controlling
device) all affect transmission distance. Distances of approximately 50 feet
(15 meters) are typically not a problem. In some cases, the unit may be
capable of serial communications via RS-232 up to 250 feet (76 meters)
away.
This port is RS-232 only, with the following protocols:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
