Configuration port — This 2.5 mm mini stereo jack serves the same serial communications
function as the Remote RS-232 port on the transmitter or receiver board, but is easier to
access than the ports on the boards after the units have 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 13), 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 m) are typically not a problem. In some
cases, the unit may be capable of serial communications via RS-232 up
to 250 feet (76 m) away.
This port is RS-232 only, with the following protocols:
•
9600 baud
• no parity
• 8 data bits
•
1 stop bit
• no flow control

Temp LED —
This LED lights to indicate that the temperature within the PowerCage
enclosure is dangerously high (above 167 °F [75 °C]) and that equipment damage is
imminent
