Installation
The fault interface is provided on a 9-pin female D connector. Screw locks are provided
for mechanical security on the mating connector.
Pin #
Note: A connection between the common (COM) and normally open (NO) contacts
indicates no fault.

2.2.4 IF Output (CP1)

This is the transmit IF connector. The output impedance is 75
level is -5 to -30 dBm.
In normal operation, the output will be a QPSK-modulated result of the DATA I/O
connector, with a frequency between 50 and 90 MHz, or 100 and 180 MHz.

2.2.5 IF Input (CP2)

This is the receive IF connector. The input impedance is 75
For normal operation, the signal level needs to be between -30 dBm and -55 dBm, with a
maximum composite level of 0 dBm. Signals between 50 and 90 MHz, or 100 and 180
MHz, are selected and demodulated to produce clock and data at the DATA I/O
connector.

2.2.6 AC Power

The AC power is supplied to the modem by a standard detachable, non-locking, 3-prong
power cord.
Normal input voltage is 90 to 132 VAC, or 180 to 264 VAC, 47 to 63 Hz. Maximum
power consumption is less than 75W.
