The auxiliary 1 (AUX 1) connector provides:
! MOD and DEMOD (TTL) faults
! Satellite Clock
! Satellite I & Q
! Automatic Gain Control (AGC) output voltage
The faults are open collector levels that indicate a modulator or demodulator failure. A
logic “1” indicates the faulted condition.
AGC_OUT is a programmable voltage, 0 to 10 V, for a receive signal level between
-25 and -60 dBm.
AUX 1 connection is a 9-pin female D connector (J9) located on the rear panel of the
modem. Screw locks are provided for mechanical security on the mating connector. Refer
to Table 2-6 for pinout information.
