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
!
and the output power
level is -5 to -15dBm. In normal operation, the output will be a QPSK modulated result
of the DATA I/O connector between 50 and 90 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 and -55 dBm with a maximum composite level of 0
dBm. Signals between 50 and 90 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 90-132 VAC or 180-264 VAC, 47-63 Hz. Maximum
power consumption is less than 75 W.
Note:
Damage may result if the incorrect input voltage is applied to this connector. If
there is any question of the compatibility, DO NOT connect up the unit until EFDATA
has been contacted.
2.2.7 GND
A#10-32 stud is available on the rear for the purpose of connecting a common chassis
ground between all of the equipment.
2.3 System Requirements
The standard modem with all the cards installed (Figure 1-3), is full duplex QPSK
satellite modem. The system can also be configured for TX only or RX only.
For a TX only system, the demodulator (0778-X) and decoder (2133, 0949, or 0701) are
removed. You also must enter the Utility Menu on the front panel and select OP MODE
