6.5 Rear Panel

The rear panel, shown below, provides a full set of terrestrial and satellite data interfaces.
Modem Rear Panel
Full connector pinouts are given in Chapter 11. From left to right, the rear panel consists of:
IEC Mains Power Connector/Voltage Selector/Fuse
The modem is designed to operate from a mains AC supply of 100-240V (-10%/+6%, i.e.
90V to 254V at the connector), 1 - 0.4A, 47 to 63Hz. The IEC connector incorporates two
fuses, independently fusing both live and neutral lines. Access to the fuses is provided by a
slide-out tray. Both fuses are standard 20mm type, rated T3.15A, of the slow-blow (time-
delay) type. ALWAYS REPLACE THE FUSE WITH ONE OF THE SAME TYPE AND
RATING.
Chassis Ground Stud
This is an M4 stud for connecting a safety earth conductor directly to the chassis of the unit.
Tx IF Output Option
This connector is a BNC female and can be used in either 50Ω or 75Ω-impedance mode.
The output power level can be varied from 0dBm to -25dBm.
G.703 BNCs
Two optional BNC connectors may be fitted. These provide an unbalanced G.703 interface.
Tx L-band Output Option
This connector is an N-type female and is of 50 Ω impedance. The output power level can
be varied from –5dBm to –30dBm.
