NSTALLATION
A complete modulator consists of the SDM-2020 main unit and an optional plug-in data
interface. The modulator is shipped with the data interface installed in the unit. Changing
a data interface is easily accomplished in the field and does not require disassembly of
the main unit.
Refer to applicable chapters for information on removing and installing data interface
modules.
Install the modulator as follows:
1 Optional: Install the mounting bracket in equipment rack (Figure 3-1). Install and
tighten the bracket bolts.
2 Loosen the screw with flat washer located on the left-side of modem chassis.
Mount the modem chassis into the equipment rack and slide the screw with flat
washer through the slot of the mounting bracket. Tighten the screw sufficiently to
allow the modem chassis to slide in the bracket.
3 Connect the cables to the proper locations on the rear panel.
4 Observe the modulator. The modulator powers ON automatically when the
primary power connection is made (plugged in). Before plugging in the modulator,
become familiar with the front panel operation as described in Chapter 5.
