Installation guide

Connect to the TX9 using RG-58 cable and BNC connectors. The MOD 232 has two baseband output
jacks to simplify connections when multiple emitters are used.

To setup a system for four
-channel
operation,
two
MOD 232 Modulators are required. Link the two
Modulator units together as shown in Figure 4. Connect the baseband output from the second modulator
in the chain to the TX9 emitter(s) baseband input connector.
BASEBAND CABLE CONNECTION
The MOD 232 can directly drive one or two emitters. TX9 emitters repeat the baseband signal, so any
number of emitters can be used. The modulator outputs CANNOT be split with CATV splitters.
Determine the length of RG-58 cable needed to reach from the TX9 Emitter to the Modulator unit.
Install BNC connectors to each end of the cable.
For
two-channel operation, only one MOD 232 is required: Connect the coaxial cable to one of the
Baseband Output jacks on the rear of the MOD 232. The other end of the coaxial cable connects to the
Baseband Input jack of the TX9 Emitter. See Figure 3 below.
