Power Connection for U.S. Application
1. Connect the TFP 016 power supply to the 3-pin Molex connector located
on the rear of the MOD 232.
For Applications Outside The U.S. Requiring 240 VAC Mains Supply:
Use the transformer power supply, model TFP 027. Secondary specifications:
24 VAC, 35 VA, 50/60 Hz.
2. Plug the power supply into the AC outlet.
Baseband Cable Connection
The MOD 232 can directly drive one or two emitters. TX9 DC 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 DC 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 DC Emitter.

WIR TX9 EMITTER (REAR)
Connect to the TX9 DC 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. Connect the baseband output from the second modulator in the chain to the TX9 DC emitter(s)
baseband input connector.
