Figure 3: Typical 4-channel configuration when using (2) MOD 232 Modulator, TX9 Emitter, and optional RX22-4 Receivers.
Four-Channel Configuration
WIR TX900, WIR SYS 4
1. Use the WCA 068 short coaxial cable (Figure 3 above) to link the two MOD 232 Modulators.
2. Connect the short coaxial cable to the “Baseband Output” jack of the first MOD 232 in the chain. Connect the other end of the
short coaxial cable to the “Baseband Input” jack of the second MOD 232 in the chain.
3. Each modulator is set-up to accept two audio inputs. When the modulators are linked, they can accept a total of four audio
inputs. Connect the input signals to the audio inputs in the back of the MOD 232 labeled “Input CHA” and “Input CHB.”
Frequencies are pre-set to 2.3, 2.8, 3.3, 3.8 MHz. Frequency selection can be adjusted by using the “Configuration Switches”
located on the back of the MOD 232 (see page 4).
4. Wiring the Modulator to the TX9 Emitter: Connect a coaxial cable to the “Baseband Output” jack of the second MOD 232 in the
chain. The other end of the coaxial cable will connect to the “Baseband Input” jack of the TX9. Additional TX9 Emitters can be
linked together as needed for coverage see Figure 3.
