All connections to the Adder TD161 are made at the rear panel; see Figure 4.
2 Amp Fuse A 2-amp time delay power fuse is at the left side of the rear
panel. Be sure to use the same fuse type if replacement is required.
Power Input Connects the power supply delivered with your Adder TD161 to the
module. Any other power supply used with the Adder TD161 must
provide 1.5 amperes continuous at 13.8 VDC.
Note: Although the module will operate at 12 VDC, 13.8 VDC is required to charge the
internal reserve battery.
Fiber/Coax RX Multiplexed optical and electrical signal inputs to the Adder TD161. The
module will switch to the first of these connections that provides an
active input.
Fiber/Coax TX Multiplexed optical and electrical signal outputs from the Adder TD161.
Note: Regardless of the input used by the module, both outputs are always active and
exactly reproduce the received multiplexed audio and data signal.
Note: This receptacle is not the same as on the Adder 161 which utilizes XLR
connectors for both audio inputs and audio outputs.
Data 1/Data 2 Demultiplexed digital data and switch closure information that was
input to the source Adder 161 TX transmitter. The pin numbering is
shown in Figure 4 and the signals on these pins are described in Table
1. Odd Channel Output and Even Channel Output are the audio
outputs for the odd and even channels selected for tap and drop by
the Output Selector switch on the front panel ( Figure 5). The signals
are obtained from the + and - wire terminals on the rear panel and are
balanced to ground. The connecting terminal block is delivered with the
Adder TD161.
