Adder™ TD161
Powering Up
Note: Never try to move the power switch on the front panel without first pulling on the
switch lever to disengage its lock.
With power off, check all electrical and optical connections as described under Rear
Panel Connections on page 4 and under Optical Connections on page 5. Firmly seat
and latch all connectors.
1. Pull the lever away from the panel.
2. Move the lever up for power on (or down for power off).
3. Verify that the External Supply LED is illuminated, and that the Internal Power
LED is green.
Note: If the Internal Power LED is red, the unit is drawing power from the internal
battery backup.

Setup
The TD161 Setup Procedure:
1. Connect an input fiber or coaxial cable from an Adder 161 TX or another TD161.
2. Connect the audio terminal block odd and even channel outputs and, if being
used, connect the DB-9 connector data outputs.
3. Use the Output Select rotary switch on the front panel to choose the set of odd-
even audio channels to be tapped from the fiber.
4. If you intend to tap digital data only, set the Output Select switch to either of the
Mute position.
5. Insert a small screwdriver into the rotor hole in the rear panel (Figure 4 on page 4)
and turn to the desired channel pair.
Note: The channel selection has no effect on the data outputs. These are always on
and present the same data as is received at the input fiber.
6. Connect an output fiber and/or coaxial cable to the output ports of the TD161. Run
these to another TD161 or to an Adder 161 RX.
7. If this TD161 is the last module in a branch of a cascaded system, place the
protective plastic cap on the module’s fiber output connector.
