Congratulations on your purchase of the TMCC Accessory Voltage Controller
(AVC)! The AVC unit is the perfect way to
supply the proper voltage to each accessory,
prolonging the lives of the lamps and
reducing wear and tear on the motors. Use
one of the ten preset voltages, or customize
the voltage yourself!
Congratulations

Powering the Accessory Voltage Controller
Power your AVC using one of the options illustrated in Figure 1. A separate power supply is used in Option 1; the AVC is connected to the outside rail or common layout ground in
Option 2.
1. Attach one wire to the Power/A terminal of your transformer and connect it to the HOT
terminal on the AVC unit.
2. Option 1: Attach another wire to the Common/Ground/U terminal of your transformer and
connect it to the NEUT terminal on the AVC unit.
Option 2: Attach another wire to the outside rail and connect it to the NEUT terminal on
the transformer.
Refer to page 5
for accessory
connections.

Connecting the COMM wires
Your AVC unit will need to communicate with the Command Base and any other TMCC products you have connected to your AVC unit. To make these connections, you will need
the Command Base Cable (available separately, 6-14191 for a 6’ cable and 6-14195 for a 20’
cable). Follow these steps and refer to Figure 2 to connect your AVC unit to the Command
Base.
1. Connect the computer-style connector at the end of the Command Base Cable to the
COMPUTER terminal on the Command Base.
2. Connect the red wire at the other end of the Command Base Cable to the DAT terminal on
the AVC unit.
3. Connect the green wire to the COM terminal on the AVC unit.

Connecting additional TMCC products in a “daisy chain”
You may choose to power additional TMCC products using the same Command Base by creating a “daisy chain,” or a series of TMCC units wired in succession. To daisy chain the
POWER IN connections, attach one wire to the HOT terminal on the next TMCC product. Then,
attach another wire to the NEUT terminal on the AVC unit and connect it to the NEUT
terminal on the next TMCC product.
To daisy chain the COMM connections, attach one wire to the DAT terminal of the AVC unit
and connect it to the DAT terminal of the next TMCC product. Then, attach another wire to the
COM terminal of your AVC unit and connect it to the COM terminal of the next product. Add
additional products in the same manner, connecting the DAT terminals and the COM terminals.

Connecting your accessories to the AVC unit
Connect your accessories to the TRACK OUT terminals on the AVC unit as illustrated in Figure 3. In Options 1 and 2, the AVC and accessory are powered by a separate power
supply. In Option 2, the neutral is shared by the outside rail, the AVC, and the accessory.

Assigning an ID# to the AVC unit
Follow these steps to assign an ID# to your AVC unit so you can adjust the accessory voltages with your CAB-1 Remote Controller.
1. Slide the RUN/PRG switch to PRG.
This switch is located on the front of the AVC unit. Refer to Figure 4.
2. Press either TR or ENG (your choice) on your CAB-1 Remote Controller.
3. Select an ID# (0-9 for TR ID#s, 0-99 for ENG ID#s) and enter with the numeric keys on
your CAB-1 Remote Controller.
4. Press SET on your CAB-1 Remote Controller.
5. Slide the RUN/PRG switch back to RUN.
The ID# of the AVC unit has been assigned.

Using a preset voltage level
The AVC features three preset voltage ranges. The broadest voltage range allows you to set the voltage from 0 percent to 100 percent, or full voltage. Access this range by pressing H
on your CAB-1 Remote Controller as discussed below. The second voltage range spans from 30
to 80 percent. Press M on the CAB-1 Remote Controller to access this range. Finally, the last
range allows you to set the voltage from 20 to 70 percent of full power. Access this range by
pressing L on the CAB-1 Remote Controller as described below.
The voltages in each range are assigned numbers 0 to 9, where 0 is the lowest voltage and 9 is the
highest. The preset voltages increase at even intervals from number to number.
In the L and M ranges, pressing 0 turns the accessory voltage OFF. In the L range, 1
corresponds to 20 percent of full voltage and 9 corresponds to 70 percent of full
voltage. In the M range, 1 corresponds to 30 percent of full voltage and 9
corresponds to 80 percent of full voltage. Between 1 and 9, the voltage increases at
even intervals.
1. Press TR or ENG (determined when you assigned the ID#) and the ID# of the AVC unit on
the CAB-1 Remote Controller.
2. Locate the L, M, and H buttons beneath the front panel on the CAB-1 Remote Controller.
Press H for the full voltage range.
Press M for 30 to 80 percent of full voltage.
Press L for 20 to 70 percent of full voltage.
3. To save the selected voltage range, press SET on the CAB-1 with the RUN/PROG switch on
the AVC set to RUN.
To turn OFF accessory voltage, press HALT on the CAB-1 Remote Controller.

Setting a specific voltage
You may adjust the voltage to a setting of your choice with the red knob on the CAB-1 Remote Controller if you choose not to select a preset voltage. While turning the red knob
on the CAB-1 Remote Controller, you can examine the intensity of the lamps and the operation
of the accessories. Once you have fine-tuned the performance, you can save the voltage level.
1. Press TR or ENG (determined when you assigned the ID#) and the ID# of the AVC unit on
the CAB-1 Remote Controller.
2. Use the red knob on the CAB-1 Remote Controller to adjust the voltage. For fine
adjustments, use the BOOST button on the CAB-1 Remote Controller to increase the voltage
by one step or the BRAKE button to decrease the voltage by one step.
3. Press AUX1, AUX2, and enter a number from 0 to 9. The new voltage setting will be saved to
that number.
4. Press SET on the CAB-1 Remote Controller while the RUN/PROG switch on the AVC is set to
RUN.
At this point, a new voltage has been assigned. Press L, M, or H to reset the AVC to the factory default
settings.
