SC-2 wiring and operation
Four wires (not included) are needed to connect your Railroad Control Tower to the SC-2
and a separate accessory transformer. Refer to Figure 4. We recommend using 22-gauge wire.
1. Attach one wire to the transformer’s Common/Ground/U terminal and connect it to the
accessory COMM (common) position on the SC-2.
2. Connect one of the Railroad Control Tower terminal labeled “L” to the accessory ON/OFF
toggle position on the SC-2.
3. Connect the Railroad Control Tower terminal labeled “M” to the momentary position on
the SC-2
4. Finally, connect the Railroad Control Tower terminal labeled “G” to the transformer’s
Power/A terminal.
Press and hold the AUX1 button to activate the animation. Use the AUX2 button on your
CAB-1 Remote Controller to toggle the lamp ON and OFF.
