Cable distances are for both motors running and assuming a 10% voltage drop in
the cable.
Six-conductor cable, single common conductor is recommended. Distances are
approximate maximum recommended under the following conditions:
Simultaneous pan/tilt activation
Minimum 21.6 volts at pan/tilt
Operating distance may be extended by using an RB24 remote relay box. Refer to
Table B for extended cable distances.
