NOTE: If RB24 or RB115 Relay Box is not used, maximum cable length is distance “B.”
* Conductors are for up, down, left, and right functions, plus motor common. Cable distances are calculated with both
motors (pan and tilt) running and assuming a 10% voltage drop in the cable.
** Same as five conductors except two wires are used for motor common.
*** Not recommended for reliable service between control and relay box.
