Scott,
You will have problems with inaccurate rotator position indication if you use 4
wire cable on the Orion 2800 rotator. Noise from the motor causes the position
indicator to read false pulses if the two small wires are in the same cable as
the large motor wires.
I use two separate cables on my Orion rotators. The position indicator has
been completely trouble-free, despite the 500 foot cable lengths.
