GTOCP3 controller.

Bluetooth unit works a treat with Astro-Physics mounts. Get one of these units!

Mine was a custom job by Tex. That unused, +6V (Pentax 6x7) 3.5mm mono output on the GTOCP3, that now powers my bluetooth unit perfectly. No need for a bulky, external power pack. No worrying about battery levels or charging. Constant power! All cables necessary to make this happen were fashioned by Tex and included in my order. Superb service! Couldn't be simpler!

I'm using the primary (upper serial port) connection on the GTOCP3, as Roland would recommend, but preliminary tests are showing the secondary (lower serial port) to work as well, which means you could, in theory, leave your AP hand controller plugged in. TBC.
