As well as the general handset make, Skywatcher or whoever. I think you will have to supply the model of the handset as well as the scope. Meade for example make at least 2 different ones for their ETX range, then they have the bigger LX's on what I presume will be a different handset model as well. Which could easily have a different wiring.

The handsets often have a crossover in them to entice you to buy the manufacturers cable.

If you bought the mount new it would have come with a cream cable that plugs into the bottom of the handset and has a serial plug on the end. If your computer doesn't have a serial plug you need a usb-serial adapter (the prolific chipped ones are known to work).

There's a diagram of the RJ11 to RS232 wiring on page V of the Appendix B of the Skyscan Instruction manual. This can be downloaded from the Skywatcher site.

Pins 2 3 and 5 from the RS232 are connected to the 2 5 and 3 pins on the RJ11

RS232

2 = RD

3 = TD

5 = GND

RJ11

2 = RD

3 = GND

5 = TD

Hope this helps
