Ready to plug it into the telescope? NO!!! NOT YET!!!

First, remove the serial adapter, completely unplugging it from the Arduino.

Get out your multimeter, and select the "Ohms" measurement. One by one, double check that each pin on the Arduino is connected correctly to each of the numbered contacts on the RJ12 connector.

Do this by measuring resistance from the Arduino pin to the RJ12 contact. Each connection should show a very low resistance value, either 0 ohms or as much as 2 ohms.

You'll have to press the probe tip quite hard and straight onto the RJ12 to make a connection with each contact there.

When done, check the contact 3 connection AGAIN: it should connect to the "RAW" pin on the Arduino. Great. Put it all aside, have lunch, and come back and check every connection AGAIN!! Tedious perhaps, but better than destroying the electronics in the telescope mount!

If you still have the slightest bit of doubt, then email me a photo of your 6p6c (RJ12) connector (gold pins up), along with a photo or list of which colour wires you have connected to which pins, and I will endeavour to verify the wiring for you!
