Tonight my EQ6 synscan hand controller started playing up when I went to park the scope. It looks like a number of the buttons on the left hand side of the keypad are not responding including the ESC, 1 and 2 buttons. The other buttons seem to be working fine.
Peter,
Have you tried doing a firmware update?
At least this will help you find out if it is a hardware or software problem.
What version software was it ? I had heard the V3.22 did have some lockup issues.
Also I did have problems installing firmware with a USB/serial convertor with the original firmware loader but that appears fixed with firmware loader V2.8
I had a problem with the cable in general - some pins had become disconnected with the poor soldering job. But it was a fairly easy fix, just getting the right pinouts.
