I have lost RS-232 communications between my PC and Gemini 1. Worked fine a week ago. Not today.
We had a storm in between, local lightning strikes, driving rain etc and the Losmandy gear was set up in the Obs - plugged into the wall but not turned on. The storm was so sudden I couldn't get to the Obs in time to unplug everything. Damn.
The Gemini had lost date and time - I have had to reset that - but other defaults seem to have remained - location etc.
I've checked the integrity of the connecting cable and have installed the USB-RS232 cable on a different USB port and also installed a second USB/RS232 but neither seems to be able to connect.
Maxim reports that it can't find the Gemini.
I've opened the Gemini and checked that the RS232 connection is sound - no cracked solder points etc and no sign of any burnt chips etc.
Not sure where to go from here.
Any suggestions?
