Hi Jim,
What about opening the com port in a serial terminal program and sending and receiving commands and feedback from the interface?
Good idea. Had to find a reference for the GS-232 command set, but Google quickly found that. As far as I can tell, the only commands that work are C, C1, & C2 which gives the Azimuth, Azmuth, & Azimuth and Elevation (although not in the format that the reference I found says it should be). The numbers match what the FoxDelta display shows - which also match the G-5500 control box meters. All other commands result in a response of: ?>
If you built your interface, make sure the voltage regulator is soldered in correctly and everything is running at 5V. I managed to have my regulator in backwards and everything including the USB chip was running at about 9V.
This was a purchased completed unit from FoxDelta.
