Fully agree on using FTDI chipset -- historically these have been more compatible and stable converters for use with Gemini.

Here are dons more but I do like FTDI chipset converters. Their compatibility unmatched. ?
Below is Digikey line up of these RS232 To USB.?
?
Mouser also sell them. ? Buy from known sources as many converter chips are cheap copies. ?
This shows G1 and G2 Rs232 cable wiring. ?They are not the same.?
?
Also you haven¡¯t yet checked that your G1 RS232 IC is working. ?I¡¯d suspect that before replacing cables. ? See Gemini 1 FAQs?
?
In cases like this it¡¯s best to try run the Gemini using your cables and Gemini ASCOM to ensure the Gemini RS232 IC is ok. ? ?They have been known to go bad. ? It just simplifies it all. ?Trying to fix a bad IC by replacing cables does nothing but make confusion.?
Try this, G1/Gemini ?ASCOM connection via USB/RS232 and get back to us if it works. ?We can advise from there. ??
