Autostar 497, no serial response to unit, cables ok (checked with other 497), serial IC?
The 497 works as normal in telescope control and setup. It will not communicate with the Com 1 line from the computer. I suspect the AM 232 IC, but have no way to successfully solder a surface mount IC in, if that is what the problem is. Is there other options I should check? The worst thing would be I am stuck with firmware 42E and not computer control. That would not be my first choice. Thanks
