After trying with the TTL to RS-232 converter, nothing works....No way. We have try even directly to the computer, without success....
After that, we have made the modification on the PCB, and after switching on, the newly installed MAX232 got really really hot.....
At the moment, rotator only works using the mini usb conector on the Rotator Control.
We are wondering if we can convert the COM1 RS-232 to USB and then use the cable that is working now....
We need sone help
