Hi All This is another USB question that I can’t find the answer to. I’ve being controlling my lx200 classic from my desk top computer using the serial port (DB9) to the RS232 port on the telescope and it works fine. I now need to go from a USB port to the RS232 port I have a USB to serial adapter to do the conversion from USB to the RS232 port. I have what looks like no comminution to the rs232 port on the telescope. When the USB to serial adapter is plugged in to the computer it is recognised straight away and also shows up in the device manager’s property’s page under com ports as Prolific USB to Serial com port (com4). I have also changed the com. Port assignment in the control software to match. No luck there. Do I need to make up a new cross over cable or change the wiring around from the serial end of the adapter to RS232 port on the telescope? Any help would be greatly appreciated to help me resolve this problem so I can continue to set up my wireless control system. Thanks in advance for the help
