Re: Serial COM with old IFI controller

The 2005 controller uses the 8520 processor. You will need to make sure the libraries match that processor. The newer (2006 and up) controllers use the 8722 processor.

The baud rate settings for the programming port was 155.2kb 8-1-N I think.

You also need a standard 9-pin serial port and cable. The problem may be in the cable itself. Some serial cables are not standard 1-1 pinouts. HP was also finicky with having non-standard RS232 port pinouts. A USB to serial converter may not work in this application.

i hope this helps
