A USB to serial converter gives you the equivalent of a straight RS 232 cable. Some receivers need a Null modem cable. If things do not work, it is best to go out and buy a null adaptor and attach in series. That way if you started with a straight RS232 you will end up with a Null, and if you started with a Null set up you will end up with a straight RS232.
