I am using com port1 and have adjusted all the settings to match the receiver's software. I am not sure, but I think I got a stright through cable? this could be the problem,eh?
Has anyone had success with using the software to update this receiver as found here: DBS-3500 software . Every time I try to use it is says "serial port probe error". I have tried it on 4 different computers and it does the same thing. Thanks.
