Just got myself a UHF XTS5000 and a programming cable off of ebay to program it with. I have CPS V. 06.12.05 installed on a computer running Windows 10 64 bit. As for the cable, I have the programming cable in parallel with a USB to serial cable and drivers are installed for that. CPS fires up fine but when I click File > Read Device it gives me a drop down list of ports to choose from with only one choice and that being COM3. When I click ok after selecting COM3, I get the "Couldn't open port Check whether device/RIB are powered on or not and the device to RIB and the RIB to PC connection is OK" error. Any ideas?
