Rich,
I'm not near my layout computer so I can't check the other settings, but the COM port depends on what Windows has assigned. Open Device Manager, expand the ports section, and plug/unplug the PR4 into the SAME USB port.? The COM port number that comes and goes when you do that is the one to use.
Also, I've found that sometimes I have to "reset" my PR4 by removing the USB and power, letting it sit for maybe 30 seconds, then plugging everything back in. That seems to fix the occasional flakiness (which is triggered by, as far as I can tell, by switching between PR4 modes of operation).
HTH,
