DeLorme Earthmate Hyperformance GPSr compatible?

I'm using Global Mapper 11.01 and an Earthmate "Hyperformance" GPSr (serial) with a USB-to-Serial adapter (computer doesn't have any serial ports). Under Windows device manager, I can see the adapter is set to COM3. But when I setup the GPS in GM to use COM3 (auto-detect), I always get an error message saying that GM was unable to auto-detect any GPS device.

I've even tried setting it to NMEA and trying COM1 thru COM5 just to be sure, but nothing works.

Is my GPSr compatible w/ GM11, or is it too old and unsupported?

FYI: My GPSr works just fine in DeLorme's Street Atlas 2007 Plus, which I'm not running at the time so there shouldn't be any COM port confusion.

Please help. Thank you.

    The original DeLorme serial GPS receivers don't use NMEA but instead use the old Rockwell binary format, which is not supported by Global Mapper. There is a hardware translator available at, but really I think an upgrade to your GPS receiver would be a better investment.

    Let me know if I can be of further assistance.
