I have the GMC-320+ and in an attempt to load the USB COM port driver I have not had any success running Window 7 SP 1.
I am using USBDriverV4 that I have got from the download link.
My understanding this should emulate com3 by default. When I look at the device manager I do not see this enabled.
Am I using the wrong driver?

looks like the device is not connected to the computer.

If driver issue, there should be a "Unknown device" in the list.

Check the USB cable and connection.

Thank you for the reply. I had found it showing up after a few/many reboots.
The baud rate for my machine seems to like 115200, yet the Data Viewer always starts with a default of 57600. So I have the GMC320+ set to 115200 where it says it is the default rate. I still need to go into the data viewer settings to select the proper rate for the serial port every time I start and run the program.
I now have this set to upload to the map page and all seems to be now functioning as it should.
I have not tried to view saved data, but that should be forth coming now that I can link the two machines

Again Thanks,
Craig
