Using the USB COM Port
Step 1:
Ensure the USB drivers have loaded and determine which COM port your USG-2 has been allocated by the
Operating System (OS). Instructions for how to do this will vary depending on your PC OS, for Windows OS
refer to Device Manager’s ‘Ports’ section.
Step 2:
The COM port must be opened at the same baud rate as the NMEA 0183 device connected to the USG-2.
