Troubleshooting
When your GM-2 could not operate, please follow below instructions for
troubleshooting.
1.
No LED light after plugged in
It means no power is applied to GM-2. Please check if the connector plugs
in properly.
2.
GM-2’s LED is flashing, but the connection between GM-2 and the E-map can
not be established. Please make sure the settings of COM Port Number and Baud
rate are correct.
Most of E-map provides scan function to search COM Port. Please scan
it for the correct COM Port number that GM-2 is utilizing.
The default Baud rate is 9600 (Receiver type only). Logger type is set
at 115200bps. For COM port, please go to the MS Windows’ device manager
to check the correct COM port first.
If a USB cable is used to connect to PC/Lap top, please make sure the
UBS driver is installed successfully.
