6 E108-Product test
6.1 Serial port assistant
Test based on E108-GN01-TB, if there is no test board, you can refer to the backplane schematic diagram in the data package (this test content
is also applicable to E108-GN02/D).
1. After connecting the GPS antenna, connect to the computer through the USB cable at the same time, there is a USB port on the opposite side
of the antenna of the board, and then press the switch button to turn it on.
2. Note that when using an active antenna, the two pins of RF_POWER need to be short-circuited with jumpers.
3. You can open the serial port assistant to view the data reported by the serial port, or use our naviTrack to view it.
When the baud rate is set to 9600bps, data will be reported all the time after opening the serial port. The common output format is as follows:
GGA: time, location, number of satellites;
GSA: GPS receiver operation mode, satellites used for positioning, DOP value, positioning status;
GSV: visible GPS satellite information, elevation angle, azimuth angle, signal-to-noise ratio;
RMC: time, date, position, speed;
VTG: ground speed information (for details, please refer to the NMEA0183 protocol;);
