7.3.1 Power Connection

The power cable with a rated capacity of 3A should be used. Pin definition for the connector is
showed above.
Suggest using the 3A DC Power Supply Unit (DC 24V output).

7.3.2 GNSS Data Output

There are totally three RS422 GNSS data ports. The output data format is NMEA0183, as
IEC61162-1 standard.
The default baud rate is 4800 bps, which can also be changed among 9600 / 19200 / 38400
bps.

7.3.3 Grounding

radio equipment. Ground the unit as follows to prevent interference:
• The ground wire should be 1.25mm
• The ground wire should be as short as possible.
