TEST NMEA – collection of NMEA Interface Tests
In this mode Tester allows receiving all information incoming to presentation ports
of AIS station, such as pilot plug or from GNSS receiver. If it is necessary to
receive the information from pilot plug select the 38400 Baud rate, or select the
4800 Baud rate to check the vessel’s sensors (for example, GLONASS, GPS,
gyrocompass etc.).
The tester allows connection to interface with RS 422/485 or RS 232.
Step 1.
Receiver bit rate
: select bit rate:
38400 baud
