6.2 NMEA Test
The NMEA test menu is accessed from the User Set Up Menu (page 27). It
provides you with status information of the different NMEA messages used
in the system.
Decoding
The incoming signals are decoded
according to a built in priority table.
Cross Track and bearing information is
taken from the NMEA messages with
highest priority.
One of the following codes will be
displayed:
--- No data or no NMEA sentence
containing the data needed at the input port.
OK Valid data found
INV Message with invalid information.
FRM Message has format failure such as
a) Incorrect check sum
b) Wrong contents in datafield(s)
Check status and set up of data source.
NMEA signal monitor
Close to the NMEA terminals in the
junction unit you will find a green LED. A
flickering LED indicates that a NMEA
signal is received. It does not, however,
qualify the contents of the message.
