Decoding
The incoming signals are decoded according to a built in
priority table.
Cross track and bearing information are 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 is available 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)
--- XTE -----
FRM BWW 12.5
OK BRG
POS-WP 224.9
OK POS/LAT
OK POS/LON
N 22°45.345
E123°34.456
--- COG ---
FRM SOG 12.5
--- WIND ---
--- SPEED ---
FRM DEPTH ---
If data are missing or invalid, perform the following:
•
Check the NMEA signal monitor (see below)
• Check the interface setup in the Installation Menu (page 98)
• Check the navigator setup and make sure it is transmitting
appropriate NMEA data.
• Perform a NMEA (hardware) test as per below.
NMEA signal monitor
Close to the NMEA terminals in the junction unit you will find a
green LED. A flickering LED indicates that an NMEA signal is
received. It does not, however, qualify the contents of the
message.
