5. On the NMEATest screen, click Start. NMEA data should begin to display
on the NMEATest screen. Additionally, NMEA data should begin to
display appended to the SBE 45 data in SEATERM on computer 1. The
yellow
NMEA LED should flash on the Interface Box each time the
simulation program transmits a new position. The appended data should
correspond to the most recent simulation program data. For example, if
NMEATest is set to output RMC data:
NMEATest output -
RMC: 2212.345,N, 04459.876,E, 15 May 2002 00:00:22
SEATERM output (appended after SBE 45 data and optional SBE 38 data) -
lat=22 12.345 N, lon=044 59.877 E, hms=000022, dmy=150502
See
NMEA Raw Message Formats for the NMEA message formats.
If properly decoded data appears in SEATERM, the Interface Box is working
properly. If the system works with the simulation program but does not work
when connected to the actual NMEA navigation device, the problem is with
the cable from the NMEA navigation device to the Interface Box, or in the
NMEA navigation device itself.
•
Verify that the cable pinouts are correct, especially at the NMEA
navigation device. See
Connections, Switches, and LEDs in Section 2:
Interface Box Description and also refer to the NMEA navigation device
documentation.
•
If the cable is correct, verify that the NMEA navigation device is on and is
configured to send data. Many NMEA navigation devices have
programmable NMEA outputs and may need to be configured before they
will transmit NMEA messages. Refer to the NMEA navigation device
documentation, or contact the device’s manufacturer for customer support.
