Troubleshooting
Before contacting the distributor or dealer for support, please check the following troubleshooting guide.
Troubleshooting guide:
1)
Power cycle the unit to verify that the problem still exists
2)
Is the communication cable properly connected?
For more information on connecting cables, see Connecting on page 20.
3)
Check the status of the Red and Green LEDs.
If everything is correct, then the green LED shall lit and the red LED shall non-lit.
For further details on the LEDs, see
DIP-switch and LEDs
on page 21.
4)
Check that the DIP-switch has been configured properly.
NMEA 0183: 4.800 or 38.400 baud (factory default: 4800 baud)
NMEA 2000: ‘Open’ or ‘Terminated’ (factory default: ‘Open’)
For further details on the DIP-switch, see
DIP-switch and LEDs
on page 21.
5)
Using NMEA 2000 - check your navigational equipment for correct selection of the LT-1000 NRU as
preferred source (Heading, GPS, Environmental). Check that the LT-1000 NRU is supporting the
expected NMEA 2000 PGNs; see App. E - NMEA 2000 on 40.
6)
Using NMEA 0183 - check your navigation equipment for correct baud rate. Check that the LT-1000
NRU is supporting the expected NMEA 0183 Sentences; see App. D - NMEA 0183 on page 38.
7)
Connect the LT-Service Tool (see Connecting LT-Service Tool on page 25 and Configuration using LT-
Service Tool on page 29). Check and record the following commands in the LT-Service Tool:
a.
Write “status” and check for errors and warnings
b.
Write “nav” and verify navigation data is as expected
c.
Write “mon” to monitor NMEA 0183 output
8)
If any configuration has been applied in the LT-Service Tool, make sure that you have used the
“reboot” command and check that the new configuration is properly configured after the LT-1000
NRU has power up again.
If none of these troubleshooting steps have re-solved the problem, please contact your local distributor or
dealer for further action and support.
NOTE:
It is recommended, that the end-user makes contact to the local distributor or dealer for
technical support on the product, as they have information and experience with the product.
