APPENDIX A. Troubleshooting
Situation
Possible cause and required actions
LED does not signal
when NMEA 2000 is
turned on
1. No power supply on the bus.
Check if the bus power
is supplied (NMEA 2000 network requires a separate
power connection and cannot be powered by a plotter or
another Device connected to the network).
2. Loose connection in the power supply circuit.
Treat the Device connector with a spray for cleaning
electrical contacts. Plug the Device into another connector.
Device flashes
GREEN-GREEN-
RED-GREEN, but
no data is available
on MFD
1. Network error.
Check the list of external devices or
NMEA 2000 devices on MFD and be sure that Outboard
Gateway (and other devices, if you have) is present in
the list.
2. Wrong settings.
Reset the Device to factory
settings (see the Section V) and run the engine at idle
revolutions.
RPM readings are
several times higher
or lower
1. Wrong divider.
Check the RPM divider setting
(Section III.3).
No RPM readings at
high revolutions
1. Wrong algorithm.
Check the pulse counting algorithm
setting (Section III.3), set the algorithm 2 for RPM divider
3 or higher. Set algorithm 1 for RPM dividers 0.5, 1 and 2.
