Appendix A. Troubleshooting
Situation
Possible cause and correction
LED does not signal after
the NMEA 2000 network
is powered 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.
First flash in 5-flashes
sequence (NMEA 2000 RX)
is RED
1. Loose connection in the data circuit.
Treat the Device connector
with a spray for cleaning electrical contacts. Plug the Device into another
connector.
2. There are problems in the NMEA 2000 network.
The network
segment is not connected to the plotter or there are missing terminators
in the network. Plug another device into the selected connector and make
sure it appears in the list of devices on the plotter.
Third flash in 5-flashes
sequence (NMEA 0183 RX)
is always RED
1. Wrong port speed.
Get sure, that Gateway port speed matches
with equipment speed (see Section VI.1).
2. Wrong wiring.
Check the connection schema (Section II.1, Figure 2)
and wire colors (Section IV.3, Table 1).
Device does not work
as expected
Record diagnostics data in TEXT format (Section VII) and apply
to technical support.
