Appendix А. Troubleshooting
Situation Possible cause and actions
No built-in LED indication
after the NMEA 2000
network is powered ON.
1. No power supply on the bus.
Check if 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 Device
connector with a spray for cleaning electrical contacts. Plug Device
into another connector.
Device built-in LED flashes
every two seconds, but
Device is not displayed in the
list of external NMEA 2000
devices on the plotter
1. Loose connection in the data circuit. Treat Device connector with a
spray for cleaning electrical contacts. Plug Device into another connector.
2. NMEA 2000 physical layer issue. Network segment is
not connected to the plotter or there are missing terminators
in the network. Plug another device into selected connector and make sure
it appears in the NMEA 2000 device list on a NMEA 2000 display device
(chartplotter or instrumental display).
No sound
1. Speaker is connected incorrectly.
See section III. 3.
2. Wiring issue.
Check speaker wiring for a short or a bad contact.
3. Speaker failure. Check speaker impedance with an ohmmeter.
4. Sound volume is set to 0. Check and modify volume setting
with an external button (see Section IV) or YD:VOLUME command
(see Section V).
