Appendix А. Troubleshooting
Situation Possible causes and solutions
No LED indication after
the NMEA 2000 network is
powered on.
1. No power supply on the NMEA 2000 bus.
Check if the bus
power is supplied (an NMEA 2000 network requires a separate power
connection, it cannot be powered from a chart plotter or another device
connected to the network).
2. Loose connection in the NMEA 2000 power supply circuit.
Apply contact cleaner spray to the Device connector, and/or plug
the Device into another outlet.
The Device LED is
continuously giving 1-second
red flashes.
1. Device cannot get NMEA 2000 device address. There are more
than 252 NMEA devices already in the NMEA 2000 network. Consider
using our NMEA 2000 Bridge YDNB-07 to divide your network into
separate segments.
No three green blinks on
powering on. The Device
produces a short green LED
blink corresponding to the
every third transmission
of PGN 127508 «Battery
Status» (see IX), but it
does not appear in the list
of external devices on the
plotter. No data comes from
the Device.
1. Loose connection in the data circuit. Apply contact cleaner spray
to the Device connector, and/or plug the Device into another outlet.
2. NMEA 2000 network problems. The network segment
is not connected to the plotter, or some terminator(s) are missing
in the network. Plug another device into the selected connector, and make
sure it appears in the list of devices on the plotter.
