Why Raymarine Monitor shows no data source for the sounder?
- SStacey RangelSep 5, 2025
If your Raymarine Monitor indicates no data source for the sounder, check the unit's power supply and cables. Also, check that the unit is correctly connected to a Raymarine network SeaTalkhs switch or crossover coupler. Verify the status of the Raymarine network switch and ensure that SeaTalkhs/RayNet cables are free from damage. The cause may be unit power supply fault or SeaTalkhs / RayNet network problem.
