SeaTalk NG power supply

Your product is supplied power via the SeaTalk NG backbone (or the NMEA 2000 backbone if applicable).

ConnectionsPowerSeaTalk NGPowerA SeaTalk NG backbone requires a single 12 V dc power supply. Power can be supplied to the SeaTalk NG backbone by one of the following methods:

  • (1) Direct connection to a 12 V dc battery using an inline 5 amp fuse.

  • Connection to a 12 V dc distribution panel using a 3 amp thermal breaker.

  • (2) Connection to the SeaTalk NG connector of an ACU-Series Autopilot Control Unit (not ACU-100 or ACU-150), or an SPX-Series course computer (not SPX-5).

  • For 24 V vessels, connection must be via a 5 amp, regulated, continuous 24 V dc to 12 V dc converter.

Note

  • (1) The battery used for starting the vessel’s engine(s) should NOT be used to power the SeaTalk NG backbone. If the SeaTalk NG backbone cannot be powered by an alternate power source, products may experience a loss of voltage when the vessel’s engine(s) are started.

  • (2) The ACU-100, ACU-150 or SPX-5 cannot be used to power the SeaTalk NG backbone.

  • The course computer SeaTalk NG connector includes a power switch that must be in the On position to provide power to the backbone.
