SeaTalkNG power with ACU-400 - Best Practices

[Chuck - Raymarine - Moderator]

Keith,

There are no hard/fast rules for powering equipment and as indicated previously, how one intends to use the equipment should be taken into account. Unlike the i50/i60/i70/ST70 products, the ST60 instruments do not feature power buttons. Should it be desired to maintain power to the SeaTalkng backbone, but have the ST60 instruments OFF at times, then it would be recommended that the power lead (red) of the SeaTalk bus (not to be confused with the SeaTalkng backbone) be interfaced to a switch which may be use to open or close the SeaTalk bus power circuit.
