daknecht,

Q1. Can you clarify what the red 12v wire from the ACU-100 to the Seatalkng connector is for?

A1. Unlike the ACU-200 and ACU-400, the SeaTalkng communications circuitry of the ACU-100 and ACU-150 is designed to be powered by, not be supply power to, a SeaTalkng backbone. Accordingly the red wire of the SeaTalkng spur cable which is connected to the ACU-100's and ACU-150's SeaTalkng functions to supply the ACU's communications circuitry with power.

Q2. In a standard setup would you have two different 12v power supplies to the network backbone?
A2. No. In smaller SeaTalkng networks, it is not uncommon for an ACU-200 or ACU-400 to supply power to the SeaTalkng backbone. However, it is considered to be a best practices to power the SeaTalkng backbone via a dedicated power circuit rather than from the ACU-200 or ACU-400. Accordingly, the ACU-200 and ACU-400 are fitted with a SeaTalkng power switch. This switch will be positioned in the OFF position when the SeaTalkng backbone will be powered a dedicated power circuit rather than from the ACU-200 or ACU-400.
