Welcome to the Raymarine Forum Wayne,

Your diagram appears correct and as would have been advised given the equipment shown. Should you decided to add any additional devices to the SeaTalkng backbone, then it would be advised that the ACU's SeaTalkng power switch be configured to OFF and that a spur socket be installed located at the approximate mid-point of the backbone's LEN load. A SeaTalkng Power Cable to be powered by a switched 12VDC power circuit would then be connected to the spur socket located at the approximate mid-point of the backbone's LEN load.
