New equipment and integration of existing

Lazybones,

Q1. Is it correct to assume that the Seatalk side of the cable end of the Seatalk to Seatalk NG Cable is the standard "Screen Yellow Red" 3 wire cable?
A1. Yes.

Q2. We understand that power should not be supplied from both sides, Seatalk and Seatalk NG. We are planning to provide power to the Seatalk NG backbone via a separate Spur and power cable. We would then splice into the "Screen and Yellow" wire from the working Seatalk cable and connect it to the Seatalk side of the Seatalk to Seatalk NG adapter cable leaving out the red 12v+ wire. In this way, both Seatalk and Seatalk NG will have power and will not be connected to each other. Is this correct?
A2. This is not correct and may cause a ground loop condition. The SeaTalk bus should be powered by the SeaTalkng backbone via the SeaTalk to SeaTalkng Convert(s). Please click here to view a FAQ addressing this subject.
