Raymarine Product LEN Matrix.

When installing a SeaTalkng backbone, it is recommended that the power insertion spur for the backbone be located at the approximate mid-point of the backbone's LEN load. Additionally and while some autopilot ACU and course computers will support powering a backbone, it is considered to be a best installation practice to power a backbone from a dedicated switched 12VDC power circuit. Please see the Product Load Equivalency Numbers (LEN) Matrix for legacy products and several current products attached to this discussion. The LEN values for currently produced Raymarine products may be found within the Specifications section of each product's respective installation guide.
