ArcSystem Navis 100 fixtures use RJ45 connections for power and data. Up to four can be daisy chained using the in and thru ports on the fixtures. The cable can be any category-type cable, but it must use a minimum of 23AWG conductors. Most CatV and CatVe cable does not meet this requirement, so you may need to use CatVI or better cable. The maximum cable length for a single run of Navis 100 fixtures is 100M (328ft).
