I have a TZ14/DFF1/B164 w/ an FI504 on the network for use as a Depth repeater. The B164 performance in shallow water is suboptimal. I would like to add a smart sensor (either through hull or in hull) to read depth in shallow water (less than 20f on the ICW). Do I need to remove the FI504 from the network and set it up w/ the smart sensor as a stand alone or can I plug the smart sensor into the second NMEA 2000 port and leave the FI504 on the network? Does this even make sense? Thanks in advance.
