I have a 959ci hd di on the bow with a terrova w I-PILOT Link and a 360 transducer on the bow all connected via the Ethernet as eth 5pxg. I also have a 797c2 nvb on the transom. I s doesn't appear that I can add the 797 to the Ethernet system. Is there any advantages to using the interlink hub to interlink the 797 to the 959? I was wondering if I could attach the 797 to the interlink and then attach the interlink to the Ethernet as eth 5pxg?
