Yes they can be connected by ethernet cord. I have a buddy that just did this with a HDS5 and a 520 or 522. I believe all he can share is sonar & waypoints. He is only able to see one sonar picture at a time, meaning both units will show the same sonar/transducer image and you will have to select or change between the two sonars if you want to view the other image. Hope this made sense. Good Luck.
Guys, My understanding is that an ethernet cable between a non-HDS and an HDS unit will only allow for sonar data to be exchanged. For waypoints etc, I believe one needs a NMEA network established. Can anyone confirm if that is correct?
