So I guess the SeatalkNG five point buss is inside the pedestal pod. I have a 1’ spur cable for the P70. Makes sense what you say. That was a really helpful comment. While I have it all apart, it makes sense to get the itc5 and some more T connectors.That’s the beauty of the SeaTalkng network. You only need one backbone cable run up the pedestal guard. Connect your devices to the one backbone cable using 5 way and T connectors.
If you use the iTC5 you no longer need the transducer wires going up the pedestal. You‘re down to needing just two cables run up the p guard. Power and backbone.
ie: I have my chart plotter, two i70S displays and P70 display at the top of my pedestal guard. All are connected to the SeaTalkng network using one backbone cable run up the pedestal guard.
need an engineering degree and a circuit diagram for this!
