Seatalk Instrument Connection Question

[Eggbert]

Thank-you for your reply. The total distance is about 20 feet, so until I can measure accurately (using a piece of cord), I thought I'd ask about an alternative hookup.

I take it the 20 foot limit is based on the availability of pre-manufactured spur cables and there doesn't appear to be any in-line connections for extending a spur cable.

Not so with the backbone cables though. So here's another possibility.... if it will work, and by that I also mean the i70s can still be used to calibrate the individual wind, depth and speed sensors.

Please take a look and advise. Thank-you.
