I've got a little package of
Raymarine networking goods. I was using these things to shoot
depth info from my ST40 to the ZeusT7. Pulled these things because I'll be putting the N2K through
hull in later this year.
Raymarine E22158, ST1 to STNG Coverter
Raymarine A06045, STNG to Devicenet / Micro-C cable
Raymarine D244, St1 3-Way Junction Block
There also looks to be an extra ST1 to ST1 cable.
$100 shipped to the US.
