Rejoining cut seatalk Ng and raynet cabiling

[davethedog]

Good morning,

Have had to cut some Raymarine seatalkNg cables and Raynet cables. What is the best way to rejoin them? Solder and then seal? A form of junction box? Connection blocks?

Thanks in advance

My ST60 sensors and repeater down below just uses small spades to make connections. In the past, other plugs similar to Raynet (Navman 5500) and ICM Navtex were wired in small junction boxes with leaf style chockblocks calmpingthe cables. I have never tries soldering.

I would use wago's in a junction box. Can't remember whether the cabling has a shield which will also need connecting and depending on the location of the cut the box may need to be metal to stop electical interference.

SeatalkNG is CANbus. The data speed is fairly modest by modern comms standards so you should be ok with any connector. Wago are good for fine cables if a bit bulky.

Raynet is Ethernet and much higher data speeds and therefore needs proper connections made. I would buy an RJ45 crimper and then use a female/female RJ45 coupler. The crimper isn't expensive. If you get what's called a pass-through one it's easier for first timers to do because the wires pass through the connector and poke out the front and trimmed when the crimp is made. You can see that you have every wire in the right order before you crimp.

Pardon our interruption...

Thanks all and just a pain I had to cut them in order to get the cockpit out for the new engine to be installed!

At risk of arousing the ire of Paul, I find 3M type gel connectors easier on the NG wires, and more waterproof. They will work as an emergency repair on Ethernet/raynet, worth carrying some for that, but making a proper joint as you describe, with the pass through pliers as you say, is the right way if it’s at all possible.

Was about to send the boys round.......
