Connecting SeatalkNG to Simnet via DeviceNet

[mikedefieslife]

I've got a SeatalkNG to DeviceNet (male) cable. I also have a Simnet to DeviceNet Female connector.

I know you're not supposed to, but I thought since the pin outs are the same, I'd might be able to just connect these together to end up with a SeatalkNG to Simnet cable.

I'm not sure that works though, so need to find another way to hook this up.

Why can't you connect them? Keep the total cable length under 6m and no problem.

The only other option is to cut the ends off a simnet and stng cable and splice them together. Which is a much worse option if you already have plugs that fit together.

Just connecting them doesn't seem to work.

What I'm trying to do is to connect my Simrad RI10 box to the SeatalkNG network so that it can use data from my Raymarine EV1 solid state compass and heading sensor for MARPA

go into the radar install menu. you can see if the radar is getting external heading. no reason why it should not work. is the plotter currently getting heading via n2k?

I get "no heading connected to radar" despite the fact that it is and can be seen by both my autopilot (raymarine) and my MFD (simrad).

That leads to believe the problem is in the cabling from the RI10 box to the SeatalkNG 5-way splitter. As I said it's a Simnet to DeviceNet - DeviceNet to SeatalkNG connection.

The only thing I could think of is that connecting to the two DeviceNet ends, is the problem, as I've never seen or heard of it done before. But then as you say, since the pinouts are the same, it should work better than cutting off the ends and making a cable.
