There are twin goals here. One is to be able to get to the Airmar devices to update and configure them. The other will likely be getting 0183 data back out for the existing Simrad autopilot. I may end up with two gizmos, one to do the updating, the other to bridge the data.

I'm going to map out the B&G and 0183 stuff tomorrow. The old H1000 displays are coming out but there appears to be some 'entanglement' of them with the autopilot. Which may also explain an ST60 that's literally hidden inside the helm console.

I think it's taking GPS from a GP-320B connected into one MFD12, then over Ethernet to another MFD12 which is sending 0183 back out again to "some devices". Included in that 0183 data may also be some heading data, also coming into another MFD12 and Ethernet.

I've never been a big fan of trusting MFDs at bridging data. You're always at the mercy of whatever the MFD vendor thinks is "the right way" which ends up not being what the other vendors think.
