Now that you have the cable down, can you create a small network with just the PB200 and something that can display the data coming out of it? In my experience it's much more likely that there is some sort of software
issue creating a conflict between devices, or causing some device to go whacko. It's guaranteed, of course, but seems the most likely.
I think you said earlier that you connected the PB200 to a PC and it worked fine? How did you connect it with the cable still in the mast? The connector on the PB200 is proprietary to Airmar, right?
I have a GH2183 on the coachroof, same connector. I terminated the end node that goes to MH & swapped the GH2183 for the PB200 then to weathercaster via a NGT1.
This is my second PB200 as the first suffered a rapid deceleration onto the deck
. After, it worked ok for a time, but developed an intermittent to permanent fault. (I dropped it installing, rather. I didn't check a crew members knot
on the tool bag and it came undone)
But the point being, it worked fine for months with this cable. No conflicts, or network errors even though a connector between the two PCB's had de-soldered itself from the board from the fall.
The replacement PB200 I purchased was a nib -old stock.
At nav table
* 1x Triton
* 1x power node
* 1x T for NGT1
* 2x dst800 triducers only one connected at a time. (The clean
node (An extension of Forward node)
* End of backbone, terminated in cable, pin 5 removed from
angle sensor N2K
*1x auto pilot
*1x GH2183 rate compass
*1x Triton Stb daisy chained to AP remote
*1x Triton Port
*Another power node
* Oh f@#k it just occurred to me that I may not have set the
the new PB200 to "0 Hz" for All nav and compass
that I think it matters unduly, as it always took the standalone
as default and ignored the PB200 of everything except wind
How vacant not to consider at least.
Thanks TW, for the mind jog.
Love your adventures.
BTW I have a PB200 6m cable (unterminated) and the resistance from CanL & CanH to ground is "overload", not M ohms.
