Stus-List Paws Electronics Upgrade Continues

[John Pennie via CnC-List]

Thanks again Fred.  I don’t think I’ll be able to do what I was hoping. Bellow 
is a summary from the B manual.  It’s a circa 1999 H1000 system.  I was just 
going to connect the wires and see what data is available - maybe I have a 
newer version than detailed below (don’t crush my dreams!).  All of this is a 
bit greedy - just trying to eliminate one display head from the helm.  Really 
don’t want to spend the boat dollars on a new AP and I need another project 
like a hole in the head.

Thanks.   Just knowing “RSA” is a help!  Will let you know what I find out and 
how it all goes.

John — you’ll have to check whatever documentation you can find on the B, and 
see if it: #1 — even has an NMEA0183 output; and #2 — can output the “RSA” 
(rudder sensor angle) sentence.

Usually, NMEA0183 implementation on older autopilots is limited to input of 
NMEA0183 sentences having to do with navigation to a waypoint.

If you find documentation and need some translation, let me know.

Thanks Fred.  It is a 9” plotter for that very reason.  It is connected to wind.

I’m not even thinking about steering to a waypoint - I just want a rudder angle 
display on the plotter! 

So I should not expect any input from the AP?

John — which a Series plotter have you got?  The 7” variants do NOT have 
NMEA0183 on them, which you’ll need for the B pilot.  The larger a Series 
variants do have NMEA0183 on them.

As far as the extent of talking to each other, it’s going to be a one-way 
conversation; the MFD will output bearing to a waypoint and cross-track error, 
and the pilot will steer to it when enabled.  That’s it, unless you have a wind 
instrument tied to the plotter, and the B will steer to wind angle.

Stus-List Paws Electronics Upgrade Continues

[John Pennie via CnC-List]

Just a quick update as so many folks here have been helpful in this project.  
The electronics upgrade continues and we’ve now completed the second milestone. 
 We got the new instruments in last fall (ugly project) and just today 
completed the chart plotter installation at the helm.  Hats off to Raymarine as 
this stuff really is plug and play.  We thought the hardest part would be 
running new wiring through the pedestal (and it was a bear) but that was 
nothing compared to pulling out all the old wiring.  They seemed to love wire 
ties, caulk and electrical tape and used all with abandon.  I was never overly 
pleased with the electrical and/or wiring work on my Tartan built C so 
yanking it all out was satisfying.  The built in GPS in the Ray A unit seems to 
work well so I don’t see a need for an additional GPS head. 

Next step is to resurrect the B autopilot and figure out to what extent I can 
interface it with the chart plotter.  It’s a 15 year old pilot but works well 
and I really don’t want to replace it. The B ram is a thing of beauty.  When 
we removed all the old B instruments last fall we cut the AP head off from a 
power source.  Apparently it’s not happy about that.  Will reinstall this week. 
 I really like the clean look of the helm with just the plotter so I’m hoping 
to find some other home for the AP head.  Just not sure how much control I can 
have via the plotter with just a nmea 183 interface.  Will hook it all up and 
see to what extent they talk to each other.

Hopefully the next update will be next weekend!

John
