I've been observing a number of high end garmin chart plotters freezing
while I'm out on
the ocean. A power cycle seams to fix it..

As for the Nema problems.. A little(salt) water inside the nema connector
chain will
screw up the communications.. Open them up, inspect them for corrosion,
clean them using
95% isopropyl alcohol, let them dry before re-assembly. Note: Add a
little silicone
grease to o-rings and threads during re-assembly.


Hi,

I wired up to see (as it should) if my computer (no plotter) would see
traffic. It didn't.

Then I did the same for my new one - and it worked fine, still no plotter,
but with the plotter leads installed.

So, I connected the plotter through the NMEA plug, and all is well.

However it was, the RS125 was not putting out the required voltage - instead
of 3.5-5V cycling, it was 2-3V cycling.

In any event, it's done, with the new one - which from a cold start (first
time, no prior connections) took 31 seconds to acquire the satellites; it
started transmitting (empty) data immediately, as seen on my hyperterminal,
then added the right coordinates - working just fine.

Still interested in having someone else' working system to put mine in to
confirm dead before I toss it (or offer it and the cable for free)...
