Hi Steve,

In the meantime, our local Raymarine distributor has performed this test and
confirmed what I have found. They're taking it up with Raymarine now and
promised to keep me informed.

Meindert,
I'm sorry I cannot help, but I suggest you have definitely found a bug
with the plotter's firmware and in that light, have every
right to address this directly with Raymarine. I would assume they would
have no problem when confirming your findings to set up
the GPS test as well. They in turn will either provide a fix or a work
around for you. Please keep us informed on Raymarine's
response. Consider this a test of their customer support.

Dear Sailfriends,

A customer of mine pointed out the following problem:

A Raymarine A70 plotter connected with port 1 to a MiniPlex multiplexer
input and port 2 connected to the same multiplexer's output produces
erroneous GPS data. Instead of outputting the correct data field in the
RMC
sentence, a date of september 2009 is output.

A test where port 1 out of the A70 is directly connected to port 2 in
exhibits the same error. When the loop removed, the plotter outputs the
correct date in it's RMC sentence. Apparenly the plotter does not
tolerate
it's own data.

I would like to know if this problem also shows up when an external GPS
is
connected to the A70 plotter. Are there any A70 users "out there" who
are
willing and able to try this out?

Regards,
Meindert
