Chandrella,

You are running so many things together there that it is difficult to
keep track.

Are you saying:

You will have one (1) GPS that you hope to use in two (2) locations?

And you hope to do this by have two identically wired connectors, one at
each location?

You hope that this will work effectively with your Icom?

If this is correct, yes, I do this all the time. In fact mine connects
to a data buss in any of three places, but it does have to be connected
to one for the autohelm to steer on wind because I pass that through the
Garmin (this one is a 48).

I am thinking of buying a Garmin 76csx Gps and an Icom M422 VHF. The
Icom will transfer NEMA data to and from the gps for position display
on my or another boat's gps. Use will be on a sail boat and I'd like
to be able to use the gps at both the helm and in the cabin where the
vhf radio is.

Question is, can I just common the NEMA IN/OUT data cables at both
stations between the gps and vhf? That is, simply plug the gps into
whichever location I want to use it at, by hooking the data cables
together in parallel. Of course only the 1 gps would be hooked to the
one vhf radio at whichever gps station. My concern is impedence or
stray signals possibly from the unterminated data cable.

Wold be using these data cables from Garmin. Run would only be about
10 feet between the cabin and helm station.
