Hey folks I need some help.  Just purchased a new gps and wish to feed a radio, sounder, laptop and autopilot.  Is there something I should place between the gps and the other items to make the feed work properly.  Thanks for the help  Ken  Family Fun  Alaska

One NMEA-0183 output should be able to feed at least four inputs, so
you should have no problems just wiring everything in parallel.

If you will want the computer to feed the autopilot as well, you will
need a switch on the autopilot input to select either GPS direct, or
computer.

There is a wiring diagram for my NMEA-0183 installation on the "wiring
diagrams" page of my GPS site listed below that might be useful.(the
server seems to be down at the moment).

Does anyone have experience connecting a Raymarine 215 to a Garmin GPS 12XL
or GPS Map 60?

The Raymarine won't recognize the NMEA output from either unit.  I do have
an output signal from the GPS units and have the ground connections done.

Tried contacting Raymarine tech support but they have not responded.

Did you ground the purple (NMEA - ) wire on the Ray 215?

I had a problem with a Ray54 VHF, where the NMEA input optocoupler
apparently failed, so it wouldn't accept any data. If you measure the
resistance (both polarities) between the radio's NMEA input wires, you
should see some resistance in one polarity. If it appears open circuit
both ways, the input circuit is bad, and you'll have to send the radio
back to Raymarine for repair or replacement.

Be aware that attempting to drive multiple receiving devices with a
single GPS may be the cause of some hard to diagnose or fix error
conditions.

There are two issues. First that you may damage the transmitter circuit
in the GPS that sends the output NEMA strings. Second, that you may have
errors in the receiving devices, that may be difficult or impossible to
track down or isolate. Any of these may be the source of much aggravation.

I have seen exactly this sort of thing on some boats, even recently. I
would be vary wary of assuming that the documentation that specifies how
many devices can be driven by a particular GPS or whatever; should be
relied upon. Quite frankly, I would prefer for my own uses to limit one
GPS to one receiving device and if multiples are needed to get a black
box that supports one input and multiple outputs, preferably with
optical isolation.
