[C320-list] Data IN ... Data OUT Garmin to AutoHelmST4000Plus

   How do I interface another manufacturer's GPS to my Raymarine autopilot?
  Question   I have another manufacturer's GPS unit connected to my
Raymarine autopilot by NMEA. When I set a "GOTO" waypoint on the GPS and
call up the use of the "Auto...Track" instruction on the autopilot, the
autopilot comes back and says "NO Data Available". Could you suggest what I
should look at first?    Answer   All of our current autopilots are directly
NMEA compatible. The autopilot has a NMEA IN (+)and a NMEA IN (-). Some
other manufacturers' GPS units have a slightly different NMEA wiring
configuration with a NMEA IN (+), NMEA OUT (+), and a single ground wire
which serves as the negative for NMEA IN, NMEA OUT, and Power.

Connect the GPS units NMEA OUT (+) to the Raymarine pilot's NMEA IN (+).
Then, to connect negative side, run a line from the Raymarine NMEA IN (-) to
the GPS ground wire, or to ground.

Some GPS units have a configurable NMEA Output. Make sure that it is set to
output 4800 baud, NMEA 0183, and if selectable version 1.5 or higher.
        How do I connect my handheld GPS to a ST4000    Question    How do I
connect my NMEA 0183 compatible hand held GPS to a ST4000 control head
Answer

The handheld GPS should have a wire that is marked NMEA Data Out.  This wire
connects to the NMEA (+) terminal on the ST4000 . Next,  if the handheld GPS
does not have a dedicated NMEA Data ground wire, connect a wire from the 12
volt ground wire of the handheld GPS to the NMEA (-) terminal on the back of
the ST4000.   Do not use the "NMEA Data In" wire on the hand held GPS
