I want to interface the NMEA output on my Garmin 76CSx to my KVH 103 AC sail comp. The data cable on the Garmin has the following:
Garmin wiring:
Brown - serial data out
White - serial data in
Red - power
Black - ground
Sailcomp wiring
NMEA (+) Out Green, NMEA (-) Out Orange,
NMEA (+) In Blue, NMEA (-) In Brown
Garmin Brown < -- > Blue Sailcomp 103
Garmin White < -- > NO CONNECTION (tape it)
Garmin Red < -- > Battery (+)
Garmin Black < -- > Battery ( - ) (Ground)
Brown Sailcomp 103 < --> Battery (-) (Ground)
Orange Sailcomp 103 - No Connection (Tape it)
Orange Sailcomp 103 - No Connection (Tape it)

To connect your Garmin 741sx with your Raymarine ST 4000 using NMEA 183, you will need an NMEA 0183 interface cable to connect the two devices. Here are the steps to follow:
Obtain an NMEA 0183 interface cable that has the correct connectors for your Garmin 741sx and Raymarine ST 4000.
Connect one end of the NMEA 0183 interface cable to the NMEA output of your Garmin 741sx.
Connect the other end of the NMEA 0183 interface cable to the NMEA input of your Raymarine ST 4000.
Configure your Garmin 741sx to output NMEA 0183 data. Refer to your Garmin 741sx manual for instructions on how to configure NMEA output.
Configure your Raymarine ST 4000 to receive NMEA 0183 data. Refer to your Raymarine ST 4000 manual for instructions on how to configure NMEA input.
Once both devices are configured, the data from the Garmin 741sx should be transmitted to the Raymarine ST 4000 via the NMEA 0183 interface cable.
Garmins have USB or Data connectors - or both
obviously radio needs one of those inputs.
radio must be setable for Garmin format. If NMEA only verify Garmin is set to output NMEA - some do not have that option.
Question: What are the extra wires used for on the power cable for my fishfinder?
I found this on the carmin website under questions and answers. I think your cable is ok to use according to this. -->
Answer:
Not all of the wires in the harness are required for use. To connect the unit to the power source, only the black & red wires are required (black to ground, red to positive). Here are descriptions of the other wires in the harness:
The Blue wire is used for a NMEA data out connection to another NMEA compatible device. The fish finder outputs NMEA 0183 version 3.01. The receiving device must be compatible with this format and looking for the NEMA sentences DPT, DBT, MTM, or VHW.
The Brown wire is used for a NMEA data in connection to receive data from another NMEA compatible device.
The Yellow wire is used to connect to an external buzzer or alarm to alert you to any alarms which have been set to sound on the device. The Yellow GARMIN wire connects to the negative end of the external alarm. The positive return on the alarm will connect to the red positive wire of GARMIN.
The green, white, and any other colors present have no connection purpose related to your fishfinder. The 18 Pin connector wiring harness is used by several other devices which utilize these wires.
If the device is only being connected to power & do not require a NMEA interface, PC connection, or external alarm support, only the red & black wires are required.
I'm taking this as you want to send the gps information to your C80 not receive from the C80? If this is the case the brown wire on the garmin is the nmea data out +. The Black wire is considered nmea out neg (-) of the garmin. So hook the garmin brown to the white on the raymarine. Hook the black from the garmin to the green on the raymarine. That means you are outputting lat/long info to the raymarine from the garmin.
Yes, the NMEA- output (I think you lefy uot the "-" in your questoin), anyway, the NMEA - or NMEA negative or NMEA ref is hooked to battery supply ground.
Dont forget to program the Garmin to look for 48,000 baud data.
The power cable of your 2106 acts as a data cable also. You should find additional unused wires on the cable. Locate the brown and blue wires. You will need to connect the brown wire to the "NMEA OUT +" terminal on the autopilot course computer and connect the blue wire to the "NMEA IN +" terminal on the course computer. Finally, connect the "NMEA OUT -" and the "NMEA IN -" to ground (preferably the same place that the Garmin is grounded (black wire). Be sure that the Garmin interface is set up for NMEA In / NMEA Out. That should get you going!
there is no possibility to use DGPS with 76csx... due to the fact that 76csx receivers use chipset the 'sirf star III' series and this chipsets don't allow use any RTCM data.
Is your Garmin hooked up to your engine's computer via an NMEA 2000 data cable?
The gauge option will not appear in the menu if the GPS does not recognise the data coming from your engine. (If you turn on the GPS simulator, you should see the gauges on that screen.)
There are 3 possible reasons that the gauges do not appear in the menu:
1) improper wiring between engine and gauges.
2) GPS has not been set up to receive data in the GPS's NMEA setup menu.
3) Engine has not been set up to send NMEA data.
This is a relatively new feature that only works on newer engines that are NMEA 2000 capable, such as Volvo and Evinrude Etec. The engines usually need an optional instrument package to make use of the NMEA 2000 system.
We're just scratching the surface here, please reply with any questions.
is this the correct wiring for the garmin 76csx to the sailcomp 103ac
