Default Interface a Garmin 182C,320C to a Furuno 1623 Radar

All,

I have the Garmin 182C and 320C along with a Furuno 1623. I am trying to interface all of them together, if there is a post somewhere that I may have missed please forward it over.

Anyway, I have so far been succesfull in interfacing the DSC VHF, and 182C to display information on the Furuno. I have run the blue data out wire of the 320C to the brown data in on the 182C then output the blue data out to the VHF, and Furuno. I have tried individually hooking up the 182C and 320C to seperate inputs figuring the 182C wasn't passing the depth/temperature data. However, only the 182C navigational data would display. I have received wiring schematics from both Garmin and Furuno all of which have been wired differently to no avail. Anyone experience the same problems, help?

Thanks,
Rob

Both your GPS and your fish finder will share the same (-) negative side data transfer wire, which also doubles as the power ground wire. That is not the case with the Furuno, which will (in accordance with NMEA standards) will use a seperate data negative wire. That is the one wire you didn't mention in your setup. What do you have the data input negative wire from the Furuno connected to? Just as a help, although it is not consistant through the Furuno lineup at least on most of them the wire you're looking for will be green, though it could be black.

Hey Thom,

Thanks for the reply. I have the Furuno cable 144-418 (I think) which has a number of wires out. I use the Yellow and Green for the 182C and Blue and white for the 320C. I think the Furuno yellow is connected to the Blue wire of the 182 and use the Furuno green with the black (-) on the 182. Furuno tells me the yellow and green are for the 320 however, it doesn't work but works with the 182. The Furuno blue and white are disconnected currently until I get it all figured out. Guess it would help if I had the proper schematic on the Furuno data cable.


Thanks,
Rob
