Default Interfacing electronics again again

I would appreciate some help interfacing my JRC 1800 chartplotter/radar, Furuno 582L sonar, and Intrepid plus VHF.

Am I correct in thinking input to output? The third unit makes this tougher.

Would like to use all the features of the VHF if possible.

Do I want to work in 1.5 or 2.3?

Any help or advice will be appreciated.

I think that,s the format choices. JRC has 2 different ways to connect to their plug. One way is 1.5, and the other is 2.3.

I don't understand it either.

You want to use the highest NMEA version (1.5, 2.0, 2.1 etc) that is common to all your interfaced equipment. Higher is better but not necessarily essential.
An instrument with an NMEA input is a "listener".
If it has an NMEA output, it is a "talker".
Many of the newer instruments (like your VHF) are both listeners and talkers.
One unit talks (output) and another listens (input). The conversation between the two is NMEA sentences. These various sentences provide info regarding position (lat/lon), time, depth, etc etc.

I can simplify it a bit. Don't worry about the send/transmit/output wires on the intrepid plus cause I don't believe the JRC recognizes the DSC NMEA message, unless there's a recent update available. So that's two less wires to worry about.


JRC output/transmit to intrepid receive/input; 582 output to JRC input and 582 input/transmit to JRC input/receive....and your done. In all cases you have to connect + to + and generally all - go to ground which is usually your power ground as well.

Think has it right!! The only thing is for the furuno you will need a nmea cable if you don't already have one. They cost about 35 bucks!!!

Think Tweis

Do you mean 582 output to JRC input?


Thanks folks, I think it is beginning to sink in.

What about the 1.5 vs 2.3? JRC offers the option by changing couple of wires on the plug.

I already popped for the 35 bucks. Came in a plain wrapper, so hopefully the wire code is in the manual.

It's not in the manual. I don't remember the color codes offhand but search this forum. I know Thom posted those color codes many times.
You might also try the furuno website!!!

ruggit...You are right, I made a mistake. Wire the + outs to the + ins and then wire all the grounds together.

As far as the 1.5 and 2.3 you're on your own. If they are NMEA versions, you want 2.3. Since the change is in the plug, you may use different wires depending on which setting you choose...so read your manual or contact JRC.

When I interfaced all my electronics, I e-mailed all the manufactures (Garmin, JRC, Furuno and ICom) and they all sent back very clear and concise instructions on interfacing.

Thanks for the replies.

Hopefully I will get it all hooked up next weekend.
