    Connecting new VHF to old GPS questions-gctid360637

    My 2858 has a Garmin GPSMap 168 that seems to work well enough for now, but I do plan to upgrade in the future. It is NMEA 0183, as is my new Standard Horizon Matrix 2000 VHF, which also has the second station wired remote. I'm new to these NMEA connections, but here's what I understand: each unit has NMEA in, NMEA out, and ground/common. They are not the same color wires on the units, ie, red for pos, black for neg. One unit calls it ground, the other common, so I think these get connected. On the NMEA ins and outs, I'm not sure. NMEA out from one unit to the other unit's NMEA in, and vice versa? Thanks in advance...:worth

    Jeff, just remember

    Positive (+) to positive (+)

    Negative (-) to negative (-)

    Input (NEMA In) to output (NEMA Out)

    Output (NEMA Out) to input (NEMA In).

        Also check the data type on the Garmin unit. They used "garmin" data to transfer maps and courses from a pc.

        I have to change my data type to "nmea in and out" to get it to talk to the VHS. the VHS also likes the gps to be on first before it gets turned on to pick up the signal.

          jeff, on the GPSMAP 168, you will need to find the NMEA Out - Blue wire. Connect it to the Blue on the Matrix radio. Then on the Garmin, find Black ground. Connect it to NMEA Ground on the radio - Green.

          Take the time to do the reverse as well - that is, connect the radio's outputs to the GPS's inputs. Depending on which sentences are shared and the capability of each device, your GPS may show the location of an incoming DSC caller. Connect Radio Gray to GPS Brown.

          This advice is valued at 3 *WU's.

          *Work Units (WU) may be repaid with fine whisky. 1 dram = 1 WU.

          Special note - the Irish don't know what fine whisky is.

            Thanks for the quick replies!

            Mike, I have the manuals, just wasn't sure about in-to-in, or in-to-out, got it now. (Sounds kinda nasty, huh?) And insulting the Irish this close to the High Holy Day will surely get your a$$ kicked at the local pub...

              I had the manuals for the GPs connections to my Garmin 4212 and a Standard Horizon VHF. I followed the books and it didn't work. The Standard Horizon people were helpful in getting it sorted out. Before you make your connections permanent make sure everything works.

                That's a really good point. Just twisting them together will give you test you need, before going to terminal blocks or crimp connectors. And you don't hurt anything permanently if you get NEMA connections wrong.

                  A problem that I had on my connection (Icom to Lowrance) was the "baud rate". You manual for the radio should tell you which one it likes, and your GPS unit will have a switching capability. There are 2 (at least on the Lowrance)

                    Yeah, I read something about "sentences." I'll twist the wires together and give it a try. Thanks again and stay tuned...
