FCV-620 To HDS interface

[kiwihodge]

Hi all,
I have just purchased a IF-NMEA2K2 Data converter and would like to connect my FCV-620 to my HDS GEN3. ideally I would mark fish on the furuno which would then create a waypoint on the lowrance GPS. can anyone help with wiring the interface between the two units?
thanks

Waypoint from the sounder (FCV620) sends mark via TLL (Target Lat Lon) NMEA 0183 sentence. The other unit doesn't seem to support that feature, looking at their specs online.

The IF-NMEA2K2 data converter should convert the NMEA 0183 signal to NMEA200 correct? I am struggling to find a wiring diagram to mate to the HDS?
Thanks

Because TLL doesn't exist in NMEA 2000, the converter puts out a custom sentence that only Furuno units would understand. There is little chance that TLL feature will work but you do need the interface to send over GPS data to the sounder.
