It has two transmit and two receive wires. Would this work? My VHF is 9 years old, and compliant with the NMEA 0183 v.

My plan is to install it at the Teensy Serial1 (pin 0 and 1), and then connect my VHF to the MAX490. I have bought a MAX490 RS422 interface (which I haven't received yet). The thing is, that I wish the programme to output the NMEA 0183 sentence directly to my VHF, and not to a PC (via USB). It is way more complex than anything I have worked with previously. I downloaded the "NMEA2000ToNMEA0183" and tried to figure out the programme. Therefore I wish to make a NMEA 2000 to NMEA 0183 gateway, and thereby transmit positioning data to the VHF.
I wish to replace the old chartplotter, and the new one I wish to buy is only NMEA 2000 compatible. The VHF (with DSC) is not NMEA 2000 compatible, and needs positioning data for the DSC to work properly. All my sensors (wind, depth, log, water temp etc.) are attached to the NMEA 2000 network, but my VHF is wired to the chartplotters NMEA 0183 output. On my boat I already have a NMEA 2000 network, as well as an old chartplotter with NMEA 2000 and NMEA 0183 interface. I have several projects coming, but I will take one at a time, and first move on when my first project is working. Nevertheless I just bought a Teensy 3.2, and tried some smaller tutorials, and made an old DS18B20 temp sensor I had lying work on the Teensy. I have previously done some smaller projects on Arduino Uno, but nothing close to the projects described in this thread. My kudos to everyone who has contributed (especially Timo).
I have been following this thread for quite some time, and find it astonishing what has been accomplished.
