NMEA 0183

NMEA 0183 is a one-talker, one listener interface standard. This is now mainly used now for AIS to Chart plotter and Chart plotter to VHF. With supply chain issues upon us, you may need to use VHF’s that do not have a NMEA 2k connection. It’s a simple two-wire connection. Basically, a single conversation between two units. Talker A to listener B. For instance, GPS positive + out to VHF negative- in. Same for the negative out/in. Once connected you’ll need to make sure the 0183 is turned on to transmit and receive. Also on some units, if not done automatically you can select the proper Baud rate for older units
