Wiring Additional NMEA 0183 Devices The NMEA 0183 data cable included with the GPSMAP 6000/7000 series chartplotter supports the NMEA 0183 standard, which is used to wire various NMEA 0183-compliant devices, such as VHF radios, NMEA instruments, autopilots, or a computer. Basic NMEA 0183 Wiring These diagrams illustrate basic NMEA 0183 wiring used to connect your GPSMAP 6000/7000 series chartplotter to NMEA 0183-compliant devices such as an AIS or DSC device. For more-complete information on the NMEA 0183 capabilities of the GPSMAP 6000/7000 series chartplotter, see the "Advanced NMEA 0183 Wiring" section (page 13).
