Wiring Additional nMEA 0183 Devices
The NMEA 0183 data cable included with the GPSMAP 4000/5000 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 4000/5000 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 4000/5000 series
chartplotter, see the section on advanced NMEA 0183 wiring

notes:
• If the NMEA 0183-compliant device has only one receiving wire (no A, B, +, or -), leave the pink wire unconnected.
• If the NMEA 0183-compliant device has only one transmitting wire (no A, B, +, or -), connect the orange/white wire to ground.
• Consult the installation instructions of your NMEA 0183-compliant device to identify the Transmit A(+) and B(-) wires and Receive A(+)
and B(-) wires.
• Use 28 AWG, shielded, twisted-pair wiring for extended runs of wire.
• Solder all connections and seal them with heat-shrink tubing.
