10 GPSMAP 4000/5000 Series Installation Instructions
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.
The GPSMAP 4000/5000 series unit features four ports to receive NMEA 0183 data (RX ports), and two ports to send NMEA 0183 data (TX
ports). Wire one NMEA 0183 device per RX port to send data to a 4000/5000 series unit, wire up to three NMEA 0183 devices in parallel to
each TX port to receive data from a 4000/5000 series unit.
Each RX and TX port has 2 wires, labeled A (+) and B (-) per the NMEA 0183 convention. Connect the corresponding A (+) and B (-) wires of
each port to the A (+) and B (-) wires of your NMEA 0183-compliant device. Refer to the table and wiring diagrams when wiring the 4000/5000
unit to NMEA 0183 devices.
