Garmin 4008 설치 설명서

The GPSMAP 4000/5000 series chartplotter 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 chartplotter, wire up to three NMEA 0183 devices in 

parallel to each TX port to receive data from a 4000/5000 series chartplotter.
Each RX and TX port has 2 wires, labeled A (+) and B (-) according to 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 chartplotter to NMEA 0183 devices.
Consult the installation instructions of your NMEA 0183-compliant device to identify the transfer (tX) A(+) and B(-) wires and 

Receiving (RX) A(+) and B(-) wires. Use 28 AWG, shielded, twisted-pair wiring for extended runs of wire. Solder all connections and seal the 

connection with heat-shrink tubing.

For two-way communication with a NMEA 0183 device, the ports on the GPSMAP 4000/5000 chartplotters are not linked. For example, 

if the RX port of the NMEA-compliant device is wired to TX port 1 on the GPSMAP 4000/5000, you can wire the TX port of your NMEA 

0183-compliant device to RX port 1, port 2, port 3, or port 4 on the GPSMAP 4000/5000.
The ground wires on the NMEA 0183 data cable from the GPSMAP 4000/5000 series chartplotter and your NMEA 0183-compliant device 

must both be grounded.
Approved NMEA 0183 sentences—GPBWC, GPRMC, GPGGA, GPGSA, GPGSV, GPGLL, GPBOD, GPRMB, GPRTE, GPVTG, 

GPWPL, GPXTE, and Garmin proprietary sentences—PGRME, PGRMM, and PGRMZ.
The GPSMAP 4000/5000 series chartplotter also includes support for the WPL sentence, DSC, and sonar NMEA 0183 input with support for 

the DPT (depth) or DBT, MTW (water temperature), and VHW (water temperature, speed, and heading) sentences.
Use the Communications section of the Configure menu on the GPSMAP 4000/5000 series chartplotter to set up NMEA 0183 

communications. See the owner’s manual for details.
