NMEA 0183, VERSION 1.5 WIRING CONNECTIONS
The shielded red and green wires are for a NMEA 0183, version 1.5
interface. The GlobalMap 2000 sends data to other electronic navigation
devices through the green wire and receives NMEA data through the red
wire. If the red and green wires are not used, tape their ends so that they
cannot short.
To connect a device to the mapping unit’s NMEA 0183 version 1.5 input
(send data to the GlobalMap 2000), attach a twisted pair cable from the
device’s NMEA output to the red shielded wire on the NMEA cable and the
black wire (ground) on the POWER cable. (See page 12 for wiring
diagrams.)
To connect a device to the NMEA 0183 version 1.5 output (GlobalMap
2000 sends data to another device), attach a twisted pair cable from the
other device’s NMEA 0183 input to the green wire on the NMEA cable and
the black wire on the POWER cable. See the other instrument’s manual for
more wiring instructions.
NMEA VERSION 2.0 WIRING CONNECTION
Use the four shielded red, black, white and green wires on the NMEA cable
for a NMEA 0183, version 2.0 interface. This is a shielded, balanced line
interface. Do not use the shield on these wires! Trim the shield back, away
from the splice when you attach wires from another device to the mapping
unit. The GlobalMap 2000 sends data (transmits) to another electronic
navigation device through the shielded white and green wires and receives
NMEA data through the shielded red and black wires. If the any of these
wires are not used, tape their ends so that they cannot short.
To send version 2.0 data to the GlobalMap 2000, connect the other
device’s NMEA 0183 version 2.0 output to the mapping unit’s NMEA 0183
version 2.0’s input (GlobalMap receives data) by attaching a twisted pair
cable from the other device’s NMEA output to the shielded red and black
wires on the mapping unit’s NMEA cable.
In order for the GlobalMap 2000 to send data to another device, connect
the other device’s NMEA 0183 version 2.0 input to the mapping unit’s
NMEA 0183 version 2.0’s output (GlobalMap sends data) by attaching a
twisted pair cable from the other device’s NMEA input to the shielded white
and green wires on the mapping unit’s NMEA cable.
For the GlobalMap 2000 to both send and receive NMEA 0183, version 2.0
data , see the wiring diagram at the bottom of page 13.
