Thru-Hull Intelliducer Installation Instructions
Step 4 (NMEA 0183): Connect the Intelliducer to Power and a NMEA Connect the Intelliducer to Power and a NMEA
0183-compliant Device
Follow these instructions to connect a NMEA 0183 Thru-Hull Intelliducer. If you have a
NMEA 2000 Thru-Hull Intelliducer, see Step 4 (NMEA 2000).
The Thru-Hull NMEA 0183 Intelliducer must be connected to power. Use the diagrams to
correctly wire the Inteliducer. In the diagrams, Tx = transmit, and Rx = receive. You can
connect up to three NMEA 0183-compliant devices to receive data from one Intelliducer.

Thru-Hull NMEA 0183 Intelliducer Wired to a NMEA 0183-compliant Device
Exceptions:
If your NMEA 0183-compliant device has only one receiving wire (Rx), connect it to
the gray wire (Tx/A) from the Intelliducer, and leave the white/red wire (Tx/B) from the
Intelliducer unconnected.
Note: The orange (accessory on) wire is used when wiring the Intelliducer to a Garmin
chartplotter, or other NMEA 0183 device that has a defined accessory signal wire. If you are wiring
the Intelliducer to a device that does not have an accessory signal wire, the orange wire from the
Intelliducer should be connected to ground.
CAutIoN: If you are wiring the Intelliducer to a device that does not have an accessory
signal wire, connect the Intelliducer power wire to the ignition or install an in-line switch. The
Intelliducer can drain the battery of the boat if it is not switched.
