| Connecting the NMEA 0183 Accessory to the Bare Wires
The accessory should include a NMEA 0183 data cable with bare wires for connecting to the
Humminbird Y-Cable. Refer to the accessory's user manual for information about the data cable.
WARNING! Turn off power for all related equipment before you start the installation.
1. Use the accessory manual to locate the following wires on the Accessory Data Cable: transmit
A(+), transmit B(–), receive A(+), receive B(–), ground, and drain.
2. Connect the Y-Cable wires to the Accessory Data Cable wires as shown in the following table.
Tape or apply heat-shrink insulation to each connection to prevent shorting the wiring.

| Routing the Cable
1. Route the Y-Cable to the control head.
2. Insert the Y-Cable connector into the NMEA 0183 port. The ports are labeled, and the connector
is keyed to prevent incorrect installation.
3. Hand-tighten the screw nut to secure the connection.
4. Follow the instructions in the accessory manual to connect it to a power source.
NOTE: The baud rate on the SOLIX and ONIX NMEA 0183 ports defaults to Auto. To select a
specific baud rate, see your SOLIX or ONIX control head installation guide or operations guide.
