Connecting to the GPS Receiver

Use the instructions in this section to connect the Humminbird GPS Receiver to the Y-Cable.

1. Turn off the power for the SOLIX or ONIX control head and each accessory.
   WARNING! Turn off power for all related equipment before you start the installation.

2. See the installation guide included with your GPS Receiver to install it on your boat. Make sure the cable is long enough to accommodate the planned route to the control head. See the GPS Receiver installation guide for details.

3. Connect the GPS Receiver connector to the connector on the Y-Cable.

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.
