NOTE: Product specifications and features are subject to change without notice.

Connecting the NMEA 0183 Accessories to the Y-Cable

Each 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.

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. 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.

3. Choose one set of bare wires on the Y-Cable (Serial #1 or Serial #2).

4. 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.
   RS-422 Dual NMEA Y-Cable (NMEA 0183)| RS-422 Accessory Data Cable (NMEA 0183)
   ---|---
   Orange: Transmit A(+)| Receive A(+)
   Blue: Transmit B(–)| Receive B(–)
   Yellow: Receive A(+)| Transmit A(+)
   Brown: Receive B(–)| Transmit B(–)
   Black: Ground| Ground
   Bare: Drain| Drain

NOTE: Whether connecting to Serial #1 (solid wires) or Serial #2 (striped wires), the connection information is the same for each set.
If the accessory data cable has a different set of wires, you may use the following optional wiring chart:

RS-422 Dual NMEA Y-Cable (NMEA 0183)| RS-232 Accessory Data Cable (NMEA 0183)
---|---
Orange: Transmit A(+)| Receive A(+)
Blue: Transmit B(–)| Ground
Yellow: Receive A(+)| Transmit A(+)
Brown: Receive B(–)| Ground
Black: Ground| Ground
Bare: Drain| Ground
5. If the Accessory Data Cable does not include a drain wire, tape or apply heat-shrink insulation to the Y-Cable drain wire. 6. Repeat Steps 2 through 5 for the second accessory.

Routing the Cable

1. Route the Y-Cable to the control head.
2. Insert the Y-Cable connector into the NMEA 0183 port on the control head. 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 manuals to connect each accessory to a power source.

Setting the Baud Rate

The baud rate on the SOLIX and ONIX NMEA 0183 ports defaults to Auto. To select a specific baud rate, use the following instructions.

1. From the Home screen, select Settings.
2. Select Network > NMEA 0183 (1) or NMEA 0183 (2) > Baud Rate.
3. Select a Baud Rate. Tap, or press the ENTER key, to confirm the selection.
