While you are learning to use the autopilot, it is important to
practice in calm, open sea, far from shallow water, vessels, or
other obstacles.

About the SC 110 Auto ilot
The SC 110 autopilot uses multisensor technology and operation
modes to provide steering control or any type o vessel. The
control head provides graphic and numeric readouts o the
course, heading, and rudder movement. I a wind sensor is
installed, the apparent wind will be displayed in Wind mode.
There are many available operation modes which allow you to
bow target, choose turn patterns, tack and gybe, or navigate a
route rom an optional-purchase Humminbird® Multi-Function
Display. The autopilot system requires specific optional-purchase
accessories to enable each o the operation modes. Contact our
Customer Resource Center or more in ormation.
We encourage you to read this manual care ully so that you may
understand the ull capabilities o the SC 110 autopilot.

mount hardware and extension cables or your installation.
Contact our Customer Resource Center or details.
The SC 110 Autopilot control head connects to the SCP 110 Course
Computer (CPU) so that it receives input rom the Fluxgate
Compass, Gyronav Rate Sensor, GPS receiver, and all connected
autopilot equipment.
WARNING!
The CPU and all related equipment should be
installed by a Certified Marine Electronics Technician
(CMET) or an authorized Marine Electronics Installer
(MEI). See NMEA.org for details.
1. Connecting the Control Head to the CPU
1. Turn off the power to the CPU.
2. Test route the power cable rom the CPU to the
autopilot control head.
3. Remove the CPU cover and insert the cable through
the CPU strain relie or the correct terminal, and
proceed as ollows:
•Unit 1 (TB7): Remove the terminated block rom
the TB7 Control Unit 1 connector. Insert the bare
wires o the Power/CPU cable into the terminated
block connector as shown in Inserting the Wires
into the Terminated Block.
•Unit 2 (TB8): I you are connecting a second
autopilot (optional-purchase Remote SC 110
Control Head), remove the terminated block rom
the TB8 Control Unit 2 connector. Insert the bare
wires o the Power/CPU cable into the terminated
block connector as shown in Inserting the Wires
into the Terminated Block.

4. Tighten the wire connections and slide the terminated
block back into the connector.
5. Replace the cover on the CPU.
6. Route the power cable to the control head. You will
connect the power cable to the control head in a later
step.
2. Connecting the TC 110 Joystic
(optional-purchase required)
