NOTE: Some Airmar and previously installed Humminbird transducers may require an
adapter cable to connect to the Black Box Sonar. For more information, visit our Web site
at humminbird.com or Airmar's Web site at airmartechnology.com.
1. See the table below to determine the port connection(s) for your transducer type(s) and Black
Box Sonar model.

Humminbird Side Imaging®
or Down Imaging®*
Airmar CHIRP**
*MEGA Imaging™ transducers can be connected to the Black Box Sonar, but MEGA Imaging frequencies
are not supported.
**The Airmar CHIRP transducer requires an adapter cable to connect to the Black Box Sonar. See the
instructions in the next section to connect the adapter cable and CHIRP transducer cable to the Black

Connect the CHIRP Transducer Adapter Cable (SM 3000 only)
If you plan to connect an Airmar CHIRP transducer, use the following instructions to connect it to the
CHIRP adapter cable (included with the SM 3000). Also, see the installation guide included with the
Airmar CHIRP transducer.
WARNING! Turn off power for all related equipment before you start the installation.
1. Turn off the power for the Humminbird control head and each connected accessory.
2. See the installation guide included with the Airmar CHIRP transducer to confirm the wiring and
that the bare wire colors match those shown in the following table.
WARNING! Your CHIRP transducer may have different wiring. It is important to refer to the
guide included with your transducer to confirm the wiring and cable connections.
3. Connect the adapter cable wires to the CHIRP transducer cable wires as shown in the following
table. Tape or apply heat-shrink insulation to each connection to prevent shorting the wiring.
NOTE: To protect the wire connections, use a junction or break-out box (separate purchase
required).
