Airmar transducers
The wiring diagram below shows how to connect an
Airmar transducer (R309).
On some models Low frequency XDCR+ wire (yellow) can
be color blue/white.
On some transducer models temperature brown cable is
connected internally to XID GND, and there is no need to
connect bare and brown cable together.
Consult XDCR documentation for correct wiring diagram
before connecting transducer!
