Installing the Interface Unit (ITU)
Once connected to the SAU, passed through the hull and tightened by a cable gland, the
transducer cable must be connected to the Interface Unit (ITU).
Location
The ITU is installed either in a dedicated sonar room or into a technical room, fairly close to
the SAU (transducer cable length = 20 m).
CAUTION: CLEARANCE SPACE NEEDED AT THE REAR OF THE ITU
Enough space shall be available at the rear of the ITU for cable connections
The connectors are located at the back of the ITU:
