Components

The basic EM 2040P has three units: A sonar head, a

processing unit and a workstation.

The sonar head has bumpers in the corners of the face of the

transducer to protect the it if it is placed on deck, and it has

carrying handles on the sides.

The EM 2040P can be delivered with the standard processing

unit or with a splash proof (24 VDC) portable processing unit.

For completeness, data input from a motion sensor and a

positioning system is required. As is the sound speed profile

of the water column between the transducer and the bottom.

Sound speed at the transducer depth is an optional input.

Optionally, the sonar head can be delivered with mounts for

motion sensor and sound speed sensor, factory aligned for ease

of mounting.

All electronics are contained in the sonar head which is

interfaced to the processing unit via GBit Ethernet. The

processing unit also supplies 48 V power via the same cable.

Operator control, data quality inspection and data storage is

handled by the hydrographic workstation running SIS software

or by 3rd party software.
