Simrad SX90 Fish finding sonar

Processor Unit

The SX90 Processor Unit comprises a single powerful maritime computer.

Earlier versions of the SX90 sonar used a dual computer setup with a dedicated Interface Unit. Production of this configuration was stopped in the end of 2009. The current computer is the third generation used with the sonar.

Processor Unit

The Processor Unit serves several functions.

It performs the advanced signal processing required to present the information on the display, and it allows you to control the sonar. It provides the graphic presentation of the sonar modes and the images created, it holds the menu system, it communicates with the Transceiver Unit, and reads information from the peripheral units.

The Processor Unit is a marine computer using the Microsoft Windows® operating system.

It is designed for rugged use, and placed on shock absorbers. The computer is based on a commercial design, but the software and hardware has been specified and assembled specifically for Simrad to meet the sonar requirements.
