Simrad SH80 Processor Unit
The SH80 Processor Unit serves several functions. It allows you to control the sonar. It further 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 through the Interface Unit.
The Processor Unit is a marine computer based on the Microsoft Windows XP® 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 by Simrad to suit the sonar requirements. The computer holds a DVD player to be used for future software upgrades.
