NISE 3900E Processor Unit

A dedicated maritime computer is provided with our sonar and echo sounder systems. We refer to this computer as the Processor Unit.

The Processor Unit is a rugged and powerful computer. It is designed for long life in a demanding maritime environment. The Processor Unit contains the operational software, and offers the user interface that allows you to control the sonar or echo sounder system. Furthermore, it offers a number of serial and Ethernet lines for communication with external devices. The Processor Unit is normally mounted on the bridge.

The NISE 3900E Processor Unit operates on +9 to 30 VDC. A power supply is required if unit needs to work from an AC supply.

NOTE: The Processor Unit does not contain any fans. It will be very warm, even during normal operation. This is by design. Airflow around the unit will significantly increase the effect of the heat sinks and thereby also the lifetime of the unit.
