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 a user interface to control the sonar or echo sounder system. Furthermore, it provides several serial and Ethernet lines for communication with external devices. The Processor Unit is usually mounted on the bridge.

(The computer exists in several versions. The photos used here may not match the exact model you have.)

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

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