Dual PC system diagram

All deliveries prior to January 2010 were made with a dual PC system.

The systems units are typically installed on the bridge and in a sonar room. The main communication line between the bridge units and the Transceiver Unit in the sonar room is a single Ethernet cable.

The Simrad SX90 Fish Finding Sonar (in its dual PC configuration) comprises the following units:


  1. Processor Unit
  2. Beamformer Unit
  3. Display Unit
  4. Operating Panel
  5. Interface Unit
  6. Transceiver Unit
  7. Motor Control Unit
  8. Hull Unit
  9. Transducer

In a typical installation, only the display and the operating panel are visible, as the computers and the interface unit are mounted in suitable cabinets or inside consoles.
