Display
The display is not a standard part of the FX80 delivery. This is a commercial item that can be purchased locally.
A display is a required part of the FX80 Catch monitoring system. For best readability, the display must be protected from glare and have the correct height and angle.
Any commercial display can be used with the FX80 Catch monitoring system, provided that the display meets the minimum requirements. The chosen display must be designed for maritime use, and it must meet the minimum performance specifications. You must also make sure that the chosen display supports the video formats provided by the Processor Unit.
We suggest that you purchase a large high-resolution display.
Kongsberg Maritime may provide a suitable display. Consult your local dealer or agent for more information.
TipMany computers have two video ports. Many users prefer to use two displays with the Processor Unit. This can be a practical solution. One display is then set up to monitor the video feed, while the other is used to operate the trawl sonar.
The presentation on the second display is controlled using the operating system features on the Processor Unit.
Third-wire trawl cable
The third-wire trawl cable is not part of the Simrad FX80 delivery. It must be provided by the installation shipyard or the client.
The third-wire trawl cable is chosen for maximum mechanical strength, durability and minimum attenuation of the signals. Cables
in common use are coaxial with breaking points of 1500 and 6000 kg.
The quality of the trawl cable is important for the overall Simrad FX80 performance. The lower the quality of the trawl cable, the lower the quality of the video that can be received and the higher the chance
of trawl sonar data loss.
ImportantYour third-wire installation must follow the best practices for EMC compatibility to minimize electromagnetic interference
and ensure optimal performance of the FX80 system.
Winch system
The cable winch is not a part of the Simrad FX80 delivery. It must be provided by the installation shipyard or the client.
The chosen winch must offer a high-quality slip ring for the electrical interface between the Bridge Control Unit and the
Communication Hub in the Trawl Unit.
Cable winches are delivered in different types and with different capacities: low-pressure hydraulic, high-pressure hydraulic,
and electrically driven.
The choice of winch depends on prevailing conditions, the type and length of cable, and the available source of power. Most
types operate automatically — the cable is pulled out, kept tight during towing, and hauled in together with the trawl. The
control of the winch is done remotely from the bridge.
Any commercially available pulley block may be used to properly align the cable onto the winch. A snatch block has the advantage
that it may be installed without having to thread the cable through it. A unit with two movable steering arms (one on each
side of the pulley) is recommended to prevent the cable from coming off the pulley and causing damage to the cable.
