Installing the Operating Panel (Mk3)
The Operating Panel offers all necessary control functions for normal operation. The Operating Panel is normally placed on the bridge near the display.
Prerequisites
You must be equipped with a standard set of tools. This tool set must comprise the normal tools for electronic and electromechanical tasks. This includes different screwdriver types, pliers, spanners, a cable stripper, a soldering iron, etc. Each tool must be provided in various sizes. We recommend that all tools are demagnetized to protect your equipment. Depending on the chosen installation method, additional tools may be required.
Context
The SU90 system supports three different operating panels. These are referred to as "Mk1", "Mk2" and "Mk3".
•  The Mk1 Operating Panel is connected to the Processor Unit with three cables. The dual interface cable provides power and serial communication. The USB interface cable is used to read the trackball movements. The Processor Unit must be fitted with a custom made interface board. A small commercial power supply is used to provide power to the Operating Panel. (The Mk1 Operating Panel is no longer provided with new sonars. This information is provided for legacy reasons.)
•  The Mk2 Operating Panel is connected to the Processor Unit using an Ethernet cable. The Operating Panel is provided with a built-in power supply.
•  The Mk3 Operating Panel is connected to the Processor Unit with a USB cable. A dedicated power supply unit is not required.
A suitable location for the Operating Panel must be chosen before the installation starts. Observe the limitations due to the cable lengths. We recommend that the Operating Panel is positioned in the same physical direction as the display, so that "up" on the operating panel is the same as "up" on the display. Experience has shown that this will make it easier to use the trackball on the operating panel when you wish to control the cursor on the display.
Procedure
1 Prepare the location and the necessary tools.
Note
To allow future maintenance, you must mount the unit with its cables and connectors available for easy access.
2 Drill and cut the panel opening as shown in drawing: 476352.
3 Mount the Operating Panel using the supplied hardware.
The necessary mounting hardware (four screws, four nut plates and four bolt covers) are supplied in the standard delivery.
a Position the four nut plates shown in the illustration.
b Use a 3 mm Allen key to fasten the four special bolts.
c Mount the bolt covers in the four corners of the Operating Panel.
4 Connect the USB cable to the Operating Panel.
Note
When you connect the cable, make sure that it is properly secured, and able to withstand the vibration and movements of the vessel.
