How to open
Select the Setup icon.
The icon is located under the Main menu. Select the icon one more time to close the menu.
Description
Only brief descriptions are provided. For detailed information about each function and dialog box, refer to the Reference manual or the context sensitive on-line help.
TipIf you do not need to use the menu system, you can hide it. This allows more space for the echo presentation.
Use Menu on the top bar to hide or show the menu. When the menu system is hidden, it appears temporarily on the left or right hand side of the screen if you move the cursor
to that position.

Tracking Area Use the Tracking Area function to define the size of the area that you want to detect moving objects in. An invisible area - the tracking area - is created as an acquisition area. In order for the SU90 system to find and lock on the intended target, it needs to be kept within this tracking area. If the intended target falls outside the area, the tracking can not be started.

Fishing Gear By defining the type of fishing gear you are using, the SU90 system may provide more accurate visual presentations. Use the Fishing Gear Setup dialog box to change the fishing gear properties to match your own equipment.
|
|
• |
School Select During normal operation, the detection and estimation of fish schools depends on the specie and the density of the school. The School Select function offers a selection of species. Based on your choice the SU90 system will adjust its operating parameters to achieve optimal performance.
Select School Select Setup to adjust the density for a given specie, or to create you own school parameters.
|
|
• |
Environment Environmental parameters such as salinity, sound speed and water temperature all play an important part to present accurate
echo data. Use the Environment parameters to define these values. Depending on the current sea and weather conditions, you may need to change these values frequently.
|
|
• |
Language You may prefer to use the SU90 system with the user interface in your own language. A selection of languages is provided. The Language function allows you to select the language to be used in the display presentations, menus and dialog boxes.

|
• |
Stabilization The SU90 system is provided with a built-in motion sensor to provide electronic stabilization of the sonar beams. If the sensor is malfunctioning the input can be disabled.
|
|
• |
Screen Captures While using the SU90 system you may wish to make a screen capture to save an instantaneous copy of the current presentation. You can choose either a single screen capture or a sequence with multiple screen captures.
|
|
• |
Beam Visualization With the various beams provided by the SU90 system, it may be difficult to understand the concepts. How do these beams "behave" in the water? The beam visualization feature simulates how the acoustic beams cover the seabed and the water column.

BITE (Built-In Test Equipment) The SU90 system is a computerized sonar. There are hardly any analogue circuitry, and the possibility of traditional troubleshooting is limited. In order to rectify this, a built-in software application is available to offer test and maintenance functionality. The purpose of the BITE (Built-In Test Equipment) dialog box is to allow on-line testing and verification of the hardware components in the SU90 system.

Processor The Processor page offers an overview of the parameters related to software version, operation and network.
|
|
– |
Sensors The Sensors page presents a table with all the sensors currently connected to the SU90 system. For each sensor, the status is provided.
|
|
– |
Transceiver The Transceiver page offers key information about each transceiver in use by the SU90 system.
|
|
– |
Transducer By means of the Transducer page you can check the impedance of each transducer during normal operation. Any errors are then easily detected.
|
|
– |
Noise The operational performance of the SU90 system depends on the noise conditions. It is essential that the noise signature is as low as possible.
|
|
|
• |
Export The Export page allows you to export user settings, configuration files, message logs and information mainly related to hardware and
software troubleshooting.
|
|

Installation Before you use the SU90 system you must set it up to communicate with the relevant peripherals. This includes the transducer. Use the Installation dialog box to set up all interfaces with external devices, and to set up basic parameters related to installation and operation. In most cases, you only need to do this once.
|
– |
Sensor Installation For the SU90 system to use and offer correct navigational information, one or more external sensors must be connected. Typical sensors are those providing navigational information (heading, speed or geographical position). Use the Sensor Installation page to define which external sensors your SU90 system will import information from. You must also specify which datagram formats to use. For each relevant sensor you must insert the offset values that define the its physical location relative to the vessel’s
coordinate system.
|
|
– |
Sensor Configuration With multiple sensors connected to the SU90 system, many of them will provide the same datagrams. We cannot expect that these datagrams provide the same information. The Sensor Configuration page allows you to define a datagram priority, so that the information from the "most reliable" sensor is used by the SU90 system. You can also define manual values in case a sensor is unserviceable, or not installed.
|
|
– |
I/O Setup To communicate with peripheral devices the Processor Unit offers several serial and/or Ethernet (LAN) ports. The number of communication ports depends on how your Processor Unit is set up and configured. The parameters on the I/O Setup page allow you to control the properties of each of the available communication ports. For each port, you can set up the communication parameters, and monitor the data flow.
|
|
– |
Motion Reference Unit The motion reference unit (MRU) measures the roll and pitch movements of the vessel. Some sensor models also measure heave. The information provided by the motion sensor is used by the SU90 system to stabilize the beams.
|
|
– |
Installation Parameters The Installation Parameters pages allow you to define the relationship between the physical locations of the various sensors and the transducer. All relevant system units and sensors must be defined with their physical offset values in relation to the defined Ship Origin in the vessel’s coordinate system. You will only need to define these installation parameters once.
|
|
– |
Synchronization The purpose of the Synchronization parameters is to set up the SU90 system to operate alone, or as a master or slave in a synchronized system. Synchronization is required in order to avoid interference if the SU90 system is used simultaneously with other hydroacoustic instruments within the same frequency range.
|
|
– |
Units The user interface presents many measurements. These measurements are for example related to depth, range and distance. From the Units page you control which units of measurements that are used.
|
|
– |
Operating Panel The Operating Panel must be connected to the Processor Unit using a serial port.
|
|
– |
Beam Direction The purpose of the Beam Direction function is to control the visual direction of the presentation in the Inspection views.
|
|
– |
Hull Unit Configuration A choice of hull units is available for the SU90 system. The hull units offer different physical properties and lowering depths. The hull unit must always be enabled. If you disable the hull unit, all hull unit functionality will be removed from the SU90 system.
|
|
– |
System Protection The System Protection parameters allows you to define your own warning limits for the SU90 system.
|
|
– |
Fishing Gear By defining the type of fishing gear you are using, the SU90 system may provide more accurate visual presentations.
|
|
– |
Transceiver Upgrade The Transceiver Unit is fitted with 12 transceiver boards. Transceiver board firmware upgrades may be a part of a SU90 software update. For more information, refer to the relevant software release note.
