Page 9: Introduction
In this mode it is possible to measure the 3D relationship between two points within the volume. In 2D mode the Eclipse sonar provides a high update rate which is used to provide display outputs that can be composed of a number of different sonar images, providing better display resolution and filter options such as persistence and movement detection. -
Page 10: Installation
3. Installation 3.1. Cable Specification The Eclipse system is supplied with two cables, both of which are terminated at one end with a Teledyne Impulse MHDG 3#16 5#20 connector. The 5m cable has bare ends for termination/splicing into the vehicle wiring. The 10m cable is terminated with a Souriau connector which mates to the bench PSU and can be used for testing the Eclipse independent of the vehicle wiring and power supply. -
Page 11: Bench Power Supply
INDOOR USE ONLY and should not be placed in a position where it could get wet. During installation and testing of the Eclipse it is possible to use the included PSU to provide both power and Ethernet connection to the Eclipse. -
Page 12: Connector Maintenance Guidelines
Installation Eclipse 3D Imaging Sonar 3.3. Connector Maintenance Guidelines Mating surfaces should be lubricated with 3M Silicone Spray or equivalent, DO NOT GREASE. Connectors must be lubricated on a regular basis. Lubricate O-rings with Dow Corning #111 Valve Lubricant or equivalent. O-rings can be seriously degraded if exposed to direct sunlight or high ozone levels for extended periods of time. -
Page 13: Reference Point
Eclipse 3D Imaging Sonar 3.5. Reference Point The reference point for the Eclipse sonar head is taken as being level with the front face, at a point along the short edge closest to the connectors as shown below. The offsets of the individual transducer arrays are contained within the software. -
Page 14: Surface Equipment
Installation Eclipse 3D Imaging Sonar The Eclipse is supplied with a number of insulating washers and fixings. These fixings insulate the sonar from its mounting and are required if the sonar is to be mounted to a non-aluminium frame. Caution... - Page 15 Power The Eclipse SPU is turned on using a button located behind the lockable front panel. If this does not work it may also be necessary to turn the switch on the rear to the 1 position.

Page 19: Keyboard Shortcuts
Operation Eclipse 3D Imaging Sonar Note Occasionally when the Eclipse software is first started the sonar head will not communicate due to network issues. If restarting the software does not resolve the problem the physical connection should be checked. 4.3. Keyboard Shortcuts A number of keyboard shortcuts are available for commonly used activities. -
Page 20: Gain
4.4.1. Gain 0 to 100% Gain is the amount of amplification applied to the sonar signal at the Eclipse sonar head. Increasing the gain will show targets of lower strength but will also increase the amount of noise and interference seen by the sonar. -
Page 21: Palette
(see Section 4.7, “Advanced Controls”). If no depth data is present then anything above the centre of the Eclipse is considered to be negative and anything below it is positive so the Start should be set to a negative number and the End set to a positive number. -

Operation Eclipse 3D Imaging Sonar Medium 2° step. Fine 1°step, slowest, most detailed. 4.4.5. Use Depths Depth Palette Intensity Palette When Use Depths is enabled the When Use Depths is not enabled the Depth Palette is used to show the Intensity Palette is used to different depths in different colours. -
Page 23: Show Grid
Operation Eclipse 3D Imaging Sonar Note The system will slow down if a very large number of points are displayed, so do not set the threshold too low when working at long ranges or when lots of targets or background noise is present in the sonar image. -
Page 24: Measurements
Operation Eclipse 3D Imaging Sonar When the mouse cursor is in the display area, the cursor display will show the cursor position relative to the Reference Point in metres or feet, depending on the unit type selected. 4.4.10. Measurements To make a a measurement, right-click with the mouse anywhere in the display area and select Measure from the pop-up menu. -
Page 25: Search Mode
ROV to be piloted using the screen. 4.5.1. Search Mode Normally the Eclipse transmits a thin 1.5° by 120° beam which is useful for: • Measurements between vertical targets are required. • Only a small part of the total image is of interest. -
Page 26: Palette
Operation Eclipse 3D Imaging Sonar 4.5.2. Palette There is no depth information on the 2D display so the data is displayed using the Intensity Palette. Clicking on the palette bar opens the palette selector. 4.5.3. Invert Display (Up/Down) The Invert Display (Up/Down) button, when clicked, inverts the image displayed by the software. -
Page 27: Filter Selector
4.5.8. Gain 0 to 100% Gain is the amount of amplification applied to the sonar signal at the Eclipse sonar head. Increasing the gain will show targets of lower strength but will also increase the amount of noise and interference seen by the sonar. -
Page 28: Cursor Display
Operation Eclipse 3D Imaging Sonar rates due to the time taken for the sonar pulse to return from the furthest range. Short ranges will have faster update rates. 4.5.10. Cursor Display When the mouse cursor is in the display area the cursor display will show the cursor position relative to the Reference Point in metres and degrees. -
Page 29: Recording (Logging) Sonar Data
Operation Eclipse 3D Imaging Sonar 4.6.1. Recording (Logging) Sonar Data Sonar data can be logged at any point by pressing the Record button on the toolbar. Data is saved as a compressed sonar image that can be replayed at a later date. -
Page 30: Capture Screen
Within the advanced options area, there are five separate tabs, each containing setup options for different parts of the Eclipse system. The tabs can be opened or closed by clicking on the white arrow on the left hand side of the tab. - Page 31 Half Speed Acquisition Normally the Eclipse system tries to fire the sonar continuously with little or no delay between pings. This buttons slows the sonar ping rate to 50% of the maximum rate, reducing the amount of data that is sent by the Eclipse sonar head.
- Page 32 This allows the units of measurement to be selected. Available options are Metric and Imperial. System Information This displays the version information for the Eclipse (SPU). If there is ever a requirement to contact Tritech International Ltd Technical Support it may be necessary to provide this information.

In preference the software should be run and the reset or load settings buttons... - Page 37 Operation Eclipse 3D Imaging Sonar 2. Delete (or rename) the C:\EclipseData\Settings\Eclipse.xml file. 3. Copy the historical settings (*.xml) file into the location C:\EclipseData \Settings and rename it to Eclipse.xml 4. Start the Eclipse software. A factory settings file is stored in the install folder (normally C:\Program Files \Tritech\Eclipse\Factory.xml).

It is possible to restrict access to the USB drives using the lock on the front panel. The Eclipse SPU is designed to be a stand-alone machine, however, if it is to be installed on a network appropriate software should be used to protect against viruses known to affect Windows computers. - Page 39 Chassis fans can be replaced with standard computer case fans. Replacement of the CPU, GPU or PSU fans will require replacement components. Please contact Tritech International Ltd for details of the support options available.

If the Eclipse is connected and powered through a vehicle Ethernet infrastructure it may be helpful to isolate it from the vehicle and connect directly to the Eclipse SPU. Use the 10m test cable and bench PSU to make a direct connection to the Eclipse. - Page 41 - if in doubt install the latest drivers from Nvidia. Drivers are available directly from the nVidia website so it may be necessary to connect the Eclipse SPU to the Internet. Make sure that the correct operating system is selected while browsing for the drivers.
