Employing a high degree of resolution and field of view the diver can opt for either the Gemini 720ik or Gemini 1200ik Multibeam imaging sonars, both provide excellent range, resolution and field of view. These high specification Multibeam imaging sonars provide a diver with a high degree of confidence while working in zero visibility conditions and allow searches to be undertaken far more efficiently than using conventional search pattern techniques.
The system is designed to be used with our Gemini range of multibeam sonars, primarily the Gemini 1200ik and 720ik multibeam sonars fitted with an Inodive mounting plate. Physical Dimensions 1200ik & 720ik Please refer to the Gemini 1200ik & 720ik manuals available on our website www.tritech.co.uk full sonar specifications 0747-SOM-00004-01 Page 6 of 31...

System Connections The diagram above shows the different parts and cable connections required to the SSC before the system is powered on and deployed. If not fitting the DMD Hand Controller (untethered operation) or Diver Comms connection (tethered operation) the Blanking Plug (item 4) must be fitted. Submerging the unit and powering ON with this connection exposed will result in damage to the SSC not covered under the warranty.
Assembly & Fitting of Sonar onto Mask (Using the OTS Accessory Rails) The diagram above shows the parts required to construct and mount the sonar onto the OTS Guardian diver mask Item Part No. Description S12055 OTS Guardian Accessory Rail S12051 Spigot Assembly, 90 degree S12049...

When positioned for comfort and best view for the diver re-tighten the knurled section [4] and 2.5mm hex screw [5] to lock in place. The monocle assembly is designed to allow it to be flipped up and out of the view of the diver if required.
Any attempt to do so may result in damage to the monocle. Should you require a different monocle orientation than originally specified please contact Tritech International for advice. 0747-SOM-00004-01 Page 18 of 31...

Management of DMD Log Data Files Setup of the SSC Content Management System The Un-Tethered system is supplied with a content management cable assembly. When plugged into the sonar port on the SSC this cable enables an Ethernet connection to be setup between the SSC and the users PC or laptop.
Page 26
The illustration below shows the different items needed to connect the SSC to the your PC and how they are connected. The SubConn to Souriau adapter cable [2] allows connection between the Content Management Cable [3] and DMD Subsea Computer [1]. The system is powered by the supplied AC to 24V DC power supply [4] and te RJ45 plug on the Content Management Cable [3] into the Ethernet Network Adapter of your PC.
Page 27
Upon launching the application the content management interface will open up as shown below. The application will continually poll the Ethernet port until it detects a connection with the SSC. It will display “Status: Not Connected” until then. If the PC\Laptop Ethernet port is configured to be within the same dynamic range as that of the SSC then a connection will be made within a short period.
Setting & Synchronisation of the SSC Date & Time The SSC contains a real time clock with an on board CMOS battery back up. When connected the time and date currently set within the SSC is reported at the bottom right of the display as circled above.
Managing & downloading the stored log file content There are multiple methods for selecting, downloading and deleting recorded log file content: You can individually click on items and select to either ‘Download’ or ‘Delete’. You can select multiple items and click ‘Download Selected Items’...
