Tritech International Gemini Operating Tips

This section describes the basic set up procedures for using the Tritech Gemini sonar with a VideoRay Pro 4. See the Tritech Gemini User Manual for additional information.

Hardware Set Up

Hardware setup for the Tritech Gemini requires the installation of the sonar on the ROV, and configuring the control panel.

ROV Connections

1. Remove the screw that holds the lower cable of the strain relief to the skid.

2. Remove the skid from the ROV by removing the screws at the bottom of the front and back main dome rings.

3. Using the skid screws removed in the last step, mount the Gemini on the bottom of the ROV.

4. Remove the 9 Pin Accessory Port Dummy Plug from the Accessory Port.

5. Install the 9 Pin connector from the Gemini into the Accessory Port.

6. Install the 9 Pin Accessory Port Dummy Plug in the back of the Gemini connector (if not already installed).

Control Panel Configuration

1. Make sure the Ethernet cable is attached from the Ethernet connector on the panel to the Ethernet connector on the computer.

2. Make sure the AUX Port Selector Switch is set to the Ethernet (down) position.

Operation

Ballast the ROV following the normal buoyancy adjustment procedures.

Depending whether you are doing a bottom search or a hull search, you may want to adjust the tilt screws (slotted holes) on the Gemini mount.

To start the Tritech Gemini software, click on the Tritech Gemini button on the VideoRay Cockpit control bar. Follow the instructions in the Tritech Gemini User Manual.

This equipment is optional and may not be included in all VideoRay Pro 4 configurations.
