Omnitrack Buoy Wired/Tethered
This page will cover the basic deployment and operation of the Wired OmniTrack system with the BlueROV2.
Requirements:
Note:
This guide is written assuming that the OmniTrack system is outfitted with the MKIII ROVL. If using the MKII ROVL, the term Transponder instead refers to the transmitter, and the term Transceiver instead refers to the Receiver.

Setting up the Omni Track Buoy
Unbox OmniTrack. Be careful not to damage the ROVL Transceiver as its cable is connected to the buoy! Do not forget the included accessory package and ROVL Transponder in the packaging.
Before installing the transceiver and assembling the buoy take this chance to connect to the transceiver to preform calibrations and configuration.
Connect the end of the Omnitrack tether to the POE injector. Using the included Power adapters connect the POE injector to your computer and power.
Open SonarView and using device discovery connect to the Omnitrack.
Perform Calibrations LINK
The Omni Track should be preconfigured for use but verify and change as needed. ROVLe Configuration
Assemble the Omni Track. Assembly Directions.
For more information see our assembly video.
BlueROV2 Installation and Setup
Make sure your BlueROV is fully functional. See the Blue Robotics documentation. Verify that you are able to connect to your ROV
If using a Tracker 650 DVL along side of Omnitrack, first make sure that it is fully installed and configured in accordance with the documentation. Tracker 650 DVL Documentation
When configuring the Tracker 650 ensure that it is NOT set to send a Global Origin. Tracker 650 configuration
Mounting the Transponder to the BlueROV2.
Determine the desired mounting location for the MKIII on your vehicle. Make sure to keep in mind the DeepSide ROVL mounting considerations.
Install the transponder using the provided mount and hose clamp onto the ROV Frame. Below is an example mounting location as used during testing.
Wiring the Transponder into the BlueROV2. For more information see Blue Robotics BlueROV2 Servicing Guide
Remove Power from the ROV and completely open up primary electronics enclosure.
Route the transponder cable to the primary electronics enclosure and install the provided penetrator. Make sure surfaces are clean and lubricated as needed.
Connect the power leads to the vehicle's power distribution rails. (Red +, Black -)
Tape the serial leads (white and green wires) so they don't short together or short to exposed terminals in the ROV.
Close the enclosure.
Adjust ROV ballast as required
Verify transponder operation
Power on the vehicle
If using a MKIII ROVL lightly tap the end of the transponder listening for an audible click. If it clicks it is correctly operating
if using a MKII ROVL you should be able to hear an audible click from the transmitter once every second after it powers up and is exposed to a GPS signal.
You are done with the ROV.
Deploying the OmniTrack
Magnetometer calibration
The magnetometers are subject to variations in the Earth's magnetic field strength and to magnetic disturbances due to electrical currents and and nearby soft iron or other ferrous objects. The closer a disturbance source, the smaller it can be and still affect the north-finding. Generally, you should calibrate the magnetometers when you move the system a geographically significant distance (e.g., 50 km or more).
You should choose a location to run this calibration that is not affected by ferrous objects such as dock structures, rebar, steel boat hulls, electrical conduits, etc. It should be either the location you will be using (e.g., the boat) or an area as much like the one you will be using as possible.
Moving a Boy Scout compass around in the area you plan to use for the calibration can turn up unexpected magnetic anomalies. If the needle deflects in unexpected ways you should determine the cause and/or choose a new location.
Connect to the ROVL using Sonar View
