Quick Start
Step 1: Decide how you will connect the Omniscan 450 to the network and provide power. See the Electrical Connection section.
Step 3: Start SonarView and click "Device Discovery." You should see a screen like this:
Step 4: Click "Connect" and you should get to this screen:
Step 7: Click Start. The device will start pinging. Manually rotate the Omniscan 450 (or the vehicle it is mounted on) and you should see the vehicle icon and "beam" rotate on SonarView. It should look something like this.
QGroundControl
If using QGroundControl, it needs to be configured to allow the vehicle to control message rates.
Step 1: Click the "Q" button in the top left, then click "Application Settings".
Click "Mavlink" on the left side, then enable "All Streams Controlled By Vehicle Settings". Restart QGroundControl now.
Step 2: Increase Ardusub message rates. In QGroundControl, click the "Q" icon in the top left and select "Vehicle Setup".
On the left side, select "Parameters". In the search box, type "sr0". Set SR0_POSITION and SR0_EXTRA1 to 50hz. If necessary, use "Force save" to set these values. Reboot the vehicle now.
Using Multiple Omniscans
Side scan applications often use a pair of Omniscan 450 SS devices to scan both sides in one vehicle pass. Dual devices are also great for utilizing Omniscan's Doppler Motion Tracking capability.
Don't leave the Omniscan 450 pinging for long periods of time when out of the water. If you do, the transmit transducer will heat up gradually, and could be damaged. Several minutes at a time should be fine.
If you've gotten to this point successfully, all is well and you may proceed to the water!
