Mounting Setup

There are two ways to specify the physical mounting of Omniscan with respect to the vehicle. If you have a single Omniscan, you can specify the transducer angle and IMU orientation within SonarView. If you have more than one Omniscan on the vehicle, you must specify the mounting details in a config.json file.
Once you have connected to a single Omniscan with SonarView, you can find the "Mount Setup" button under the Advanced Settings section of the device controls.
Click there to open the Mounting Setup dialog. If SonarView has made a MAVLINK connection to a vehicle, the vehicle's heading sensor data will be used, and the dialog will not show the IMU mounting section.
If the Omniscan is mounted forward on the vehicle, the transducer horizontal mounting angle should be 0 degrees. Positive angles to the right, so if mounted on the starboard side it would be +90 degrees and port side would be -90 degrees. Angles are typically in the cardinal 0, +/-90, 180 directions, but any angle is valid. See the illustrations below which define the transducer directions.
If the vehicle's heading not being used you must also specify the angle of Omniscan's IMU. For the FS model the IMU is within the case, and the IMU direction is toward the end of the case where the cable comes out. For the SS version, the electronics module is independent of the transducer so the horizontal mounting angle of the electronics assembly must be specified. The IMU direction for the electronics module is defined in the image below.
These values are stored in the device, so you do not have to enter them every time. You can use the Mounting Setup dialog to check that they are correct.
Configuring the mounting angles in SonarView is done through Session Configurations. For full instructions, refer here and look at the Multiple Omniscans subpage
