Example screenshot of sonar imagery with a 25% compression level.
Note
Compression is applied before the software receives the sonar data and
therefore compression cannot be applied to data that has already been recorded.
Conversely, recorded data that has been compressed cannot be uncompressed.
Acquisition Speed
Acquisition speed is another mechanism available for reducing the sonar data rate and
required bandwidth. When the
Half Speed Acquisition
button is enabled (blue
background) the software will reduce the sonar image acquisition speed to approximately
half the maximum rate.
Note
Reducing the acquisition speed can also be useful if acoustic multipath is causing
false moving/transient targets to be observed in the sonar image.
Serial Inputs
Data from external serial sensors can input to the software via a Gemini Hub, the computer
COM Ports or via the additional serial ports on the Gemini unit itself. These options can be
enabled/disabled using the provided drop-down menus. See Section 5.3, “Serial Data Input”
for a detailed description of the related settings and options.
Reset to Defaults
The Reset to Defaults button, when pressed, returns the software settings to their default
values.
