5.2.2. Configuration Options
The
Configuration Options
allow the user to select which Gemini Sonar to use, select
the Sound Velocity to be used during image processing, modify sonar data rates, and finally
to change the network settings.
Note
In order to communicate with a Gemini Imaging sonar the software must be
set to run in Imager mode. This is done by setting the Sonar Type to “Imager”.
When changing this setting, the user will be prompted to allow the software to
restart. Once the software restarts, all Imager settings and relevant options will
be available.
Sonar Selection
The Sonar ID of the Gemini Sonar is used to determine which sonar will be used as the source
of images displayed by the software. The Sonar ID is available on the system data area of the
Advanced screen, and should be entered in the Sonar box. The number of sonars can also
be selected (up to 4) and each can have an ID. If multiple sonars are present the ID selection
field will change to allow the sonar to be positioned on the display with an offset and rotation.
The Gemini software will retrieve the IP address and Subnet Mask for the chosen Gemini
Sonar (if the sonar is visible to it) and use them to communicate with the Sonar.
Note
If the sonar is operating and
Online
has been selected then it will not be
possible to change the ID until the sonar is taken off-line.
Sound Velocity
The
Sound Velocity
controls are used to set how the Gemini obtains the sound velocity
which is used in producing the sonar image. The Gemini can either use a fixed sound velocity
(in which case the sound velocity to be used is entered in the
Fixed Velocity
box below
the sound velocity selector), or use a measured sound velocity.
