Gemini Software Operation

5.2.5. Device Network Settings

VDSL Settings
The VDSL Settings drop-down allows three different settings to be applied to the VDSL
link in order to cope with different levels of electrical noise experienced by the sonar cable.
Appendix C, Setting the Gemini Device IP Address in Gemini Software describes how the
Gemini network settings can be altered to allow it to work with a desired network. Once the
head has been successfully configured it should not be necessary to change the settings
again unless moving to a different infrastructure.

5.2.6. Distance Marker

The Distance Marker provides a mechanism for measuring the distance between two
points in the Gemini data view. This is similar to the Measurement Tool but provides
additional options that allow it to be used as a more permanent measurement.
Enable the feature by clicking the Enable Distance Marker button. This will draw the
Distance Marker as a horizontal line and the Set Point as a small circle in the Gemini
data view.
For both the Distance Marker and Set Point, the corresponding colour selector may
be used to distinguish the markers from the head image. Click on each colour box to open a
colour selection dialogue. Additionally, for each marker, the Cartesian coordinate is displayed
in the Distance Marker panel. The Distance Marker line width can be set by entering a
value into the Marker Width field.
In the Gemini data view, each marker can be clicked and dragged to a new position. The
distance measurement will continuously update and reflect the distance between the two
markers.

Note
Only if difficulties are being experienced communicating with the Gemini head
should the VDSL settings be changed from Normal to one of the other values.
