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.
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.
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.
