The
Movement
filter highlights the changes between images and filters out static returns.
The Movement control sets how much background (i.e. non-moving data) is removed from
the image. With the Movement control set at maximum, the movement filter removes all of
the background and so the display only shows targets that are moving between images. With
the Movement control set at minimum, the movement filter retains almost all the background
(and becomes almost indistinguishable from the
Persistence
filter).
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.
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.
