Autoscanning
The AdderView CATx provides an autoscan mode that switches between
the connected computers in sequence. This mode is useful to allow users
and administrators to sample activity among the connected machines. Three
scanning modes are provided:
•
Scan list – Only computers declared within an autoscan list will be viewed.
Computers connected to cascaded switches can be included in the autoscan
list.
•
Active PCs – Only computer ports where an active computer is detected will
be viewed. This mode avoids blank screens from being displayed and helps
to prevent the viewing monitor from entering a power-down state on every
scan cycle. Computers connected to cascaded switches will not be viewed in
this mode.
•
All PCs – This mode visits, in turn, each computer that is connected directly
to the AdderView CATx. This mode should be used with care due to the
reasons given in the warning below. Computers connected to cascaded
switches will not be viewed in this mode.
The scanning mode is a global setting and hence will be the one viewed by any
user who selects on their keyboard. Note, however, that users will
only see the scanned computers to which they have access rights. Hence, if two
users (with various access rights) simultaneously view an autoscan, they will see
differing results depending upon their respective permissions.
WARNING: Many monitors are fitted with automatic power saving
relays that switch off after a few seconds when connected to an inactive
computer. If you are using such a monitor, do not set the AdderView
CATx to the scan ‘ALL PCs’ mode. Continual switching on and off of
the monitor’s relay will eventually damage the monitor. If using such a
monitor in conjunction with the ‘Scan List’ option, ensure that all selected
computers are active.
