Autoscanning
The AdderView CATx 1000 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
•All PCs – This mode visits, in turn, each computer that is connected directly to the AdderView CATx 1000. 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.
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 1000 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.
