The ServSwitch Wizard begins autoscanning its CPU channels (that is, briefly
displaying each channel’s video in turn) when you type in the hotkey sequence
followed by the letter “A” (see
Section 5.5 ). By default, the Wizard only scans those
channels that have a powered-up computer or cascaded switch connected to them.
But if you need the Wizard to scan all of its channels, you can send it the [L][2] or
[L][4] command. (In these settings, when the Wizard scans a channel that has no
computer or cascaded switch attached, or a channel whose attached computer or
switch is off or just not outputting video, the shared monitor will display a blank
screen.) Also, if you want the Wizard to start autoscanning as soon as it powers up,
instead of waiting for the “A” command, you can send it the [L][3] or [L][4]
command.
Please keep in mind that in cascaded systems, it isn’t possible to perform a single
autoscan of the whole cascade; you must separately scan each Wizard that has
CPUs attached to it. During a scan, when a Wizard switches to a port with a
cascaded switch attached to it, the system will display the video from whatever
channel is currently selected at the
cascaded
switch. Refer to
Section 5.10
.
L1 ServSwitch Wizard only scans active ports during autoscanning (default)
L2 ServSwitch Wizard scans every one of its ports during autoscanning
L3 ServSwitch Wizard powers on in autoscan mode and scans active ports only
L4 ServSwitch Wizard powers on in autoscan mode and scans all ports
CAUTION!
Many modern monitors are fitted with automatic power-saver relays
and will automatically blank their displays after a short time if the
computer they’re communicating with becomes idle. If you are
using such a monitor, you should not use the Wizard’s L2 or L4
setting unless you can set the monitor’s power-saver timeout to an
interval longer than the Wizard’s autoscan pause time (see the next
page), because if the monitor keeps going in and out of power-
saver mode during autoscanning, the constant switching ON and
OFF of your monitor’s relay will eventually damage your monitor.
