SERVSWITCH DUO™

4.2.3AUTOSCANNING: SETTING THE SCAN MODE AND PAUSE TIME

The ServSwitch Duo 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 5.7). By default, the Switch only scans those channels that have a powered-up computer connected to them. But if you need the Switch to scan all of its channels, you can send it the [L][2] or [L][4] command. (In these settings, when the Switch scans a channel that has no computer attached, or a channel whose computer is off or just not outputting video, the shared monitor will display a blank screen.) Also, if you want the Switch 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.

L1 ServSwitch Duo only scans active ports during autoscanning (default)

L2 ServSwitch Duo scans every one of its ports during autoscanning

CAUTION!

Many modern monitors are fitted with automatic power-saver relays and will automatically blank their displays after a short time if the PC they’re communicating with becomes idle. If you are using such a monitor, you should not use the Switch’s L2 or L4 setting unless you can set the monitor’s power-saver timeout to an interval longer than the Switch’s autoscan pause time (see below), 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.

L3 ServSwitch Duo powers on in autoscan mode and scans active ports only

L4 ServSwitch Duo powers on in autoscan mode and scans all ports

While autoscanning, the Switch will pause at each channel to display that channel’s video signal for the duration of the currently selected autoscan-pause time:

T1 During autoscan, the Switch pauses at each channel for 2 seconds (default)

T2 5 seconds

T3 7 seconds

T4 10 seconds

T5 15 seconds

T6 20 seconds

T7 30 seconds

T8 60 seconds

To get out of autoscan mode, simply select a fixed channel using the on-screen menu, the Switch’s SELECT button, the keyboard hotkeys, or the mouse.
