Black Box KV822A, KV812A Using the PS/2 Mouse Optional, USB Plus Only, To tab through channels

SERVSWITCH™ USB AND USB PLUS

•Use {Hotkeys} + [A] to have the Switch start autoscanning (briefly displaying the video from each CPU channel in turn). You can control whether or not the Switch scans empty channels and how long it pauses at each channel; see Sections 3.3 and 3.4. To stop autoscanning, simply select a fixed channel by pressing and releasing the Switch’s front-panel pushbutton, sending a channel- selection command from the PS/2 keyboard, clicking to a higher or lower channel with the PS/2 mouse, or, if you have a Remote-Control Module, by pressing its SELECT button. For more about autoscanning, see Section 5.2.3.

•Use {Hotkeys} + [0] to select nonexistent “channel zero” in order to shut off the video output from the Switch to the shared monitor. The Switch’s front- panel display will show “0”. You can re-enable video by selecting another channel in any of the available ways.

Examples of common hotkey commands (assuming the hotkeys are [Ctrl] and [Alt]):

•To select channel 2:

Press and hold [Ctrl] and [Alt], press and release [2], release [Ctrl] and [Alt].

•To “tab through” channels:

Press and hold [Ctrl] and [Alt], press and release [Tab] (repeat as many times as necessary), release [Ctrl] and [Alt].

5.5 Using the PS/2 Mouse (Optional, USB Plus Only)

Yet another convenient way to select CPU channels on the ServSwitch USB Plus is through a three-button PS/2 type mouse, if this feature is enabled (see

Section 3.5). Simply hold down the central mouse button or “wheel” button, then click on the left-hand mouse button to switch to the next higher-numbered channel or the right-hand button to switch to the next lower-numbered channel. Keep in mind that the “next channel” will be either the next channel in sequence or the next active channel, depending on how the Switch is configured (see Section 3.3).

If you disconnect the shared PS/2 mouse from the ServSwitch USB Plus by accident during operation, the mouse will not work right when you plug it back in. To avoid having to reboot the entire system in this situation, the Switch has an automatic mouse-recovery system. With the PS/2 mouse disconnected, you can trigger the recovery system by changing the channel using the Switch’s front-panel pushbutton or the keyboard hotkeys. The ServSwitch USB Plus detects that the mouse has been disconnected and triggers the recovery system. Plug in the PS/2 mouse and the Switch will re-initialize it.
