3.5 Access Switching
PS/2 variants of the DDXI DVI/VGA KVM Extender series offer dual access through
both Local and Remote consoles (see Figure 1). Keyboard and mouse activity
operates on a first-come, first-served basis. When the keyboard and mouse is in use
at one console, the Extender blocks access at the other until there is no keyboard or
mouse activity for a defined period – the inactivity timeout (2 seconds – the default,
or 15 seconds). A user can then gain control by any keyboard action or by pressing
left and right mouse buttons simultaneously.
The inactivity timeout period and the choice of keyboard only or mouse and keyboard
initiation is determined by jumper settings on the keyboard/mouse daughterboard
(see Appendix C: System Upgrade & Dual Access, page 48).
3.6 Private Mode
On PS/2 systems, a user at one console can lock out the other console by triggering
a ‘Private Mode’ function. This prevents the inactive console from being used, even if
the inactivity timeout period expires.
To start a Private Mode session on a console, press the ‘hot’ key command
sequence:

On the other console, to indicate that a Private Mode session has been started, the
extender system:
•
Illuminates the Num Lock, Caps Lock and Scroll Lock LEDs on the keyboard.
•
Displays a blank image on the console’s monitor.
•
Locks the keyboard and mouse.
To end the Private Mode session, press the ‘hot’ key command sequence again.
