1 Description
UserCenter 2 (4) allows you to operate a single computer from either 2 or four
different workplaces (monitor, keyboard, mouse).
Thus, the system makes an active contribution to reducing costs, energy and
space for additional computers and allows for more efficient use of existing
computers.
Several users are afforded comfortable, alternating access to a single
computer.
The UserCenter works in the local area and at a distance of up to 10 meters.

Active
Status
Once it has been switched on, the UserCenter initializes the connected keyboards
and mice. The User’s green status LEDs light up and the LEDs on the keyboard
flash.
At the same time, User 1’s yellow active LED lights up.
When the PC is switched on, the green PC status LED lights up and the other user’s
active LEDs are switched on.
Should one of the workstations access the computer, this station only is identified by
the yellow user active LED. The PC active LED also lights up.
Once the entry is complete, all user active LEDs light up again (each workstation can
access the computer) and the PC active LED goes out.

Guntermann & Drunck GmbH Operating Instructions UserCenter 2 (4)
Page 3
5 Operation
The changeover between the active workstations is automatic. Should a
workstation access the computer using the keyboard or the mouse, the other
workstations are blocked for the duration of this access plus the set time-out
period.
The time-out period, which is set by the manufacturer, lasts approximately 1
second. This period can, however, be extended to 90 seconds.
All of the connected monitors show the image of the connected computer at all
times.
When none of the workstations accesses the computer, the UserCenter is
released so that access can be afforded to every workstation.
5.1 Switching
The UserCenter 2(4) allows the selectable operation of the computer from 2 (4)
consoles.
In default both keyboards and mice are enabled.
As soon as at one of the consoles there is keyboard or mouse action
keyboard and mouse of the other station are disabled.
After a time out of approx 1 second where there is no action the system is
enabled again.
The time out between the switching can be adjusted to your needs (see
chapter 6.10).
Both connected monitors show simultaneously the picture of the computer.
5.2 Manual Hold function
The UserCenter 2(4) makes it possible that one of the 2 (4) consoles has
access to the computer. This prevents that the system enables the other
console after a preset time out of approx 1 second.
By pressing CTRL and PRINT the hold function is enabled.

Guntermann & Drunck GmbH Operating Instructions UserCenter 2 (4)
Page 4
The enabled hold function is indicated
•by the slowly flashing keyboard LED “Scroll Lock” at the console
where the hold function was enabled.
•by the fast flashing keyboard LED “Scroll Lock”, the disabled
ACTIVE LED LOCAL and the enabled ACTIVE LED CPU at the
console which was locked by the hold function.
The hold function will be enabled by pressing CTRL and PRINT again and the
LED SCROLL-LOCK of the keyboard will be switched off. After this the
automatic switch (as described in chapter 5.1) will be enabled again.
Notice: If you have activated the double-hotkey (see chapter 6.8) you have to
press the defined double-hotkey for activating the manual hold function.
In default the manual hold function for both consoles is released. If you
intend to lock the hold function or only release it for one console proceed
as described in chapter 6.4.
5.3 GET function
The GET-Function allows, that either the local or the remote work station can
use the computer exclusivly.
In the initial state of the GET-Function each connecetd consoles are blocked
(no keyboard and mouse action possible). Additionaly, if the dark-switching
mode has been activated (compare chapter 6.6), all monitors are dark-
switched
By triggering the keyborad-combination CTRL und PRINT, the releasing station
receives full keyboard and mouse access. Against that, the inactive console
remains blocked. The GET-function is indicated by flashing of the yellow
ACTIVE PC LED at the UserCenter2(4).
Additionally, the GET function will be indicated by:
•Flashing LED SCROLL-Lock on the keyboard, visible at the initating
console
•rapidly flashing LED SCROLL-Lock on the keyboard, which has been
blocked by the hold function
The automatic hold function will be deactivated by pushing the CTRL-Key and
PRINT-Key in combination and the SCROLL-LOCK-LED on the keyboard

dark switched again. After this the automatic changeover as described in
chapter 5.1 is enabled again.
Default: The manual hold-function is enabled. If you wish to disable the
manual hold function, proceed as described in chapter 6.5.
5.4 Dark-Switching of the screen whilst manual hold
function

PRINT-Key (similar to the hold-function)
The hold function will be deactivated by pushing the CTRL -Key and PRINT -

Default: The dark-switching is disabled. If you wish to enable the dark
switching, proceed as described in chapter 6.6.
5.5 Dark-Switching of the screen whilst GET-function
Another type of the dark switching function is the result of a combination with
the GET-function. Basiclly, the dark switching of the screen whilst GET-
function corresponds to the function as described in chapter 5.4.
In the initial state, all screens are dark switched. The initial state exists, if:
•the GET-function is enabled (see chapter 6.5)
•dark switching is enabled (see chapter 6.6)
By just one mouse or keyboard action, the screen of the active console will be
switched on. All other screens remain dark.
The GET-function will be deactivated by pressing the keys CTRL and PRINT
and the screen of all inactive consoles will be switched off again.
Default: The dark-switching is disabled. If you wish to enable the dark
switching, proceed as described in chapter 6.6.
