Function

The console switch UserCenter 2/4 from G&D makes possible the operation of a server from 2 or 4 consoles (keyboard, video and mouse).

Keyboard/mouse access to the server occurs virtually simultaneously. If work is being done on a server from one console, then it is blocked for all other users. Access is only opened up again after the respective user no longer actively accesses a server. The screen content is displayed simultaneously on all connected monitors. This way it is ensured that the identical information is available to different consoles. By means of the hold function, with concurrent dark switching of the inactive console if necessary, operation can be assigned to an active console for a prolonged time period.

The devices work with total keyboard/mouse emulation for all channels and ensure error-free booting of a server, as well as the stable operation of all connected consoles. Additional consoles can also be hooked up during ongoing operations (hot-plug).

Device features

Acting as a hardware switch, it only accesses the standard keyboard/video/mouse interfaces
Does not require any software installation
Available in desktop and 19" versions
Is made with an aluminium housing for the highest degree of ruggedness
Complete combinability with all G&D products

Operational features

Switching between consoles takes place automatically by keystroke or mouse movement of the next user
Choice of operation with either PC or Sun keyboard (optional)
Hold function (see CATVision)

Technical features

Video resolution 1600 x 1200 > 85 Hz
Video bandwidth up to 250 MHz
Permanent keyboard/mouse emulation
Complete support for Sun and Reuters dealing keyboards on the console side (optional)
Support for other computer platforms such as SGI, Sun, HP, IBM RS/6000 (in part using converters)

Utilisation

Utilisation of the UserCenter occurs if 2 to 4 operator stations all have to access the same data on a server. Applications of this type can be found, for example, in trading rooms of financial services providers (sharing of services).
That way, information that is not constantly being processed by a dealer, can be made alternatively visible and processable for numerous other dealers.

Another deployment purpose is the creation of clusters with CC4/CC8 in order to increase the simultaneous user/console access to up to 64.

But certainly you know much better where you could utilise the UserCenter 2/4 in order to reduce your ongoing costs through information sharing and to employ your servers more economically.

Convince yourself of the high functionality and combinability of these devices!

Installation

Hooking up the console is surprisingly easy: Insert the keyboard, video, and mouse connectors in the intended interfaces - and that's it.

If you use a different interface other than the PS/2 that's not a problem. Just order a corresponding adapter.

Mixed operation, for instance PS/2 and Sun, is also possible of course. They are well thought-out, right from the start!

Connection to the computer is done on the back side of the device. The computer interfaces for keyboard, video and mouse are connected by the G&D standard cable that is attached to the switch.

Different lengths are no problem. Along with the standard length of 2 metres, there are also lengths of 4, 6 and 9 metres available, or - for greater distances - active extenders.
