an adjustable keyboard-timeout basis.

• Displays video to all user stations

simultaneously.

• Supports temporarily private or

uninterruptible connections.

• Supports any two-button PS/2 or

serial mouse.

OVERVIEW

Do all of your users really need a dedicated computer CPU

on their desk just to look up something on your network once

or twice a day? If they can share access to data or an

application program, why buy multiple CPUs and multiple-

seat software licenses when you can get by with one of each?

If this sounds like a good idea to you, try a ServShare™

keyboard/video/mouse (KVM) switch. Users at the two, three,

or four attached “user stations” (each consisting of a monitor,

keyboard, and mouse) can take turns using the attached IBM®

PC compatible CPU (and controlling the ServShare with

keyboard commands) for as long as they want. Once a user’s

keyboard has been idle for the length of the adjustable

inactivity timeout, the ServShare releases the CPU for the

next user—first come, first served.

Normally, the ServShare handles switching automatically

while displaying the CPU’s video on all users’ monitor screens

at the same time. But you can also blank the video at other

stations for privacy, or even disable keyboard and mouse

control at other stations to avoid being interrupted by other

users while they wait for the CPU to process or download

something. (Don’t worry—if there’s a station or a user that

you don’t want to be able to do this, you can disable

keyboard commands from that station by setting DIP switches

on the ServShare.)

Connecting devices to the ServShare is a piece of cake.

You’ll run a three-in-one CPU Adapter Cable to the CPU,

and similar KVM Adapter Cables to each user station, up

to maximum CPU-to-station distances of 200 feet (61 m).

The ServShare supports VGA, SVGA, or XGA video up

to 1280 x 1024 noninterlaced, although SVGA and XGA

will require coaxial cabling. It also supports PS/2®or PC/AT®

compatible keyboards using any of the three IBM “keyboard

modes.” And the attached mice can be any two-button PS/2

or serial type by Microsoft®or Logitech™.

The front-panel LEDs of the ServShare show unit power,

which stations are receiving video, and which station is

controlling the CPU.

The ServShare also saves the Num Lock, Caps Lock, and

Scroll Lock states of the keyboards, and it instantly refreshes

their LEDs when users connect.

With the ServShare, you can set the keyboard “typematic”

(automatic key repeat) rate and delay for each keyboard.

The ServShare automatically re-enables PS/2 mice when

they’re reattached after being disconnected.
