1. Specifications

KVM EXTENDER/SHARERS

2.1 General Overview

The Keyboard/Video/Mouse (KVM) Extender/Sharers let you either

control a computer from a remote keyboard, monitor, and mouse, or share

a computer between two users (not at the same time). In Shared Mode, local

or remote user control is exercised through a switch on the Host Module of

the Extender/Sharer, which is connected directly to the computer.

The KVM Extender/Sharers work with IBM®PC/XT™, AT®, or PS/2®

computers and 100% compatibles. They support Video Graphics Array

(VGA) monitors and graphics, and are compatible with both powered and

nonpowered serial mice or any serial-interface device such as a trackball or

digitizer pad. They are transparent to application software, so remote displays

are updated immediately.

Your remote setup can be located up to 150 feet (45.7 m) away from the

computer. Of course, in order to share the computer between a local and

remote setup, an additional keyboard, monitor, and mouse (if the application

software requires one) must be purchased separately.

With the regular KVM Extender/Sharer, remote video is disabled when the

unit is switched to local operation and vice versa. With the KVM Extender/

Sharer Plus, video can be active at both sites, regardless of where the input is

coming from. And with the KVM Extender/Sharer Pro, not only can video

can be active at both sites, but you can switch control from site to site by

pressing any key on an inactive keyboard.

2.2 Important Features

• Can be used in Extension or Shared Mode—either operate your

computer solely from a Remote monitor, keyboard, and mouse, or

switch control back and forth between a Remote and a Local setup.

• Shared operation—your two sets of keyboard, monitor, and mouse can

be in different rooms, in different areas, or even on different floors, up

to 150 ft. (45.7 m) away.

• Remote lockout ability—prevents two users who are sharing a computer

from different locations from entering information at the same time.

• Transparent to all software and graphics—what you see on the local

monitor is what appears on the remote monitor.

2. Introduction

CHAPTER 2: Introduction

• Supports a serial input in addition to the keyboard at the remote site—

you can remotely use not only the keyboard but also any serial mouse,

trackball, light pen, or digitizer pad that complies with the Microsoft

Mouse standard.

• VGA Extender/Sharer Plus and Pro: Both monitors can display the same

screen simultaneously.

2.4 Other Items You Might Need

You might need extra cabling and/or adapters to complete your

Extender/Sharer setup. See Figure 3-1 for where these components might

fit into your scheme.

male; allows you to plug PS/2 keyboards into Local or Remote Modules

or plug included keyboard cable from Host Modules into PS/2 CPU.

• EVNPS05-0005: VGA Video Extension Cable, 5 feet (1.5 m), to connect

Host Module or Host Module Plus to CPU’s VGA port.

to-Remote-Modules Cable), up to 150 feet (45.7 m).

CHAPTER 3: Installation

The KVM Extender/Sharer modules are simple to install; Figure 3-1

below and Figure 3-2 on the next page show typical setups.

1. Connect the video, mouse, and keyboard cables from the computer

to the appropriately labeled connectors on the Host unit.

2. Run an appropriate extension cable (see Figure 3-1 or 3-2) from the

connector on the Host module labeled “Remote” to the connector on

the Remote module labeled “HOST.” Then run the cables from the

remote monitor, keyboard, and mouse to the appropriately labeled

connectors on the Remote Module.

KVM EXTENDER/SHARERS

If you’re going to use the Extender/Sharers in Shared Mode, run an

extension cable from the Host Module to the Local Module connector

labeled “HOST.” Then run the cables from your local monitor,

keyboard, and mouse (or other serial device) to the appropriately

labeled connectors on the Local Module.

NOTE

The Local Module should be placed no farther than 6 feet (1.8 m) from the

Host Module.

With all your cabling finished, you’re ready to start using your

Extender/Sharer equipment.

NOTE

You might need specialty cables for your Extender/Sharer application.

For example, in applications with PS/2 keyboards, you’ll need three PS/2

Keyboard Adapters (FA212). And to extend the distance between your

host and remote modules to 150 feet (45.7 m) for VGA, you’ll need an

extension cable. Refer to Section 2.4 for a complete list of cables and

adapters, and to Figure 3-1 for an illustration of where they fit in a typical

Extender/Sharer application.

CHAPTER 4: Operation

Once the computer system is booted, if you’re in the Extended Mode, you’re

ready to begin working.

NOTE

In Shared Mode, always cold-boot the system from the Local setup. If

you boot from the Remote Module, the results are unpredictable.

When the computer system is booted in the Shared Mode, the local user has

the option of remaining connected to the PC or switching control to the

remote keyboard, monitor, and mouse. There’s no need to go to the Remote

Module to power up, because both the Local and the Remote Modules are

powered from the computer.

To remain connected at the local setup, you don’t have to do anything. Just

type in commands or click on icons; control remains with the local display,

keyboard, and mouse.

To switch the connection to the remote location, the local user must flip a

switch on the Local module. With the switch in the “Remote” position,

“autosensing” is enabled. This means that the local keyboard can still be used,

but when a key is pressed on the remote keyboard, the remote site is activated

and the local keyboard is locked out. Connection can be returned to the local

user at any time by simply switching the “Local-Remote” switch to the “Local”

position.

Exit all applications before you switch control between Local and Remote

setups. This is because when you switch between Local and Remote operation

while running an application, no reset or initialize commands are sent to the

new setup (the application is already running—it doesn’t know about your

second keyboard, monitor, and mouse setup). Many keyboards and mice

cannot reset or initialize themselves; they require commands from the

computer. Without those commands, the keyboard and mouse at the location

you’ve just switched to might not work. If this happens, the application will

have to be rebooted once the second setup is connected to the computer.
