CHAPTER 2: Overview
2. Overview
2.1 Introduction
The 2- or 4-Port ServSwitch DT Series DVI KVM Switch allows you to control up to
two or four computers from a single IBM®console (PS/2®keyboard, PS/2 mouse,
and DVI [Digital Visual Interface] monitor). Supported mice include Microsoft®
IntelliMouse®and other mice.
Using a hotkey command sequence (see Section 4.3), you can asynchronously
switch the KVM control and the attached devices. And the ServSwitch works with
common operating systems, including Windows 98/Me/2000/XP and Windows
NT.
Setup is fast and simple, and there’s no software to configure. Its small desktop
footprint is ideal for on or under your desktop. Use either front-panel buttons on
the ServSwitch or hotkeys on your keyboard to select ports or start AutoScan. The
front-panel LEDs will light with the corresponding active port when switching
between the computers. The ServSwitch beeps to confirm that it’s in hotkey mode.
The AutoScan function allows you to automatically scan and monitor all
computers, one by one, that are connected to the ServSwitch.

CHAPTER 3: Installation
3. Installation
3.1 ServSwitch Placement
The 2- or 4-Port ServSwitch DT Series DVI KVM Switch is small, portable, and
designed to fit on a desktop. Consider the following when deciding where to place
the KVM switch:
• How long are the cables attached to your keyboard, mouse, and monitor?
• How far away are the computers from the console?
• How long are the cables you use to connect your computers to the ServSwitch?
CAUTION
Do not place cables near machines that create electrical noise such as
fluorescent lighting, air conditioning equipment, etc.
3.2 Hardware Installation
This section provides instructions for the basic hardware setup of a single
ServSwitch.
CAUTION
Before you begin, make sure that power to all the devices that you will
be connecting is turned off.
To prevent damage caused by ground potential differences, make sure
that all devices are properly grounded. If you don’t follow these
instructions, your computers and/or the ServSwitch could be damaged.

2. Connect your PS/2 keyboard and PS/2 mouse directly to the 6-pin mini-DIN
keyboard and mouse ports (labeled with keyboard and mouse symbols
according to the KV99 standard) on the back of the ServSwitch as shown in
Figure 3-1. Connect your DVI cable directly to the DVI port.
Figure 3-1. Console keyboard, mouse, and monitor connection.
NOTES
The monitor connected to the DVI-I port must be capable of
synchronizing with the computer’s video signal. If you are uncertain
about the monitor type, consult the monitor user’s manual.

3.2.2 C ONNECTING THE
C OMPUTERS
Using the all-in-one DVI cable (EHN900024P-0006 or -0010), connect a computer
to the ServSwitch. Following the KV99 standard, connect the cable’s 6-pin mini-
DIN connectors to the computer’s keyboard and mouse ports. Connect the cable’s
DVI-I connector to your computer’s DVI-I monitor port as shown in Figure 3-2.
Connect the mini-DIN and DVI-I connectors on the other end of the cable to the
ServSwitch. Follow the same procedure to connect the other computers.

4. Operation
4.1 Powering Up the System
Once all cables have been connected and all computers have been powered on,
the ServSwitch emulates mouse and keyboard signals on each port, allowing your
computer to boot normally. The ServSwitch is now ready for use.
4.2 Selecting Computers Using Front-Panel Buttons
You can instantly select any computer by pressing the port selector buttons on the
front panel. The corresponding LED will light when the port is selected.
4.3 Selecting Computers Using Keyboard Hotkey Commands
Each computer is assigned a numeric ID. To directly switch the KVM control to any
computer via a simple keyboard command sequence, do the following:
1. To invoke the hotkey mode, press the <Left-Ctrl> key twice within two
seconds. The switch will beep to indicate that it’s in hotkey mode.
2. Enter your desired switch port number (1–4). For example, if you press
<Left-Ctrl><Left-Ctrl> 2, you’ll select the computer on port 2.
Or, do the following:
1. To invoke the hotkey mode, press the <Left-Ctrl> key twice within two
seconds. The switch will beep to indicate that it’s in hotkey mode.
2. Press the <up-arrow> or <down-arrow> keys to switch to the previous or next
port, respectively.
Table 4-1 lists the hotkey commands.
