2. Overview

The ServSwitch™DT Basic II enables you to access two IBM®compatible computers

from one keyboard, monitor, and mouse. To switch between computers, simply

press the push button or enter hotkey commands from your keyboard. There is no

interface card or software to install. The ServSwitch is independent of the

computer operating system, allowing the attached computers to run different

applications.

The space-saving design enables you to connect all the cables to the back of the

ServSwitch, saving space on your desk.

The ServSwitch DT Basic II also features automatic mouse conversion, so you can

connect computers with either PS/2 or serial mouse ports and control both

computers from one PS/2 mouse. The ServSwitch automatically identifies the

mouse and switches to the proper mouse protocol.

SERVSWITCH DT BASIC II

3. Features

• Supports computers using both PS/2 and serial mice.

• Cascadable to expand system capability.

• Autoscan automatically selects computers sequentially.

• Supports Microsoft®IntelliMouse®Pro and IntelliTrackball.

• Hot-key functions for easy computer access.

• Built-in buzzer for hotkey command confirmation.

• Keyboard settings are automatically saved and restored when switching

computers.

• Operating system independent; transparent to all applications.

• True plug-and-play system configuration.

• Keyboard and mouse are hot-swappable.

• VGA video with resolutions up to 1920 x 1440.

• DDC2B compatible.

• No power supply needed.

SERVSWITCH DT BASIC II

4. Installation

Console ports connection

Turn off your computers. Connect a PS/2 mouse and a PS/2 keyboard to the

6-pin mini DIN ports of the ServSwitch DT Basic II marked with mouse and

keyboard icons. Then connect your VGA monitor cable directly to the Console

HD15 port. See Figure 4-1 below.

The monitor connected to the ServSwitch DT Basic II must be capable of

synchronizing with the computer’s video signal. If you are uncertain about the

monitor type, please consult the monitor’s user manual.

The ServSwitch uses very little power and is designed to run reliably without an

external power adapter.

Figure 4-1. Keyboard, monitor, and

mouse (console) connection.

SERVSWITCH DT BASIC II

Computer connections

Now connect the two or more computers you wish to control to the ServSwitch DT

Basic II as shown in Figure 4-2 below. Use a ServSwitch DT Basic II (3-in-1) Cable

(EHN70023-xxxx) to connect the first PC's keyboard port to the corresponding

keyboard port. Connect your computer's VGA port to the HD15 port on the

ServSwitch. Follow the same procedures for the second computer using the second

set of keyboard, monitor, and mouse ports.

If your computer uses a serial mouse, you need to connect a mouse adapter to the

computer’s mouse port as shown in Figure 4-3 below.

NOTE:

Use only the mouse adapter provided.

NOTES

1. You can't connect a serial mouse to the Console side of the ServSwitch DT Basic II.

It only works with a PS/2 mouse. The automatic mouse conversion system on the

Console side of the ServSwitch enables you to connect computers using a serial

mouse and control the computers from one PS/2 mouse.

2. Be aware that the mouse adapter can only be used on the Computer side. It will not

work on the Console side.

3. If your PC uses an AT®style keyboard, you will need an AT to PS/2 keyboard adapter

on the PC side to connect the cable to the KV7022A or the KV7024A.

5. Initial Power-up

Make sure all computers and the ServSwitch DT Basic II are powered down

during installation. After connection, simply power up the computers. This

procedure ensures the ServSwitch receives computer settings correctly when the

computer boots.

As a result, the ServSwitch will generate correct responses and allow both

computers to boot successfully without user intervention. Should you decide to

expand the system in the future or to replace failed devices, you may hot plug any

additional computer and ServSwitch (as long as they are powered off) to the

system.

6. Operations

Front-panel operation

You may switch to a different computer by pressing the front-panel push button

manually or by issuing hotkey commands. The front-panel red indicator light

changes to reflect the computer port selected. The indicator flashes while in either

Auto Scan or Manual Scan mode.

SERVSWITCH DT BASIC IISERVSWITCH DT BASIC II

Hotkey commands

The ServSwitch interprets keystrokes for hotkeys. A hotkey command is a short

keyboard sequence to select a computer, to activate computer scan, etc. A sequence

starts with two left Ctrl keystrokes followed by one or two more keystrokes. A built-

in buzzer generates a high-pitched beep for a correct hotkey command; otherwise,

one low-pitched beep sounds for an error, and the bad key sequence will not be

forwarded to the selected computer.

• Left Ctrl + left Ctrl + 1selects the computer at Port 1; left Ctrl + left Ctrl + 2

selects the computer at Port 2. Use the numbers above the letters on the keyboard,

not the keypad at the right of the keyboard.

• To start Auto Scan, which automatically scans powered-on computers one by one

at a fixed interval, press left Ctrl + left Ctrl + F1. To abort the Auto Scan mode, press

the left Ctrl key twice.

When Auto Scan detects any keyboard or mouse activity, it suspends the scanning

until activity stops; it then resumes with the next computer in sequence. The

length of the Auto Scan interval (Scan Rate) is adjustable (see below).

• Manual Scan enables you to manually switch back and forth between powered-on

computers. Press left Ctrl + left Ctrl + F2 to start Manual Scan. Press the up or down

arrows to select the previous or the next computer in sequence. Press any other key

to abort the Manual Scan.

•To adjust Scan Rate, which sets the duration before switching to the next computer

in auto scan, press left Ctrl + left Ctrl + F3.

The ServSwitch generates 1 to 4 beeps indicating a scan interval of 3, 8, 15, or 30

seconds respectively.

•To adjust keyboard typing rate (characters/sec), press left Ctrl + left Ctrl + F4,

which overrides that of BIOS and any operating system.

The ServSwitch generates 1 to 4 beeps corresponding with 10, 15, 20, and 30

characters/second respectively.
