Introduction

Overview

The StarView SV231 is a computer switch that allows access to two IBM compatible

computers from one keyboard, mouse and monitor. Switching between computers

is as easy as pressing the push button or entering hot-key commands from your

keyboard. There is no interface card and software to install and the StarView is

independent of the computer operating system. The space-saving design enables you

to connect all the cables to the back of the SV231.

Automatic Mouse Conversion

The StarView Switch enables you to connect computers with PS/2 or serial mouse ports

(using adapters supplied with each SV231), and control both computers from one PS/2

mouse. The StarView automatically identies the mouse and switches to proper mouse

protocol.

Instruction Manual

Installation

Device Connection

Turn your computers o. Connect a PS/2 keyboard to the mini-DIN-6 port with a

KEYBOARD icon and a PS/2 mouse to the mini-DIN-6 port MOUSE icon . Then connect

your VGA monitor cable directly to the HD-DB- 15 port of CONSOLE as shown in gure

The monitor connected to the HD-DB-15 VGA port of the CONSOLE must be capable of

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

type, please consult the monitor user’s manual. The StarView consumes negligible

power and is designed to run reliably without an external power adapter.

Computers Connection

Now you have two computers to connect to the StarView. Use a male-to-male

Mini-DIN-6 cable to connect from the rst PC’s keyboard port to the corresponding

KEYBOARD port; and, use another male-to-male Mini-DIN-6 cable from the PC’s mouse

port to the MOUSE port. Connect your computers VGA port to the HD-DB-15 port of

the StarView as shown in gure 2 using a VGA male-to-female cable. Follow the same

procedures for the second computer using the KEYBOARD and MOUSE port.

Instruction Manual

If your computer incorporates a serial mouse, a mouse adapter should be connected to

the computer’s mouse port as shown in gure 3.

(Note: use only the mouse adapter supplied with the SV231)

NOTE:

1. The StarTech.com SV231’s automatic mouse conversion system allows you to

connect computers using serial mice.

2. The mouse adapter can only be used on the PC side and 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” at the PC side.

Instruction Manual

Initial Power-up

Make sure all computers and the StarView SV231’s are powered down during

installation. After connection, power up the computers. The StarView can be powered

from the computers. This procedure ensures the StarView receive computer settings

correctly when computer boots.

NOTE: You may hot plug any addittional powered-down computer to the StarTech.com

SV231 at any time after the initial power up.

Operations

Front Panel Operation

You may switch to a dierent computer by pressing the front panel push-button

directly or by issuing hot-key commands. The front-panel red indicator changes to

reect the computer port selected. The indicator ashes while in either Auto Scan or

Manual Scan mode.

Hot-key Commands

Hot-key command is a short keyboard sequence to select a computer or to activate

computer scan. StarTech.com interprets keystrokes for hot-keys all the time. A hot-key

sequence starts with two left Ctrl keystrokes followed by one or two more keystrokes.

A built-in buzzer generates a high-pitch beep for correct hot-key command; otherwise,

one low-pitch beep for error is generated and the bad key sequence will not be

forwarded to the selected computer.

• To select a computer: left Ctrl + left Ctrl + 1 Selects the computer

at port 1. Left Ctrl + left Ctrl + 2 Selects the computer at port 2.

NOTE: Do not use the keypad at the right of the keyboard.

• To start Auto Scan, automatically scan powered-on computers one by one at a xed

interval: 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 left Ctrl + left Ctrl + F2 Press Up or Down 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: left Ctrl + left Ctrl + F3. The SV231 generates 1 to 4 beeps indicating

scan interval of 3, 8, 15, and 30 seconds respectively.

• To adjust keyboard typematic rate (characters/sec), this setting over-rides that of

BIOS and any operating systemL left Ctrl + left Ctrl + F4. The SV231 generates 1to 4

beeps corresponding to 10, 15, 20 and 30 characters/sec respectively.
