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 identifies the mouse and switches to proper mouse
protocol.

Installation
Device Connection
Turn your computers off. 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 figure
1.
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 first 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 figure 2 using a VGA male-to-female cable. Follow the same
procedures for the second computer using the KEYBOARD and MOUSE port.

If your computer incorporates a serial mouse, a mouse adapter should be connected to
the computer’s mouse port as shown in figure 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.

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

Operations
Front Panel Operation
You may switch to a different computer by pressing the front panel push-button
directly or by issuing hot-key commands. The front-panel red indicator changes to
reflect the computer port selected. The indicator flashes 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.

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