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
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 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.

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.

SV231 at any time after the initial power up.
Operations
Front Panel Operation
You may switch to a dierent computer by pressing the front panel push-button
directly or by issuing hot-key commands. The front-panel red indicator changes to
reect 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
