Product Overview
Feature Overview
The SwitchView and SwitchView DT allow you to con-
trol multiple PCs, easily and affordably, with just one
keyboard, monitor and mouse. There is no software to
install or boards to configure, so installation is simple.
SwitchView works with IBM PC/AT and PS/2 systems
with support for VGA and SVGA video. PS/2 keyboard
and PS/2 mouse peripherals are supported through the
rear of the unit.
When you turn on your PCs, the SwitchView will boot
up each one without interruption by sending out the
proper signal to eliminate keyboard errors. PCs may be
powered-up one-at-a-time or all at once. The first avail-
able channel is automatically selected upon power-up.
You can switch computer channels two ways: via the
Select button on the SwitchView front panel, or through a
short keyboard sequence if the SwitchView is out of reach.
The SwitchView supports the following additional features:
• PS/2 mouse translation - your PS/2 mouse will
work with any attached PC, regardless of whether
the computer is serial or PS/2 mouse compatible!
• Extensive Mouse Support - The SwitchView
offers full support for the Logitech MouseMan
Wheel, Logitech Trackman Marble Wheel, Logitech
Trackman Marble FX, Microsoft Explorer mouse and
the Microsoft IntelliMouse family.
• Standard cables - use either Avocent-supplied or
standard straight-through cables to attach comput-
ers to the SwitchView unit.
• Built-in scanning feature - scan through all of
your attached PCs automatically. Scan every PC for
2 to 60 seconds each.

The SwitchView also accepts standard straight-through
cables for these connections.
Connecting your peripherals
1. Your VGA monitor, keyboard and mouse connect to
the SwitchView unit instead of your computer. Plug
your PS/2 keyboard cable into the purple port
on the back of your unit in the User Console section.
Plug your PS/2 mouse cable into the green port
and your VGA video cable into the blue port.

Basic Operations
PCs may be powered-up one-at-a-time or all at once.
The green LEDs over each channel will light, indicating
that the attached computer is powered on. After
power-up, a lit amber LED indicates the selected com-
puter. Other PCs may now be selected for operation.
Selecting a PC
There are two ways to select a PC. One way is via
the Select push-button. This selects the next computer
in sequence. Holding the push-button down will enable
scanning of all available channels until the button is
released. The second way is by entering a short sequence
of keystrokes on the keyboard. This is called keyboard, or
hot-key, switching.
Press the Control key twice within one second to place
your SwitchView in Command Mode. Your keyboard
LEDs will flash to verify that you are operating in Com-
mand Mode. Now, whatever you type will be interpreted as
SwitchView system commands until Enter is pressed to
accept the command or Escape is pressed to cancel.
In Command Mode, type the letter for the PC you wish
to select. Press Enter to accept the new address (Addr).
See below.
Key Sequence Action
1. <CTRL><CTRL>B<Enter> Selects Channel B.
2. <CTRL><CTRL>C<Enter> Selects Channel C.
EXAMPLE
Key Sequence Action
<CTRL><CTRL>Addr<Enter> Selects an active channel via keyboard.

Connecting your Computers
2. Power down all computers that will be part of your
SwitchView system.
3. Locate the appropriate cable kit to attach your first
computer to the SwitchView. Now, plug the key-
board cable from the kit into the purple con-
nector of any available port on your SwitchView.
Ports are labeled A-B on the 2-Port and A-D on
the 4-Port.
Next, plug your mouse cable into the green con-
nector of the same port.
Plug the video cable into the blue monitor connector.
Plug the remaining cable ends into the matching
ports on your computer. For serial computers,
use only Avocent provided adaptors. Tighten all
thumbscrews.
4. Repeat step 3 for each additional computer to be
attached and then power-up all attached computers.

Scanning PCs
The scanning feature allows you to automatically moni-
tor, or scan, each PC in your SwitchView system. If you
use the keyboard during scanning, the scan will pause
until you finish, then resume with the next PC. The
length of time each PC’s video remains on the screen, or
dwell time, can be changed at any time. Scanning will
be halted if the Halt command is entered or if another
PC is selected.
The following key sequences control scanning:
If you would like mouse and keyboard activity to sus-
pend scanning, see the commands below.

<CTRL><CTRL>Dnn<Enter> Congures the dwell time. Substitute nn
with a value from 2 to 60 seconds. The
default value is 5 seconds.
<CTRL><CTRL>SG<Enter> Enables the scan Go command.
<CTRL><CTRL>SH<Enter> Enables the scan Halt command.
Key Sequence Action
<CTRL><CTRL>M+<Enter> Mouse will suspend scanning.
<CTRL><CTRL>M-<Enter> Mouse will not suspend scanning. (default)
