Overview
The Master View CS-12 KVM Switch is a control unit that allows
access to two PC systems from a single console (keyboard, mouse,
and monitor). Before the development of the Master Vi e w, the only
way to control multiple computer configurations from a single
console was through a complex and costly network system. Now,
with the Master View CS-12, you can easily access two computers in
a cost effective manner.
The Master View CS-12 provides two convenient methods to access
the PCs connected to the system: using the push button Selection
switch located on the unit’s right side; and entering Hot Key
combinations from the keyboard. Setup is fast and easy; plugging
cables into their appropriate ports is all that is entailed. There is no
software to configure, no installation routines, and no incompatibility
problems. Since the Master View CS-12 intercepts keyboard input
d i r e c t l y, it works on any hardware platform and with all operating
systems.
There is no better way to save time and money than with a Master
View CS-12 installation. By allowing a single console to manage both
of the attached PCs, the Master View CS-12 eliminates the expense
of purchasing a separate keyboard, monitor, and mouse for each PC.
Ad d i t i o n a l l y, it saves all the extra space they would take up, and
eliminates the inconvenience and wasted effort involved in
constantly having to move from one PC to the other.

Hardware Requirements
Console
• One VGA, SVGA, or Multisync monitor capable of the highest
resolution that you will be using on any PC in the installation
• One PS/2 mouse
• One PS/2 style keyboard or AT style keyboard plus keyboard
adapter
PC
The following equipment must be installed on each PC that is to be
connected to the system:
• A VGA, SVGA or Multisync card.
• A 6-pin mini-DIN (PS/2 style).
• Either a 6-pin mini-DIN (PS/2 Style) keyboard port with +5V DC on
pin 4 and Ground on pin 3, or a 5-pin DIN (AT Style) keyboard port
with +5V DC on pin 5 and ground on pin 4.*
* See the note under Cables in the next section.
Cables
Although it is possible to use standard extender cables to connect the
PCs to the Master View CS-12, for optimum signal integrity and to
s i m p l i fy the layout, we strongly recommend that you use the high
quality CS Custom Cables Part Number 2L-1001P/C.
Note: The keyboard and mouse cables have PS/2 style connectors
at each end:
• If your PC uses a standard AT style keyboard socket, you
will need an AT-to-PS/2 keyboard adapter, in order to plug
the cable into the PC’s keyboard port.
• CS-12 does not support Serial Mouse

Installation
Before you begin, make sure that power to all the devices (Master
View CS-12 and both PCs) you will be connecting up have been
turned off.
1. Plug the monitor, keyboard, and mouse into the Console port
connectors of the Master View CS-12 unit.
2. Use the extender cables (as described in the H a rd w a re
R e q u i re m e n t s and Unpacking sections ), to connect the monitor,
keyboard and mouse ports of the PCs to the Master View CS-12
CPU Ports, as shown in the diagram below.
Note: If your PCs use AT style connectors for the keyboard and
mouse ports, refer back to the note in the Cables Section on
p.3.
4. Turn on the power to the connected PCs.

Operation
Controlling both PCs in your Master View CS-12 installation from a
single console could not be easier. Two port selection methods that
provide instant access to either PC are available:
• Manual Port Selection
• Hot Key Port Selection
Note: The CS-12’s Power On default is to link to Po rt 1. If the PC
attached to Port 1 is inactive, the monitor will be blank so it
may appear as if the unit is not functioning. This is not the
case. Simply use one of the Po rt Selection methods
(described below), to switch to the active PC on Port 2.
Manual Port Selection
With Manual Po rt Selection you simply press the Po rt Selection
button on the Master Vi e w’s right side to switch back and fort h
between computers. The Selected LED on the top panel lights to
indicate which port is active.
Hot Key Port Selection
Hot Key navigation allows you to select the active PC directly from
the keyboard, instead of having to manually select it by pressing the
P o rt Selection button. The Master View CS-12 provides several H o t
Key navigation features:
• Selecting the Active Port;
• Auto Scan Mode.
• Last/Next Mode
Note: All Hot Key operations begin by pressing and releasing the
Alt+Ctrl+Shift combination. The combination must all be on
the same side (i.e., LeftAlt+LeftCtrl+LeftShift o r
RightAlt+RightCtrl+RightShift).
8
Selecting the Active Port:
Each CPU port is assigned a numeric ID (CPU1 or CPU2). You access
the PC attached to a port by specifying the Port ID as part of the Hot
Key combination as follows:
1. Press and release Alt+Ctrl+Shift
2. Key in the appropriate Port ID (1 or 2)
3. Press [Enter]
Auto Scan Mode:
The Master View CS-12’s Auto Scan feature automatically switches
between the two PCs at regular intervals so that you can monitor
their activity without having to take the trouble of switching yourself.
To invoke Auto Scan Mode, key in the following Hot Key combination:
1. Press and release Alt+Ctrl+Shift
2. Press and release 0 (zero)
3. Press [Enter]
Once scanning begins, it continues until you press the [Spacebar] to
exit Auto Scan Mode. The port that was currently active at the time
scanning stopped remains active.
Note: While Auto Scan Mode is in effect, none of the other keyboard
keys will function. You must exit Auto Scan Mode by pressing
the [Spacebar] in order to use the console for anything else.
Last/Next Mode:
The Last/Next feature is provided to enable you to quickly switch back
and forth between computers in order to monitor them manually,
instead of using Auto Scan Mode. This method lets you dwell on a
particular port for as long or as little as you like - as opposed to Auto
Scan Mode, which switches after a fixed interval.
9
To invoke Last/Next Mode, key in the following Hot Key combination:
1. Press and release Alt+Ctrl+Shift
2. Press and release 9
3. Press [Enter]
Once Last/Next Mode is active pressing the left Shift key (LShift ) ,
switches to the previous computer (from the currently active one);
pressing RShift switches to the next computer in the installation.
Note: While Last/Next Mode is in effect, none of the other keyboard
keys will function. You must exit Last/Next Mode by pressing
the [Spacebar] in order to use the console for anything else.

Action
Unplug the keyboard from the Console Keyboard
Port, then plug it back in.
Turn off the PCs and unplug the keyboard cable
from the Master View CS-12. Wait 5 seconds; plug
the keyboard cable back in to the CS -12; then turn
the PCs back on.
Press the [Spacebar] to exit Auto Scan or Last/Next
Mode.
Unplug the mouse from the Console Mouse Port,
then plug it back in.
Turn off the PCs and the Master View CS-12. Wait
five seconds; turn the Master View unit on; then
turn the PCs on.
The Master View CS-12 does not support some
combo mice (with extra buttons and wheels) which
can be used as either a PS/2 or serial mouse when
they are in serial mode - switch the mouse to PS/2
mode if you wish to use the extra buttons/wheels.
If the problem persists, change the mouse and/or
mouse driver. Try a regular mouse and a generic
mouse driver (like the ones that comes with the
operating system).
* The Master View CS-12 is designed to work with AT and PS/2
keyboards. Older XT (84 key) and some older AT keyboards ( those
with the function keys on the side), will not work.
** Some Notebook computers, notably the IBM Thinkpad and
Toshiba Tecra, have trouble working with the Master View CS-12
when their mouse and keyboard por
ts are used simultaneously. To
avoid this problem, only connect the mouse port or the keyboard
por
t to the Master View unit. If you connect the mouse port, you
will need to use the notebook’s keyboard when you switch to
make the notebook the active computer.
