TABLE OF CONTENTS

The Master View CS-142 CPU 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 View, 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-142, you can easily access two computers in
a cost effective manner.
The Master View CS-142 provides two convenient methods to access the PCs
connected to the system: using the push button Selection switch located on the
unit’s top panel; 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-142 intercepts keyboard input directly, 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-142
installation. By allowing a single console to manage both of the attached PCs, the
Master View CS-142 eliminates the expense of purchasing a separate keyboard,
monitor, and mouse for each PC. Additionally, 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
User's Manual 3
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.
• Either a 6-pin mini-DIN (PS/2 style), or DB-9 (standard serial), mouse port.
• 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-142, for optimum signal integrity and to simplify the layout, we
strongly recommend that you use the high quality CS Custom Cables that are
provided as part of the package.
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.
• If your PC uses standard serial connectors for the mouse ports you can
use a Serial-to-PS/2 adapter, in order to plug the cable into the PC’s
mouse port.
• Be aware, however, that because of the wiring and pin assignments,
attempting to use standard serial extender cables with adapters at both
ends will not work. You cannot use a Serial-to-PS/2 adapter at the end
that plugs into the CS-142.

Unpacking

used on the PC side of the connection. Attempting to use the adapters at
the Master View side of the connection will not work.

Installation
User's Manual 6
Before you begin, make sure that power to all the devices (Master View CS-142 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-142 unit.
2. Use the extender cables (as described in the Hardware Requirements and
Unpacking sections), to connect the monitor, keyboard and mouse ports of the PCs
to the Master View CS-142 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.
3. If you are using a DC power adapter, plug it into the Master View’s Power Jack.
Note: The CS-142 does not require external power. Use of a DC power adapter
is optional, and requires a separate purchase.
4. Turn on the power to the connected PCs.

Operation
User's Manual 7
Controlling both PCs in your Master View CS-142 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-142’s Power On default is to link to Port 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 Port Selection
methods (described below), to switch to the active PC on Port 2.
Manual Port Selection
With Manual Port Selection you simply press the Port Selection button on the
Master View’s top panel to switch back and forth 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 Port Selection button. The
Master View CS-142 provides several Hot 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 or RightAlt+RightCtrl+RightShift).
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]

User's Manual 8
Auto Scan Mode:
The Master View CS-142’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. 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.
