Overview
The Master View CS-12 / CS-12C KVM (Keyboard, Video,
Mouse), Switch is a control unit that allows access to two
computers from a single console (keyboard, monitor, and
mouse). 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 CS-12 / CS-12C, you can easily access two
computers in a cost effective manner.
The Master View CS-12 / CS-12C provides two convenient
methods to access the computers connected to the system:
using the push button Port Selection Switch located on the
unit’s side panel; and entering hotkey 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
CS-12 / CS-12C intercepts keyboard input directly, it works on
all hardware platforms and operating systems*.
There is no better way to save time and money than with a
Master View CS-12 / CS-12C installation. Since a single
console manages both of the computers, a CS-12 / CS-12C
setup: 1) eliminates the expense of having to purchase a
separate keyboard, monitor, and mouse for each computer; 2)
saves the space those extra components would take up; 3)
saves on energy costs; and 4) eliminates the inconvenience
and wasted effort involved in constantly moving around from
one computer to another.
* Mac and Sun systems may require additional equipment. See
p. 5 for details.

Cables
Although it is possible to use standard KVM cables to connect
the computers to the switch, for optimum signal integrity and to
simplify the layout, we strongly recommend that you use high
quality CS Custom KVM cables, like the ones provided as part
of the CS-12C package.
CS Custom KVM cable sets are available in 1.2, 1.8, 3, and 6
meter lengths (see table, below):

11 for details).
5. Po rt Sel ecti on Sw itch
Pressing this push button switch toggles the KVM focus

* Since the KVM cables come with PS/2 style connectors, certain
hardware configurations (such as notebooks), that don’t have
two PS/2 ports may require the use of an adapter, as shown
below:
Adapter Purpose
UC-100KM
A Two PS/2 ports to USB adapter for PCs,
Macs and Sun systems
If you require an adapter, contact your dealer.

Installation
1. Make sure that power to all the devices you will be
connecting up have been turned off. You must
unplug the power cords of any computers that
have the Keyboard Power On function.
2. To prevent damage to your equipment, make sure
that all devices you will be connecting up are
properly grounded.
1. Plug the monitor, keyboard, and mouse into the Console
port connectors (located on the left side panel) of the switch.
2. Use KVM cables (as described in the Cables section, p. 4),
to connect the switch’s CPU A and CPU B ports (located on
the front and rear panel, respectively), to the keyboard,
monitor, and mouse ports of the computers you are installing.
Note: The Power On default is to link to the first computer
you turn on.

Operation
Controlling both computers from a single console could not be
easier. Two port selection methods that provide instant access
to the computers are available:
Manual Port Selection
M
Hotkey Port Selection
M
Manual Port Selection
With Manual Port Selection, you simply press the Port
Selection button on the Master View’s side panel to toggle the
KVM access between the computers. The Selected LED on the
top panel lights to indicate which port has the focus.
Hotkey Port Selection
Hotkey port selection allows you to directly access a computer
from the keyboard, instead of having to manually switch to it
with the Port Selection button. The CS-12 / CS-12C provides
two hotkey port selection features:

Selecting the Active Port - Default Method:
M
The default method to toggle the KVM focus between the two
ports from the keyboard is to tap the left or right Ctrl key twice:
[Ctrl] [Ctrl]
Note: The combination must be on the same side (both Left, or
both Right).
Selecting the Active Port - Alternate Meth od:
M
If the Ctrl key combination conflicts with programs running on
your computer, you can switch the hotkey to the Scroll Lock key
by pressing and holding the Port Selection button for three (3)
seconds. After this, tap the Scroll Lock key twice to toggle the
KVM focus.
[Scroll Lock] [Scroll Lock]
Note: To switch back to the default hotkey, press and hold the
Port Selection button for three (3) seconds again.

Auto Scan Mode:
M
The Auto Scan feature automatically switches between the two
computers at regular intervals so that you can monitor their
activity without having to take the trouble of switching yourself.
Invoking Auto Scan
To invoke Auto Scan Mode, press and simultaneously release
the left Shift key, then press and release the right Shift key:
[Left Shift] [Right Shift].
Setting the Scan Interval
The default amount of time that Auto Scan dwells on each port
is five seconds. You can change the scan interval at any time
while Auto Scan Mode is in effect by keying in a number from 1
to 4. The scan interval that corresponds to the number is shown
in the table below:
Number Scan Interval

Once scanning begins, it continues until you press the
[Spacebar] to exit Auto Scan Mode. The port that has the KVM
focus at the time scanning stopped remains active.
Note: While Auto Scan Mode is in effect, the console will not
function normally. You must exit Auto Scan Mode (by
pressing the [Spacebar]) in order to regain normal
control of the console.

Troubleshooting Notes:
1. The unit is designed to work wit h PS/ 2 keyboards and mice.
XT (84 key) and AT keyboards will not work. Serial mice will
not work.
2. Some Not ebooks, notably the IBM Thinkpad and Toshiba
Tecra, have trouble when their mouse and keyboard ports
are used simultaneously. To avoid this, either use a PS/2 to
USB adapter (as described on p. 5), or only connect the
mouse port or the keyboard port. If you connect the mouse
port, you will need to use the notebook’s keyboard when the
notebook becomes the active computer.
