Overview
The Master View CS-82A 4 Port 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 Master View CS-82A, you can easily access two
computers in a cost effective manner.
Setup is fast and easy; plugging cables into their appropriate
ports is all that is entailed. There is no software to configure;
there are no installation routines, and no incompatibility
problems. Since the Master View CS-82A intercepts keyboard
input directly, it works on any hardware platform and with all
operating systems.
The Master View CS-82A provides two convenient methods to
access the computers connected to the system: 1) push button
Port Selection Switches located on the unit’s front panel; and 2)
Hotkey combinations entered from the keyboard.
There is no better way to save time and money than with a
Master View CS-82A installation. Since a single console
manages all of the computers, the CS-82A setup: 1) eliminates
the expense of having to purchase a separate keyboard,
monitor, and mouse for each computer; 2) saves all 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.

Installation
Refer to the diagram on the next page as you perform the
following steps:
1. Plug the monitor, keyboard, and mouse into the Console
port connectors of the Master View CS-82A unit. Each port
is labeled with an appropriate icon to indicate itself.
2. Use KVM cables (see the Hardware Requirements section),
to connect the keyboard, monitor, and mouse ports from any
available CPU Port (1 - 2), to the keyboard, monitor, and
mouse ports of the computers you are connecting up (see
the diagram on p. 7).
Note: If your computers use AT style connectors for the
keyboard, and/or standard serial connectors for the
mouse, refer back to the note in the Cables section
on p. 3.
3. If you choose to use external power (optional) plug the
power adapter into an external AC source; plug the power
adapter cable into the unit s power jack as shown in the
diagram on p. 7.
4. Turn on the power to the connected computers.

1. Before you begin, 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. Otherwise, the switch will receive power
from the computer.
2. To prevent damage to your installation due to ground
potential difference, make sure that all devices on
the installation are properly grounded. Consult your
dealer for technical details, if necessary.

Use of Mouse Port
Adapters This unit is designed to only work with PS/2 mice and computers with PS/2 type mouse
ports. PS/2 mouse signals and serial mouse
signals are different - adapters will not convert
the signals - therefore, the computer must be
equipped with a PS/2 type mouse port. Serial
mouse ports with adapters cannot be used.
Mouse needs to be reset. Unplug the mouse from the Console
Keyboard Port, then plug it back in.

Mouse set to Serial Mode. Some mice can be set to act as either a PS/2
or serial mouse. Make sure the mouse is set
to PS/2 mode.
Incorrect Mouse Driver. Check your Device Manager to be sure that
the correct driver for your mouse (obtained
from the manufacturer, or supplied by the
operating system), has been installed.
Because of the wide variety of mouse driver
standards for the modern series of mice (the
ones with the extra buttons and wheels), the
CS-82A only supports all the extra features of
the Microsoft Intellimouse. It supports the
scrollwheel function of most other mice,
however.
Video Problems Resolution and/or
Bandwidth set too high. This unit supports VGA, SVGA, Multisync, and XGA (interlaced), with resolutions of up to
1920x1440. The maximum bandwidth is 180
MHz.
Cable quality not good
enough. We strongly recommend that you use the high quality cables provided with this package.
Using high quality cables should eliminate
possible video problems.
1The unit 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.
2Some Notebooks, notably the IBM Thinkpad and Toshiba Tecra,
have trouble when their mouse and keyboard ports are used
simultaneously. To avoid this, 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.
