Overview

The Master View CS-114A 4 Port KVM (Keyboard, Video, Mouse), Switch
is a control unit that allows access to four computer systems from a single
PS/2 keyboard, PS/2 mouse, and monitor console in a cost effective
manner.

There are three convenient methods to access the computers: Pushbutton
Selection Switches; Hotkey combinations; and a Foot Switch (optional).
Setup is easy; just plug cables into their appropriate ports. There is no
software to configure, nor any installation routines, or incompatibility
problems. Since the CS-114A 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-114A installation. Since a single console manages all of the attac hed
computers, the Master View CS-114A eliminates the expense of
purchasing a separate keyboard, monitor, and mouse for each system.
Additionally, it saves all the extra space they would take up, and el iminates
the inconvenience and wasted effort involved in constantl y having to move
from one computer to the other.

Cables

Although it is possible to use standard cables to connect the PCs to the
CS-114A, for optimum signal integrity and to simplify the layout, we
strongly recommend that you use the following high quality CS Custom
Cable sets:

PC Connector Type CS Custom Cable
AT (5 pin DIN) Keyboard and Serial Mouse 2L-1001 P/C (1.8m); or
PS/2 (6 pin mini-DIN) Keyboard and Mouse 2L-1001 3P/C (3m)
Dasiy Chain Master View CS114A Units

Note: 1. These cables have PS/2 style keyboard connectors. If your

computer only has an AT style keyboard socket, you will
need a keyboard adapter (Part No. 2A-106), in order to plug
into the computer’s keyboard port.

2. These cables have PS/2 style mouse connectors. If your
computer uses a 9 pin serial port, you will need a special
PS/2-to-Serial mouse adapter (Part No. 2A-105); a standard
mouse adapter will probably not work.

1. Power Jack

The CS-114A is designed to be non-powered (external power is not
required - its operation power comes from the computers). In
general, the only time that external power is required is when you
daisy chain it, or if operation becomes erratic because the unit isn’t
obtaining enough power from the computer connections. If you
choose to use external power, the power adapter cable plugs in
here.

2. DIP Switch

Installation

Before You Begin

To prevent damage to your installation due to ground
potential difference, make sure that all devices on the
installation are properly grounded.

Single Stage Installation

The most basic installation is a Single Stage installation, in which no
additional Master View’s are daisy chained down from the first unit. The
Master View CS-114A design also allows additional units to be daisy
chained down to two or three levels. To set up a single stage installation
do the following:

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. Otherwise,
the switch will receive power from the computer.

2. Plug the monitor, keyboard, and mouse into the Console port
connectors (located to the left of the CPU ports) of the Master View
CS-114A unit. Each port is labeled with an appropriate icon to
indicate itself.

3. Use extender cables (see the Hardware Requirements section), to
connect the keyboard, monitor, and mouse ports from any available
CPU Port (1 - 4), to the keyboard, monitor, and mouse ports of the
computers you are connecting up (see the diagram on p. 8).

4. If you choose to use an optional foot switch, plug its cable into the
Footswitch connector.

5. If you choose to use external power, plug the power adapter into an
AC source, then plug the cable into the CS-114A’s Power Jack.

Under non-powered operation, the unit gets its power from
the computers via the keyboard and mouse cables. If a
computer only supplies 3.3V of power for the keyboard and
mouse instead of 5V (as in the case of Notebooks, for
example), the unit will not receive enough power, and you
will need to use the external power adapter.

6. Turn on the power to the connected computers.

2001 - 01 -03

Two Stage Installation

To control even more computers, up to four additional Master View
CS-114A units can be cascaded from the CPU ports of the First Stage
unit. The cascaded Master Views that connect back to the First S tage unit
are considered Second Stage units. As many as 16 computers can be
controlled in a complete two stage installation.

Note: Mixing different Master View models on the same daisy chain

can cause problems with Hotkey port switching. We strongly
recommend that you use CS-114As for all the cascaded units.

To set up a two stage installation, do the following:

1. Make sure that power to all the devices you will be connecting up,
including all preexisting devices on the installation, 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. To prevent damage to your
installation due to ground potential difference, make sure that all
devices on the installation are properly grounded.

2. For the First Stage unit, plug the power adapter that came with it
into an AC power source, then plug the adapter cable into the its
Power Jack.

3. Use connector cable sets (see the Hardware Requirements section),
to connect the ports from any available CPU Port (1 - 4) on the First
Stage unit to the Console Port connectors of the Second Stage
CS-114A.

4. If you choose to use an optional foot switch, plug its cable into the
Footswitch connector.

5. Plug the power adapter that came with the unit into an AC power
source, then plug the adapter cable into the CS-114A’s Power Jack.

6. Repeat steps 3 - 5 for any other Second Stage Master View
CS-114A units you wish to connect.

7. Use connector cable sets to connect the keyboard, monitor, and
mouse ports from any available CPU Port to the keyboard, monitor,
and mouse ports of the computers you are connecting up (see the
diagram on p. 8).

8. Turn on the power to all the connected computers.

Three Stage Installation

The procedures for setting up a three stage installation are essenti ally the
same as for a two stage installation. With a three stage setup, however,
as many as 64 computers can be controlled in a complete installation.

Note: Master View units cannot be cascaded beyond the third level.

Operation

Powering Off and Restarting

If it becomes necessary to Power Off one of the Master View units, before
starting it back up you must do the following:

1. Shut down all the computers that are attached to it. If the unit is
operating under external power, unplug the power adapter cable. Do
the same for all the stations and all the computers that are daisy
chained down from it (all the child stations and the computers
attached to them).

Note: 1. If any of the computers have the Keyboard ’Power On’

2. Wait 10 seconds.
a) For CS-114As operating under external power, plug the power

b) After the externally powered units are up, turn the computers

Port Selection

Manual Port Selection

Manual port selection is accomplished either with the Port Selection
switches on the front panel of the Master View CS-114A unit, or with an
optional foot switch.

Port Selection Switches:

M

Press the Port Selection switch of the unit that corresponds to the
computer that you want to access. On a daisy chained installation,
you must press the Port Selection switch on the Master View Station
that connects directly to the computer you want to access.

Foot Switch:

M

Each time you step on the foot switch the active focus switches from
the current computer to the next one down on the installation. After
the last computer you cycle back to the first and start over.

function, you must unplug their power cords, otherwise the
switch will still receive power from the PC which will cause
problems when you bring the installation back up.

Hotkey Port Selection

Hotkey Port Selection allows you to select the active computer directly
from the keyboard. The Master View CS-114A provides the following
Hotkey Port Selection features:

M Selecting the Active Port
M Auto Scan Mode
M Last/Next Mode

Hotkey Port Selection is activated with one of two combinations:

M The default combination is [Alt+Ctrl+Shift]. If you use this

method, the c o m b in a t i o n mu s t al l be o n th e s am e si d e
(i.e., LeftAlt+LeftCtrl+LeftShift or RightAlt+RightCtrl+RightShift).

M The alternate combination is pressing and releasing both Ctrl

keys simultaneously ([Left Ctrl+Right Ctrl]). If this conflicts with
programs running on the computers, the default combination
must be used.

The activation combination is chosen with DIP Switch 3 on the rear panel
of the First Stage unit. Set the switch to ON for Alt+Ctrl+Shift (Hot Key 1);
set it to OFF for LCtrl+RCtrl (Hot Key 2).

Selecting the Active Port:

M

Since each CPU port is assigned a unique Port ID, you can direc tly access
any computer on any level of the installation using a Hotkey combination
that specifies the Port ID of the CPU Port that the computer is connected
to. The steps involved are:

1. Press and simultaneously release the Hotkey activation combination
(Alt+Ctrl+Shift or LCtrl+RCtrl)

2. Key in the appropriate Port ID one digit at a time (see note below).

3. Press [Enter] to complete your selection.

Note: The Port ID is a one, two, or three digit number that is

determined by the Stage Level and CPU Port number of the
Master View unit that the computer is connected to. The first
digit represents the CPU Port number of the First Stage unit; the
second digit represents the CPU Port number of the Second
Stage; the third digit represents the CPU Port number of the
Third Stage.

For example, to access a computer attached to a First Stage unit, simply
key in a one digit number (1 - 4), that corresponds to the CPU Port number
that the computer is connected to.

- 9 -

2001 - 01 -03

To access a computer attached to a Second Stage unit, key in a two digit
number for the Port ID (press and release each number separately). The
first digit represents the CPU Port number (1 - 4), on the First Stage unit
that the Second Stage unit is cascaded down from; the second digit
represents the CPU Port number on the Second Stage unit that the
computer is connected to.

Likewise, to access a computer attached to a Third Stage unit, key in a
three digit number following the method described for the Second Stage
unit. Some examples are given in the table below:

This Combination Does the Following

[Alt + Ctrl+ Shift] 1 [Enter] 0r
[LCtrl + RCtrl] 1 [Enter]

[Alt + Ctrl+ Shift] 1 2 [Enter] 0r
[LCtrl + RCtrl] 1 2 [Enter]

[Alt + Ctrl+ Shift] 4 2 3 [Enter] 0r
[LCtrl + RCtrl] 4 2 3 [Enter]

Auto Scan Mode:

M

Selects the computer connected to Port 1 on
the First Stage unit.

Selects the computer connected to Port 2 on
a Second Stage unit, connected back to Port
1 on the First Stage unit.

Selects the computer connected to Port 3 on
a Third Stage unit, connected back to Port 2
on a Second Stage unit, connected back to
Port 4 on the First Stage unit.

Auto Scan automatically switches among all the active CPU Ports of all
the Master View units in the installation at regular intervals, so that you
can monitor their activity automatically. The amount of time it dwells on
each port is determined with segments 1 and 2 of the First Stage unit’s
DIP Switch (see the Scan Time table in the Appendix for setting details.
To invoke Auto Scan Mode, key in the following Hotkey combination:

1. Press and simultaneously release the Hotkey activation combination
([Alt+Ctrl+Shift] or [LCtrl+RCtrl])

2. Press 0 (zero)

3. Press [Enter]

To exit Auto Scan Mode, press the [Spacebar]. The port that is currently
active at the time scanning stops remains active.

Note: While Auto Scan Mode is in effect, the console will not function.

You must exit Auto Scan Mode in order to regain control of the
console.

2001 - 01 -03

Last/Next Mode:

M

Last/Next mode enables you to easily switch from the currently active
computer to the previous or next available computer in the installation.
There are two methods of invoking Last/Next Mode: Basic Mode, and
Quick Mode.The choice of mode is made with DIP Switch 4. Set the switch
to Off for Basic Mode; Set the switch to On for Quick Mode.

Quick Mode:

With Quick Mode, Last/Next selection is always availabl e - it does not have
to be invoked as the [Alt+Ctrl+Shift] method does. At any time, simply
press LCtrl] + [LCtrl] to switch from the currently active computer to the
one previous to it; or press [RCtrl] + [RCtrl] to switch from the currently
active computer to the next one in the installation.

Besides being more convenient than Basic Mode, the advantage of this
method is that the keyboard remains active so you can use the console
to carry out commands on the accessed computer. The disadvantage is
that pressing the Ctrl keys may conflict with programs already running on
the computers.

Basic Mode:

1. Press and simultaneously release [Alt+Ctrl+Shift] or [LCtrl+RCtrl]

2. Press 9

3. Press [Enter]

4. Press the left Shift key (LShift) to switch from the currently active
computer to the one previous to it; press RShift to switch from the
currently active computer to the next one in the installation.

Note: With this method, while Last/Next Mode is in effect, the console

will not function. You must exit Last/Next Mode by pressing the
[Spacebar] in order to regain control of the console.
