USER'S MANUAL

Overview

The Master View CS-142 KVM (Keyboard, Video, Mouse), Switch is a control unit that allows access to two computers 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.

Setup is fast and easy; plugging cables into their appropriate ports is all that is entailed. There is no software to configure, so there is no need to get involved in complex software installation routines or be concerned with incompatibility problems. Since the Master View CS-142 intercepts keyboard input directly, it works on any hardware platform and with all operating systems.

The Master View CS-142 provides two convenient methods to access the computers 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.

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.

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 KVM 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 to use the PS/2-to-AT
keyboard adapter (Part No. 2A-106) provided with
this unit in order to plug the cable into the PC's
keyboard port.

Installation

Before you begin, make sure that power to all the devices 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 section), 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. 4.

3.

Turn on the power to the connected PCs.
• If your PC uses standard serial connectors for the
mouse ports you will need to use a PS/2-to-Serial
adapter (Part No. 2A-105, provided with this
package), in order to plug the cable into the PC's
mouse port.
• Only one keyboard and one mouse adapter are
provided with this package. If both of your computers
require the use of keyboard and mouse adapters, you
will have to purchase the additional adapters

separately. Any standard keyboard adapter will work,
but the mouse adapter requires the use of our Part No.

2A-105.

• Because of the wiring and pin assignments, you
cannot use a Serial-to-PS/2 adapter at the end that
plugs into the CS-142. Therefore, attempting to use a
standard serial extender cable with adapters at both
ends will fail.

Operation

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
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
Selecting the Active Port:

You can toggle between the two PCs by pressing and releasing the left or right Ctrl key twice [Ctrl]+[Ctrl].

Note: The combination must be on the same side (Left [Ctrl]+[Ctrl], or Right [Ctrl]+[Ctrl].

Auto Scan Mode:

The Master View CS-142's Auto Scan feature automatically switches between the two PCs at regular 5 seconds intervals so that you can monitor their activity without having to take the trouble of switching yourself. To invoke Auto Scan Mode, press and release the left Shift key, then press and release the right Shift key (Left [Shift]+Right [Shift]).

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.

*The Master View CS-142 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-142 when their mouse and keyboard ports are used simultaneously. To avoid this problem, only connect the mouse port or the keyboard port 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.
