Overview
The CS-74A KVM (Keyboard, Video, Mouse), Switch is a
control unit that allows the control of up to four computers from
a single console (keyboard, monitor, and mouse). With its
custom designed connectors, the CS-74A reduces the number
of ports required for a 4 Port KVM switch from 15 (10 PS/2 and
5 HDB-15) to only 5 (4 custom designed SPDB-15 connectors
for the computer attachments, and a single, custom designed,
integrated, SPDB-15 connector for the keyboard, video, and
mouse).
The special connector design provides several advantages
over standard KVM switch implementations: 1) increased
reliability; 2) a handsome, space-saving, vertical-standing,
modern appearance; 3) neater, more efficient, cabling -
eliminating the usual tangled mess.
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 installation routines
or be concerned with incompatibility problems. Since the
CS-74A intercepts keyboard and mouse input directly, it works
on any hardware platform and with all operating systems.
The CS-74A provides two convenient methods to switch the
KVM focus among the computers: 1) by pressing push button
port selection switches located on the unit’s front panel; and 2)
by entering Hotkey combinations from the keyboard.
There is no better way to save time and money than with an
CS-74A installation. By allowing a single console to manage all
of the attached computers, the CS-74A eliminates the expense
of purchasing a separate keyboard, monitor, and mouse for
each one. Additionally, it saves the extra space and energy
costs that they would require, and eliminates the inconvenience
and wasted effort involved in constantly having to move from
one computer to the other.

Style) keyboard port with +5V DC on pin 5 and ground on
pin 4.
Cables
Only CS Custom cable sets specifically designed to work with
this switch may be used. One Console Connector Cable and
four KVM cable sets (2 x 1.2 m; 2 x 1.8 m) are provided with
this package.
Note: 1. Cable sets are also available in 3 m lengths. If you need
additional cables, or 3 m cables, contact your dealer.
2. If your computer uses a standard AT style keyboard
socket, you will need a PS/2-to-AT keyboard adapter
(Part No. 2A-106 or any standard keyboard adapter),
in order to plug the cable into the Computer’s
keyboard port.
3. The CS-74A only supports PS/2 style mice - it does
not support serial mice.

Installation
The CS-74A can either lay flat on the desktop or stand upright.
To have it stand upright, unsnap its mounting stand from the
bottom of the unit; turn it 90o; and snap it back into place. See
the photo on the front page for an example.
Refer to the diagram on p. 7 as you do the following:
1. Plug the Console Connector Cable into the Console Port
Connector on the rear panel of the CS-74A.
2. Plug your keyboard, monitor and mouse into the Console
Keyboard, Monitor and Mouse connectors of the Console
Adapter Cable.
3. Use the CS Custom KVM cables to connect the CS-74A
CPU Ports to the monitor, keyboard and mouse ports of the
computers you are installing.
Note: If your computers use AT style connectors for the
keyboard, refer back to the note in the Cables section
on p. 3.
4. If you choose to use external power, plug the power adapter
into an AC power source, then plug the power adapter cable
into the unit’s Power Jack. See the note on the next page for
information about the adapter.
5. Turn on the power to the computers.
Note: The CS-74A’s default is to link to the first computer
you turn on.

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
2003-02-18

Note: 1. In order to fit into the jack, the power adapter cable
should have an Lshaped plug.
2. The power adapter should be DC9V with the inside
positive and the outside negative:

Operation
Controlling all the computers in your CS-74A installation from a
single console could not be easier. Two port selection methods
that provide instant access to the computers are available:
MManual Port Selection
MHotkey Port Selection
Manual Port Selection
With Manual Port Selection you simply press the appropriate
Port Selection switch on the unit’s front panel to give the KVM
focus to its corresponding port. The Port LED lights to indicate
that its port has the KVM 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-74A provides three
Hotkey navigation features:
MSelecting the Active Port
MAuto Scan Mode
MSkip Mode
