Overview
The CS-74E KVM (Keyboard, Video, Mouse), Switch is a
control unit that allows acess to up to four computers from a
single console (keyboard, monitor, and mouse). With its custom
designed connectors, the CS-74E significantly reduces the
number of ports required for a 4 port KVM switch.
The special connector design, featuring a custom SPDB-15
male connector for the keyboard, video, and mouse, provides
several advantages over standard KVM switch
implementations: 1) increased reliability; 2) a handsome,
space-saving, vertical-standing, modern appearance; and
3) neater, more efficient, cabling that eliminates the usual
tangled cable mess.
Setup is fast and easy; plugging cables into their appropriate
ports is all that is entailed. There is no software to configure; no
need to get involved in complex installation routines; and no
need to be concerned with incompatibility problems. Since the
CS-74E intercepts keyboard and mouse input directly, it works
on any hardware platform and with all operating systems.
The CS-74E provides two convenient computer access
methods: 1) switching the KVM focus to a computer by
pressing one of the push button port selection switches located
on the unit’s front panel; and 2) switching to the target computer
by entering hotkey combinations from the keyboard.
There is no better way to save time and money than with an
CS-74E installation. By allowing a single console to manage all
of the computers, the CS-74E 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 another.

Components
Front View:
1. Port Selection Switches
MPress a switch to give the KVM focus to the system
attached to its corresponding port.
MPressing Buttons 1 and 2 simultaneously starts Auto
Scan Mode (see p. 9).
MWhile in Auto Scan Mode, pressing any button exits Auto
Scan Mode and switches the KVM focus to its
corresponding port.
2. Port LEDs
The Port LEDs are built into the Port Selection Switches. A lit
LED indicates that its corresponding Port is the one that has
the KVM focus.
Depending on the Port’s status, the LED may flash
according to a specific pattern (see the table on p. 11 for
details).

1. Power Jack
The power adapter cable plugs in here.
Note: The CS-74E does not require external power. Use of
a power adapter is optional, and requires a separate
purchase.
2. Console Port Connector*
The Console Adapter Cable plugs in here.
3. CPU Port Connectors*
The KVM cables that connect the unit to the mouse,
keyboard, and video ports on the computers you are
connecting up can plug into any available port.
*The shape of the 15-pin CPU and Console port connectors
has been specifically modified so that only cables designed to
work with this switch can plug in (see the Cables section on
p. 3 for details).

Installation
Refer to the diagrams on p. 7 as you do the following:
1. Plug the Console Adapter Cable into the Console Port
Connector on the rear panel of the CS-74E.
2. Plug your keyboard, monitor and mouse into their respective
connectors on the Console Adapter Cable. The connectors
are color coded and marked with an approprieate icon for
easy identification.
3. Use the custom KVM cables (described in the Cables
section on p. 3), to connect the CS-74E CPU Ports to the
monitor, keyboard and mouse ports of the computers you
are installing.
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.
Note: The power adapter should be DC9V with the inside
positive and the outside negative:
5. Turn on the power to the computers.
Note: The CS-74E’s default is to link to the first computer
you turn on.

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

Operation
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-74E provides three
Hotkey navigation features:
MSelecting the Active Port
MAuto Scan Mode
MSkip Mode
Invoking Hotkey Mode:
All Hotkey operations begin by invoking Hotkey Mode. Invoking
Hotkey Mode takes three steps: 1) Press and hold down the
Num Lock key; 2) Press and release the asterisk key or the
minus key; 3) Release the Num Lock key:
[Num Lock] + [*];
or:
[Num Lock] + [-];
Note: The asterisk or minus key must be released within one
half second, otherwise Hotkey invocation is canceled
and it has no effect.

When Hotkey Mode is active:
MThe Caps Lock and Scroll Lock LEDs flash in succession to
indicate so. They stop flashing and revert to normal status
when you exit Hotkey Mode.
MOrdinary keyboard and mouse functions are suspended -
only Hotkey compliant keystrokes and mouse clicks
(described in the sections that follow), can be input.
MPressing [Esc] or [Spacebar] exits Hotkey Mode.
Selecting the Active Port:
Each CPU port is assigned a numeric Port ID (1 - 4). You can
give the KVM focus directly to any computer on the installation
with a Hotkey combination as follows:
1. Invoke Hotkey Mode (see p. 8)
2. Press and release the computer’s Port ID number (1, 2, 3, or 4)
After you press the number, the KVM focus switches to the
designated computer and you automatically exit Hotkey Mode.
Auto Scan Mode:
The CS-74E’s Auto Scan feature automatically cycles through
the ports at regular 5 seconds intervals so that you can monitor
the computer activity without having to take the trouble of
switching manually. To invoke Auto Scan Mode:
1. Invoke Hotkey Mode (see p. 8)
2. Press and release [A]
Once scanning begins, it continues until you press [Esc] or
[Spacebar] to exit Auto Scan Mode. The Port that is active at
the time scanning stops remains active.
Note: 1. While Auto Scan Mode is in effect, ordinary keyboard
and mouse functions are suspended. You must exit
Auto Scan Mode by pressing [Esc] or [Spacebar] in
order to regain normal control of their use.
2. Pressing [Esc] or [Spacebar] exits both Auto Scan
Mode and Hotkey Mode.

Skip Mode:
This feature allows you to skip from the currently active Port to
the Previous or Next one with a single keystroke. In contrast to
Auto Scan Mode (which switches Ports at a fixed interval), you
can dwell on a particular port for as long or as little as you like.
To activate Skip Mode:
1. Invoke Hotkey Mode (see p. 8)
2. Press [ ← ] to skip from the current port to the port that
comes before it (3 to 2; 2 to 1, etc.).
3. Press [ →] to skip from the current port to the port that comes
after it (1 to 2; 2 to 3, etc.).
Note: 1. Skip Mode remains in effect until you exit it. You can
use [ ← ] and [ →] as often as you like. Ordinary
keyboard and mouse functions are suspended - only
[← ] and [ →] can be input. You must exit Skip Mode
in order to regain normal control of the console.
2. Pressing [Esc] or [Spacebar] exits both Skip Mode
and Hotkey Mode.

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), this unit only
supports all of the extra features of the
Microsoft Intellimouse. It supports the
scroll wheel function of most other mice.

Troubleshooting Notes:
1. This unit is designed to work with PS/2 keyboards and mice.
XT (84 key) and AT keyboards will not work. Serial mice will
not work.
2. Some 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.
