Introduction
Overview
The CS-72E / CS-74E KVM (Keyboard, Video, Mouse), switch is a control
unit that allows access to two (CS-72E) or four (CS-74E) computers from a
single console (keyboard, monitor, and mouse).
With its custom designed connectors, the CS-72E / CS-74E significantly
reduces the number of ports required for a 2 or 4 port KVM switch. The design
features a custom SPHD-15 male connector for the keyboard, video, and
mouse, and SPHD-15 female connectors for the cables that connect the switch
to the computers.
The SPHD connectors provide several advantages over standard KVM switch
implementations: 1) increased reliability; 2) a handsome, space-saving,
modern appearance; and 3) neater, more efficient, cabling that eliminates the
usual tangled cable mess. Combined with the modern looking, compact, dual
function case that allows the unit to either stand upright or lay flat, the switch
can easily be placed in almost any convenient, unobtrusive location.
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-72E / CS-74E intercepts keyboard and mouse input
directly, it works on any hardware platform and with most operating systems.
The CS-72E / CS-74E provides two convenient methods to bring the KVM
focus to the target computer: 1) by pressing one of the 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 access your multiple computer installation than with
a CS-72E / CS-74E KVM switch. By allowing a single console to manage all
of the computers, the CS-72E / 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 additional consoles would require, and it
eliminates the inconvenience and wasted effort involved in constantly having
to move around from one computer to another.

Installation
Refer to the installation diagrams on the next page (the numbers in the
diagrams correspond to the steps indicated below) as you do the following:
1. Plug the Console Adapter Cable into the Console Port Connector on the
rear panel of the switch.
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 appropriate icon for easy identification.
3. Use the custom KVM cable sets (described in the Cables section, page 3),
to connect the CS-74E KVM 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: Under ordinary circumstances the switch doesn't require external
power. If, for some reason, you find that the quality deteriorates
(when using long cables, for example), you may want to add a power
adapter. The power adapter should be DC9V; 300mA, with the
inside positive and the outside negative:
5. Power on the computers.
Note:The CS-74E’s default is to link to the first computer that is
powered on.
Make sure the computers and devices that the CS-74E connects to
are also properly grounded.
1. Important safety information regarding the placement of this
device is provided on page iv. Please review it before proceed-
ing.
2. To prevent damage to your installation from power surges or
static electricity. It is important that all connected devices are
properly grounded.
3. 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.

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’s Port LED lights to indicate that it has the KVM focus.
Pressing and holding buttons 1 and 2 for more than 3 seconds invokes
Auto Scan Mode. Auto Scan Mode allows you to automatically cycle
through the ports at regular 5 seconds intervals so that you can monitor the
computer activity without having to constantly switch ports yourself.
When a port is being accessed under Auto Scan Mode, its corresponding
Port LED flashes.
While Auto Scan Mode is in effect, ordinary keyboard and mouse
functions are suspended. You must exit Auto Scan Mode in order to regain
normal control of their use.
To exit Auto Scan Mode, press any port selection switch. The KVM focus
goes to the port that corresponds to the switch you pressed.
CS-72E / CS-74E User Manual

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
switches. For both the CS-72E and CS-74E, hotkey operations begin by
tapping the Scroll Lock key twice.
Port Selection
For the two port CS-72E, tapping [Scroll Lock] [Scroll Lock] toggles the
KVM focus between the two ports.
For the four port CS-74E, hotkey port switching is explained in the table
below:
Hotkey Action
[Scroll Lock] [Scroll Lock] [] Brings the KVM focus from the port that
currently has the focus to the next port on the
installation: 1 to 2; 2 to 3; 3 to 4; 4 to 1.
[Scroll Lock] [Scroll Lock] [] Brings the KVM focus from the port that
currently has the focus to the previous port on
the installation: 4 to 3; 3 to 2; 2 to 1; 1 to 4.
[Scroll Lock] [Scroll Lock] [Fn] Where Fn represents a function key (from [F1]
to [F4]) that corresponds to the CS-74E’s KVM
port (1 to 4). When you enter the combination
the KVM focus goes directly to the port that
corresponds to the function key.
For example, if you were to enter the following
combination:
[Scroll Lock] [Scroll Lock] [F4]
The KVM focus would go to the computer
connected to port 4.
3. Operation
13
Auto Scan Mode
In addition to manually invoking Auto Scan Mode (discussed on page 11), the
CS-74E also provides hotkey invocation.
To invoke Auto Scan Mode using hotkeys instead of manually, enter the
following combination:
[Scroll Lock] [Scroll Lock] [A][Enter]
While Auto Scan Mode is in effect, ordinary keyboard and mouse
functions are suspended. You must exit Auto Scan Mode in order to regain
normal control of their use.
To exit Auto Scan Mode, press [Esc] or [Spacebar]. The KVM focus
stays with the last port that was accessed under Auto Scan Mode.

Troubleshooting
1. This unit is designed to work with PS/2 keyboards and mice. XT (84 key) and AT key-
boards 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.
