Introduction
Overview
The CS724KM is a 4-port USB KM Switch that enables users to control up to
4 computers with a single keyboard and mouse. Two switches can be daisychained to enable control of up to 8 computers from a single console.
The CS724KM features various innovative port selection methods. Users can
switch between the connected computers via front panel pushbutton, keyboard
hotkey, mouse cursor, mouse wheel, and RS-232 commands. The mouse
cursor method adopts ATEN’s exclusive Boundless Switching technology,
which provides an intuitive way to switch control to another computer by
simply moving your mouse cursor across a screen border and onto the target
co m puter d isplay. Move the mouse cu r sor in any direc tion to s w itch the control
focus without limitations.
The CS724KM’s Boundless Switching function supports extended desktops
with up to sixteen monitors total, expediting the process of switching between
computers for a smooth and hassle-free user experience. In addition to making
multitasking across multiple displays more efficient, this function is especially
useful in emergencies that necessitate the immediate monitoring and
management of computers.
The CS724KM also provides an intuitive GUI-based configuration utility that
allows users to customize their mouse cursor movement paths according to the
specific monitor layout at the desktop or workstation. The configuration tool is
easy to set up and compatible with Windows operating systems.
Further advanced features of the CS724KM include bus-power mode which
means no external power adapter is required, as well as independent switching
of the keyboard/mouse, USB peripheral, and audio focus via hotkeys. With a
rich feature set, the CS724KM is designed to simplify administrative tasks,
save space, and increase work productivity in multi-monitor extended desktop
environments, and is especially suitable for complex multitasking applications
in control rooms in any industry.

Daisy Chain Installation
To control even more computers, one additional CS724KM unit can be daisy
chained from the First Stage unit.
To set up a daisy chain installation, refer to the installation di agr am on page 13
(the numbers in the diagram correspond to the steps below), and do the
following:
1. Cable up the computers according to the information provided under
Single Stage Installation, page 9.
2. Repeat the step above for the Second Stage unit. When setting up the
second stage unit, connecting a keyboard and mouse to the console ports is
optional (see Note 2, below).
3. Use an RJ-45 cable to connect the Serial port on the Primary unit to the
Serial port on the Secondary unit.
4. On the Primary unit, set the Station Switch to P.
1. On the Secondary unit, set the Station Switch to S.
Note: 1. In a daisy-chained installation, set one Station Switch to P and the
other to S. If the Station Switch on both CS724KM units are set
to the same position (P or S), the console on both CS724KM units
will not work.
2. If two CS724KM units are connected with a console (keyboard/
mouse), the console on the Primary unit can control all computers
connected to the Primary and the Secondary units; however, the
console on the Secondary unit will not be able to control any
computers on the installation.
3. The maximum RJ-45 cable length is 150 meters.
6. After both units are up, power on the computers.
Note: Make sure the computers and devices that the CS724KM connects
to are also properly grounded.

Basic Operation
Port Selection
There are five methods to switch between the computers: Manual – by pressing
the port selection pushbuttons on the front panel; Mouse – by double-clicking
the scroll wheel; Hotkey – by entering key combinations on the keyboard;
Boundless Switching– by moving the mouse cursor across display borders; and
RS-232 – by entering serial commands.
Manual Switching
For manual port selection:
Press and release a port selection pushbutton to bring the KM, USB hub
and audio focus to the computer attached to its corresponding port.
Note: Pushbuttons will be disabled when the Driver AP is running.
Mouse Switching
For mouse port selection: Double-click the scroll wheel of your USB mouse to
cycle through the ports.
Note: 1. Mouse switching is only supported by USB 3-key scroll wheel mice.
2. Mouse switching is disabled by default. See Mouse Port Switching,
page 26, to enable mouse switching.
3. Mouse Emulation must be enabled. See Mouse Emulation, page 26.
4. Mouse switching will be disabled when the Driver AP is running.
Hotkey Switching
For Hotkey port selection: All port switches from the keyboard begin by
pressing the Scroll Lock key twice (see Port Switching, page 19).
Note: Hotkey switching will be disabled when the Driver AP is running.

CS724KM User Manual
Boundless Switching
Boundless Switching is for port selection by moving the cursor across the
display borders – when the cursor appears on the next screen, the KM focus
switches. Before using Boundless Switching, you must turn off mouse
acceleration in the operating system and configure:
The screen size of all connected displays via hotkey (page 27), or the
Boundless Switching Configuration Utility (page 39); and
The monitor layout via hotkey (page 28), or the Boundless Switching
Configuration Utility (page 39).
Note: Hotkey [P] and [L] will be removed for extended desktops
boundless switching with firmware v1.1.102 or higher.
RS-232 Commands Switching
For RS-232 Serial Command port switching, see RS-232 Commands, page 63.
Note: RS-232 command port switching will be disabled when the Driver AP
is running.
Port ID Numbering
Each KM port section on the switch is assigned a port number 1 to 4. The port
numbers are marked (CPU 1, CPU 2, CPU 3, and CPU 4) on the rear panel of
the switch. The Port ID of a computer is derived from the KM port number it
is connected to. For example, a computer connected to KM port 2 has a Port I D
of 2. The Port ID is used to specify which computer gets the KM, USB hub,
and audio focus with the Hotkey port selection method (See Going Directly to
a Port, page 21 for details).
Under daisy chain installation, the KM port section on the switch is assigned a
port number 1 to 4 on a Primary CS724KM, and a Secondary CS724KM with
port number (1=5, 2=6, 3=7, and 4=8).

Hotkey Operation
The switch provides an extensive, easy-to-use, hotkey function that makes it
convenient to control and configure your KM installation from the keyboard.
Hotkeys also provide asynchronous independent switching of the keyboard/
mouse, USB hub, and audio focus. Therefore, you can give one computer the
keyboard/mouse focus, another the USB hub focus, while a third has the audio
focus.
Port Switching
All port switches begin with tapping the [Scroll Lock] key twice. The tables
below describe the actions that each key combination performs.
Note: 1. If using the [Scroll Lock] key conflicts with other programs running
on the computer, the [Ctrl] key can be used, instead. See Alternate
Port Switching Keys, page 23, for details.
2. Port Switching will be disabled for extended desktops boundless
switching when the Driver AP is running.
