Introduction
Overview
The CS72D / CS74D 2/4-Port USB DVI KVM Switch allows you to control
two or four computers using one USB mouse, USB keyboard and Digital
Visual Interface (DVI) monitor console. It supports digital video devices, such
as flat panel displays, data projectors, plasma displays and digital TVs.
The CS72D / CS74D comes with ATEN’s Video DynaSync
which eliminates boot-up display problems and optimizes resolution; as well
as Power On Detection, which means if one computer is powered off, the
CS72D / CS74D automatically switches to the next powered-on computer.
The CS72D / CS74D is audio enabled. You can listen to the audio output of
each computer on a single set of speakers on a one-computer-at-a-time basis.
It also permits each computer to access any peripherals connected to the USB
ports.
Setup is fast and easy; simply plug cables into their appropriate ports. There is
no software to configure, no installation routines, and no incompatibility
problems. Since the CS72D / CS74D intercepts keyboard input directly, it
works on multiple computing platforms (PC x86 / x64, Macintosh PowerPC,
and Sun Microsystems Sparc).

technology,
There are three convenient methods to access the computers: port selection
pushbuttons located on the unit’s front panel; hotkey combinations entered
from the keyboard; and mouse port-switching – simply double-click on the
scroll wheel of a USB mouse to change ports.
There is no better way to save time and money than with a CS72D / CS74D
installation. Since a single console manages all of the computers, the CS72D /
CS74D setup: eliminates the expense of having to purchase separate console
components for each computer; saves all the space those extra components
would take up; saves on energy costs; and eliminates the inconvenience and
wasted effort involved in constantly moving from one computer to another.

([Ctrl] [Ctrl]). To change the port switching activation keys, do the following:
1. Invoke HSM (see page 13).
2. Press [X] or [x] [Enter].
Note: This procedure is a toggle between the two methods. To revert back to
the original [Scroll Lock] [Scroll Lock] method, invoke HSM, then
press and release the X key again.
Auto Scanning
The CS72D / CS74D’s Auto Scan feature automatically cycles the KVM focus
through the computer ports at regular intervals. This allows you to monitor the
computer activity without having to take the trouble of switching from port to
port manually. Although the video focus switches from port to port, th e
keyboard, mouse, and USB focus doesn’t switch. They stay at the port they
were on when Auto Scanning started. See the table below for details. .

be input. You must exit Auto Scan Mode (press the Esc key or the Spacebar)
in order to regain normal control of the console.
Video DynaSync
Video DynaSync is ATEN’s exclusive technology that eliminates boot-up
display problems and optimizes resolution when switching between ports.
To manually detect and remember monitor EDIDs, do the followin g:
1. Invoke HSM (see page 13).
2. Press [D] or [d] [Enter].
Note: If the monitor is disconnected and reconnected, the CS72D / CS74D
re-executes Video DynaSync.

and you have a Mac attached to a port, for example, you can change the port’s
keyboard operating platform configuration so that the PC compatible keyboard
emulates the Mac keyboard. The procedure is as follows:
1. Bring the KVM focus to the port you want to set.
2. Invoke HSM (see page 13)
3. Press and release the appropriate Function key (see table below). After

The Firmware Upgrade Utility
The Windows-based Firmware Upgrade Utility (FWUpgrade.exe) provides a
smooth, automated process for upgrading the KVM switch’s firmware. The
Utility comes as part of a Firmware Upgrade Package that is specific for each
device. Check the web site regularly to find the latest packages and information
relating to them at
Before you Begin
1. From a computer that is not part of your KVM in stallat ion go to our
Internet support site and choose the model name that relates to your device
(CS72D / CS74D) to get a list of available Firmware Upgrade Packages.
2. Choose the Firmware Upgrade Package you want to install (usually the
most recent), and download it to your computer.
3. Power off the CS72D/CS74D and disconnect it from your KVM
installation. Connect the 44-pin connector of the Custom KVM cable set to
the 44-pin Computer Port 1.
