Introduction
Overview
A KL1508Aor KL1516AKVM switch is a control unit that allows IT
administrators to access and control multiple computers from a single PS/2 or
USB KVM (keyboard, monitor, and mouse) console. A single KL1508A/
KL1516Acan control up to 8 / 16 computers. They consist of an integrated
LED-backlit LCD monitor, keyboard, and touchpad in a 1U rack-mountable
retractable sliding housing.
The similarities and differences among the models in the KL1508A/ KL1516A
series are shown in the following table:
The LCD and keyboard/touchpad modules slide independently of each other.
To maximize space in your data center, the keyboard/touchpad module slides
back to "hide away" when not in use, while the thin profile LCD monitor
rotates back – flush against the rack – allowing administrators to monitor
computer activity on the installation.
By daisy chaining up to 31 additional switches, as many as 512 computers can
be controlled from the original KVM console. An auto-sensing function
recognizes the position of each station on the chain, eliminating the need to
manually set the position, and a seven-segment front panel LED displays each
Station's position for easy identification.
Compact, high-density, RJ-45 connectors and CAT 5e/6 cable make for a
compact, efficient, wiring configuration, while the use of PS/2 and USB KVM
Adapter Cables to link to the computers, permits any combination of PCs,
Macs, Sun computers, and serial devices to coexist on the installation.
Setting up the KL1508A/ KL1516Ais fast and easy – plugging cables into their
appropriate ports is all that is entailed. Because the KL1508A/ KL1516A
intercepts keyboard and mouse input directly, there is no software to configure
and no complex installation routines.

Access to any computer on the installation is easily accomplished – either by
pressing front panel port selection pushbuttons; entering hotkey combinations
from the keyboard; or by means of a powerful OSD (On Screen Display) menu
system. A convenient Auto Scan function also permits automatic scanning and
one-by-one monitoring of the activities of selected computers.
Your KL1508A/ KL1516Ainvestment is protected through firmware
upgrades. You can download firmware update files from our website, and use
the Firmware Upgrade function to quickly and conveniently install them.
There is no better way to save time and money than with a KL1508A/
KL1516Ainstallation. By using the KL1508A/ KL1516Awith its sliding LCD
console to manage your installation, you: (1) eliminate the expense of
purchasing separate keyboards, monitors, and mice; (2) save all the space those
extra components would take up; (3) save space that a keyboard, monitor, and
mouse would take with a standard KVM switch; (4) save on energy costs; and
(5) eliminate the inconvenience and wasted effort involved in constantly
having to move from one computer to another.

Features and Benefits
The features and benefits provided by a KL1508A/ KL1516Adeployment are
described in the following table:
Features Benefits
Simple Installation and
Operation Plug-and-play installation – no software required – connecting cables is all it takes. Station positions are automatically
recognized. Computer selection via front panel switches;
hotkeys; or multi-language OSD (On Screen Display) menus.
Keyboard/Touchpad
module KVM console with 17"or 19" LED-backlit LCD monitor in a sliding housing with top and bottom clearance for smooth
operation in a 1U high rack.
Dual Rail operation – LCD monitor slides independently of the
keyboard/touchpad.
Console lock enables the sliding console to remain securely
locked away when not in use.
LED Light Exclusive LED illumination light – designed by ATEN to
illuminate the keyboard and touchpad to allow visibility in low-
light conditions.
Single Console Control Access and control up to 8 (KL1508A) or 16 (KL1516A)
computers from a single PS/2 or USB KVM (keyboard, video,
and mouse) console.
Scalability By daisy chaining up to 31 additional KL1508A/ KL1516A
switches, as many as 512 computers can be controlled from
the original KVM console – eliminating the expense of
purchasing separate peripherals for each server.
Easy Installation Setting up the KL1508A/ KL1516Ais fast and easy – plugging
cables into their appropriate ports is all that is entailed.
Because there is no software to configure, incompatibility and
configuration issues are non-existent.
Easy Operation Three port selection methods: Manual (via front panel
pushbuttons), Hotkey, and multi-language OSD (On Screen
Display).
Keyboard Language support: English (US); English (UK);
German; German (Swiss); French; Spanish; Traditional
Chinese; Japanese; Korean; Swedish; Italian; Russian;
Hungarian and Greek
Hardware Independent
Cross-Platform
Support
The KL1508A / KL1516A supports Windows 2000/XP/Vista/7,
Linux, Unix, Novell, FreeBSD, Sun, and Mac.
Space-Saving RJ-45
Connectors and Cat
5e/6 Cabling
This space-saving innovation means that the KL1508A/
KL1516Acan be conveniently installed in a 1U system rack,
and the installation can take advantage of the internal
network wiring built into most modern commercial buildings.
Reduces cable clutter for a neat and tidy data center
environment

Features Benefits
KVM Adapter Cables
to Connect to Servers
and Devices
For convenience and flexibility that allows mixing the PS/2,
USB and serial interfaces, the KL1508A/ KL1516A's design
utilizes KVM adapter cables that serve as intermediaries
between the KVM switch and the connected devices.
KVM adapter cables are available in PS/2, USB, and Serial
interfaces to support a wide variety of data center servers
and devices.
Two-Level Password
Security Supports one administrator and ten user profiles. Strong password protection prevents unauthorized accessing to the
installation – keeping your valuable data secure.
Upgradeable Firmware Stay current with the latest functionality improvements and
updates by downloading firmware upgrade files from our
website and installing them with the built-in firmware upgrade
utility.
Effortless Upgrades Simultaneous firmware upgrades to all daisy-chained KVM
switches and dongles through the daisy-chain cable.
Auto Scanning and
Broadcast Mode Auto scanning provides hands-free monitoring of selected devices at variable rates. Broadcast Mode sends commands
from the console to all computers – allowing you to perform
operations (such as software installation, upgrades,
shutdowns, etc.), on them simultaneously
Superior Video Quality Supports the video resolutions up to 1280x1024@75hz for up
to 50 meters with the new ATEN KVM Cable Adapter KA7000
series.
Multiple User Accounts Supports up to 10 user and 1 administrator accounts
Hot Pluggable Ability to add or remove components without having to power
off the KVM switch.
Adapter Cables with ID The KL1508A/ KL1516AKVM series supports automatic ID
recognition of the new ATEN KVM Cable Adapter KA7000
series (KVM Adapter Cables). Using the new adapter cables
with ID means it is not required to change cable configuration
settings when moving cables from port to port.
Device ID and attributes are stored in the adapter cables
allowing you to hot-swap port connections without having to
reconfigure attributes.
