Introduction
Overview
A KH1508A / KH1516A / KH1532A KVM 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 KH1508A /
KH1516A / KH1532A KVM switch can control up to 8 / 16 / 32 computers.
By daisy chaining up to 31 additional switches, as many as 1024 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, J-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 KH1508A / KH1516A / KH1532A is fast and easy – plugging
cables into their appropriate ports is all that is entailed. Because the KH1508A
/ KH1516A / KH1532A 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 KH1508A / KH1516A / KH1532A investment 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 KH1508A /
KH1516A / KH1532A installation. By allowing a single console to manage up
to 1024 computers, you: (1) eliminate the expense of purchasing separate
keyboards, monitors, and mice; (2) save space; (3) save on energy costs; and
(4) eliminate the inconvenience and wasted effort involved in constantly
having to move from one computer to another.

Single Console Control Access and control up to 8 (KH1508A) or 16 (KH1516A) or 32
(KH1532A) co puters fro a single PS/2 or USB KVM
(keyboard, onitor, and ouse) console.
Scalability By daisy chaining up to 31 additional KH1508A / KH1516A /
KH1532A switches*, as any as up to 1024 co puters can
be controlled fro the original KVM console – eli inating the
expense of purchasing separate peripherals for each server.
Note: If you wish to include KH1532A into your daisy chain,
you ust have a KH1532A as the first station.
Easy Installation Setting up the KH1508A / KH1516A / KH1532A is fast and
easy – plugging cables into their appropriate ports is all that is
entailed. Because there is no software to configure,
inco patibility and configuration issues are non-existent.
Easy Operation Three port selection ethods: Manual (via front panel
pushbuttons), Hotkey, and ulti-language OSD (On Screen
Display).
Multi-language keyboard support includes English (US / UK),
French, Ger an, Japanese, Korean, and Traditional Chinese.
Hardware Independent
Cross-Platfor
Support
The KH1508A / KH1516A / KH1532A 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 eans that the KH1508A /
KH1516A / KH1532A can be conveniently installed in a 1U
syste rack, and the installation can take advantage of the
internal network wiring built into ost odern co ercial
buildings.
Reduces cable clutter for a neat and tidy data center
environ ent.
KVM Adapter Cables
to Connect to Servers
and Devices
For convenience and flexibility that allows ixing the PS/2,
USB and serial interfaces, the KH1508A / KH1516A /
KH1532A's design utilizes KVM adapter cables that serve as
inter ediaries 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.

website and installing the with the built-in fir ware upgrade
utility.
Effortless Upgrades Si ultaneous fir ware upgrades to all daisy-chained KVM
switches and dongles through the daisy-chain cable.
Auto Scanning and
Broadcast Mode
Auto scanning provides hands-free onitoring of selected
devices at variable rates. Broadcast Mode sends co ands
fro the console to all co puters – allowing you to perfor
operations (such as software installation, upgrades,
shutdowns, etc.), on the si ultaneously.
Superior Video Quality Supports video resolutions up to 1920 x 1200 @ 60 Hz up to
30 eters, 1600 x 1200 @ 60 Hz up to 40 eters, and 1280 x

*With the KVM adapter cable KA7000 series.
Multiple User Accounts Supports up to 10 user and 1 ad inistrator accounts
Hot Pluggable Ability to add or re ove co ponents without having to power
off the KVM switch.
Adapter Cables with ID The KH1508A / KH1516A / KH1532A KVM series supports
auto atic ID recognition of the new ATEN KVM Cable
Adapter KA7000 series ( KVM Adapter Cables). Using the
new adapter cables with ID eans it is not required to change
cable configuration settings when oving cables fro 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.

Port LEDs:
 An On Line LED lights green to indicate that the co puter
attached to its corresponding port is up and running. A
flashing LED indicates that the Port is being used for
cascading to another switch.
 A Selected LED lights orange to indicate that the co puter
attached to its corresponding port is the one that has the
KVM focus. The LED is steady under nor al conditions, but
flashes when its port is accessed under Auto Scan ode
(see F7: SCAN, page 38, for auto scan details).

5 fir ware
upgrade port
The fir ware upgrade cable that transfers the fir ware
upgrade data fro the ad inistrator's co puter to the
KH1508A / KH1516A / KH1532A (see page 54), plugs into this
RJ-11 connector.
6 power LED Lights to indicate that the KH1508A / KH1516A / KH1532A is
powered and ready to operate.
7 station ID
LED
The KH1508A / KH1516A / KH1532A’s station ID is displayed
here. If this is a single station installation (see page 14), or the
first station on a daisy chained installation (see page 16), the
KH1508A / KH1516A / KH1532A has a station ID of 01.
On a daisy chained installation, the KH1508A / KH1516A /
KH1532A auto-senses its position and displays the station ID
