The Avocent AMX® switch is a KVM (keyboard, video and mouse) switch that allows users to
access multiple system servers or serial devices from a single keyboard, monitor and mouse.
Multiple users in different locations can share access to PC, USB or Sun servers and serial devices.
A typical AMX switching system consists of one or m
Avocent matrix intelligent (IQ) modules. Up to three tiers of AMX switches can be cascaded to
provide seamless access to a large number of target devices. Other KVM switches, including
Avocent and non-Avocent branded, may also be attached in a cascaded system but do not provide
seamless cascading.
All AMX switches are rack mountable and are equipped with the Avocent patented OSCAR
graphical user interface and the AMWorks

Features and Benefits
Internet Protocol (IP) support
The AMX switch series supports IPv4 (default) and IPv6 functionality.
Multiplatform
With the AMX switching system, you can access any combination
serial devices using a single keyboard and mouse.
Connection sharing
Two or more users can share access to the same target device simultaneously through
switch. When sharing a connection to a target device, all users see the video but only one user at a
time controls the keyboard and mouse.
Security
The AMX KVM switching system allows you to house valuable equipment in controlled areas.
IQ modules, compact devices that eliminate cable bulk, prevent
device through cable manipulation. You can control user access by assigning rights to each
username for specific target devices. Administrative privileges, usernames and the serial port are
also password-protected.

entication will be enabled if your AMX switch supports LDAP.
Advanced video compensation
The AMX user stations and IQ modules provide advanced vide
o compensation that automatically
maximizes video quality for long distance communications. You can also manually adjust video
quality for specific servers or user stations.
Scalable architecture
The AMX switching system scalable architecture can easily accommodate additional servers
and
users. IQ modules, user stations and switches are pre-assigned unique identification numbers
(UIDs), allowing you to easily reconfigure the switching system. Name changes to IQ modules are
automatically sent to all attached user stations, even if the units are on different networks.
Audio and serial support
You can use the AMX switching system to access audio and s
erial data from connected target
devices. To access this feature, the AMX switching system must include multimedia-capable
devices and a user station and IQ module that support audio and serial emulation.
Extended keyboard and mouse support
You can use a variety of keyboards and mouse peripherals
to access any target device in the AMX
switching system. Most user stations support PS/2 and USB keyboard and mouse types. Some user
stations support PS/2 multimedia keyboards. Pinnacle FAK (Fast Action Keyboard) and Chyron
Duet keyboards are supported on AMX 5120, AMX 5121 and AMX 5130 user stations, and Devlin
Vizrt keyboard is supported on AMX 5111, AMX 5121 and AMX 5130 user stations.
Broadcast configurations with nVisionrouter control
In AMX switching system broadcast configurations, stud
io operators can use Pinnacle FAK or
Chryon keyboards and have access to Deko, Chyron CG and other machines used for delivery of
live content. Editing suites have access to Avid, SGI and storage machines with full media
provided from these machines through an AMX switch and nVision router combination. Broadcast
engineers have full access to all servers and equipment to provide maintenance and support. In
addition, all valuable equipment is secure and housed in a safe environment.
Connecting an nVision router to the AMX switching system provides video and audio ro uting
functio
nality to users. When a user in the AMX switching system connects to a target device, the
nVision router will automatically connect the audio and video signals from the target device to the
user’s workstation.
Seamless cascading

switching system. You can connect target devices to up to three levels of AMX or non-Avocent
KVM switches. When cascading AMX switches, you can seamlessly connect to any target device
from a single list in the OSCAR interface, as if all the target devices were connected to one switch.
You can also cascade non-Avocent KVM switches, but to access the attached target devices you
must first select the non-Avocent switch from the OSCAR interface target list, and then connect to
the target device using the methods provided by the non-Avocent KVM switch.
Redundancy and scalability
You may connect two AMX matrix switches to a single user station to allow redundancy and fault
tole
rance. If one of the AMX switches has a power failure, the second switch provides an alternate
path to access the same set of target servers. In addition, you can extend your user station access to
additional target servers connected to a second AMX switch.
OSCAR graphical user interface
With the OSCAR graphical user interface, you can use your keyboard or
attached target device. This easy-to-use, menu-driven interface also enables you to administer
security settings, language and keyboard selection, hotkey sequences and other features.
