Product Overview
Features and Benefits
The Avocent LongView®Wireless extender connects Keyboard, Video, Mouse (KVM) and audio
peripherals wirelessly to your computer, from up to 100 feet away. The LongView Wireless
extender is a digital system that processes analog video, inbound and outbound, utilizing a unique,
proprietary compression engine. At the heart of the compression engine is a multimedia DSP and
an FPGA that are coupled to an IEEE 802.11a radio board.
Its industry standard design makes the LongView Wireless extender compatible with virtually any
PC, display technology and operating system. Installation is essentially Plug and Play requiring no
new drivers or software.

The LongView Wireless receiver
The LongView Wireless receiver connects directly to your user interface devices (keyboard, video
monitor and mouse) and serves as the radio interface device for these components. It receives audio
and video data from the source computer and sends keyboard and mouse data from the user
interface devices to the source computer. The LongView Wireless receiver has five chassis-
mounted connectors for video, keyboard, mouse and audio peripherals and power. Power is
supplied to the transmitter from a universal input 12 V DC switching power supply (included).
Compatibility with Peripherals
The LongView Wireless extender is compatible with the following peripherals:
• Keyboard - The LongView Wireless transmitter and receiver support virtually any standard
PS/2 keyboard.
• Mouse - The LongView Wireless transmitter and receiver support 2-button PS/2 mice. Mice
that have more than two buttons work with the reduced functionality of a 2-button mouse.
• Video - The LongView Wireless extender supports VGA, SVGA and XGA resolutions up to
60 Hz refresh rate. Both CRT and LCD monitors with standard 15-pin high density connectors
are supported.
• Audio - Speakers and headphones with 3.5 mm audio plugs are supported on the receiver side
of your LongView Wireless extender, provided the transmitter has been connected to the sound
card of your PC with the provided audio cable.
Safety Precautions
To avoid potential video and/or keyboard problems when using Avocent products:
• If the building has 3-phase AC power, ensure that the computer and monitor are on the same
phase. For best results, they should be on the same circuit.
• Use only Avocent-supplied cable to connect computers and KVM switches. Avocent
warranties do not apply to damage resulting from user-supplied cable.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe the
following precautions:
• Do not use a 2-wire extension cord in any Avocent product configuration.
• Test AC outlets at the computer and monitor for proper polarity
and grounding.
• Use only with grounded outlets at both the computer and monitor. When using a backup
Uniterruptible Power Supply (UPS), power the computer and the LongView Wireless
transmitter unit off the supply.
NOTE: The AC inlet is the main disconnect.
