ii.....The Avocent® LongView™ 5000 Series High Performance KVM Extender System Installer/User Guide

Product Overview
The Avocent®LongView™ 5000 series high performance KVM extender system is a DisplayPort KVM
extender that enables you to locate your critical computing hardware in a secure and temperature controlled
environment away from the user workstation while maintaining the same user desktop experience. Using
either one or two CATx cable links you can achieve separation distances of up to 150 meters/492 feet
between the transmitters and receivers. At such distances the units can transfer high resolution DisplayPort
video, USB 2.0 (low/full and hi-speed), digital and analog audio plus RS-232 serial.
Features and Benefits
Video support
The LongView™ 5000 extender system provides the highest possible video bandwidth between the
transmitters and receivers. To allow for the differing grades of CATx links, the extender system periodically
checks the quality of the link and can accurately determine which of the two video transfer modes can be
supported. In low rate mode, the local and remote extender units may be placed up to 492 feet (150 m) apart.
The units actively monitor video link quality and at link distances of less than 328 feet (100 m). High rate mode
provides a second video port and more than twice the video bandwidth capability. In high rate mode, there is
enough video bandwidth to support a single high resolution 2560 x 1600 display or two 1920 x 1200 displays
(at 60 Hz refresh) or even 4K video, 4096 x 2160 (at 30 Hz refresh, single display).
EDID management
The extender system intelligently manages the EDID (Extended Display Identification Data) information that
each video display provides before reporting to the host computer. If sufficient bandwidth does not exist for
the modes declared by the second display, it is not reported to the host computer.
USB support
A wide range of USB devices are supported on the receiver via the four ports on the front of the unit. Three of
the ports support low/full speed (version 2.0) USB for keyboards and mice. The fourth port provides hi-speed
(version 2.0) USB with transfer rates up to 80 Mbits/sec and supports mass storage and isochronous devices.
NOTE: Availability of the fourth USB port depends upon the use of CATx link B cable which is used for the
transport of hi-speed USB signals.
Audio support
The LongView extenders can transfer analog and digital audio signals across the CATx cable link. Standard
analog audio is supported through 3.5 mm jacks on the transmitters and receivers. Additionally, the line-in jack
on the transmitter and the line-out jack on the receiver are dual purpose. They can accept either 3.5 mm
analog jacks or mini-TOSLINK optical fiber connectors.

Serial support
The transmitters and receivers each have serial options ports which are used for firmware upgrades. The ports
can also be used for transferring high speed serial data across the CATx link.

Front Panel Indicator Descriptions
Operating modes
The LongView extenders maximize the data that is transferred between them. The achievable throughput
depends upon the length and quality of the cable links that join the units.
Video signals are most sensitive to link quality and for this reason the extenders have two modes of operation:
low rate mode and high rate mode. The extenders periodically check the link quality and determine which
video transfer mode can be successfully used. The difference between the two modes is considerable as high
rate mode can deliver over twice the video bandwidth. You can also choose which mode to use by using the
Hotkey functions. For more information, see Using hotkeys on page 7.
When the link mode changes, on-screen icons are displayed, while the indicators on the front panels of both
units show which mode is currently being used. If a rate change occurs, the entire data link is reset causing a
momentary loss of the video, audio and USB services.

Basic Operation
The Options port on the rear panel of every extender operates as a serial connection that can either:
•Be used to update the firmware of the unit
•Provide an RS232 serial connection that is passed between the transmitter and receiver.
When the extenders are not in upgrade mode, they can be used to transfer serial data between them at rates
up to 115200 baud. When serial devices are attached to the options ports on the transmitter and receiver, the
units transparently convey the signals between them and no serial configuration is required.
Upgrades
The LongView™ extenders are flash upgradeable. The same upgrade file is used to upgrade both the
transmitter and receiver units, but are upgraded separately.
WARNING: During the upgrade process, ensure that power is not interrupted as this may leave the unit in
an inoperable state.
To upgrade the extenders:
1. Download the upgrade file from http://www.emersonnetworkpower.com/en-US/Support/Software-
Downloads/kvm-switches/KVM-Extenders/Pages/default.aspx.
2. Connect a serial cable between the computer and the options port of the extender to be upgraded.
3. Using a straightened-out paper clip, press and hold the recessed reset button on the front panel until the
indicators begin pulsing.
4. With the unit in download mode, transfer the upgrade file using an XMODEM file transfer via any
terminal emulator program. Use the following settings: 115200 baud, 8 bit word, no parity, 1 stop bit
(8N1) and no flow control.
After the download completes, the extender firmware is upgraded. Once this process is complete, the unit will
reboot.
Receiver
Video display connections
Two DisplayPort ports are provided on the rear panel of the transmitters. When using high resolution video
displays, it is important that the video bandwidth requirements are within the capabilities of the port to which
they are attached. The bandwidth available on the two ports on the receiver unit can be different and are
greatly affected by the mode in which the extender system is running. Please see the release notes for details
about which high and low rate modes and resolutions are supported.
The link capacity between the transmitter and receiver is checked periodically to determine which rate mode
can be supported. The checks are generally performed when the units are powered on, when the main CATx
link is established, if cables are disconnected or if the CATx link is lost. See Using hotkeys on page 7 for
information on selecting the rate mode.

Support for other video standards
Both ports support the DisplayPort Dual-Mode (DP++) standard, which means that as well as providing high
resolution DisplayPort signals, they can also sense when a single-link HDMI or DVI adaptor is attached.
When this occurs, the output signals are adjusted accordingly to support those display types. Additionally, a
dual-link DVI adaptor can be attached (to port 1 only), which provides higher resolution signals for special DVI
displays. Some adaptors use power from the video socket whereas others require an external power supply,
and this is usually gained from a spare USB socket. Port 1 provides a higher bandwidth than port 2 which is
limited to a maximum of 154 Mpixels/per second. Single-link DVI can require up to 165 Mpixels/per second.
EDID management
The extenders mask the resolution modes that cannot be supported within the available bandwidth. The
display attached to Video port 1 is given the priority. If sufficient bandwidth does not exist for the modes
declared by the second display, it is not reported to the host PC. EDID information is checked when a new
monitor connection is sensed and it is passed to the computer.
USB connections
The receiver provides four USB ports on the front. Three ports are labeled for low/full speed USB keyboards
and mice only. These are also suitable for providing power to third-party DisplayPort adaptors. The fourth port
is the hi-speed USB port which provides the following:
•One of the host computer USB ports is connected to the Link B port on the transmitter and supports
USB version 2.0.
•The second CATx Link B is in place.
Link connection
Transmitters and receivers are linked by either one or two CATx cables at a distance of up to 150 meters (492
feet). The type and quality of the CATx cables used are crucial to the mode of operation. If a hi-speed USB is
not needed at the receiver, a CATx link between the B ports of the units is not required.
Audio connections
The receiver has two analog audio inputs, a microphone input on the front panel and a line-in input on the rear
of the receiver. You can choose between these two analog inputs using a hotkey switch.
To choose between the line-in and microphone inputs:
1. Using a USB keyboard attached to one of the USB A ports on the receiver, press CRTL three times.
The three keyboard indicators will all flash, once per second.
2. Use the numeric keys to select the required input.
NOTE: Do not use the numeric keypad.
To select line-in mode, press 2. The line-in icon is displayed on the screen to confirm your selection.

To select microphone mode, press 3. The microphone icon is displayed on the screen to confirm your
selection.
The selected input is patched through, via the link cable, to the line-out jack of the transmitter.
Power connection
Each receiver is supplied with a 20 W power adaptor. There is no on/off switch on the unit, so operation begins
as soon as a power adaptor is connected.
Using hotkeys
The LongView™ extenders provide hotkey features to allow you to check and adjust certain aspects of the
operation as follows:
•Monitor link quality using the dashboard.
•Choose the preferred link rate mode.
•Choose between line-in and microphone modes at the receiver.
To use hotkeys:
1. Using a USB keyboard attached to one of the USB A ports on the receiver, press CRTL three times.
