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.
The three keyboard indicators will all flash, once per second.
2. Use the numeric keys 1 to 7, located above the main section of the keyboard to select the required
action.
