USING HOTKEYS
The AdderLink XD522 units provide hotkey features to allow you to check and adjust
certain aspects of operation. Using the hotkeys you can:
• Monitor link quality using the Dashboard (see opposite),
• Choose the preferred link rate mode, and/or
• 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 AdderLink XD522
receiver, press (and release) the
(Ctrl) key three times in
succession (either of the keyboard’s Ctrl keys can be used). In
response, the three keyboard indicators will all ash, once per second.
2 Use the numeric keys 1 to 8 located above the main section of the
keyboard (not the numeric keypad), to choose the required action:
Display the Dashboard. See opposite for details.
Select Line In mode for the receiver’s analog audio input. The icon will be
displayed on screen to conrm your selection.
Select Microphone mode for the receiver’s analog audio input. The icon will be
displayed on screen to conrm your selection.
Select Low Rate (LR) mode as the preferred link speed. The icon will be
displayed on screen to conrm your selection*.
Select High Rate (HR) mode as the preferred link speed. The icon will be
displayed on screen to conrm your selection*.
Select Balanced mode (available in HR mode only). The icon will be displayed.
Allows you to share the available video bandwidth equally between two video
displays, regardless of the EDIDs being reported by them, e.g. 1920x1200 each on
video displays that would ordinarily request a native mode of 2560x1600.
Select Priority mode (default mode). The icon will be displayed. Video link 1
will take priority, allowing it to display resolutions greater than 1920x1200 (the
limit for video link 2). Appendix B shows the logic process that is applied to the
reported EDID in order to choose the most appropriate resolution.
Select High Dynamic Range (HDR10) (available in HR mode only). The icon
will be displayed. If your graphics card and monitor support 10 bit colour depth,
this will now be sent over the extension link allowing up to 1.06 billion colours to
be supported. In this mode the maximum supported video resolution is reduced
as there is now more information per pixel (also, the secondary display will be
disabled). It is not possible to support 4K video (3840x2160@30Hz) in this mode.
The bit rate remains the same at 280Mb/sec.
 Note: If you do not press any key within ve seconds, or press any key other than the digits
1 to 8 (or once you have successfully chosen an action), the keyboard will revert to normal
operation. To use another hotkey function, repeat the whole procedure described above.

Signal quality indicators for each of the
four wire-pairs within the main link cable.
Depending on the number of signal errors that
are being detected, each of the four bars will
increase in length and show a different color:
Current link rate and
video modes
Alternates every second
between showing the current
link rate and video mode.
• For the link rate: Shows
either HR for High Rate
mode or LR for Low Rate
mode. If the link is not
operating, the entry will
show

• For the video mode: BAL for
Balanced, PRI for Priority
or HDR for High Dynamic
Range.
Transmitter and receiver rmware
Displays the current rmware revisions in
both units. If the link between units is not
currently valid, the TX entry will show

The Dashboard
The Dashboard provides a quick overview of link quality as well as conrmation of the
current link rate mode and the rmware revisions of both the transmitter and receiver
units.
To display the Dashboard
• As discussed in more detail left, press
three times and then press . The
Dashboard will be shown at the top of the connected video display:
 * When changing between preferred link rates, if a rate change subsequently occurs, the
entire data link will be reset. This will cause a momentary loss of the video, audio and USB
services. A successful switch to High Rate will only be possible if the link cable is able to
support the higher rate - Please see Tips for achieving good quality links for further
information.
