Configuration
Performing an upgrade
AdderLink XD522 units are flash upgradeable using the method outlined \
here. 
The same upgrade file is used to upgrade both the transmitter and rece\
iver units 
(although they are upgraded individually). 
Warning: During the upgrade process, ensure that power is not 
interrupted as this may leave the unit in an inoperable state.
1 Download the upgrade file from Adder’s website.
2 Connect the supplied serial cable (VSC40) between your computer and th\
e 
Options port of the AdderLink XD522 unit to be upgraded.
3 Use a narrow implement (e.g. a straightened-out paper clip) to press-a\
nd-
hold the recessed reset button on the front panel until the indicators b\
egin 
pulsing.
Finding the latest upgrade files
Firmware files for the units are available from the Support > Firmware 
Updates section of the Adder Technology website (www.adder.com).
4  With the unit in download mode, transfer the upgrade file using an XMO\
DEM 
file transfer via any terminal emulator program. Use the following set\
tings: 
115200 baud, 8 bit word, no parity, 1 stop bit (8N1) and no flow con\
trol. 
5  Upon completion of the download, the unit will begin to upgrade its stor\
ed 
firmware. Once this process has completed the unit will reboot itself \
and 
begin to operate with the new firmware.
Use a straightened-out paper clip to press and hold the reset button until the front panel indicators respond
Choosing the audio input mode
The AdderLink XD522 receiver has two analog audio inputs: A microphone  
socket on the front panel and a Line In  socket on the rear. 
You can choose between these two analog inputs using a hotkey switch, as\
 
follows:
To choose between the Line In and Microphone inputs
1 Using a USB keyboard attached to one of the USB A ports on the AdderLink\
 
XD522 receiver, press the  key three times in succession. In response, 
the three keyboard indicators will all flash, once per second.
2 Use the numeric keys located above the main section of the keyboard (no\
t 
the numeric keypad), to choose the required action:
 to select Line In mode. The  icon will be displayed on screen to 
confirm your selection.
  to select Microphone mode. The  icon will be displayed on screen to 
confirm your selection. 
  The chosen socket will be patched through (via the link cable) to the \
Line 
Out socket of the transmitter.

Operation
In operation, many AdderLink XD522 installations generally require no 
intervention once configured. The transmitter and receiver units take \
care of 
all connection control behind the scenes so that you can continue to wor\
k 
unhindered. 
Front panel indicators
The six front panel indicators on each unit provide a useful guide to op\
eration:
Operating Modes
AdderLink XD522 units try at all times to maximize the data that can be \
transferred between them. The achievable throughput depends upon the len\
gth 
and quality of the cable links that join the units. Please see Tips for achieving 
good quality links. 
Video signals are most sensitive to link quality and for this reason the\
 AdderLink 
XD522 units have two modes of operation: Low Rate and High Rate. The uni\
ts 
periodically check the link quality and determine which video transfer m\
ode can 
be successfully used. The difference between the two modes is considerab\
le as 
High Rate mode can deliver over twice the video bandwidth. Please see Video 
support for details.
You can also choose which link rate mode you would prefer to use (subje\
ct to 
link cable suitability) by using the Hotkey functions - please see next page for 
details.  
On-screen icons are displayed on the video display whenever the link mod\
e 
changes, while the HR indicators on the front panels of both units continually 
show which mode is currently being used. If a rate change does occur, th\
e entire 
data link will be reset. This will cause a momentary loss of the video, \
audio and 
USB services.

IndicatorsThese six indicators clearly show the key aspects of operation:
•	A  On   Main A link is connected.   Flashes   Main A link is not connected.  Off   No power is present.
•	B  On   Optional B link is connected.   Off   Optional B link is not connected.
•	V1  On   Video port 1 is connected and receiving video.   Flashes   Video port 1 is connected but not receiving video.  Off   Video port 1 is not connected.
•	V2  On   Video port 2 is connected and receiving video.   Flashes   Video port 2 is connected but not receiving video.  Off   Video port 2 is not connected.
•	HR  On   High Rate mode is active.  Flashes  High Rate mode is preferred but cannot be established, LR mode active.   Off   Low Rate mode is active.
•	PS  On  Power connected.  Flashes  Upgrade error (other indicators show error code).  Off  No power.

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 
flash, once per second.
2  Use the numeric keys 1 to 7 located above the main section 
of the keyboard (not the numeric keypad), to choose the required actio\
n:
 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 confirm your selection.
 Select Microphone mode for the receiver’s analog audio input. The  
icon will be displayed on screen to confirm your selection. 
 Select Low Rate (LR) mode as the preferred link speed. The  icon will 
be displayed on screen to confirm your selection*.
 Select High Rate (HR) mode as the preferred link speed. The  icon 
will be displayed on screen to confirm 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 grea\
ter 
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.
  Note: If you do not press any key within five seconds, or press any ke\
y other 
than the digits 1 to 7 (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.

The Dashboard
The Dashboard provides a quick overview of link quality as well as confi\
rmation 
of the current link rate mode and the firmware revisions of both the t\
ransmitter 
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:
•	 To	remove	the	Dashboard,	press	 three times and then press .
 The Dashboard will also disappear if you select any of the other hotkeys\
. 
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 modeDisplays either HR for High Rate mode or LR for Low Rate mode. If the link is not operating, the entry will show - -
Transmitter and receiver firmwareDisplays the current firmware revisions in both units. If the link between units is not currently valid, the TX entry will show -.--  
Best quality.  Very few errors
Worst quality.  Many data errors
*  When changing between preferred link rates, if a rate change subsequentl\
y 
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.

Link cable interference protection  
While the Category rating (e.g. CAT 5e, CAT 6a, etc.) 
determines the electrical performance of a cable, another 
vital part of the overall cable specification is its protection 
from interference. As cabling distances and data rates 
increase, so too does the susceptibility to interference, 
from both external and internal sources. 
Proximity to other electromagnetic sources are the main 
external threat and these can be subdued using overall 
screening that surrounds all four of the cable pairs. 
However, interference is also possible from neighbouring 
twisted pairs within the same cable and this can be 
just as hazardous to data integrity. Such crosstalk is 
countered by shielding each cable pair separately. 
Within each Category rating, you can specify different 
combinations of external screening and internal shielding 
to suit the environment into which the link is being 
placed. Please see  the section Tips for achieving good 
quality links for suggested combinations. 
Interference protection codes
