Power and activity indicators
Each	module	provides	two	indicators	to	confirm	power	status	and	also	feedback	about	
the various input signals:   
GENERAL USE
In use, the X-DVIPRO-DL modules should be transparent - the system and its 
peripherals should operate exactly as normal, the only difference being that they are now 
up to 50 meters apart. 
Video display (EDID) information
Extended	Display	Identification	Data	(or	EDID)	is	an	industry	standard	scheme	which	
allows video displays to declare their capabilities to the computer’s video adapter 
circuitry, allowing the latter to optimize their outputs accordingly. Since the widespread 
adoption of the scheme, video adapters have become increasingly dependent on receiving 
relevant EDID information during start-up, before they will output anything more than a 
rudimentary video signal.
Each time that the remote module is powered on, it attempts to read the EDID 
information from the connected DVI video monitor. If the attempt is successful, the 
information is transferred to the local module and stored within non-volatile memory. 
This information is then made available to the computer’s video adapter when required.
HDMI 1.3a operation
Using optional HDMI to DVI converter cables (Adder part number: VSCD11), the 
AdderLink X-DVIPRO-DL can support HDMI video and audio up to the 165MHz clock 
rate (1920 x 1080 at 60Hz, 24-bit color). 
Eight channels of HDMI audio are supported with sample sizes of 16, 20 or 24-bits at 
32KHz,	44.1kHz, 	48kHz,	88.2kHz, 	96kHz,	176.4kHz, 	or	192kHz	(simultaneously	with	the	
jack audio).
Note: The High-bandwidth Digital Content Protection (HDCP) and Consumer Electronics Control 
(CEC) schemes are not supported.

TROUBLESHOOTING
If you experience problems when installing or using the X-DVIPRO-DL modules, please 
check through this section for a possible solution. If your problem is not listed here and 
you cannot resolve the issue, then please refer to the Getting assistance section.
No video image is displayed on the remote monitor
•	Check the yellow indicators on the local and remote modules while no keys are 
pressed on the keyboard and no mouse movements are being made:
 
LOCAL:	If	the	yellow	indicator	is	flashing*, 	then	the	video	feed	to	the	local	module	is	
not valid. Try connecting a DVI monitor (preferably using the same DVI link cable as 
used with the local module) directly to the computer and check for a correct image.
 
REMOTE:	If	the	yellow	indicator	is	flashing*, 	then	the	video	feed	via	the	link	cable	is	
not valid. If the link cable is long, try using a short link cable temporarily to check for 
basic operation. 
 
If the yellow indicators are off, then the link cable is not properly connected.
•	Check that both the local and remote ends of the extender are X-DVIPRO-DL 
variants. The single link X-DVIPRO modules are not compatible with X-DVIPRO-DL.
Only single link resolutions are displayed
•	Check that the video cables connected to the local and remote modules are both 
specifically	dual link types. 
Video blanking is occurring on the remote display screen
•	Check that the correct type and length of link cable is being used. Please see the cable 
advice given on page 2 and also in Appendix A.  
 
*	Take	care	not	to	confuse	the	flash and blink codes used by the yellow indicators:
•	A flash is when the yellow indicator shows a regular on/off cycle every second, to 
warn that there’s a video feed problem.
•	A blink	is	when	the	yellow	indicator	is	mostly	on	with	short	off	periods, 	to	confirm	
that a valid dual link video signal is present.

APPENDIX A  - Cables for use with digital extenders
Introduction
The demands of extending high resolution DVI and HDMI digital video signals are 
considerable and mean that it is not possible to use Cat5e cabling to ac\
hieve the 
maximum extension distance of 50 meters. The large video bandwidth involved means 
that to achieve the best possible performance from digital extenders, it is vital that the 
correct cabling is chosen.
There are three important factors to consider when choosing a cable for use with digital 
extenders.
IMPORTANT:  Please remember that even though they use network-style 
cables, the link ports of the modules are NOT Ethernet ports and must not 
be connected to network switches or any other devices.
Types of cable 
Twisted pair cables can have either solid or stranded conductors. Solid cables come 
in bulk spools and are often referred to as infrastructure or bulk cabling. They are less 
flexible	than	stranded	cables	but	have	less	attenuation.	These	cables	are	typically	run	
throughout a building and terminate at the rear of a wall plate.
Types of RJ45 connector
For each type of cable there is also an associated RJ45 connector. It is important that the 
correct type of connector is used for the type of cabling.
Insulation displacement RJ45 connectors are designed to work with solid conductor cables 
while insulation piercing RJ45 connectors are designed to work with stranded conductor 
cables.
Stranded cabling is found in patch cables and is intended to connect the front of the wall 
plate	to	the	extender	or	computer	using	RJ45	connectors. 	They	need	to	be	more	flexible	
because the cabling gets disconnected and connected constantly. 
For a digital extender application, solid conductor cables give a better performance as 
these allow for a higher bandwidth and have less attenuation. Ideally a thickness of 22 
AWG should be used.
SolidStranded
The teeth of the insulation displacement connectors are designed to straddle and hug 
the sides of the solid center conductor of the cable. 
The teeth of the insulation piercing connectors penetrate the middle of the cable and 
nest in between the stranded wires. If insulation piercing connectors are used on solid 
core cable then the connection will not be stable as the teeth will try to but are unable 
to penetrate the solid center conductor. The teeth will then slide off the solid core and 
not make a stable contact.
Types of shielding
The	third	and	final	factor	in	determining	the	cable	to	be	used	in	digital	extension	is	
shielding. The shielding protects the cable from two types of interference, internal 
crosstalk and external interference. Internal crosstalk is the interference between the 
different pairs inside the cable. External interference is any interference that comes from 
outside the cable. This is caused by many things; proximity to mobile phones, bundling 
cables	together	or	running	them	over	lighting	fixtures.
Internal crosstalk is most detrimental to digital extension as the signals cannot b\
e 
recovered after experiencing crosstalk. You are left with a black screen. 
The most common type of shielding is Screened/Unshielded Twisted  Pair (S/UTP). This  has 
an overall shield and will protect the signal from external interference. However it does 
not provide any protection from crosstalk.
The next type of shielding is Shielded Twisted  Pair (STP). This has four individual shields, 
one for each data pair. This is good for protecting the signal from internal crosstalk but 
does not provide an overall shield to protect against external interference.
If you combine the two types of shielding together you have Screened/Shielded Twisted  Pair 
(S/STP). This is also sometimes referred to as Shielded/Foil Twisted  Pair (S/FTP). This has four 
individual shields, one for each pair and an overall shield. S/STP is the best cable to protect 
against	any	interference	and	is	the	cable	choice	to	be	used	for	digital	KVM	extension.
