Introduction
The AdderLink AV range of digital signage extenders are designed and bui\
lt 
specifically for use wherever high quality video and sound must be fai\
thfully 
reproduced at distant locations. Mindful of the need for variety and fl\
exibility 
to suit disparate installations, Adder have created a family of products\
 that can 
fulfil your current requirements and be easily expanded at any future \
stage.   
Standard AdderLink AV100 models
There are three different AdderLink AV100 series transmitter and receive\
r 
module types available, the choice of each depends upon the quantity and\
 types 
of devices that need to be driven: 
AdderLink AV100 pair
The AdderLink AV100 package provides a single transmitter and single rec\
eiver 
capable of directly supporting two remote display and speaker sets. The \
transmitter can additionally support a local monitor and speaker set loc\
ated 
adjacent to the source system. Expansion is made possible by connecting \
further AV100 transmitters to the original module, each supporting their 
own AV100 receiver modules. The AV100 transmitter 
and receiver modules are also available separately and 
are known as the AV100T and AV100R respectively.
AdderLink AV104 and AV101 (or AV100)
The AdderLink AV104 transmitter and multiple AV101 modules are designed \
to provide potentially enormous expansion possibilities from the outset.\
 Each 
AV104 transmitter is capable of directly feeding up to four AV101 receiv\
ers. 
Each receiver supports two remote display and speakers sets, but additio\
nally 
can also drive a further three receivers and their 
respective displays/speakers. Additional expansion is 
also possible by connecting further AV104 transmitters 
to the original module, each supporting their own 
multiple AV101 receiver modules.

Support for DDC (Display Data Channel)
The Display Data Channel standard allows video monitors to define thei\
r 
characteristics so that the source computers to which they are connected\
 can 
optimise their video outputs accordingly. By their nature, the AdderLink\
 AV 
extenders enable multiple video displays to be attached to a single sour\
ce 
computer. This causes a complication for handling the DDC standard, howe\
ver, 
in characteristic style we have devised an elegant solution, as detailed\
 below. 
Whenever an AdderLink AV transmitter is powered on, it checks its local \
video 
port for a working display monitor with DDC information. The following s\
trictly 
ordered actions occur to automatically locate the most suitable DDC data\
: 
•	 If	a	display	monitor	is	discovered	on	the	local	video	port	of	the	transmitter,	
the DDC data are cloned from it and stored within the transmitter.
•	 If	no	display	monitor	is	discovered	on	the	local	video	port	of	the	transmitter,	
the DDC data held within the transmitter will remain unchanged.
•	 If	the	DDC	data	or	clock	lines	of	the	transmitter’s	local	video	port	are	
discovered to be connected to ground, then a default set of DDC data wil\
l 
be reloaded and used.  
After the initial search period, the stored DDC data are then presented \
to the 
video port of the source computer. When transmitters are cascaded, only \
the 
primary transmitter (the one connected to the source computer) will pe\
rform the 
search for DDC data.
AdderLink AV transmitters hold two pages of DDC data in order to support\
 the 
most advanced display monitors. The DDC data are held within non-volatil\
e 
memory so that they are retained when power is removed. 
The	manner	in	which	the	transmitters	search	for	suitable	‘DDC	donors’	
could have an impact if your installation contains display units with di\
ffering 
capabilities. Generally, you should arrange for the display monitor with\
 the 
most representative capabilities of your whole installation to be the on\
e that 
the transmitter locates on its local port, either initially (and tempor\
arily) while 
commissioning or permanently.

Further expansion
Transmitter cascading
As mentioned earlier, the AV100 
and AV104 transmitters are all 
capable of supporting additional 
transmitter modules (and their 
subsequent receivers). This is 
achieved using the video and 
audio out ports 
to provide the 
inputs into the 
next transmitter 
module, and so 
on. A limit of 
three cascade 
connections 
(comprising both 
transmitter and/or 
receiver cascades) 
is possible within 
any branch of the 
system.

Receiver cascading
This method of expansion is limited 
to the AV101 receivers as only they 
are equipped with the necessary 
LINK OUT cascade port. Using the 
LINK OUT port, the video and audio 
signals are transferred via CATx 
cabling to the next receiver. 
This receiver can then 
drive its own dual display/
speaker sets as well as 
provide a further LINK 
OUT to a third and final 
AV101 receiver. A limit of 
three cascade connections 
(comprising both 
transmitter and/or receiver 
cascades) is possible within 
any  branch  of  the  system.       
Any of the AV transmitters can be connected in cascade to provide further audio and video expansion opportunities  
The AdderLink AV101 receivers offer the further benefit of receiver cascading to provide multiple audio and video outputs on every branch

Installation
Locations
Please consider the following important points when planning the positio\
ns of 
your AdderLink AV modules:
•	 Take	care	not	to	exceed	the	maximum	link	cable	lengths	(please	refer	to	the	
section Making cascade connections). 
•	 Ensure	that	the	transmitters	are	as	close	as	possible	to	the	source	PC	system	
and the receivers are similarly close to the display modules. Use video \
connection cables that are correctly shielded and are no longer than 6m \
in 
length. 
•	 Wherever	possible,	choose	routes	for	the	CATx	twisted	pair	link	cables	that	
avoid mains power cables. 
•	 Remember	a	mains	power	socket	is	required	for	each	transmitter	and	
receiver.
•	 Consult	the	precautions	listed	within	the	Safety information section.

Using the rear mounting slot
The slot at the rear of each module allows it to be hung upon a fixed \
screw that 
protrudes from the mounting surface.
IMPORTANT: The internal circuit board is accessible through the mounting\
 slot. 
Ensure that any mounting screws protrudes no further than ½” (12.\
5mm) into 
the module casing - serious electrical damage will be caused if the scre\
w makes 
contact with the internal circuitry.

Using the self adhesive feet
Apply the supplied self-
adhesive rubber feet to the 
underside corners of the 
AdderLink AV modules. 
Mounting
Before you begin connecting to the source PC system and display devices,\
 it is 
advisable to mount the AdderLink AV modules in place. There are a number\
 of 
mounting possibilities for the transmitter and receiver modules:
•	 On	a	horizontal	surface	using	the	supplied	self	adhesive	feet,
•	 Mounted	on	a	screw	using	the	rear	slot,
•	 Within	the	optional rack mount chassis,
•	 On	inclined	surfaces	using	self	adhesive	Velcro© strips (not supplied).

Using the optional rack mount chassis
1 Place the optional rack plate onto the front of the transmitter or recei\
ver 
module and secure it with the countersunk screws. 
2	 Orient	the	module	on	its	side	so	that	its	labelled	face	is	the	correct	way	up	
and the securing plate is facing away from the rack. 
3 Slide the module into the required rack position.  
4 The rack mount chassis has a series of holes in its floor that are spa\
ced to 
accommodate	the	screws	on	the	module’s	lower	edge.	Ensure	that	the	
screws correctly locate into the holes of the chosen slot. The rack secu\
ring 
plate on the module should now be flush with the front of the rack mou\
nt 
chassis. 
5 Use the supplied (pan-head) screws, in the top hole of the rack securi\
ng 
plate to fasten the module to the rack.
