Making standard connections
Connections to the AdderLink AV modules do not need to 
follow the precise order given in this user guide although 
it is recommended that you do not apply power to the 
modules until all other connections have been made.
Note: Unless stated otherwise, all connection information 
given here applies to all modules in the AdderLink AV200 
family.  
Connections at the transmitter
To connect video and audio from the source PC system
1 Attach a video cable of suitable type and length (fully 
shielded with 15 way male D-type connectors at both 
ends, 2m or less - Adder part number: VSC18) to the 
socket labelled IN on the AdderLink AV transmitter.
2 Attach the other end of the video cable to the 
appropriate VGA video output socket on the source 
PC system.
3 Attach a stereo audio cable (shielded with three way 
3.5mm jack plugs at both ends - Adder part number: 
VSC22) to the socket labelled IN on the AdderLink AV 
transmitter.
4 Attach the other end of the stereo audio cable to the 
appropriate audio output socket on the source PC 
system.

To connect the link cable(s)
The links between the transmitter and receiver modules are made using be\
tween 
one and eight twisted pair cables, specified to Category 5 or higher. \
Each cable 
carries video, audio and serial communication signals to each receiver m\
odule.
When a single receiver is attached to a link cable, the maximum length o\
f that 
link cable is 300m (1000 feet).
AdderLink AV204T & AV208T models
1 Attach the connector of the first link cable to the socket labelled LINK1 on 
the AdderLink AV204T/AV208T transmitter. There should be a click when 
the cable is fully inserted and locked in place.
2 Attach the connectors of the remaining link cables to the sockets labell\
ed 
LINK 2 to LINK 4, (LINK 2 to LINK 8 on AV208T), as required.
	 In	all	cases,	there	should	be	a	click	when	the	cable	is	fully	inserted	and	
locked in place.

AdderLink AV200 transmitters and

adapters which provide a slightly 
different voltage to those used with 
other Adder products. Although the 
AV200 family power adapters appear 
to be physically identical, they are 
labelled as 5.3VDC (rather than the 
usual 5VDC). Using a standard Adder 
5VDC power supply will not cause 
damage but may affect operation.

To connect the serial port
The AV200R/AV201R receivers provide a single RS232 serial socket for use\
 with 
display control circuitry, etc. Where two connected displays both requir\
e serial 
control, a special Y-cable is available (Adder part number: VSC19).
Note: The Y-cable is supported only when the AV200R/AV201R receiver is l\
inked 
to an AV204T or AV208T transmitter. If the receiver is linked to an AV20\
0T 
transmitter, only a single display may be connected to the serial connector of the 
AV200R/AV201R receiver.
1 Attach the female connector of the Y-cable or serial device link cable t\
o the 
socket labelled  on the AdderLink AV200R/AV201R receiver.
2 Attach the other end of the serial cable (or both ends 
of the Y-cable) to the appropriate RS232 control 
socket(s) of the display(s).
 Note: The two male connectors of 
Y-cable are labelled A and B. 
These labels are important 
and identify each 
display for port 
switching purposes.

Making cascade connections
The AdderLink AV series of products have been specifically designed to\
 be 
flexible in order to support both your immediate and future needs for \
media 
streaming.	In	addition	to	the	standard	connections	made	from	transmitters	to	
receivers, you can also link extra transmitters to transmitters in order\
 to provide 
more display/speaker outputs. These non-standard links are called cascade 
connections. 
Important limitations when cascading
•	 There	should	never	be	more	than	three	cascade	connections	between	the	
primary transmitter (the one connected to the source PC) and any receiver. 
Cascade connections are possible only at the transmitter end of the link\
 
cable(s).
•	 It	is	essential	that	the	source	PC,	all	AV204T/AV208T	modules	and	all	
connected displays are configured to use the same serial communication\
 
settings (see Switch settings for details). The AV200T, AV200R and AV201R 
modules all auto-sense the serial configuration and do not need to be \
set. 
•	 Each	cascade	connection	reduces	the	overall	link	length	permissible	from	a	
transmitter to the final receiver in a branch. To calculate the recomm\
ended 
overall maximum link length for a branch, count the number of cascade 
connections between the primary transmitter and the final receiver in \
that 
branch. The effects of cascade connections on overall branch link length\
s are 
as follows:
Number of cascade connections Overall length of links for a branch 
(in a branch) (from transmitter to furthest receiver)
0  300m (1000 feet)
1 250m (800 feet)
2 200m (650 feet)
3 175m (600 feet)
Notes
 The lengths of transmitter cascade (video) connections should never be\
 
longer than 2m (6 feet) and can be considered to have a negligible eff\
ect 
upon overall link lengths.
 The maximum resolutions achievable are: 1600 x 1200 x 60Hz at 200m 
and	1280	x	1024	x	60Hz	at	300m.	If	you	are	using	lower	resolutions	then	it	
may be possible to achieve longer transmission distances than shown in t\
he 
above table although we do not recommend runs longer than 300m in any 
installation.	If	you	are	running	shorter	cables	then	it	may	be	possible	to	use	
more cascades than shown in the above table.
 Long cable lengths may induce colour separation effects. AdderLink AV201\
R 
receivers contain the necessary circuitry to minimise such effects.

Cascading transmitters
Expansion is achieved by linking 
the video, audio and serial ports of 
transmitters. The output ports of one 
transmitter are connected to the inputs 
of the next transmitter and so on. 
The RS232 serial ports of AV204T and 
AV208T transmitters can be cascaded. 
However, it is not possible to cascade 
the serial port of the AV200T, although 
its video and audio signals can be cascaded to lower 
level modules.  
Note: Ensure that there are no more than three 
cascade links between the primary transmitter and 
the furthest receiver.

To connect cascaded transmitters
1  Attach a suitable video cable between the socket

socket labelled IN on the secondary transmitter. 
(Cable specification: Fully shielded with 15 way male 
D-type connectors at both ends, 2m or less - Adder 
part number: VSC18).
2 Attach a stereo audio cable between the socket 
labelled OUT on the primary transmitter and the  
socket labelled IN on the secondary transmitter. 
(Cable specification: Shielded with three way 3.5mm 
jack plugs at both ends - Adder part number: VSC22).
3	 If	serial	connections	are	required,	attach	a	serial	
cable between the socket labelled  OUT on the 
primary transmitter and the socket labelled  IN 
on the secondary transmitter. (Cable specification: 
Shielded with 9 way D-type connectors - male at one 
end, female at the other - Adder part number: CAB-
9M/9F-2M).
4 Repeat such cascade links until the required number 
of transmitters (up to a maximum of four) are 
present. Connect the remaining signal and power 
cables to the added transmitters (and their respective 
receivers) as discussed earlier within this chapter.

Switch settings - AV204T/AV208T only
The AdderLink AV204T and AV208T transmitter modules are both equipped 
with 10-way mini switches to allow quick configuration of various item\
s. For 
normal	operation	in	the	majority	of	cases,	all	switches	should	be	OFF.	
Switch 1 is used when upgrading the internal firmware and switches 2 t\
o 10 are 
all related to various aspects of serial communications.
Note: All switch settings must be selected before power is applied.
