Welcome
Introduction
Thank you for choosing one of the AdderLink X2-Series products. These 
compact modules allow you to place the controlling keyboard, video monit\
or, 
mouse and a serial device up to 300 metres (200m maximum for Gold varia\
nt) 
from a computer system. The range topping X2-Gold modules also allow you\
 to 
extend your audio accessories away from your computer.
There are three variants in the X2-Series and each consists of two modul\
es: a 
local module that attaches to your computer system and a remote module t\
o 
which the peripherals are connected. The long distance link between the \
two 
modules is made via Category 5, or higher, twisted pair cabling. 
Special circuitry within the remote module allows you to make adjustment\
s to 
the sharpness and brightness settings to suit your own preferences. Addi\
tionally, 
the X2-Silver and X2-Gold models also feature Skew adjustment to counter\
act 
the effects of uneven lengths of twisted pair cables that are used to ca\
rry the 
video signals. 
This table indicates the functional differences between the three varian\
ts within 
the X2-Series:

Installation and operation
LOCAL module switches (continued)
LOCAL Switch 1
OFF: Normal operation.
ON: (Whilst power is applied) Places the REMOTE module into password 
override mode. This allows any pre-configured passwords to be altered \
- 
particularly useful when they have been lost or forgotten. Please see th\
e 
‘Password override’ section in the ‘Special configuration’\
 chapter.
LOCAL Switch 2
OFF: Normal operation.
ON:  Set transparent mode. Use this setting if the extender modules are to be\
 
used with KVM switches that are not manufactured by Adder Technology. 
Cascaded KVM switches often use special signals to set or identify 
conditions. In transparent mode, the extender modules will pass the sign\
als 
without attempting to interpret them. 
LOCAL Switch 3
OFF: Microphone input on REMOTE module. Use this setting if a standard m\
ono-
channel microphone is connected to the MIC input on the REMOTE unit.
ON:  Stereo line-in input on REMOTE module. Use this setting if a stereo inpu\
t is 
applied to the MIC input on the REMOTE unit.
LOCAL Switch 4
OFF: Normal operation.
ON:  Suspend operation and reset the LOCAL module. Use this setting 
momentarily to produce the same effect as removing and restoring power 
if incorrect operation has occurred. Return the switch to the OFF positi\
on 
to allow normal operation to continue.
Installation
The installation of the X2-Series extender set is straightforward and ca\
n best be 
achieved in most cases by following these stages for each module:
•	 Stage	A    Check or set the configuration switch settings
•	 Stage	B    Mount the module
•	 Stage	C   Connect the cables
Stage A - Configuration switch settings
The basic operation of the LOCAL and REMOTE modules are controlled by th\
e 
banks of four switches located on the side of each module. The switches \
are 
monitored at all times and may be changed when power is on or off (the \
only 
exception to this rule is switch 1 of the LOCAL module which initiates s\
lightly 
different functions depending on the power state when it is switched).

REMOTE Switches 2 and 3
Switches 2 and 3 determine which two keyboard keys (when pressed in uni\
son) 
are to be designated as ‘hotkeys’. Hotkeys signal to the REMOTE mo\
dule that 
the next key to be pressed is a special configuration command for the \
module 
and is not to be passed to the computer system.

Stage B - Mounting a module – desk or rack
The X2-Series extender modules can be situated on a desk (or floor) \
or 
alternatively, for larger installations, mounted within optional rack mo\
unt chassis 
units.
Desk mount
Apply the supplied self-adhesive 
rubber feet to the underside of the 
module(s).
Installation Advice
•	 For	correct	operation,	the	local	and	remote	units	must	have	ground	
connections. At the computer end, ensure that the computer or KVM switch\
 
that the LOCAL module is connected to has a ground connection. At the 
keyboard/monitor/mouse end, ensure that the REMOTE module’s power 
supply is connected to a grounded power outlet. Alternatively, a ground \
connection will be made via the monitor, if the monitor is itself ground\
ed. 
•	 Try	to	avoid	laying	the	interconnect	cable	alongside	power	cables	where	
possible.
1ON423Rack mount
Note: The module switches are not accessible once it is inserted into th\
e rack, 
therefore, check all settings before insertion. 
1  Place the rack securing plate (available as a separate kit) onto the f\
ront of 
the module and secure it with the two 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. The 
rectangular cut-out in the front upper lip of the rack 
allows the two screws on the module’s upper edge to 
slide through.
4 The rack mount chassis has a series of holes in its 
floor that are spaced to accommodate the two 
screws on the module’s lower edge. Ensure that 
the screws correctly locate into the two holes of the 
chosen slot. The rack securing plate on the module 
should now be flush with the front of the rack mount 
chassis.
5 Use the third (pan-head) screw, in the top hole of the 
rack securing plate to fasten the module to the rack.

Stage C - Connections
The naming of the LOCAL and REMOTE modules relate to their proximity to \
the 
computer system. Hence, the LOCAL module connects directly to the system\
, 
while the REMOTE is at the other end of the twisted pair cable and attac\
hes to 
the keyboard, mouse, etc. 
Connections at the LOCAL module
Multi-cable connection
Most of the connections between the computer system and the LOCAL module\
 
are made via the supplied multi-cable. This has a single connection to t\
he 
module, is two metres in length and splits out to the keyboard, video, m\
ouse 
and (for the X2-Gold) microphone and speaker ports of the system.
1 Attach the 
supplied multi-
cable to the 25-
way socket at the 
end of the LOCAL 
module.
2 At the other end 
of the multi-
cable, attach 
the keyboard, 
mouse and video, 
(plus optionally 
on X2-Gold, the 
microphone and speaker) connectors to the appropriate sockets at the re\
ar 
of the computer system. On most systems the appropriate ports should be \
labelled and colour coded in a similar way to the cable connectors:
    Monitor (video)      Blue
 Keyboard     Purple
 Mouse  or  Mid green
 Speaker   or SPK  Light green
 Microphone   or  MIC  Pink (or maroon)
Serial cable connection
The X2-Series extender modules offer the option to attach an RS232 seria\
l 
device (such as a touch screen input) via the remote link. The link su\
pports 
software or hardware handshaking up to a maximum baud rate of 56Kb/s. To\
 
make the serial connection between the LOCAL module and your computer 
system, use the supplied serial link cable.
1 Attach male connector 
of the serial link cable 
to the 9 pin port on the 
LOCAL module,  
labelled .
2 Connect the other end 
of the serial link cable 
to the appropriate serial 
port of the computer 
system.

Twisted pair connection
The link between the LOCAL and REMOTE modules is made via twisted pair 
cable, specified to Category 5 or higher. Ensure that the total twiste\
d pair cable 
length (including patch boxes) does not exceed 300 metres for the Silv\
er variant 
and 200 metres for the Gold variant.  
1 Insert the connector from 
the twisted pair cable link 
into the socket marked 
‘TO REMOTE’. 
twisted pair cable connectorLOCAL
Optional power connection
The LOCAL module usually derives its power from the keyboard connection \
of 
the host system. If the keyboard connection will not be used then you wi\
ll need 
to use an external power supply of the same type used for the REMOTE mod\
ule. 
These are available from your Adder supplier.

Connections at the REMOTE module
Keyboard, video and mouse connections
The connections to the keyboard, video monitor and mouse are all made to\
 the 
sockets at one end of the REMOTE module.
1 Attach the lead from 
the monitor to the 
blue D-type socket 
labelled  on the 
REMOTE module.
2 Connect the 
keyboard lead to 
the purple mini-DIN 
socket labelled 
on the REMOTE 
module. 
3 Insert the keyboard 
lead into the green 
mini-DIN socket 
labelled  on the 
REMOTE module.
Twisted pair, power and serial connections
1 Insert the connector 
from the twisted pair 
cable link into the 
socket marked ‘TO 
LOCAL’.
2 Attach the output 
connector of the 
power supply to the 
socket at the front 
edge of the REMOTE 
module labelled 
POWER. 
3 If a serial connection is 
to be used, attach the 
lead from your serial 
device to the 9 way 
male connector on the REMOTE module labelled . 
Power supply connection
1 Insert the IEC connector of the supplied power lead into the correspondi\
ng 
socket of the power supply. Connect the other end of the power lead to a\

Audio connections (X2-Gold only)
On the X2-Gold REMOTE module, audio connections are available at the two\
 
3.5” jack sockets mounted on the side (same side as the switch bank)\
. Note: 
The microphone input (labelled ) has a dual function whereby it can either 
support a mono-channel microphone or alternatively receive stereo line i\
nput. 
Switch 3 on the LOCAL module controls the setting of this port: LOCAL sw\
itch 3 
OFF - microphone, LOCAL switch 3 ON - stereo line in. 
1 Connect the microphone 
(or stereo line input) plug to 
the REMOTE module socket 
labelled . 
Note: Ensure that the 
setting of switch 3 on the 
LOCAL module matches the 
input to this socket:  
 OFF-microphone;  
 ON-stereo line input). 
2 Connect the speaker plug 
to the socket labelled .
Note: When the X2-Gold REMOTE module 
is rack mounted, the audio connections 
must be made after the module has been 
fixed in place. Access is required to the 
rear and above the rack. Remember to 
remove the audio connections before 
attempting to slide out the REMOTE 
module.
