AdderLink AV100 pair
The AdderLink AV100 package provides a single transmitter and single receiver
capable of directly supporting two remote display and speaker sets. The
transmitter can additionally support a local monitor and speaker set located
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.

that need to be driven:

Standard AdderLink AV models
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 receivers.
Each receiver supports two remote display and speakers sets, but additionally
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.

The AdderLink AV range of digital signage extenders are designed and built
specifically for use wherever high quality video and sound must be faithfully
reproduced at distant locations. Mindful of the need for variety and flexibility
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.

Module mixing
Most of the AdderLink AV modules can be mixed together in various
combinations quite freely. For instance, an AV104 transmitter can drive mixtures
of AV100 and AV101 receivers. Similarly, an AV100 transmitter can control
single or cascaded AV101 receivers. An AV100 receiver can also be cascaded
from an AV101 receiver, although the reverse is not true.
However, the AV200 pair differ from the other modules because they send serial
port signals across the CATx link and so MUST NOT be cross connected (via a
CATx link) with any other non-AV200 modules. The AV200 transmitter can be
used as part of a transmitter cascade with other AV transmitter types. However,
the serial port of an AV200 transmitter cannot itself be cascaded. Therefore, if
an AV200 transmitter is involved in a cascade, it should be placed as the primary
transmitter, connected directly to the source PC system.

AdderLink AV200 pair
The AdderLink AV200 transmitter and receiver pair operate in a similar manner
to the AV100 series, with the addition of an RS232 serial port. The serial port
of the source PC is presented at the AV200 receiver for use by a remote device
such as a touch screen terminal. The AdderLink AV200 models are designed
primarily for single point to point operation although
they can provide further video/audio expansion via
transmitter cascade connections (the serial
connection is not expandable).

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

AV101 receiver. A limit of

Please consider the following important points when planning the positions 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.

receiver end (AV101 modules only) or at a mixture of both.
• The RS232 serial port of an AdderLink AV200 transmitter cannot be
cascaded, therefore, if an AV200 transmitter is involved in a cascade, it
should be placed as the primary transmitter, connected directly to the source
PC system.
• Each cascade connection reduces the overall link length permissible from a
transmitter to the final receiver in a branch. To calculate the recommended
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 lengths are

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 and/or receivers to
receivers in order to provide more display/speaker outputs. These non-standard
links are called cascade connections.

To place the AV200 receiver into skew compensation mode
NOTE: This procedure is not required for the AV101 receiver.
The AV200 receiver module shares one of its processors between the duties of
operating its serial port and adjusting the skew compensation. When power
is first applied to the module, it enters a neutral state for up to ten seconds
signified by a fast flickering red indicator. During this time, if you move one of
the skew dials, the module will enter skew mode.
1 Apply power to the AV200 receiver module. The red indicator should flicker
rapidly for up to ten seconds.
2 Using a small screwdriver, rotate one of the skew dials slightly. The
red indicator should flash slowly signifying that the module is now in
skew compensation mode. Continue to make your skew compensation
adjustments in the usual manner - see opposite.
3 Once the necessary adjustments have been made, remove power from the
module for a few seconds and then reapply. The module will automatically
settle into its default serial port mode after ten seconds.

To adjust the skew compensation
Your chances of achieving a successful skew compensation adjustment will be
improved if you do the following:
• Ensure that you have a clear view of one or both display screens,
• Display a suitable RGB test pattern, either the supplied pattern or a selfcreated version,
• Use a screwdriver of an appropriate size to adjust the dials,
• Begin with both skew dials in their neutral positions - if the module has
been previously used and skew adjusted for an alternative installation, zero
the dials as described in the section ‘To zero the skew adjustment dials’ left.
NOTE: AV200 receiver modules must be placed into skew compesation
mode - see opposite.

To zero the skew adjustment dials
When supplied, the two skew dials are set in
their neutral positions. i.e. no delay to either

been previously used and adjusted then you
may need to relocate the zero point. There are
no setting markers around the two skew dials
and the dial itself does not have a pointer.
1 Insert a small screwdriver into the skew
dial and twist it all the way anticlockwise.
Note the position of the dial when it
reaches its end point.
2 Rotate the screwdriver fully clockwise and
Max

Further information
Video image at the receiver module is distorted or shadows appear to
the right of displayed objects.
Adjustments are required to compensate for the length of the twisted pair cable
being used. If video problems persist:
• Please refer to the ‘Brightness and sharpness adjustments’ section in the
‘Operation’ chapter.
• If the overall video image is ‘fuzzy’ and/or has coloured shadows you may
need to make skew adjustments (AdderLink AV101 receivers only). This
procedure allows you to finely tune the red, green and blue video signal
timings to overcome most colour separation problems. Please refer to the
‘Skew compensation adjustment’ section in the ‘Operation’ chapter.
