If you have purchased the TPA110 IRT / IRR model, this also permits passing of
an IR (infrared) signal and will provide you with visual indication of the correct
incoming video signal.
Also, a dry contact (VIDEO) indicates that the correct incoming video signal is
present. This can be useful for remote monitoring of the condition of the incoming
video signal (present or alarm).
Transmission of the IR signal permits remote control using an IR remote control
from one environment of a unit located in another environment .
To do this, an external IR receiver will be connected to the TPA110 IRR and an IR
emitter to the TPA110 IRT or vice versa.
This permits bi-directional but not simultaneous IR transmission.

To do this, you need:
-an amplified external IR receiver normally installed on a wall and connected to
the IR IN terminals of the TPA11 IRT or TPA11 IRR;
-an IR emitter which will be connected to the IR OUT jack of the TPA11 IRR or
TPA11 IRT.
The IR emitter will be positioned on the front of the appliance to be controlled
(DVD player, Satellite etc.).
For other information regarding connection of IR devices, refer to paragraph 4.5

4.0 INSTALLATION
In a typical installation, the e a e usually 2 independent video sou ces to be
di ected towa ds two destinations. A CAT5 cable is used fo t ansmission between
the t ansmission and eceiving units. The CAT5 cable is the standa d cable used
fo local compute netwo ks and consists of fou unshielded twisted pai s (UTP).
The maximum lengths of the CAT5 cable that can be compensated a e:
-375mt. fo cable type AWG26
-500mt. fo cable type AWG24
-650mt. fo cable type AWG22
For monitoring and signal present type applications, sections of up to 900mt of
AWG22 CAT5 cable can be used.
In c itical noise conditions, in o de it imp ove the all- ound pe fo mance of the
system, the CAT6 cable can be used.
WARNING
Pay particular attention to grounding
of the sources and destinations (see par. 4. )

4.5 IR (Infrared) SIGNAL connection
Usually, IR transmission is used to control an appliance (DVD player, Satellite,
etc.) located close to the transmitting unit, from the receiving station using a
remote control.
However, the circuitry used in the dual TPA110 IRT/ IRR also permits a reverse
path. Transmission may therefore be bi-directional but not simultaneous.
WARNING
If two users transmit an IR signal concurrently from the receiving and
transmitting station, a line conflict occurs and the transmissions will fail.
4.5.1 IR RECEIVER connection
The IR receiver is an electronic device able to transform IR light impulses emitted
by a remote control into an electrical signal.
The IR receiver must be positioned so that can be easily reached by the IR beam
emitted by the remote control. It is usually installed on a wall at medium-high
height. When installing the IR receiver, always comply with the manufacturer's
instructions regarding:
-Sensitivity
-Exposure to environmental and sunlight
-Settings and calibration
WARNING
Amplified IR receivers must e used
When selecting the IR receiver, the user must pay particular attention to the
operating frequency of the remote control whose signal is remotized.
Most remote controls operate at low frequencies but some manufacturers (Bang &
Olufsen, enwood, Pioneer) use remote controls with carrier frequencies of up to
1,125MHz.
WARNING
Make sure that you uy an IR receiver
that is compati le with the frequency of the remote control.
The TPA110 IRT / IRR are compati le with
frequencies of up to 1.2MHz

The IR receivers available on the market are of the 3-wire type: Positive (+), ND
(0 Volt) and SI NAL.
Connect the IR receiver to the
terminals of the TPA110 IRR / IRT
unit marked IR IN +12, GND and
SIG. If the cable leading out of the
receiver is fitted with a 3.5 mm
stereo jack, cut the cable and identify
the three wires to be connected to IR
IN +12, GND and SIG terminals of
the TPA110 IRR / IRT.
For identification of the pin-out of
the receiver, refer to its user
manual.
Most of the receivers on the market
have a power SI NAL output, i.e.
able to drive an IR transmitter IR
directly. In this case, no setting is
required on the TPA110 unit as it is
factory set for this type of interface.
If the IR receiver has a SI NAL output at TTL level, the TPA110 IRR / IRT unit
must be set as described in paragraph 3.0
WARNING
If available, use of IR receivers with TTL output
ca be recomme ded as they co sume less a d cost less
4.3.2 Connection of the IR (Infrared) EMITTER
The IR emitter is an optical device able to transform en electrical signal into a
beam of IR light.
The IR emitter usually consists of a plastic capsule with a cable leading out of this
terminated with a 3.5 mm mono jack.
The capsule in which the infrared light emitter led is embedded must be
positioned, using transparent adhesive tape, on the front of the appliance to be
controlled.

5.0 VIDEO AND AUDIO SIGNAL EQUALIZATION
The CAT5 cable introduces considerable losses on the signal in transit.
A 100-meter long AWG26 CAT5 cable attenuates 50% of the color com onents
of the video signal. As the com osite video signal is a com lex signal that does
not acce t downgrading, for each installation calibration must be erformed in
order to offset cable losses. The unit that makes this com ensation is the
receiving unit, in our case the TPA110 R / IRR.
WARNING
The TP110R / IRR unit is p ecompensated fo 50 mt of CAT5 cable
Howeve , use of a cable with a length of less than 50mt
does not affect system functioning.
The maximum lengths of the CAT5 cable that can be com ensated are:
-375mt. for cable ty e AWG26
-500mt. for cable ty e AWG24
-650mt. for cable ty e AWG22
For monitoring and signal resent ty e a lications, sections of u to 900mt of
AWG22 CAT5 cable can be used.
In critical noise conditions, in order it im rove the all-round erformance of the
system, the CAT6 cable can be used.
The CAT6 cable has the same characteristics as the CAT 5 but features
im roved insulation between the internal airs.
Losses are com ensated using the VIDEO EQ MEDIUM LONG trimmers.
Where MEDIUM and LONG refer to the length of the CAT5 cable.
The MEDIUM trimmer is used to com ensate sections of cable u to half the
maximum length indicated above. For com ensation of longer cable sections,
the MEDIUM trimmer is set to maximum (com letely clockwise) and the LONG
trimmer is adjusted.
To calibrate the system, roceed as follows, se arately for the 2 video signals:
5.1 Using a generator, send a standard video signal, for exam le the bars at
75% or CCIR17 line, to the in ut of the TPA110 T / IRT transmitter unit.

If the section of CAT5 cable exceeds 50% of the maximum section that can be
compensated (see above):
5.3 Tu n the MEDIUM t imme to maximum (completely clockwise).
5.4 Adjust the LONG t imme on the f ont panel of the TPA110 R / IRR eceive
unit until the amplitude of the bu st on the pedestal is between 210 and 300mVpp
5.5 Check that the amplitude of the negative synch onism is between 250 and

For the stereo audio signal, losses due to the cable are not so significant as for
the video signal.
However, for long sections of cable, the output level of the audio signal must be
calibrated in order to compensate for losses due to the cable.
To do this, turn the LEVEL L and R trimmers in a clockwise direction until the
audio signal level reaches that desired.
