handbook
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 TPA110 IRT or TPA110 IRR;
-an IR emitter which will be connected to the IR OUT jack of the TPA110 IRR or
TPA110 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, there are usually 2 independent video sources to be
directed towards two destinations. A CAT5 cable is used for transmission between
the transmission and receiving units. The CAT5 cable is the standard cable used
for local computer networks and consists of four unshielded twisted pairs (UTP).
The maximum lengths of the CAT5 cable that can be compensated are:
-375mt. for cable type AWG26
-500mt. for cable type AWG24
-650mt. for cable type AWG22
For monitoring and signal present type applications, sections of up to 900mt of
AWG22 CAT5 cable can be used.
In critical noise conditions, in order it improve the all-round performance of the
system, the CAT6 cable can be used.
WARNING
Pay particular attention to grounding
of the sources and destinations (see par. 4.2)

5.2 Go to the TPA110 R/IRR receiver unit and connect a waveform monitor or an
oscilloscope that can be synchronized on the horizontal synchronism (H) to the output
video signal, making sure that the input of the instrument is terminated at 75Ω.
If the section of CAT5 cable is equal to or less than 50% of the maximum section
that can be compensated (see above):
5.3 Set the LONG trimmer to zero (fully counterclockwise)
5.4 Adjust the MEDIUM trimmer on the front panel of the TPA110 R / IRR receiver
unit until the amplitude of the burst on the pedestal is between 210 and 300mVpp
(If necessary, adjust the LONG trimmer turning this a few degrees in a clockwise
direction).
5.5 Check that the amplitude of the negative synchronism is between 250 and
300mV

The video destination must be connected to the BNC VIDEO OUT connector of
the TPA110 R / IRR receiving unit.

WARNING
For optimal system functioning the ground connections
of the sources and of the destinations
must be as equipotential as possible.
Different ground potentials may cause faults.

4.3 Connection of the VIDEO dry contact
The VIDEO dry contact belongs to a relay that is energized when a correct video
signal is received. This contact can be used for remote monitoring of the
presence of the incoming video signal or to indicate an alarm if the video signal is
missing.
4.4 connection of AUDIO signals
The stereo audio source must be connected to the RCA connectors called AUDIO
IN L and R present on the TPA110 T / IRT.

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 be 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, Kenwood, Pioneer) use remote controls with carrier frequencies of up to
1,125MHz.
WARNING
Make sure that you buy an IR receiver
that is compatible with the frequency of the remote control.
The TPA110 IRT / IRR are compatible with
frequencies of up to 1.2MHz

The IR receivers available on the market are of the 3-wire type: Positive (+), GND
(0 Volt) and SIGNAL.
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 SIGNAL 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 SIGNAL 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
can be recommended as they consume less and 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 components
of the video signal. As the composite video signal is a complex signal that does
not accept downgrading, for each installation calibration must be performed in
order to offset cable losses. The unit that makes this compensation is the
receiving unit, in our case the TPA110 R / IRR.
WARNING
The TP110R / IRR unit is precompensated for 50 mt of CAT5 cable
However, 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 compensated are:
-375mt. for cable type AWG26
-500mt. for cable type AWG24
-650mt. for cable type AWG22
For monitoring and signal present type applications, sections of up to 900mt of
AWG22 CAT5 cable can be used.
In critical noise conditions, in order it improve the all-round performance of the
system, the CAT6 cable can be used.
The CAT6 cable has the same characteristics as the CAT 5 but features
improved insulation between the internal pairs.
Losses are compensated 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 compensate sections of cable up to half the
maximum length indicated above. For compensation of longer cable sections,
the MEDIUM trimmer is set to maximum (completely clockwise) and the LONG
trimmer is adjusted.
To calibrate the system, proceed as follows, separately for the 2 video signals:
5.1 Using a generator, send a standard video signal, for example the bars at
75% or CCIR17 line, to the input of the TPA110 T / IRT transmitter unit.

916

If the section of CAT5 cable exceeds 50% of the maximum section that can be
compensated (see above):
5.3 Turn the MEDIUM trimmer to maximum (completely clockwise).
5.4 Adjust the LONG trimmer on the front panel of the TPA110 R / IRR receiver
unit until the amplitude of the burst on the pedestal is between 210 and 300mVpp
5.5 Check that the amplitude of the negative synchronism is between 250 and
300mV
WARNING
The trimmers are factory set for minimum
compensation (counterclockwise)
of 50 mt. of AWG26 CAT5 cable.
If you have purchased the dual TPA110 IRT / IRR, arrival of a correct video
signal is indicated by lighting up of the green led located between the two
adjustment trimmers. if the green led is off, this means that there is no correct
video signal on the output.

For other information regarding connection, refer to paragraph 4.3
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.
