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 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

TPA110-IRT/TPA110-IRR TYPICAL SYSTEM

2.0 POWER SUPPLY
The dual TPA110 is powered only via the AC/AC adapter code ADM001 provided.
WARNING
Use of any other adapter ould damage the applian e.
Any operations must be arried out by qualified personnel.
The adapter must be inserted
in a 230 Vac/50Hz outlet.
3.0 SETTINGS
The dual TPA110 T/R has no internal settings.
There are two jumpers inside the dual TPA110 IRT / IRR to adapt use of this to
various IR receivers.
The cover must be removed to set the jumpers. Remove the top four screws to the
sides of each unit.

The jumpers are identified as W1 and W2
W1: TTL : IR receiver with TTL output
ANALOG : IR receiver with analog output
W2: LoZ (Low impedance): : IR receiver with power output
HiZ (High impedance) : IR receiver with high impedance output
The most frequent cases are as follows
-IR receiver with power output : position 1= ANALOG; 2= LoZ
-IR receiver with TTL output : position 1= TTL; 2= HiZ
The factory setting is as follows:
1: ANALOG
2: LoZ

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. )

300mV

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
Fo optimal system functioning the g ound connections
of the sou ces 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 re ote onitoring of the
presence of the inco ing video signal or to indicate an alar if the video signal is
issing.
4.4 connection of AUDIO signals
The stereo audio source ust be connected to the RCA connectors called AUDIO
IN L and R present on the TPA110 T / IRT.
The video destination ust
connected to the RCA connectors
called AUDIO OUT L and R
present on the TPA110 R / IRR.
WARNING
The maximum permitted audio signal is +10dBm.
