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

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 could damage the appliance.

Any operations must be carried 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 W1= ANALOG; W2= LoZ

-IR receiver with TTL output : position W1= TTL; W2= HiZ

The factory setting is as follows:

W1: ANALOG
W2: LoZ

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

178

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.
