1. DESCRIPTION
1.1. The AVP1222C01
The AVP1222C01 is a video preselector that provides twelve loaded inputs and two
outputs. It performs the switching action during the non-visible lines of the vertical
interval using Input 1 as the reference signal. The AVP1222C01 can also be configured to
switch between two fields or between two frames of a television signal.
The AVP1222C01 can operate with PAL or NTSC composite video signals, or three
AVP1222C01 modules can be combined to work with component video. When using
component video the three modules work together as one preselector and the switching
action occurs simultaneously.
The AVP1222C01 can be combined with other modules of the AAPXX2X family installed
in the same mounting frame for simultaneous switching in program material that
contains video and analog audio.
It is possible to monitor the AVP1222C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The AVP1222C01 is a TL3000 terminal line module and can be housed in a three rack
unit (3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame.
The AVPXX2X family consists of four modules within the TL3000 terminal equipment
line, with the following variations:
• AVP0621: A video preselector with six loop-through inputs and one output.
• AVP0622: A video preselector with six loop-through inputs and two outputs.
• AVP1221: A video preselector with twelve loaded inputs and one output.
• AVP1222: A video preselector with twelve loaded inputs and two outputs.

3. INSTALLATION
THE AVP1222C01 MODULE CONTAINS ELECTRONIC DEVICES SENSITIVE TO
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified
with a high degree of shielding for storage and transportation.
The AVP1222C01 module is composed of two parts: one AVP1222P01 main board and
one XVP1222P01 rear board. Both parts must be installed in a UR3000 or UR3100
mounting frame following the instructions in the corresponding section of this chapter.
3.1. Initial inspection
Verify that the package has been properly handled during transport. After opening the
packaging, check that one AVP1222P01 main board and one XVP1222P01 rear board are
inside.
You must notify your Albalá Ingenieros distributor or dealer of any damage or defects
observed.
Follow the instructions in this manual to install this module in the mounting frame.
3.2. Safety instructions
•This equipment must be connected to a mains outlet with a protective
earth connection. Never use extension cords that do not have protective
earthing connection. The lack of an effective electrical connection between
the ground pin in the mains input connector of the equipment and the
protective earth of the electrical power distribution can cause serious harm.
•All modules of the Albalá Ingenieros TL3000 terminal line can be
hot-plugged or unplugged without suffering any damage or affecting the
processes that are currently taking place in other modules in the same
mounting frame. When a module is installed in an empty bay of a mounting
frame, it is necessary to mount the rear board that is part of that module.
Prior to installing this board, the mounting frame must be disconnected
from the power supply network. This is required because in addition to the
risk of electrocution for the person handling the device it is possible that a
high instantaneous current coming from the power supply could damage
the connectors and components of the mounting frame and/or the rear
board.

Albalá Ingenieros | Manual AVP1222C01
•The AVP1222C01 module and the mounting frame should always be
installed, maintained, operated and removed by personnel with sufficient
technical qualifications. The equipment should never be placed in damp
areas, near splashing liquid, or in explosive or corrosive atmospheres.
Neither modules nor mounting frames can be used in applications that
could endanger human life.
3.3. Environmental considerations
This symbol indicates that this equipment must be deposited at a collection
point for proper waste treatment once it has reached the end of its useful
life.
3.4. Power considerations
The UR3000 and UR3100 mounting frames can house as many AVP1222C01 modules as
will fit in them.
3.5. Installing the module in the mounting frame
The steps needed to install the AVP1222C01 module with the rear board in the
mounting frame are:
1 - Disconnect all power cords from the power supplies of the mounting frame.
2 - Remove the blank panels covering the front and rear of the empty bays chosen for
installing the AVP1222C01 in the mounting frame.
3 - Install the XVP1222P01 rear board ensuring that its 12-pin connectors are properly
aligned with the mounting frame´s mating connectors. Check that the orientation of
the board is correct by looking at the placement of the text printed on it according to
the illustration below.
4 - Attach the rear board to the mounting frame with two M3 metric screws and tighten.
5 - Insert the AVP1222P01 board (main board of the AVP1222C01 module) into the front
of the mounting frame. The edges of the card slide into two plastic guides inside the
mounting frame.
6 - Affix the main board to the mounting frame using the two screws included on the
front panel.
After these steps, the module is ready to be connected to other equipment.

The AVP1222C01 module has twelve inputs (IN1 to IN12) and two analog video outputs
(OUT1 and OUT2).
The rear interconnection board is not designed to withstand mechanical stress. The
wiring must be fastened properly to the frame where the mounting frame is housed to
prevent the rear board from supporting the weight of the cables.
3.6.1. Analog video connections
The analog video inputs use BNC connectors with an impedance of 75Ω.
The analog video outputs use BNC connectors and have an impedance of 75Ω.
For analog video connections a coaxial cable with 75Ω of characteristic impedance

4.2. Functional description
Selection of the active input to the preselector is done remotely, either by a PC or with a
control keypad. The following section will explain the various ways to connect the
preselector to PC or control keypad.
The AVP1222C01 has two different switching modes, depending upon how it will be
used.
When only one preselector module is being used then the AVP1222C01 operates in
Master Mode. In Master Mode the AVP1222C01 only responds to commands received
from the internal communications bus of the mounting frame directed to the slot where
the preselector is installed.
In systems that use multiple preselectors that must all switch at the same time, for
example when switching component video, the module can be operated in Slave Mode,
in which it responds to commands sent to a module in Master Mode installed in a
different slot. In Slave Mode the module continues to respond to commands sent to the
slot where it is installed.
The switching action between the different inputs can be performed with four different
switching times, depending upon the configuration of the preselector and the presence
or absence of a vertical sync signal.
-When the switching time is set to FAST the preselector will switch as soon as it
receives a command to do so. Switching also takes place immediately, even when
commanded to do so at a different time if no vertical sync signal is present.
-When the switching time is set to FIELD and a signal is present at Input 1 the
preselector will switch during the first vertical interval produced after receiving the
switching command.
-When the switching time is set to FRAME and a signal is present at Input 1 the
preselector will switch during the first vertical interval between Field Two and Field
One produced after receiving the switching command.
-Finally, if the switching time is set to SLAVE then the preselector will switch at the
same instant that the module installed directly to the right switches.
The following section will explain the two most common configurations of the
AVP1222C01 for switching during the vertical interval for both composite video and
component video.

Module remote control and supervision
4.3. Module remote control and supervision
The AVP1222C01 requires remote control for configuration.
In order to perform remote configuration and supervision of the module an optional
TL3000 family remote communications controller must be installed in the mounting
frame.
The main function of the communications control module is to interface between a
10/100 Ethernet port, an EIA-RS232 or an EIA-RS485 serial port and the internal bus of
the mounting frame. The following illustration shows the most common control
situations: from a computer or control panel via Ethernet, from a computer via an
EIA-RS232 serial port and from a control panel via an EIA-RS485 serial port.
Certain communications control modules provide additional, more advanced functions
such as an SNMP agent, logging of status changes of the modules and a Web interface
for remote control, etc.
Software for simple configuration and supervision with a GUI for multiple modules can
be downloaded from the Albalá Ingenieros website.
