1. DESCRIPTION
1.1. The PDC3002C01
The PDC3002C01 module is a PAL/NTSC analog composite video to 270Mbit/s SDI
digital video converter. The PDC3002C01 has been designed for application where high
quality conversion of analog video to digital video is needed.
The PDC3002C01 consists of two independent sections, each of which has one analog
video input with loop-through and two digital video outputs. Each section also provides
two GPIOs.
The PDC3002C01 uses a high quality VCTCXO for the video conversions that guarantees
a jitter of less than 0.2 U.I. In the SDI output signal.
The PDC3002C01 is capable of inserting EDH packets as well as decoding the VPS
information received in the signal. It can also generate digital black with its oscillator in
free-running mode when no valid signal is present at the input.
It is possible to monitor the PDC3002C01 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 PDC3002C01 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.

3. INSTALLATION
THE PDC3002C01 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 PDC3002C01 module is composed of two parts: one PDC3002P01 main board and
one PDC3002P02 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 PDC3002P01 main board and one PDC3002P02 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.
11

Albalá Ingenieros | Manual PDC3002C01
•The PDC3002C01 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 PDC3002C01 modules as
will fit in them.
3.5. Installing the module in the mounting frame
The steps needed to install the PDC3002C01 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 PDC3002C01 in the mounting frame.
3 - Install the PDC3002P02 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 PDC3002P01 board (main board of the PDC3002C01 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.

3.6. Interconnection
The following figure shows the PDC3002C01 module rear board connector layout.
Rear view of the PDC3002C01
The PDC3002C01 module provides one analog video input with loop-through per section
(CCVS-INA/CCVS-LOOPA and CCVS-INB/CCVS-LOOPB) and two digital video outputs per
section (SDI-OUT1A,SDI-OUT2A and SDI-OUT1B,SDI-OUT2B). It also provides two GPIOs
per section (GPIO1A/GPIO2A and GPIO1B/GPIO2B).
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. Electrical SDI video connections
All electrical SDI video connections are BNC type. The following suggestions should be
kept in mind when wiring the electrical signals.
14

Albalá Ingenieros | Manual PDC3002C01
BNC connectors used on cables must be suitable for the high frequencies of digital
video signals: it is strongly recommended to use high quality connectors from well
known manufacturers.
All coaxial cable used must be Belden 8281 or similar. This type provides the greatest
lengths because it is used to calculate the equalizers in the PDC3002C01. Cables
carrying signal between the module and the devices should use single piece
construction, avoiding spliced sections with double BNC female or barrel connectors.
If it is necessary to split the cable into two sections the same type of wire should be
used in both sections.
The use of analog video coaxial cables RG-59 type or similar is not recommended for
digital video except for very short distances.
3.6.2. Analog video connections
The analog video inputs use two BNC connectors configured in loop-through.
For analog video connections a coaxial cable with 75Ω of characteristic impedance
must be used.
3.6.3. GPIO connections
The GPIOs use 3.81mm pitch terminal block connectors and have the following
equivalent circuit:
Consult the maximum values listed in the specifications section of this manual before
making any connections to the GPIOs. Never connect hazardous voltages to the GPIO
inputs.
15

Albalá Ingenieros | Manual PDC3002C01
Each section contains two GPIOs: GPIO1A and GPIO2A in Section A; and GPIO1B and
GPIO2B in Section B. The polarity of the GPIOs is configurable using a register in the
EEPROM. With normal polarity, a GPIO is active when short-circuited to ground and
inactive when it is open-circuit. The polarity configuration is the same for both
sections.
There are two operating modes for the GPIOs. Each section can be configured
independently. The modes are:
• Mode 1:
-GPIO1x: When activated this input forces the outputs of the corresponding section
to digital black.
-GPIO2x: This output activates when an error occurs in the corresponding section.
• Mode 2:
-GPIO1x: This output reflects the value of bit 0 of the VPS received at the input.
-GPIO2x: This output reflects the value of bit 1 of the VPS received at the input.

4. OPERATION
This section describes the significance of the front panel indicators of the PDC3002C01
module and their remote control and monitoring ability.
4.1. Front panel description
The appearance of the front panel and the elements it contains are shown in the
following illustration.
Front panel of the PDC3002C01
The panel contains the following elements:
17

Albalá Ingenieros | Manual PDC3002C01
In the CHANNEL A and CHANNEL B boxes:
INPUT FAIL: Red. These LEDs light up when no valid signal is present at their
corresponding inputs.
They blink when the oscillator is incapable of locking to the signal being
received. The two most common causes of this are an input signal with
excessive frequency deviation or with excessive jitter.
SIG. PRES.: Green. These LEDs light up when the signal at their corresponding
outputs is a digital version of the signal received at the input.
They blink when digital black (generated by the module) is being sent to
the outputs.

Module remote control and supervision
4.2. Module remote control and supervision
The PDC3002C01 can optionally be remotely controlled/supervised.
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.
19

Albalá Ingenieros | Manual PDC3002C01
The following functions of the PDC3002C01 can be performed remotely:
- Configuration of the conversion operation.
- Supervision of the status of the input signals.
4.2.1. Details of the PDC3002C01 registers
The PDC3002C01 module provides control and status registers that can be read and
written by means of specific commands described in the communication control
module user manuals.
The parameter information grouped in the CONTROL or RAM sections is stored in
volatile memory. Any modifications to the parameters will be lost when the module
power supply is disconnected unless the "EEPROM Save" button within the software
has been pressed.
The STATUS section parameters are read-only and cannot be modified.
The EEPROM section parameters are rarely used and are stored directly in non-volatile
memory.
The parameters that can be controlled and supervised remotely for each version of
the firmware are listed below:
