1. DESCRIPTION
1.1. The PDC3002C01 The PDC3002C01 module is a PAL/NTSC analog composite video to 270Mbit/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 75Ω of characteristic impedance must be used.
3.6.3. GPIO connections The GPIOs use 3.81mm 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.

Albalá Ingenieros | Manual PDC3002C01
In the CHANNEL A and CHANNEL B boxes:
18
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.
Albalá Ingenieros | Manual PDC3002C01
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.

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:

5. GLOSSARY
EDH Error Detection and Handling. A system for detection of errors in SD-SDI signal transmission. It consists of the insertion of a CRC (Cyclic Redundancy Check) packet at the end of each video field to check the data in that field. The receiving equipment calculates the CRC for the data received and compares it with the CRC received in the packet to determine if errors are present in the transmission.
GPIO General Purpose Input/Output. General purpose signaling interface that can operate as an input (GPI) or output (GPO).
SD-SDI Standard Definition - Serial Digital Interface. A serial digital interface capable of transmitting standard definition television signals with bitrates of 143Mbit/s, 177Mbit/s, 270Mbit/s or 360Mbit/s.
SDI Serial Digital Interface. A standard used for the transmission of uncompressed video signals that can also include audio and time code signals.
