1. DESCRIPTION
1.1. The DVM3001C02
The DVM3001C02 module is a 270Mbit/s SDI video distributor featuring conversion to
analog composite video with 12 bits of resolution. It consists of two sections, each
containing a distributor for digital video with four outputs that provide equalization and
reclocking along with a 4:2:2 PAL/NTSC encoder with two outputs. The DVM3001C02
can also be configured as a single distributor with eight outputs that provide
equalization and reclocking along with a 4:2:2 PAL/NTSC encoder with four outputs.
The DVM3001C02 has been designed for applications where in addition to distribution
of digital video signals a high quality analog video signal is also needed.
Each section of the DVM3001C02 includes a bypass relay on the rear board that
connects the input signal to one of the SD-SDI outputs in case of a power supply failure
or if the main board of the module is removed.
It is possible to monitor the DVM3001C02 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 DVM3001C02 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 DVM3001 family includes several SD-SDI digital video distributors and CCVS
composite video converters, with the following variations:
•DVM3001C01: Dual SD-SDI digital video distributor with one input to four outputs and
two CCVS analog composite video outputs.
•DVM3001C02: Dual SD-SDI digital video distributor with one input to four outputs, two
CCVS analog composite video outputs and one SD-SDI output protected with a bypass
relay on the rear board.

3. INSTALLATION
THE DVM3001C02 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 DVM3001C02 module is composed of two parts: one DVM3001P01 main board and
one XVD3000P05 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 DVM3001P01 main board and one XVD3000P05 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 DVM3001C02
•The DVM3001C02 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 DVM3001C02 modules
as will fit in them.
3.5. Module configuration
The DVM3001C02 module includes a set of microswitches for configuration of various
parameters of the digital-to-analog conversion for the PAL/NTSC encoder. These
microswitches are found in device S1.
-Microswitch 1 allows selection of whether or not the non-visible information
received during the vertical intervals of the digital signal of Section A (test signals,
teletext, etc.) is converted to analog format (VBI PASS YES) or eliminated and these
lines converted to black (VBI PASS NO).
-Microswitch 2 allows selection between two different filters for the luminance of
Section A's PAL/NTSC encoder. The normal filter, (LP FILTER NORM) has a flat response
up to the cutoff frequency, whereas the notch filter (LP FILTER NOTCH) eliminates a
band of frequency centered around the sub-carrier frequency. The luminance
channel bandwidth is 6MHz for both 525 and 625 lines.
- Microswitch 3 has the same functionality as Microswitch 1, but for Section B.
- Microswitch 4 has the same functionality as Microswitch 2, but for Section B.
When the DVM3001C02 is configured as a single distributor with one input, eight digital
outputs and four analog outputs then the input for Section A is distributed to all the
outputs and converted to analog composite video. Also, the configuration of Section A
determines the response of all of the outputs.

3.6. Installing the module in the mounting frame
The steps needed to install the DVM3001C02 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 DVM3001C02 in the mounting frame.
3 - Install the XVD3000P05 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 - Verify that the main board is configured according to the user requirements. The
configuration process is detailed later in the INSTALLATION section of this manual.
6 - Insert the DVM3001P01 board (main board of the DVM3001C02 module) into the
front of the mounting frame. The edges of the card slide into two plastic guides inside

Albalá Ingenieros | Manual DVM3001C02
the mounting frame.
7 - 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.
3.7. Interconnection
The following figure shows the DVM3001C02 module rear board connector layout.
Rear view of the DVM3001C02
The DVM3001C02 module provides two inputs (IN-A,IN-B), four digital video outputs
(OUT0-A to OUT3-A,OUT0-B to OUT3-B) and two analog composite video outputs
(OUT4-A,OUT5-A,OUT4-B,OUT5-B) for each of its two sections. The connectors labeled
OUT0-A/BYPASS-A or OUT0-B/BYPASS-B corresponds to the outputs whose signals are
protected with bypass relays such that if the power supply fails or the module is
extracted signal continuity from the input is maintained.
14

Albalá Ingenieros | Manual DVM3001C02
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.
3.7.1. 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.
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 DVM3001C02. 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.
3.7.2. Analog video connections
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
must be used.

Module remote control and supervision
4.2. Module remote control and supervision
The DVM3001C02 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.

Albalá Ingenieros | Manual DVM3001C02
The following functions of the DVM3001C02 can be performed remotely:
-Configuration of the conversion to composite video (vertical interval blanking, filter
type, removal of chrominance).
- Configuration of the module in single or dual mode.
- Supervision of the presence and status of the input signals.
4.2.1. Details of the DVM3001C02 registers
The DVM3001C02 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 parameters that can be controlled and supervised remotely for each version of
the firmware are listed below:
