1. DESCRIPTION
1.1. The AVD3003C01
The AVD3003C01 module is a triple analog video distributor with loop-through inputs
and two outputs per channel.
The AVD3003C01 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 AVD3003 family includes a variety of video distributors, with the following
variations:
•AVD3003C01: Triple video distributor with loop-through inputs and two outputs per
channel.
•AVD3003C03: Triple video distributor with loop-through inputs, two outputs per
channel and single-adjustment equalizers for various cable types.
1.2. Features
• Triple analog video distributor.
• Includes three identical sections.
• Each section provides one loop-through input and two outputs.
• Wide bandwidth.
•One UR3000 mounting frame can house up to 12 AVD3003C01 modules. If power
supply redundancy is required and FA3000 or FA3001 modules are used then only 10
modules can be housed in the mounting frame. If PSU3300 or PSU3301 modules are
used for this purpose then up to 12 modules can be installed.
• One UR3100 mounting frame can house up to three AVD3003C01 modules.
• Low power.

3. INSTALLATION
THE AVD3003C01 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 AVD3003C01 module is composed of two parts: one AVD3003P01 main board and
one XVD3000P03 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 AVD3003P01 main board and one XVD3000P03 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 AVD3003C01
•The AVD3003C01 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 AVD3003C01 modules as
will fit in them.
3.5. Installing the module in the mounting frame
The steps needed to install the AVD3003C01 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 AVD3003C01 in the mounting frame.
3 - Install the XVD3000P03 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 AVD3003P01 board (main board of the AVD3003C01 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 AVD3003C01 module rear board connector layout.
Rear view of the AVD3003C01
The AVD3003C01 module provides three loop-through inputs (IN-A,LOOP-A,IN-B,
LOOP-B,IN-C,LOOP-C) and two output per section (OUT1-A,OUT2-A,OUT1-B,OUT2-B,
OUT1-C,OUT2-C), all for analog video signals.
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 two BNC connectors configured in loop-through.
The analog video outputs use BNC connectors and have an impedance of 75Ω.
12

Albalá Ingenieros | Manual AVD3003C01
If the loop-through input (LOOP-X) is not used to send signal to another piece of
equipment then it should be terminated with 75Ω.
For analog video connections a coaxial cable with 75Ω of characteristic impedance
must be used.
