1. DESCRIPTION
1.1. The DVM3001C02
The DVM3001C02 module is a 270Mbit/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.

1.2. Features
• Dual SD-SDI digital video distributor with composite video encoder.
• Provides two sections, each equipped with:
- A one input to four output SD-SDI video distributor.
- A PAL/NTSC composite video encoder with two outputs.
•Can be configured to distribute one input to eight outputs with four PAL/NTSC video
outputs.
•Each section provides a bypass relay on the rear board that enables the input signal to
be passed through to one of the SD-SDI outputs in case of power loss or module
removal.
•Provides automatic equalizers at the inputs capable of compensating 300+ meters of
Belden 8281 cable.
• Includes reclocking.
• Automatic detection of input signal format (525/625 lines).
• Front panel indicators for signal presence and maximum equalization.
• Provides presets for module configuration storage.
•Module control and supervision can be done remotely when the mounting frame is
equipped with a communications controller module.
•One UR3000 mounting frame can house up to 12 DVM3001C02 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 DVM3001C02 modules.
• Low power.
