About This Manual

This manual describes the features of a specific module of the 2000 Series
Modular Products family. As part of this module family, it is subject to
Safety and Regulatory Compliance described in the 2000 Series frame and
power supply documentation (see the

2000 Frames Instruction Manual

).

2042EDA Dual Wideband
Equalizing Distribution
Amplifier

Introduction

The 2042EDA Dual Wideband Equalizing DA provides two wideband
channels for equalization and distribution of standard or high definition
input signals (4 Mb/s to 1.5 Gb/s) to four outputs each. The module set
includes a media module that resides in the front of a 2000 Series frame and
a passive rear module for input and output connections.

The features of the 2042EDA include:

■

Auto equalization of standard and high definition signals,

■

Accepts a wide range of standard or high definition input signal stan­dards,

■

Use of non-inverted outputs allow distribution of compressed signals
such as SMPTE 310M and DVB-ASI, and

■

Remote monitoring support.

Installation

Installation of the 2042EDA module set is a process of:

Placing the passive rear module in a frame slot,

■

■

Placing the media module in the corresponding front slot, and

■

Cabling and terminating signal ports.

The 2042EDA module can be plugged in and removed from a 2000 Series

frame with power on. When power is applied to the module, LED indica-

tors reflect the initialization process (see Power Up on page 6).

Module Placement in the 2000 Frame

There are twelve slot locations in both the front and rear of a 3RU frame to

accommodate 2000 Series modules. The 2042EDA consists of a two module

set with a front media module and a passive rear module that can be

plugged into any of the 12 frame slots. Each 2042EDA front media module

plugs into the front of the 2000 frame mid-plane. The passive rear module

plugs into the corresponding rear slot to provide the input and output

interface connectors.

Mid-frame motherboard

with power and

communication buses

To install a 2042EDA module set in the frame:

1.

Locate a vacant slot in the rear of the 3 RU frame (Figure 1).
