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.

2042EDA Instruction Manual 1

2042EDA Dual Wideband Equalizing Distribution Amplifier

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).

Cabling

Inputs

Outputs

Cabling to the 2042EDA module is done on the BNCs on the passive rear
module. Refer to Figure 5 for a detailed illustration of the rear connections
referenced below.

The 2042EDA will accept any of the video standards listed in the Input
specifications in Table 3 on page 10. Connect a video input to In 1, BNC J10
and In 2, BNC J5.

The 2042EDA outputs conform to the video standards listed in the Output
specifications in Table 3 on page 10.

Installation

Connect video destinations to the four outputs for In 1 at Out 1A – Out 1D
(BNCs J9 – J6 respectively) and the four outputs for In 2 at Out 2A– Out 2D
(BNCs J4 – J1 respectively). Terminate any unused outputs.

Service

The 2042EDA modules make extensive use of surface-mount technology
and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be ser­viced in the field unless otherwise directed by Customer Service.

Power-up Diagnostics Failure

If the module has not passed self-diagnostics, do not attempt to trouble­shoot. Return the unit to Grass Valley (see

Troubleshooting

Module Repair

).

If your module is not operating correctly, proceed as follows:

■

Check frame and module power. If power is not present, check the fuse
on the +24V input to the module as illustrated in Figure 10.

Check for presence and quality of input signals.

■

■

Verify that source equipment is operating correctly.

■

Check cable connections.

Input Processing

The two wideband channels for serial SD or HD signals enter the module
from rear BNCs J10 (In 1) and J5 (In 2) on the passive rear module to input
amplifiers. The signals are then equalized for specified cable lengths in the
equalizer circuit.

Microprocessor

2042EDA Instruction Manual 13

The main functions of the microprocessor include:

■

■

■

Providing remote control and monitoring capability for the module
(through ethernet),

Communicating with equalizer ICs to monitor signal present status,
and

Relaying module status through on-board LEDs.

2042EDA Dual Wideband Equalizing Distribution Amplifier

Output Processing

Driver circuits feed each of the four serial digital outputs for each input to
the rear BNCs J6 – J9 (Out 1A – Out 1D) and J1 – J4 (Out 2A – Out 2D) on
the passive rear module. These outputs are non-inverting and are in-phase
with each other.

Power Supply

Power is fed from +24 V rails of the frame’s switching power supply. The
power input is protected by a socketed fuse (Figure 10). Each amplifier
circuit on the module receives its own, separate, highly regulated and fil­tered power source to reduce EMI and on-board crosstalk.
