Preface

About This Manual

This manual describes the features of a speciﬁc 2000 Series module in the

Kameleon Media Processing System. 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 Series Frames

Instruction Manual).

2041EDA Instruction Manual 7

2041EDA Wideband Rear

Equalizing Distribution

AmpliÞer

Introduction

The 2041EDA Wideband Rear Equalizing DA provides basic equalization

and distribution of a single standard or high deﬁnition wideband signal

(4 Mb/s to 1.5 Gb/s) to eight outputs. The single module resides in any

rear slot of a Kameleon 2000 Series frame and is independent of any front

card for operation.

The features of the 2041EDA include:

•Auto equalization of both SD and HD signals,

•Accepts a wide range of standard or high deﬁnition input signal stan-

dards,

•Use of non-inverted outputs allow distribution of compressed signals

such as SMPTE 310M and DVB-ASI,

• Ideal for monitoring or distributing reclocked signals from adjacent

2000 modules, and

•Remote control and monitoring support.

82041EDA Instruction Manual

Installation

Installation of the 2041EDA module is a process of:

• Placing the module in a rear frame slot, and

•Cabling signal ports.

The 2041EDA module can be plugged in and removed from a Kameleon

2000 Series frame with power on. When power is applied to the module,

LED indicators reﬂect the initialization process (see

Power Up

on page 10).

Module Placement in the 2000 Frame

There are twelve rear cell locations in the 3 RU frame to accommodate

either analog or digital modules. The 2041EDA rear module plugs into any

one of the rear slots of the Kameleon 2000 frame.

Install the module by inserting it into any rear slot of the frame as

illustrated in Figure 1.

Verify that the module connector seats properly against the midplane.

Secure the module to the rear of the frame with the two screw locks on

either side of the back panel using a crossblade screwdriver.

Installation

Cabling

Cabling to the 2041EDA module is done on the BNCs on the rear of the

module. Refer to Figure 2 for a detailed illustration of the rear connections

referenced below.

Inputs

The 2041EDA will accept any of the video standards listed in the Input

speciﬁcations in Table 3 on page 14. Connect a video input to BNC J10.

Outputs

The 2041EDA outputs conform to the video standards listed in the Output

speciﬁcations in Table 3 on page 14.

Connect video destinations to any of the eight outputs at connectors J2 – J9.

Terminate any unused outputs.

Note

BNC J1 is not used on this module. On earlier versions of the 2041EDA

labeled with part number 671-5248-00, BNC J1 provided an output.

Power Up

The on-board LED indicators are illustrated in Figure 3. Upon power-up,

the green PWR LED should light and the yellow CONF LED should illumi-

nate for the duration of module initialization.

Operation Indicator LEDs

With a valid input signal connected, the green on-board PWR LED,

SIG_PRES LED and the SIG LED (visible from the rear) should be on. Refer

to Table 1 on page 11 to see a complete list of possible operating conditions

and the resulting indicator status.
