Introduction

RX8200 Configuration Guide 5

1 INTRODUCTION

The RX8200 Receiver is a component of the MPEG-4 AVC/ MPEG-2/DVB compliant range of Ericsson equipment

designed for use by broadcasters and distributors of video, audio and data services over satellite.

Figure 1 RX8200 Satellite Receiver

The Satellite Receiver interfaces directly to a Low-Noise Block (LNB) on a satellite dish and takes an intermediate

frequency (IF) input in the band 950 - 2150 MHz (L-band). The unit can provide dc power and polarisation

switching to the LNB.

The receiver can be tuned to a Reuters satellite channel frequency and polarisation. The input is down-converted

via an LNB to provide an L-band input to the Receiver. The received Reuters satellite channel contains two

services within the Receiver’s demultiplexer. These are configured to select a single video Service (Reuters Live

Service) and other audio/data (World News Express) components and present them at the receiver output(s).

In short, this receiver processes both RLS and WNE content for Reuters Broadcasting clients.

1.1 FRONT PANEL CONTROLS

The physical interface for the Front Panel consists of an alphanumeric LCD display, pushbuttons, and a status LED

that can used to set-up and monitor the unit. User input is via six pushbuttons comprising of four cursor

pushbuttons: Left, Right, Up, and Down; and two edit control pushbuttons: EDIT and SAVE.

Each pushbutton has an integral green LED except SAVE, which has an integral red LED. When lit, these LEDs

indicate to the User which pushbutton is currently active.

1.2 FRONT PANEL LEDS

Receiver status as follows:

A red status LED is used to indicate an RX8200 Receiver fault condition, for example, a missing or faulty input

signal. It should be off for correct operation, although it may be lit briefly during power up.

An orange status LED is used to indicate that the RX8000 Receiver is locked to a Transport Stream, but also

indicates incorrect conditions or incorrect system functioning.

A green status LED is used to indicate that the RX8000 Receiver is locked to a Transport Stream and also

indicates correct conditions and correct system functioning.
