1 Introduction

This document is the user manual provided with the sat-nms LSM switch matrix. It contains all necessary information how to install, setup, and operate the unit. The user manual is available as a printed document and for on-line reading on the switch matrix itself as well.

A Switch Matrix fits in the multimedia ground terminal as a central unit which collects at its input the receive signals from all the antennas with their Low Noise Block Converters (LNC) and distribute these signals without any blocking at numerous outputs. The switch matrix allows the user to switch each input to each output without any blocking effects. This gives the user of a switch matrix an unlimited routing and configuration capability. He can configure its total receive system in numerous ways depending to its requirements on demand. This is especially necessary for occasional use and for monitoring purposes.

The focus during the development was on excellent RF performance and operational stability. So everything is hot-swap. The sat-nms LSM switch matrices are designed in a modular form and are easy to expand to any size .

The paragraphs below give a short overview to the contents of the documentation. A subset of this documentation is stored on the device itself, the complete documentation is available on the sat-nms documentation CD and at www.satnms.com.

• Installation : The installation chapter guides through the installation and setup of the sat-nms LSM. It describes the mechanical concept of the LSM chassis and the assignment of the connectors. Finally you learn in this chapter how to set the LSM's IP address, which is a essential precondition to operate the LSM by means of a web browser. This section is available in the printed version only.
• Operation : The sat-nms LSM is operated using a standard web browser like the Internet-Explorer or Mozilla Firefox. The user interface design is straight forward and clearly structured. Operating the LSM is mostly self-explanatory. Nevertheless, the 'Operation' chapter outlines the map of web pages which make up the LSM user interface and elaborately describes the meaning of each alterable parameter.
• Remote Control : The sat-nms LSM provides a versatile remote control interface. A monitoring & control software may fully operate the LSM either through a TCP/IP network connection or through the RS232 interface of the LSM. This chapter describes the communication protocol used for remote control and lists all parameters accessible through the remote interface.
• Theory of Operation : This chapter gives a short overview how the matrix and the different modules works together.
• Specifications : At the end of the document, the specifications applicable to the sat-nms LSM are summarized in this chapter.
