Preface

This manual is intended for use by personnel with reasonable knowledge of satellite

communications and earth station terminology. This manual provides Installation,

Operating, and Maintenance procedures for the M7XC Compact Satellite Modem and

available options.

Standard Designations

The M7XC designation is used throughout this manual where references apply to the

M7XC Compact Satellite Modem. The designation for the M7XC may also be referred

to as ‘modem’ or ‘unit’ interchangeably.

Recommended Standard (RS) designations (i.e., RS-232) have been superseded by

the new designation of the Electronic Industries Association (EIA) designations (i.e.,

EIA-232). The RS and EIA designation may be used interchangeably within the

manual and protocol documentation and have the same electrical and mechanical

meaning.

Electrical Safety and Compliance Notice

The M7XC has been safety tested and shown to comply with standard EN 60950

Safety of Information Technology Equipment (Including Electrical Business

Machines).

Never operate the unit with the cover removed. Never remove a cover with power

applied. As a safety measure the power cord must be disconnected from the unit when

preparing to remove the cover.

Battery

The M7XC optionally contains a Lithium Battery. Danger of explosion exists if the

battery is incorrectly replaced. Replace only with the same or equivalent type

recommended by the manufacturer. Dispose of used batteries in accordance with

local and national regulations.

EMC (Electromagnetic Compatibility) and Safety Compliance

This equipment has been tested in accordance with FCC and ESTI standards.

 FCC: Part 15, Subpart B, Class A

 ETSI EN 301 489-1 V1.9.2 (2011-09) (Emissions and Immunity)

 EN 55022 (2010) (Emissions)

 EN 55024 (2010) (Immunity)

 EN 60950-1:2006 (2nd Edition) and IEC 60950-1:2005 (Safety)

To maintain compliance with these standards the following the precautions must be

observed.

 The unit must be operated with the cover attached with all cover screws in

place.

M7XC Compact Satellite Modem Specification

v0.02 vii

 All connections are designed to have integral shielding on the cable and

connector assembly.

Telecommunications Terminal Equipment Directive (TTED)

In accordance with the TTED 91/263/EEC, the M7XC should not be connected directly

to the Public Telecommunications Network.

RoHS Compliance

The M7XC satisfies the requirements specified in the European Union Directive on

the Restriction of Hazardous Substances, Directive 2002/95/EC (EU RoHS).

Environmental

The M7XC is designed to operate in an enclosed environment. Operation while

exposed to precipitation, condensation, relative humidity above 95%, excessive dust,

or temperature outside the operating range of -40o C to +60° C temperature range

may cause damage to the unit and will void the warranty. Maximum storage

temperature is -55° C to +70° C.

Do not operate the modem in an unsafe environment near explosive or flammable

gases or liquids.

If the M7XC is to operate in a mobile environment, the user must take precautions to

provide a stable environment consistent with the equipment specifications.

Grounding

Insure good grounding practices. Where a ground lug is provided, the modem should

be connected to a good earth ground with low impedance cable in installations.

About This Manual

This manual is composed of several separable documents. The main body of the

manual is separated into several “Chapters” and “Sections”. The Chapters within the

main manual are the Modem Description, Installation, Operation, and Maintenance.

The Appendices include the Specifications, Remote Control Protocol and information

on Options, Cabling and information related to placing the Modem in service.

A Section is considered a sub-section of a Chapter. For example, Section 4.1.2 is a

numbered section within Chapter 4. Page numbers include the Chapter (i.e., Page 3-

14) and all Tables and Figures will show the Chapter in the caption (i.e., Table 1-2).

This manual is available in a printed form and as an electronic “Portable Document

Format” or .PDF file. The electronic format is produced as a universal Adobe Acrobat

readable file, and can be requested directly from Datum Systems, Inc., or via

download from the web at www.datumsystems.com. The electronic format on the web

is always the latest revision.

M7XC Compact Satellite Modem Introduction

v0.02 1-1

1 Introduction

Modem Description

The M7XC, represented in Figure 1-1, is a major extension of our innovative design

concepts that have been proven and refined in over twenty years of production.

The M7XC is capable of independent transmission and reception of carriers

compliant to most satellite communications standards. The M7XC uses the latest

Digital Signal Processing (DSP) technology and other proprietary techniques to

provide unsurpassed performance. The M7XC is a highly modular design made

possible by a higher level of integration.

Figure 1-1 - Compact Satellite Modem

The dimensions of the black enclosed M7XC with fan and heatsink are 5” (L) x 3”

(W) x 1.3” (H) and weighs < 2 lbs.

The dimensions of the silver enclosed M7XC without fan and heatsink are 5” (L) x

3” (W) x 1.0” (H) and weighs < 2 lbs.

The M7XC is end-to-end compatible with all Datum Systems M7 series modems.

The M7XC is designed to be integrated into a compact satellite terminal for use in

a variety of satellite systems. The satellite terminals may be small fly-away

systems, Manpack, Airborne/UAV, or other mobile satellite terminal applications.

The M7XC design can also be integrated with other M7XC units into a master hub

station.

Figure 1-2 - Compact Hub Modems

The highly integrated design allows system designers the flexibility to integrate

units into many different innovative hardware system designs. The M7XC is an

Introduction M7XC Compact Satellite Modem

integral part of a satellite earth station’s equipment operating between the Data

Terminal Equipment and the station RF equipment.

The M7XC is designed for operation in different network types. Operating modes

may be dedicated or shared. In a dedicated system two modems are set for

continuous operation with each other. In shared systems, the modem carriers are

typically controlled by a Network Management System (NMS).

Network Types

The M7XC is extremely flexible regarding the network types that can be

configured. Depending on the network type, different baseband interface options

are available that will maximize the capability for the network. The main network

types are:

 Point-to-Point

 Point-to-Multipoint

 Mesh

 Hybrid

In a Point-to-Point (P2P) network, the M7XC provides the industry leading Eb/No

performance and flexible baseband interface options. This performance

improvement and the Ethernet/IP interface in the M7XC provide the network

operator with the latest technology needed to extend cellular backhaul connectivity

and Internet access to remote locations. With Ethernet bridging capabilities

internal to the M7XC, there is a significant reduction in the number of devices that

need to be managed and maintained. A typical P2P network is shown in Figure

1-3.
