M7/M7L/M7LT Modular Satellite Modem Description

M7/M7L/M7LT - Rev. 0.05

Preface

Standard Designations

The M7 designation is used throughout this manual where references apply to either the M7, M7L or

M7LT modems. Where a subject is specific to one modem the “L” or “LT” suffix is used or the specific

differences in operation between the three modem versions are detailed.

Recommended Standard (RS) designations (i.e. RS-232) have been superseded by the new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 M7 Series has been safety tested and shown to comply with standard EN 60950 Safety of

Information Technology Equipment (Including Electrical Business Machines).

The M7 Series is shipped with an external IEC filtered AC to DC power converter module designed to

accept a 3-wire mains connection consisting of an earth ground, neutral and line conductors. The

mating power cord should have a line cord and plug suitable for the country of operation. Installation

and connection to the AC power line must be made in compliance to local or national wiring codes

and regulations.

The external IEC filtered AC to DC power converter module is rated for a nominal operating range of

90 to 264 VAC. The unit has a maximum power consumption of 25 watts.

Never operate the equipment with the cover removed. Never remove the cover with power applied.

As a safety measure the power cord should be disconnected from the unit when preparing to remove

the cover.

Battery

The M7 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 equipment must be operated with the cover and all cover screws in place.

Do not remove the rear panel option plate without replacing it with one designed for a specific

option assembly.

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

assembly. “D” type signal connectors must have grounding fingers on the connector shell.

Description M7/M7L/M7LT Modular Satellite Modem

1-2 M7/M7L/M7LT - Rev. 0.05

Telecommunications Terminal Equipment Directive (TTED)

In accordance with the TTED 91/263/EEC, the M7 Series should not be connected directly to the

Public Telecommunications Network.

RoHS Compliance

The M7 Series satisfies the requirements specified in the European Union Directive on the Restriction

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

Environmental

The M7 Series is designed to operate in an indoor environment. Operation while exposed to

precipitation, condensation, relative humidity above 95%, excessive dust, or temperature outside the

operating range of 0 to +50°C may cause damage to the unit and will void the warranty.

Maximum storage temperature is -20° to +70°C.

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

If the M7 Series is to operation 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 rack installations.

About This Manual

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 M7 Satellite Modem and available options.

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.
