Preface MN/DST.IOM
ELECTRICAL SAFETY
The DST Digital Satellite Terminal System has been shown to comply with the following safety
standard:
• EN 60950: Safety of Information Technology Equipment, including electrical business
machines.
The equipment is rated for operation over the range 85 to 264 volts AC. It has a maximum
power consumption of 60 watts.
FUSES
The DST is fitted with two fuses, one each for line and neutral connections. These are contained
within the body of the IEC power connector, behind a small plastic flap.
For continued operator safety, always replace the fuses with the
IMPORTANT
correct type and rating. Refer to the SDM /CiM manual.
Environmental
The DST must not be operated in an environment where the unit is exposed to extremes
of temperature outside the ambient range 0 to 50°C (32 to 122°F), precipitation,
condensation, or humid atmospheres above 95% RH, altitudes (un-pressurised) greater
than 2000 metres, excessive dust or vibration, flammable gases, corrosive or explosive
atmospheres.
Operation in vehicles or other transportable installations that are equipped to provide a
stable environment is permitted. If such vehicles do not provide a stable environment,
safety of the equipment to EN60950 may not be guaranteed.
ix
Digital Satellite Terminal System Revision 2
Preface MN/DST.IOM
Installation
The installation and connection to the line supply must be made in compliance to local or
national wiring codes and regulations.
The DST is designed for connection to a power system that has separate ground, line and
neutral conductors. The equipment is not designed for connection to power system that
has no direct connection to ground.
The DST is shipped with a line inlet cable suitable for use in the country of operation. If
it is necessary to replace this cable, ensure the replacement has an equivalent
specification. Examples of acceptable ratings for the cable include HAR, BASEC and
HOXXX-X. Examples of acceptable connector ratings include VDE, NF-USE, UL, CSA,
OVE, CEBEC, NEMKO, DEMKO, BS1636A, BSI, SETI, IMQ, KEMA-KEUR and
SEV.

EMC (Electromagnetic Compatibility)
In accordance with European Directive 89/336/EEC, the DST has been shown, by
independent testing, to comply with the following standards:
Emissions: EN 55022 Class B - Limits and methods of measurement of radio interference
characteristics of Information Technology Equipment.
(Also tested to FCC Part 15 Class B)
Immunity: EN 50082 Part 1 - Generic immunity standard, Part 1: Domestic, commercial
and light industrial environment.
Additionally, the DST has been shown to comply with the following standards:
EN 61000-3-2 Harmonic Currents Emission
EN 61000-3-3 Voltage Fluctuations and Flicker
EN 61000-4-2 ESD Immunity
EN 61000-4-4 EFT Burst Immunity

EN 61000-4-9 Pulse Magnetic Field Immunity
EN 61000-4-11 Voltage Dips, Interruptions, and Variations Immunity
EN 61000-4-13 Immunity to Harmonics
In order that the Modem continues to comply with these standards,
observe the following instructions:
IMPORTANT
xi
Digital Satellite Terminal System Revision 2
Preface MN/DST.IOM
• Connections to the transmit and receive IF ports (Type N and Type F, female,
connectors) should be made using a good quality coaxial cable - for example
RG58/U (50Ω) or RG59/U (75Ω).
• All 'D' type connectors attached to the rear panel must have back-shells that
provide continuous metallic shielding. Cable with a continuous outer shield
(either foil or braid, or both) must be used, and the shield must be bonded to the
back-shell.
• The equipment must be operated with its cover on at all times. If it becomes
necessary to remove the cover, the user should ensure that the cover is correctly
re-fitted before normal operation commences.

Chapter 1. INTRODUCTION
This equipment is designed for maximum reliability and performance in C- and/or
Ku-Band applications.
1.1 DST Overview
The Digital Satellite Terminal (DST) (Figure 1-1) consists of three major components:
DST iProSat
L-Band Satellite Modem – provides conversion of data to L-
Band and delivers power and a 10 MHz reference signal to
the outdoor equipment.
For additional information. Refer to the modem Installation
and Operations Manual
A Block Up Converter (BUC)
Provides frequency conversion from L-Band to C- or Ku-Band and power amplification to a selectable transmit power level.
A Low Noise Block (LNB) Down Converter
Provides frequency conversion of the received signal from C- or Ku-Band to L-Band and power amplification of the signal
with low levels of noise added.
Internet Enabled L-Band Satellite Modem – provides an
Ethernet data interface, L-Band IF interface and delivers
power and a 10 MHz reference to the outdoor equipment.
For additional information. Refer to the modem Installation
and Operations Manual.
