DMD2050 Universal Satellite Modem Introduction
TM110 – Rev. 1.3 1-1
Introduction 1
This chapter provides an overview of the DMD2050 Universal Satellite Modem. The DMD2050
may be referred to in this manual as the DMD2050 or “the unit”.
1.0 Overview
Radyne 's new DMD2050 Satellite Modem (Figure 1-1) breaks new ground in flexibility and
performance. With standards based upon MIL-STD-188-165A and the ability to run commercial
industry standard functions including IDR, IBS and DVB, while covering data rates up to 52 Mbps,
this duplex modem covers virtually all Satellite IP, Telecom, Video and Internet applications, while
allowing switching between spur-free 70/140 MHz operation to L-Band without any configuration
changes.

The extensive list of software options allows for the deployment of a modem with today's needs
while keeping an eye toward tomorrow. Additional options and configuration (such as Monitor
and Control (M&C) Functions) can be activated in seconds via the front panel. Additional
hardware options like Turbo, Interface Expansion, and DC operation complete the modem's
dynamic feature coverage.
The DMD2050's impressive remote accessibility surpasses all others in the field. Remote control
via Radyne 's trusted RLLP (Radyne Link Level Protocol), Ethernet 10 Base-T SNMP and Web
Browser includes control of all the modem's features plus software maintenance. Additionally,
the Vacuum Flourescent Display (VFD) can be supplemented with terminal software running on a
PC or laptop.
The modem now presents its entire monitor and control functions on the big screen. Supported
by Radyne 's extensive line of redundancy switches, converters, encoders and decoders, the
DMD2050 can be built into any satellite requirement. Compatibility with current modems, such as
Radyne 's DMD50, DMD2401, DMD15, and DISA certified MIL-188-165 compliant DMD15L are
maintained for seamless substitution and addition to existing systems.
A full range of Industry Standard Interfaces is available for the DMD2050. Interface types are
selectable from MIL-188-114A, ITU G.703, HSSI, ASI, DVB/M2P and Ethernet Bridge.

1.1 DMD2050 Configurations
The DMD2050 can be configured in the following different ways:
features and options that are installed when the unit is ordered
feature upgrades
hardware options that the user can install at their own location
options that are installed to a unit that is sent to a Radyne facility
1.1.1 Features/Options Installed at Time of Order
Features installed at the time of ordering are the options pre-installed/initialized in the factory prior
to shipment. These can be reviewed from the front panel. Refer to Section 4, User Interfaces for
information on how to view these features.
Factory installed options are chassis and board configurations that are introduced during
manufacture.
1.1.2 Feature Upgrades
Feature Upgrades are a simple and quick way of changing the feature set of an installed modem.
Feature upgrades are how most DMD2050 options are implemented. Features may be
purchased at any time by contacting a Radyne Inc. salesperson. Refer to Section 4 and
Appendix D, for information on how upgrade features.
1.1.3 Hardware Options
Hardware options (refer to Appendix A) are purchased parts that can be installed into the unit at
the customer’s site. A screwdriver is normally the only tool required. Please contact the Radyne
Inc. Customer Service Department for information not limited to availability and to shipping costs.
Only authorized service personnel should handle and install optional
hardware options.
1.1.4 Radyne Installed Options
Units may also be sent to the Radyne Inc. facility for hardware option installation. Please contact
the Radyne Inc. Customer Service Department for information not limited to availability and to
shipping costs.
1.2 Function Accessibility
All functions can be accessed with a terminal or personal computer via a serial link for complete
remote monitoring and control capability.

Installation 2
This section provides instructions on unpacking and installation, as well as storage of the unit.
2.0 Installation Requirements
The DMD2050 Modem is designed to be installed within any standard 19-inch (48.26 cm) wide
equipment cabinet or rack. It requires 1 rack unit (RU) of mounting space (1.75 inches/4.45 cm)
vertically and 19.25 inches (48.89 cm) of depth. Including cabling, a minimum of 19.5 inches
(49.53 cm) of rack depth is required. The rear panel of the modem is has power entering from
the left and IF Cabling entering from the right (as viewed from the rear of the unit). Data and
Control Cabling can enter from either side. The modem can be placed on a table or suitable
surface if required.
There are no user-serviceable parts or configuration settings located
inside the DMD2050 Chassis. There is a potential shock hazard internally
at the power supply module. DO NOT open the DMD2050 Chassis under
any circumstances.
Before initially applying power to the unit, it is a good idea to disconnect
the transmit output from the operating ground station equipment. This is
especially true if the current DMD2050 configuration settings are
unknown, where incorrect settings could disrupt existing
communications traffic.
