RCS11 1:1 Redundancy Switch Description
TM061 Rev. 1.3 Page 1-1
Section 1 - RCS11 1:1 Redundancy Switch Description
1.0 Description
The Radyne RCS11 1:1 Redundancy Switch provides simple backup redundancy protection for
all configurations of DMD15 and DMD2400 satellite Modems as well as the DVB3000 series of
Digital Video Modulators. The backup functions of the RCS11 may be performed manually or
from Terminal Mode.
Operating In the automatic mode, the RCS11 immediately places a backup modem online in
the event of a primary online modem failure. In the Manual Mode, the user may designate the
selected online primary modem either from the interactive front panel or a remote terminal
interface.
1.1 Redundant Power Supplies
The RCS11 is equipped with two fully-redundant internal power supplies that provide +5 Volts to
the system. Each power supply is fully independent of the other, including their source of AC
power and fusing. The RCS11 remains fully-operational as long as either power supply is
providing a source of power. The power supplies are located one on either side of the front of
the RCS11 chassis.
1.2 Introduction
Every attempt has been made to include all of the information that is necessary to properly
operate the RCS11. However, although information is included on theory of operation and
troubleshooting, this is not a service or maintenance manual. Also, the user should be fully
familiar with the operation of the individual Satellite Modems, Modulators and/or Demodulators
that will be connected to the Switch.
Refer to Figure 1-1 for a pictorial representation of the RCS11 front panel, Figure 1-2 for a
Functional Block Diagram of the RCS11 System and Figure 2-3 for an interconnection diagram
of the RCS11 with two satellite modems. Figure 2-4 shows the RCS11 interconnection diagram
with two DVB3000 Digital Video Modulators.
1.3 Manual Format
This manual is divided into five chapters and one appendix, each of which provides information
relating to a different aspect of the RCS11 1:1 Redundancy Switch. The following paragraphs
provide a brief overview of the contents of each chapter.
Chapter 1, Introduction,describes the basic functionality of the RCS11 and outlines other
useful information included in the manual.
Chapter 2, Installation,describes the basic methods for setting up and installing a 1:1 Switch
into a Satellite Modem or DVB system and provides the connector pinout data for various
RCS11 applications.
Chapter 3, Operation,provides the user with technical information necessary for operation of
the 1:1 Switch.
Chapter 4, Basic Maintenance and Troubleshooting Procedures,provides information on
the basic troubleshooting checks and basic 1:1 Switch repairs that the user may make on-site.
Chapter 5, Principles of Operation, briefly describes the internal operation of the RCS11.
Appendix A, Specifications,provides technical reference data on the 1:1 Switch.
Appendix B, RCS11 Remote Communications Specification
Appendix C, RCS11 Dip Switch Setting Tables

Section 2 - Installation
2.0 Installation Requirements
This chapter instructs the user in the methods for setting up and installing an RCS11 1:1
Redundancy Switch into a Satellite Modem system. The cabling configurations for two DMD2400
Satellite Modems, two DVB3000 Digital Video Modulators and two DMD15 Satellite Modems are
shown.
2.1 Unpacking the System
Unseal the shipping cartons taking care not to damage the cartons, the packing material or the
equipment inside. The cartons and the packing material should be saved in the event that an
RCS11 will need to be reshipped. Examine the exterior of the units for any possible shipping
damage.
2.1.1 List of Items
Carefully remove the units from the cartons. In addition to this manual, be sure that the following
items are present:
•RCS11 1:1 Redundancy Switch
•Two AC Power Cords
•1:1 Switch System Test Data Sheet
•RCS11 Standard Cable Set
•Optional ES/ES Interconnection Cables
•75-Ohm Splitter
2.1.2 In Case of Shipping Damage
If any shipping damage is discovered to any of the above listed equipment, promptly contact the
transporter and file a damage claim. The transporter is responsible for any damage caused during
shipping. Radyne Corporation should also be contacted.
Damage as a result of transport is not covered under the Radyne Corporation Warranty. Refer to the
Warranty section in the front of this manual for further information.
The procedure for returning faulty or damaged equipment is contained in the warranty section in the
front of this manual.
2.1.3 Test Data Sheet
Each RCS11 1:1 Redundancy Switch system is shipped with a Test Data Sheet. This report contains
information on the results of the Switch quality control testing. The report also includes information
pertaining to the system settings that were made at the factory. Radyne Corporation recommends
that the user save this report for future reference.
2.2 Site Considerations
Adequate site planning and preparation simplifies the installation process and results in a more
reliable system.
The user should ensure that the site has adequate electrical power, environmental controls and
protection against sources of electrical radiation and interference.
2.2.1 Power Sources
The power sources should be properly grounded and as free as possible from electrical interference.
The RCS11 employs a dual redundant power supply configuration. Each power cord on the RCS11
must be plugged into its own separate power circuit. Each circuit must have its own independent
circuit breaker.

Installation RCS11 1:1 Redundancy Switch
Page 2-2TM061 Rev. 1.3
Grounding is achieved automatically when the three prong power plug is inserted into a power
receptacle. This should be checked by testing that there is no voltage present between the chassis
of the Switch and the power line ground.
*** WARNING ***
The protective ground must not be bypassed with a three-prong to two-prong adapter or defeated In
any way. Defeating the ground may result in operator Injury or damage to the system.
2.3 Rack Mounting
The RCS11 is designed so that it can be mounted in a standard 19-inch rack. The RCS11 is 1-3/4
inches (1U) high.
To allow for the easy installation of cables and adequate air circulation through the units, a minimum
of six inches of clearance must be provided at the sides and rear of the units. In addition, the
RCS11 requires a minimum of 1-3/4 inches (1U) of clearance on top of the unit.
If the Switch is mounted on slide mounts, the cables must be of sufficient length to allow the units to
be pulled forward on the mounts.
2.4 Configuring the system
Figure 2-1 shows the rear panel connectors on the RSC11, and Figure 2-2 shows the front panel
controls and indicators. Figure 2-3 shows the user the proper interconnection of the cables with two
DMD2400 Satellite Modems. Figure 2-4 shows the RCS11 interconnection with the Radyne
DVB3000 Digital Video Modulator.
*** WARNING***
If either AC line cord remains connected to the RCS11, dangerous AC voltages will be present within
the Switch. The top cover of the RCS11 should not be removed for any reason other than fuse
replacement. Refer to Section 4, Basic Maintenance and Troubleshooting.
