Preface MN-RCS20
The user should carefully review the following information.
Safety and Compliance
Electrical Safety and Compliance
The RCS20 complies with the EN 60950 Safety of Information Technology Equipment
(Including Electrical Business Machines) safety standard.
IF THE UNIT IS OPERATED IN A VEHICLE OR MOVABLE INSTALLATION,
MAKE SURE THE UNIT IS STABLE. OTHERWISE, EN 60950 SAFETY IS NOT
GUARANTEED.
Electrical Installation
The RCS20 is rated for a nominal operating range of 100-240 volts AC; for the appropriately
equipped DC option, nominal operating range is 48 ±5 volts DC. The unit has a maximum power
consumption of 250 watts.
The installation and connection to the line supply must be made in compliance to local or national
wiring codes and regulations.
The RCS20 is shipped with line inlet cables suitable for use in the country of operation. If it is
necessary to replace these cables, ensure the replacement has an equivalent specification.
Examples of acceptable ratings for the cables 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.
Battery
The RCS20 contains a Lithium Battery. DANGER OF EXPLOSION EXISTS
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.
if the
Grounding
PROPER GROUNDING PROTECTION IS REQUIRED: The installation
instructions require that the integrity of the protective earth must be ensured and
that the equipment shall be connected to the protective earth connection at all times.
It is therefore imperative

into the body of the IEC power inlet module.
• For DC operation, no fuses are required.
Operating Environment
DO NOT OPERATE THE UNIT IN ANY OF THESE EXTREME OPERATING
CONDITIONS:
• AMBIENT TEMPERATURES LESS THAN 0°C (32°F) OR MORE THAN
50°C (122°F). (MAXIMUM STORAGE TEMPERATURE ALLOWED IS 20°C (-4°F) TO 70°C (158°F)).
• PRECIPITATION, CONDENSATION, OR HUMID ATMOSPHERES OF
MORE THAN 95% RELATIVE HUMIDITY.

1.1 Overview
The Radyne RCS20 M:N Redundancy Switch provides backup switching/protection for up to
nine pairs of satellite modem channels (modulators/demodulators). The RCS20 is a companion
product to the Radyne DD240, DM240, DMD15, DMD20, DMD2401, and DMD50 units. The
RCS20 may be referred to in this manual as the RCS20, “the switch”, or “the unit”.
The RCS20 can be operated automatically, in which case an automatic backup of a failed online
modem occurs after a preprogrammed delay. The switch may also be operated manually,
allowing the operator to manually switch to a backup modem.
1.2 Features
• Backup Switching Protection for up to Nine Satellite Modems (1 for 9 Protection)
• Flexible Backup Configuration, 1:9, 2:8, 2 x (1:4), etc.
• Large Display With Easy-to-Use Menu Structure
• Automatic or Manual Modes of Operation
• Flexible Automatic Configuration Mode
• Independent Modulator and Demodulator Switching
• Two Fully-Redundant Power Supplies
• Passive Relay Switching for Terrestrial and IF Signals

1.3 RCS20 Switching System Components
The RCS20 is comprised of three separate units that make up the switching system:
• The Redundancy Control Unit (RCU20);
• The Digital Data Switch (DDS20);
• The Intermediate Frequency Switch (IFS20).
1.3.1 RCU20 Redundancy Control Unit
Front panel controls and indicators provide for auto/manual configuration, as well as display of
online/off line status information for all modems in the Redundancy configuration.

Introduction MN-RCS20
1.3.2 Digital Data Switch (DDS20) Configurations
The DDS20 provides all of the data interconnections between the online and backup modems.
The DDS20 also provides buffering of terrestrial data signals to backup modulators allowing
‘hot-standby’ modes of operation. The DDS20 receives control and DC power through an
interconnecting cable from the RCU20. Terrestrial interface options for the DDS20 include the
following options:
• Universal Interface: RS-449, V.35, RS-232, IDR & IBS Alarms
• ASI Interface: BNC Female
• G.703 Interface: Unbalanced T1, E1, T2, E2, T3, E3, STS-1
• Ethernet: RJ45 - 10/100/1000 Base-T.
The DDS20 is available in the following three configurations:
• Universal DDS20
• DDS20-ASI-M or DDS20-G.703-M (Modulator only)
• DDS20-ASI-D or DDS20-G.703-D (Demodulator only)

1.3.3 Intermediate Frequency Switch (IFS20) Configurations
The IFS20 Intermediate Frequency Switch interfaces the IF signals of the modems with the Earth
Station IF system and provides backup switching. The RCU20 can be configured with or without
the IFS20. When the system does not require independent uplink and downlink ports, then the
RCU20 will monitor the status of the primary modem and ensure backup when a primary modem
faults.
When the system is configured with an IFS20, it will provide all of the switching relays and
optional signal splitters that are necessary to connect any combination of up to nine Modulators
and Demodulators to nine independent uplink and nine independent downlink transponders. The
IFS20 receives control and DC power through an interconnecting cable from the RCU20. The
IFS20 is available in the following three configurations:
1.3.3.1 70/140 IFS20
The IFS20 configuration is used for 70/140 MHz.
