Chapter 1. INTRODUCTION
1.1 Description
The Radyne RCS11 1:1 Redundancy Switch provides simple backup redundancy protection for
most configurations of the DMD15, DMD20, DMD50 and DMD2050 Satellite Modems as well as
the DM240XR Video Modulator and DD240XR Video Demodulator. The backup functions of the
RCS11 may be performed manually via the front panel or from the Terminal Mode. Refer to
Figure 1-1 for an illustration of the RCS11 1:1 Redundancy Switch Front Panel, Figure 1-2 for the
Interface options of the RCS11 and Figure 1-3 of a RCS11 Fucntional Block Diagram.
The RCS11 redundant 1:1 switch supports various product configurations that require different
setups. The switch can support a modem, modulator or demodulator only applications.
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 from either the Interactive Front Panel or a remote Terminal
Interface.

1.2 Redundant Power Supplies
The RCS11 is equipped with two fully redundant internal power. 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.
1.3 Front Panel Controls
The Front Panel of the RCS11 provides all of the necessary controls and LED indicators to
provide the operator with online status and backup status of the online and backup Modulators
and deModulators.
