The Comtech RCS11 1:1 Redundancy Switch provides simple backup redundancy protection for all configurations of DMD15, DMD20, DMD50 and DMD2050 SCPC modems and the DM240 / DD240 DVB series of Digital Video Modulators and Demodulators. The backup functions of the Comtech RCS11 may be performed automatically, manually or from Terminal Mode.
Operating in the automatic mode, the RCS11 immediately places a non-faulted 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.
Radyne RCS11 1:1 Redundancy Switch Features:

- Automatic or manual modes of operation
- Self-contained dual redundant power supplies
- Manual operation from front panel or remote control
- Independent (mod/demod) or coupled (modem) backup capability
- IF options – 70/140 MHz or L-Band
- Supports 10/100Base-T Ethernet switching
Redundant Power Supplies
For maximum reliability, the RCS11 is equipped with two fully-redundant internal power supplies. Each power supply is fully independent of the other, including their source of AC or DC power and fusing. The RCS11 remains fully-operational as long as either power supply is providing a source of power.
Front Panel Controls
The front panel of the RCS11 provides all of the necessary controls and LED indicators to provide the operator with online and backup status of the online and backup modulators and demodulators.
During power-up, the RCS11 initializes itself to the last mode set by the front panel push buttons. For example, if the operator desires the RCS11 to operate in the Auto Mode, with both Mod and Demod set to Modem B, the operator places the RCS11 into this condition using the front panel push buttons and the RCS11 stores this configuration into nonvolatile memory. If the power source was then to fail and be restored, the RCS11 would again power-up in the Auto Mode with both Mod and Demod set to Modem B.
