RCS11

1:1 Redundancy Switch

Overview

The 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 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.

Features

 1:1 Redundancy Protection for DMD15, DMD20, DMD50, DMD2050, DM240 & DD240 Series

 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.

Power-Up Defaults

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 pushbuttons 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.
