    Chapter 1. INTRODUCTION 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.

  • Page 22: Power-Up Defaults

    RCS11 1:1 Redundancy Switch Introduction Power-Up Defaults During power-up, the RCS11 initializes itself to the last mode set by the Front Panel Pushbuttons. For example, if the operator desires the RCS11 to operate in the Auto Mode, with both the Modulator and Demodulator 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.

    Appendix A. RCS11 DIP Switch Configuration The RCS11 has four internal DIP switches that are accessible only by removing the top cover. These DIP switches S2, S3, S4 & S5 are used to configure Interface options, data rates and remote baud rates. An upgrade or change from an existing interface or configuration to another may require a change to one or more of the DIP switch settings.

    RCS11 1:1 Redundancy Switch RCS11 Remote Communications B.1.2 Protocol Wrapper The Radyne COMMSPEC is byte-oriented, with the Least Significant Bit (LSB) issued first. Each data byte is conveyed as mark/space information with two marks comprising the stop data. When the last byte of data is transmitted, a hold comprises one steady mark (the last stop bit). To begin or resume data transfer, a space (00h) substitutes this mark.

  • Page 98: Global Response Operational Codes

    RCS11 1:1 Redundancy Switch RCS11 Remote Communications To reiterate, valid equipment responses to a message require the FSN tag in the command packet. This serves as part of the handshake/acknowledge routine. If a valid response message is absent, then the command is re-transmitted with the same FSN. For a repeat of the same command involving iterative processes (such as increasing or decreasing the transmit power level of a DMD15 modulator), the FSN is incremented after each message packet.

    RCS11 1:1 Redundancy Switch RCS11 Remote Communications B.1.5 Software Compatibility CAUTION The DMD15 RLLP is not software-compatible with the following previous Radyne products: RCU5000 and DMD4500. These products may not occupy the same while using this protocol as equipment malfunction and loss of data may occur. The COMMSPEC, operating in conjunction within the RLLP shell, provides for full forward and backward software compatibility independent of the software version in use.
