Enables RF redundancy mode, allowing the APEX to failover to backup RF port and communicate with the REM1000. Allows for failover/ switching without requiring a REM1000 connection. Cannot be 'enabled' if the backup port (RF Port 6) is not present (there is no QAM Module in QAM slot 3). Cannot be 'enabled' if there are any mappings to any QAM Channel on the backup port. RF Port 6, QAM Channels 6A to 6H (Output Transport Streams 41 to 48). Once written, the change to this parameter will only take immediate effect after apexQamRfRedundConfigApplyChange is set to 'apply'. In order for the change to persist through subsequent reboots or power cycles, the change must be saved via the apexSaveConfig parameter. @Config(config=yes, reboot=no) @Commit(param=apexQamRfRedundConfigApplyChange, value=2) @Save(apexSaveConfig, value=2) @File(config.ini, type='ini')
