The loss of input PSI detection enabled or disabled setting. When enabled, the APEX will check for missing input PSI (PATs and PMTs) based on the PSI detection timeout value. When an input PSI message is determined to be missing, the APEX will assume the input service or services are no longer being streamed and unmap the service(s). This checking only occurs after an initial PSI message has been extracted. Once written, the change to this parameter will take immediate effect. However, 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) @Save(apexSaveConfig, value=2) @File(config.ini, type='ini')
