User manual GRASS VALLEY 8972PX DATASHEET

[. . . ] 78 8972PX Protection Switch Key Features · Two-input robust failure-proof changeover switch · Third alternate input, available for switching, non relay-protected · Supports HD-SDI, SD-SDI, and DVB ASI with auto-sensing capability · Will maintain signal path in the event of power failure or when the front card is removed · Eight outputs, including: -- One main relay-protected output with passive bypass path -- One electronic output follows main -- Three output pairs can be set to follow main or backup or can be switched to primary, secondary or alternate inputs · Line switching in driven switch mode (SD/HD-SDI syncronous input signals) · External control via GPI or Ethernet · Autonomous control by: -- Signal (carrier) loss detection -- Incorrect signal format -- EDH/CRC error (selectable threshold) -- DVB-ASI PID loss -- DVB-ASI packet loss · GeckoFlex dual-slot rear module · Asserting external control of the module automatically turns off autonomous control The 8972PX is a full-time signal protection switch. [. . . ] The 8972PX fulfils the basic requirement of any protection system by not adding failure modes to the existing signal path. In the event of a power failure, or even if the front control module is completely removed, the Program Output signal will continue to pass from the previously selected input as a fail-safe relay path will latch the selected signal to the output. In driven mode it can be configured by GPI or Ethernet.
