GeckoFlex 8972PX Protection Switch

The 8972PX is a full-time signal protection switch. It is a highly robust primary/secondary changeover switch for HD-SDI, SD-SDI, or ASI signals. It can be controlled by autonomous switching to a backup signal using in-built detection of signal failure, switched by manual controls, or driven by an external GPI system to switch on command.

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 board 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.

All parameters can be configured via the web browser interface and main parameters via the Newton Control Panel. NetConfig and CommandCenter are supported respectively for remote configuration and product health monitoring. Asserting GPI control or other manual controls will disable autonomous control.

  • 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 (HD/SD-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 board
  • Asserting external control of the board automatically turns off autonomous control
  • Select between primary, secondary, and alternate inputs paths
  • Switch to alternate input (i.e., apology/technical difficulties slide) when primary and secondary inputs are both failing
