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