Overview
The SMPTE 269M Fault Reporting system, also known as a SMPTE “alarm”, indicates if one or more
frame modules encounter a fault or an abnormal condition. The
DAC-8013A
provides a jumper to
enable SMPTE-269M fault reporting. The card connects by means of an internal interface circuit to an
auxiliary
telco connector on RossGear 8000 series frames. When the frame
connection is interfaced
with a customer-designed system of LEDs or audible alarms, faults can be traced to a specific frame
when a card fault occurs within that frame.
The following diagram illustrates a general arrangement for SMPTE 269M alarm reporting:
