SMPTE 269M Fault Reporting MUX-8552A User Manual (Iss. 01)
Jumper Setup
If fault reporting for the MUX-8552A is desired, use main card jumper
JP3
- 269M FAULT
REPORT to set up the card.
1. To access the jumper, remove the card from the frame by pressing down the white
card ejector tab and pulling the card from the frame slot.
2. Observing all static discharge and handling precautions, place the card, with the
components side facing up, on a clean flat surface.
3. To enable SMPTE fault reporting, set jumper JP3 to the ENABLE position.
4. To disable SMPTE fault reporting, set jumper JP3 to the DISABLE position.
Refer to Figure 5 “ MUX-8552A Jumper Locations ”, for jumper location details.
Frame Connections
The SMPTE 269M Fault Reporting connection on RossGear 8000 series frames is provided by the

Details
The fault report contacts are closed when the card detects an internal failure or a power loss condition.
The fault report will pulse off for 1 to 2 ms about every 16ms if the SDI video input signal is missing,
or if both AES signals are missing.
Some internal failures are:
•
Failure of the card to initialize
•
Failure in the fault reporting circuitry
•
Failure to detect a valid video input signal to the card
•
Failure to detect a valid AES input signal to the card with AES selected on JP10
For additional information on alarm system design, refer to the SMPTE document “ ANSI/SMPTE
269M – 1999 ”.
