Fault Reporting Capability
Fault reporting in the SMPTE 269M standard is available on this card. This is a simple system, which can
indicate that one, or more of the modules in the rack frame has encountered a fault or abnormal condition.
Each rack frame has a "telco" connector, which can be connected to an external "contact closure" type of
alarm system. A customer-devised system of lights can be used to trace a fault to a rack cabinet, rack
frame, then a particular card. For more information on designing such a system, refer to SMPTE
document ANSI/SMPTE 269M - 1994.
If the FAULT REPORT jumper (JP1) is enabled, the output will be a steady low signal if there is no
power in the module. The output will pulse at a field rate if the input signal is very low or absent. In all
other situations, the output is open (high impedance).
All frame modules having fault reporting capability are connected in parallel to the "telco" connector.
Maintenance and Repair
Routine maintenance is not required. If the module does not appear to be working properly, return it to
Ross Video Ltd. for repair. All Ross digital distribution products are covered by a generous 5-year
warranty and will be repaired without charge for materials or labor in this period. See "Ross Gear
Terminal Equipment - Warranty and Repair Policy" in this manual.
