Fault Reporting Output
The fault-reporting optically-isolated output is accessible at the rear RJ11
connector of the FR-680X series frame. RJ11 pins 3 and 4 are used as
negative and positive terminals respectively.
The output is open when no errors are occurring, is closed with frame
power removed, and pulses closed for the duration of a field with EDH
errors (as configured by the FF/AP jumper).
Figure 3-2 illustrates a basic interface:
