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:
