For further security, pins 1 and 9 (ground) of the GPI/O ports can be used to control a unit fault alert. If pin 1 goes “low,” then a power supply or hardware fault has occurred. These can be used on both the encoders so that a faulty standby encoder can be identified before it is required. Pins 3, 4, and 9 can also be used to ascertain whether the unit is producing an encoded output, and trigger a warning on the console or monitor system.

4.4DP570

The DP570 has fixed connections on the GP output for fault and error conditions (pins 2 and 3, respectively). For critical live applications, the system design should be such that the DP570 is only part of the monitor path or that these pins can be used to trigger routing to bypass the main audio around the DP570.

4.5DP571

The status port can be used to control a router, console, or other switching device in the event of a unit failure. Pins 4, 5, and 9 (ground) can be used to check whether a unit is operational. If pin 4 or 5 goes “low,” then either the system is not operational, a hardware fault has occurred, or power has been lost to the unit. By monitoring these pins on both the units, an operator can be alerted to problems with either unit.

4.6DP572

The DP572 can be used in the same way as the DP571.
