About

This connector can be used to monitor the activity of the Double D Electronics DDA289 redundancy controller.

The connector uses serial communication and allows the end user to switch positions and view the status of the device's converters.

Three polling intervals are used to gather data at different rates:

  • Every 5 seconds: Captures rapidly changing information, such as switch positions and converter status information.
  • Every 1 minute: Retrieves the summary status of the controller.
  • Every 1 hour: Collects data that changes infrequently, such as controller configuration data.
