General Purpose Input Output (GPIO)

This test connects a special adapter to the device's external GPIO interface and performs a series of continuity tests to ensure that all of the communications pins are functional.

Pass/Fail Criteria

  • All I/O pins must be able to input and output signals as per the device specification.
