An Observant field unit will raise an error notification if the field unit can not reliably communicate with its attached devices. 

Types of Communication Errors

Types of device communication errors include:

Error message Meaning
Device Communications Timeout Attempted to communicate but did not get a response.
Device Checksum error Attempted to communicate but got an unintelligible response.
Device Communications Incomplete Attempted to communicate but only received a partial response.

Diagnosing and Addressing Communication Errors

Device communications errors are often a symptom of:

  • Damaged cabling.
  • Dislodged field unit connector(s).
  • A faulty or damaged sensor.

To diagnose and rectify the cause:

  • Ensure that the cabling from the sensor to the Observant field unit is intact and undamaged.
  • Confirm that all connectors to the Observant field unit are firmly seated.
  • If these steps do not resolve the problem, substitute a known good cable and/or device to isolate the problem further.
