ADDRESS QUERY COMMAND (?!)
While disconnected from a bus, the address query command can be used to determine which sensor you
are currently communicating with. Sending this command over a bus will cause a bus contention where all
the sensors will respond simultaneously and corrupt the data line. This command is helpful if you are trying
to isolate a failed sensor. Here is an example output from one of our sensors (the logger command is in
bold):
