Operation
Q – Queries of the
output status
The current status of an output can be queried by using the Q command. The
status of the outputs of a single antenna port or the entire device can be queried.
For a single antenna port, the reader reports the status of the output. Use the
Head ID 0 to query the status of all outputs of the reader. The status of each
output is represented by 3 characters (status + flash rate).
