This command involves a RF session with either the tags or seals.
For that reason, the READER carries a Long Command. The
READER responds with an ACK if the command was successfully
received.
Reader > LSC
STX #B R# MSGT(XX20h) R_status channel CRC ETX
1 2 2 2 2 1 2 1 # of bytes
In case of an ACK with an error response:
STX #B R# MSGT(XX20h) R_status Err code CRC ETX
1 2 2 2 2 1 2 1 # of bytes
The final results of this command will be ready later. The LSC
should use the GET RESULTS command to retrieve the results.
For detailed error codes see para 5.4.
NOTE: In the Data Field, #B includes the Time & Data and ADI fields.
