Answer
Answer Description
Data Serial number (n bytes)
'N' Error: No Tag in the field (only binary protocol)
12.4.3.2.1 Multitag continuous read mode
If the Multitag flag is set in the Protocol Configuration (PCON) register the reader
reads multiple tags continuously.
12.4.3.2.2 Auto start
The continuous read mode is started automatically in ASCII mode. The auto start flag
must be set in the PCON register.
12.4.3.2.3 Noisy Environment
If the Noisy Environment flag is set, the continuous read mode can only be aborted
with the '.' character.
This is only valid in ASCII mode.
12.4.3.2.4 Binary mode
This command is fully supported in binary protocol mode except the test continuous
read command and the noisy environment flag.
Do not use this command on bus system environment in binary mode, because the
continuous read mode will take possession of the bus system.
12.4.3.2.5 Simple access control applications
Serial numbers are always sent plain. Data encryption is activated after a successful
login.
For simple access control applications the use read-only blocks for the identification
of the tag is recommended.
Reading any block (even the manufacturer block) of the transponder will increase
your security.
