Note
Use this command to lock an EPC class1 Gen2 tag on a logical reader.
The tag is locked at the source in which the tag is currently located.
If the given ID is an empty string, all RFID tags in the field of the logical reader will be locked.
Below is a short description of the parameters epcGen2LockAction and epcGen2LockMask.
The first line of the table ('Bit') defines the bit positions of the action and the mask values.
The mask and action values are given with the MSB first.
Bank
Bit
Mask
Action
The mask value determines which of the action value bits should be applied as shown in the
table above as s/w (skip/write with skip=0 and write=1).
The action value determines how the bank should be locked for each memory bank.
The flag r/w defines a password lock for read/write.
The flag w defines a password lock for write (read access allowed).
The p flag defines a permanent lock.
The following tables list possible combinations of r/w and w flags with p flags and their
combined meanings for one memory bank.
The tag is in the open state if it is identified and in the secured state if its access password is
verified.
