Issue / Question

Locking Monza R6 Tags

Applicable To

ZD500R, ZT410R, ZT420R, ZT610R and ZT620R

Resolution / Answer

Monza R6 tags do not give the ability to lock each memory bank separately like other Gen2 chips. They only provide a method to permalock all of the memory.

The ^RLM command previously had 4 parameters (^RLM,k,a,e,u) that represent the function for each of the memory areas of a tag: kill password, access password, EPC Memory bank, User Memory bank.  The TID memory of a tag is always permanently locked at the chip manufacturer, but in order to lock the Monza R6 tag, we need to specify that explicitly in the command sent to the reader.

The change implemented for Monza6 extends the ^RLM command to have a 5th parameter, ‘t’, which represents the TID memory bank. Then if a user wants to permalock a Monza 6 tag, they would specify ^RLM,P,P,P,P,P

Please refer to the latest version of the RFID Programming Guide 3 for full details of using the ^RL command.
