How can G2im+ be written for unique EPC id codes?

[加鹏孙]

I'm desigen tags using the IC G2iM+，i want use the tags mark some defffient products。But now all the tags have the same EPC ID(HEX E200 680B 0000 0000 0000 0000) at the memory Bank 01 address 20h to 7Fh.So i must change the EPC ID,but when i writen the new ID(such as: HEX 1111 2222 3333 4444 5555 6666) to the address 20h to 7Fh,the tags well never be find by the reader. it seems the tags has been damaged. so how can i change the EPC ID now?
