Hi team, 

I'm working on a RFID project for my customer.

Modules Below

RF340R, RF170C,IM154-8 with ICODE SLI Chip Transponder(Icode SLI ISO 15693 13.56Mhz Key Fob Blue ABS (Pack of 10)), FB45.

My Parameter DB is DB1, and my Data DB is DB2 [Array[1..112] as Char.

Starting address on FB= 0

End Address on FB= 111

I set Field_ON_time (DB1)=5 - for ICODE SLI Chip type of Transponder.

Done the init_run

I'm getting below Data from transponder

DB2.DBB0 = ' '

...

....

DB2.DBB108 = 'w'

DB2.DBB108 = '_'

DB2.DBB108 = 'o'

DB2.DBB108 = 'k'

I have 10 Qty of this transponder, all transponder is reading as above data, i dont see any unique values from transponders.

what and where i'm doing mistake to read the unique serial number of all Transponder?

I'm assuming you're using the read command. That means you're accessing the user memory of the tag. I assume they are all initialised with the same data.

To get the UID you can either read

from address 0xFFF0

or

use the mds status command (sub command 3). The UID is then located at byte offset 2.

Fantastic. Working as expected. Thank you all.

can i write our own data into the user memory area? As per document, this kind of Tags are not suitable for writing, Is that right?

Hi, I purchased these Tags from Amazon. and i contacted the Seller of these tags via email, they said, these tags are only readable not writable. Im not sure he is aware of the complete product details.
