• Start the reader with the command RD plus Parameters ( plus <CR>). see example

- You can read out one block of the transponders memory, if the address of only one

. block is sent to the reader.

– You can read out several blocks, if the first and the last block to read is sent to the

reader. So it’s also possible to read out the whole memory of the transponder.

• Wait for the answer

The NoRead Code is set to ( „XXXXXXXX“) ..

The result of the reading process may also be seen at the LED’s.

7.1.4.3 Writing Process WD

The memory of the transponder is organised in blocks, containing 32 bits. The data’s of every

single block must be changed separately.

• Start the reader with the command WD plus Parameters ( plus <CR>). See also example

The sent parameter consists of the block address and writing data’s (8 ASCII characters).
