7.1.4.2 Selective Read RD

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

below.

- 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

• Analyse the received answer: 8 characters plus <CR>. Allowed characters 0 to F.

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

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

• LED L2 lit, if there was a successful read.

• LED L3 lit, if there was a No Read.

Example RD <SP> 20 <CR> read block 20

RD <SP> 16 <SP> 33 <CR> read all blocks from 16 to 33

Allowed Values (block numbers of the transponder IC):

ALGO 9 (1kBit Memory) 3 .... 33

Serial Number block 32

ALGO 6 (2kBit Memory) 16 ... 63

Serial Number block 1

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

below.

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

Note! There must be a blank between the block address and the writing data’s..
