4.4.3
Set the configuration of the transceiver to decode data information from a transponder (encoding mode and data
rate).
4.4.4
Specify the header of the data sent by the transponder.
The program will search for the header in the data read from the transponder and display the data with the
header first.
The header is a number of bits that cannot be reproduced in the rest of the ID. For example in the standard norm
ISO11784, the first 11 bits of the ID code will be used as the header and fixed to “0000 0000 001”.
Example: The header is calculated with two parameters. <Header> defining the header in hexadecimal (an entire
number of byte is necessary) and <Nbr Of Unused bit> a decimal number defining the number of bits which are
to be removed from the given Header to form the new Header. Thus, it is possible to define a length of header
different of a power of 2.
HEA0020,5 = 0000 0000
4.4.5
Read, decode and return data from a transponder.
If a problem occurs during operation (no header found, no transponder), an error message will be displayed as
referenced in the table 1.3 Error Instruction.
