7.2.1. Magnetic Strip Emulation
Data Format:
The following table shows data coding depending on DC-FORMAT
For cutting the length of data output the parameters D_LGT and D_START (see chapter
7.10.
CFG11: Read Mode – Read Data) are used. D_LGT and D_START are the number
of Bits to be read and the Start Bit.
