  1. ISO/IEC 15693 standard J.-D. Chatelain

  2. ISO/IEC 15693 Communication softwares between operator’s console and TAG Commands between operator’s console and RWM Commands between RWM and TAG Read/Write Module TAG Operator’s console ISO/IEC 15693

  3. ISO/IEC 15693 Communication interface RWM to TAG • Carrier frequency: 13.56 MHz ± 7kHz • ASK modulation 100% and 10%

  4. ISO/IEC 15693 Coding the information Two types of coding are supported by the transponders fully compliant with ISO 15693: 1 out of 256: one byte is coded at a time Example: coding 197 = <C5> = 11000101 time

  5. ISO/IEC 15693 Coding the information 1 out of 4: two bits are coded at a time 00 01 10 11 Example: coding 197 = <C5> = 11000101 time

  6. ISO/IEC 15693 Start Of Frame (SOF) - End Of Frame (EOF) Start of frame sequence to select the « 1 out of 256 » coding mode Start of frame sequence to select the « 1 out of 4 » coding mode End of frame sequence for both coding modes

  7. ISO/IEC 15693 Communication interface TAG to RWM • Load modulation amplitude: minimum 10 mV • Subcarriers • Data rates

  8. ISO/IEC 15693 Bit coding Single subcarrier Dual subcarrier “0” “1”

  9. ISO/IEC 15693 Start Of Frame (SOF) End Of Frame (EOF) Single subcarrier Dual subcarrier SOF EOF

  10. ISO/IEC 15693 Commands supported by the tag

  11. ISO/IEC 15693 standard End of this chapter J.-D. Chatelain
