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