Operator’s console Read/Write ModuleTAG Commands between RWM and TAG Commands between operator’s console and RWM ISO/IEC Communication softwares between operator’s console and TAG

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

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 = = time ISO/IEC Coding the information

1 out of 4: two bits are coded at a time Example: coding 197 = = time ISO/IEC Coding the information

ISO/IEC 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
