November, 2005: Java & RFID Tags

Hex 0x01 => Start byte
Hex 0x02 => The length in bytes of command and data fields which, in this case, is two.
Hex 0x09 => Binary 00001001
=> LSB 0 and 1: 01 means Read in Continuous Normal mode.
=> Bit 2: 0 means no FBCC calculation.
=> Bit 3: 1 means Power Burst I as specified in the data field.
=> Bits 4, 5, 6, and 7 are all zeros meaning power pause duration not set, Power Burst II not set, no data, and no command extension.
Hex 0x032 => which was decremented by one according to the rule "If the relevant bit in the Command Field is set to '0' the consequent Data Field is omitted, this results in the following data field being moved forward (decremented) by one.
Hex 0x032 represents the Power Burst I.
Hex 0x039 => BCC calculates as follows: 0X02 XOR 0x09 XOR 0x032 = 0x039.
