NEW MilesTag II Data Protocol
Infrared Carrier Signal
The carrier frequency is selectable between 38KHz/40KHz/56KHz.
The system's transmit carrier frequency must be matched to the sensor used.
Data Packet
The MilesTag II "shot" packet consists of a header pulse followed by 14 data bits. A "control packet" consists of a header pulse followed by 16 data bits or more. The header pulse and data bits are encoded onto a 56KHz infrared carrier signal using pulse-length modulation. This modulation is similar to the format used in many IR remote controls.
Pulse-Length Modulation
In this modulation scheme, the value of the data bits ("1" or "0") and the header pulse are represented by the length of the pulse. Each pulse is a burst of 56 KHz infrared light lasting the period (length) of the corresponding data bit.
The Header Pulse is represented by a pulse (56 KHz carrier ON) with a period of 2400 uS (microseconds).
A bit value of "1" is represented by a pulse (56 KHz carrier ON) with a period of 1200 uS.
A bit value of "0" is represented by a pulse (56 KHz carrier ON) with a period of 600 uS.
The space (56 KHz carrier OFF) between each of the bit pulses is 600uS.
