Operational Description
The REIMS Module is a basic demonstration platform for the MXYP8300 device. Two
module configurations are available, 315MHz and 434MHz transmit frequency versions.
All other features and operational characteristics are the same for the modules. The
MXYP8300 device integrates pressure, temperature, and accelerometer sensors with a
HCS08 MCU, wireless ISM band RF transmitter, and wireless LF band 125KHz
receiver. Typical application provides for measurement data to be transmitted to a
system host. The transmissions are sent at a slightly random time interval greater than
10 seconds and/or may be keyed by reception of a 125KHz LF reception. Either
method will meet Agency approval requirements for transmitter certification.

Module power is derived from the on-board 3V battery. The MXYP8300 monitors the
battery and will not operate or transmit if too low. Option JP1 allows the module to be
powered on or off. During development port connection the BDM may provide 3.3V to
the module to save the battery. The transmitter should not be applied during
development port connection due to possible RF coupling into the development cable.

Agency approved operation of the transmitter applies fixed power setting with +/-35KHz
FSK modulation from center carrier frequency. The module 125KHz receiver coil
should be at least 6 inches from the 125KHz transmitter applied or overdriving the
detector is possible.

The REIMS TPMS demonstration software and application documentation package
provides all necessary functions, operations, and controls to operate the module
correctly. Preset software definitions and C language function calls provide an easy
method to modify or adjust operation for particular applications. Default software
settings for TX Power or Frequency must not be modified or the module Agency
approvals are void and the application may violate government regulations.
