Introduction
The device calibrates and processes signals using a number of algorithms specifically designed
to provide for high survivability in the face of adverse environmental challenges. User-defined
Setups are employed to alter these algorithms to suit each application. These Setups are loaded
into the device over the I2C-compatible serial interfaces. In standalone these settings are fixed to
predetermined values.
