
Magnetic Anomaly Determination establishes if a transient magnetic distortion is
present and accounts for it.

Configuration RAM allows for customizing SENtral to match the specific sensors
being used and allows the user to tailor certain parameters for their specific system.
The SENtral Configuration Tool generates the SENtral Configuration File, and this is
subsequently uploaded into SENtral’s Configuration RAM.

Pass-Through allows for direct communication with devices on the sensor bus by
connecting SENtral’s I
2
C Host Interface to the Sensor Interface.

Host Interface communicates with the host system. Data is transmitted between the
host and SENtral via the host I
2
C bus, in which the host acts as the master and
SENtral acts as a slave device. SENtral signals the host that new data is available by
sending an interrupt signal on the host DRDY line.

Sensor Interface communicates primarily with the sensors. Sensor data is
transmitted from the sensors to SENtral via the sensor I
2
C bus, in which SENtral acts
as the master and the sensors as the slave devices.
