MS-RA1xM Datasheet
Pin 6 / Pin 7: I/O1 / I/O 2
Pin 6 and pin 7 are used for general-purpose user I/O interface signals. These pins are connected to
the A/D converter, and thus can be used for analog input signal interface. For instance, pin 6 and pin 7
can be used for temperature measurement with a thermistor or other analog devices.
Pin 8: Velocity Out
A signal is produced if the speed of a detected object falls within the velocity range set by the user. The
velocity range can be adjusted from the provided GUI interface. The default value ranges from 1 km/h
to 6 km/h.
Pin 9/ Pin 10: Tx/ Rx for Command Control Interface
The MS-RA1xM module is capable of interfacing various information with external MCUs through serial
communication. Pin 9 and pin 10 support this interaction. Information about the motion and speed of
detected objects can be exchanged in real time with external MCUs, and the range of detection can
also be configured in real time.
