RST / FACT DFLT Signal
The ATOMAS-MINI provides a reset signal input. To trigger the reset signal, short the RST pin
to the GND. The reset signal can be used to perform a device reboot, or to perform a complete
reset to factory default settings of the device's configuration parameters.
To reboot the device without triggering a factory reset, short the RST pin of connector J1 and
immediately release. The device should perform a complete reboot.
To reset the device to the factory default configuration, short the RST pin of connector J1 for
approx. 20 seconds – release the pin once the LED pattern on the on-board LED displays
alternating RED/GREEN colors. After the device reboots, it should be reset to the default factory
configuration.
In addition to the RST pin of connector J1, there is a push button (SW1) that allows you to
perform either a device reboot or a complete reset to factory default settings. To reboot the
Atomas press the button and immediately release it, the LED will flash red, then will turn steady
greed to indicate the reboot is finished. To perform a factory reset, press the button and release
it as soon as the on-board LED displays alternating RED/GREEN colo. Once the device finishes
rebooting, it will be configured to default settings.
MEZ DRY OUT Signal
The ATOMAS-MINI provides a digital output for providing functionality such as driving a relay.
The open state of the I/O output is at 3.3V and the closed state is to the board ground (GND).
The below schematic excerpt describes functions of the I/O OUT exposed via J1
