successful. And 1 second RED flash - if there were any faults.
Additional functionality of indicators depends on the application.
Communication interface
The Communication Interface is intended for connection with a device via a serial interface (UART TTL). It
can be used to set the initial settings or update the Application (firmware). Factory programming is also
done through this connector.
The pinout for connecting the data cable is shown in the Table 5
Magnetic sensor
Built-in magnetic field sensor. Designed to activate the device, out-of-order data transmission. May be
used for the purpose of the Application.
Dry Inputs (optional)
Two discrete dry contact inputs. May be absent and not used when connecting an expansion board.
Application-defined.
