Notifications
- TX LED flashing and RX LED ON: Initialization and reading of configurators
- RX LED flashing and TX LED ON: Waiting for instructions
- Both TX and RX LEDs flashing at the same time: Application code missing
- TX and RX LEDs flashing in alternation: Performing flash type cancellation
- TX LED ON: Transmitting
- RX LED ON: Receiving
During execution:
- Both TX and RX LEDs ON at the same time: Initialization and reading of configurators
- Both TX and RX LEDs flashing at the same time: Receiving control
- Both TX and RX LEDs OFF: Communication missing
The red LEDs associated to the relays turns on and off based on the closed/open status of the corresponding relays.
