Full description table

For wired protocols: such as Ethernet RJ45, KNX, M-Bus, Modbus RS485, and LPB (X-Bus), the LEDs blink when there is traffic on the bus and remain off when in standby mode.

For wireless protocols: The LoRaWAN LED is not monitored, so it remains off, while the GSM LED blinks when connected to the GSM network.

For box status: The power supply LED should be on, and the Heartbeat LED should blink.
