Connectors and wiring
Description of connectors
• Ethernet – Serves for internet connection via cable for operation in a classic computer network
and for configuration of operation on WiFi. The connector supports power supply from the
computer network via PoE.
• Temp/Humidity – Serves to connect up to 3 temperature or humidity sensors. The sensor length
may be up to 60 metres in each port.
• Power – Connector for 5V power supply in the case of power supply from an external adapter.
• Digital Inputs – Serves to connect sensors with digital output.
LED diodes on the front panel
• Link – A green LED signalises connectivity to the computer network.
• Activity – A yellow flashing LED signalises ongoing communication on the cable connection to
the computer network.
• WiFi – A blue LED signalises establishment of a connection to the WiFi connection point. When
establishing a connection, it signalises the state by flashing.
• Alarm LED – Two LEDs hidden in the Port1 and Port2 connectors. Shining LEDs indicate Alarm state.
• Alarm SENS – Shining LEDs signalises Alarm state on one of the temperature or humidity sensors.
• Alarm DI – Shining signalises Alarm state on one of the digital inputs.
Description of button function
• Reset – serves to restore factory settings on the device.
1. Switch the device off.
2. Press and hold the button.
3. Switch the device on and press the button for another 5 seconds.
