Principle of operation
Stage 1: Device LED blinks very slow. This stage means that device is searching connected sensor.
To correctly connect sensor: connect ground wire, then connect both RS485 wires and then connect power wire.
Stage 2: Device LED blinks very fast. Device waits for pressed button in this stage. There are three buttons. Button 1 set device address to 0x21 and 0x26; Button 2 set device address to 0x22 and 0x27; Button 3 set device address to 0x23 and 0x28.
Stage 3: Device LED blinks slow. Device tries to change sensor address.
Stage 4: Device LED is turned on always. This means that address changed successfully.
To correctly disconnect sensor: disconnect power, then disconnect both RS485 wires and then disconnect ground wire.
Then device goes to stage 1.
Process again with another sensor in same order.
