The Loratech S0 Node is used to read meter pulses and send the recorded data over the LoRaWAN wireless network. Connection INx pulse inputs The pulse outputs of the meter are connected to the INx terminals. They are occupied from IN0 to IN3. It is always important to observe polarity, i.e. connect the + of the counter to the + of the meter. IN0 (P1) - counter 0 IN1 (P2) - counter 1 IN2 (P3) - counter 2 IN3 (P4) - counter 3 Configuration interface Switch the USB- UART converter to 3.
