digital signal, as shown in Figure 2-4.
a. The RUN light flashes once every 0.5 seconds, indicating that the product is powered on successfully;
b. When the NET light of the supporting product is on, it means that the wireless communication between the two
modules is successful;
c. The DI light is on, indicating that the acquisition signal is successful; the DO light is on, indicating that the output
signal is successful;
(3) Notes:
a. For more details on the functions of the indicator lights, see the chapter "Indicator Description";
b. If the NET indicator does not light up, it means that the wireless communication is unsuccessful. It is necessary to
check whether the antennas of the product are installed correctly, ensure that the distance between the antennas is 1 meter
or more, and that there is no obstruction between the antennas of the product.
2.2.5 Step 5: On-site installation
(1) Important knowledge points: The necessary conditions for communication between LoRa wireless spread spectrum
technology paired products: channel, address, and airspeed. Products with the same three parameters can perform data
communication. Conversely, if the parameters are different, data communication cannot be performed. (That is, the LoRa
channel of the transmitter module is the same as the LoRa channel of the receiver module, the LoRa address of the
transmitter module is the same as the LoRa address of the receiver module, and the LoRa wireless airspeed of the
transmitter module is the same as the LoRa wireless airspeed of the receiver module. )
(2) Default parameters: For the default parameter properties of this product, see the nameplate label on the back of the
product for details.
(3) Key point: It is recommended that users configure, record and manage the LoRa wireless spread spectrum channel,
address, and airspeed of the paired product when using this product in engineering.
Reason: to avoid data conflicts between the same type of products in engineering applications and the field environment;
in addition, to avoid forgetting the three parameters of the installed equipment when adding this product next time, which
leads to have to read the parameters on site, causing unnecessary Trouble.
(4) Configuration operation details: For details of LoRa wireless parameter configuration method, please refer to "Driver
and Configuration Software Tool Installation", and the configuration software interface is shown in Figure 2-5 below.
