Axioma Qalcosonic W1 Ultrasonic Water Meter: Instructions for Successful LoRa Connection

Place and hold the optical head on the meter, and connect it to the USB port.

Start the W1 Tool. In the 'Com Port' window, enter the number of the virtual serial port. This number can be found in the Device Manager under the 'Ports (COM & LPT)' section, typically listed as 'USB Serial Port (COMx)'. Use only the numerical part (e.g., '3' if it's COM3).

[Description of W1 Tool 'Main Settings' tab screenshot: Displays the W1 Tool interface with tabs for 'Main Settings', 'Radio', 'Menu', 'LORA WAN'. The 'Main Settings' tab shows a 'Com Port' selection, 'Time' settings, and operational buttons like 'Enter Test Mode', 'Enter User Mode', 'Wake Up Meter', 'Read ID', 'Read All', 'Write All'.]

Press the "Wake Up Meter" button, followed by the "Enter Test Mode" button, and then "Read All". The sections for "Enter Test Mode" and "Enter User Mode" should show a yellow highlight.

Navigate to the "Radio" Tab. Press the "Get Radio State" button to check if the radio is activated. If it is not activated, press the "Activate Radio" button.

[Description of W1 Tool 'Radio' tab screenshot: Shows the 'Radio' tab selected. Options include 'wMBus T1', 'wMbus S1', 'Lora Wan', 'AES Enable', 'Activate Radio', 'Get Radio State', 'Radio State'. It also displays various configuration masks like 'Param Mask', 'Month Mask', 'Week Day Mask', and a 'Battery Life Time Calculator' section with settings like 'SF 12', 'Payload Len 51', 'Period, s 3600'.]

If you are starting from this step, follow steps 1-3 from Chapter 1. Then, go to the "Radio" Tab and ensure the "Lora Wan" checkbox is marked (active). If it is not checked, mark it to activate LoRa communication on the meter.

If LoRa was not activated and you have initiated the activation process, go to the "Main Settings" Tab. Write the new configuration data to the meter by pressing the "Write All" button.

If you are starting from this step, follow steps 1-3 from Chapter 1. If the radio signal is active, the next step is to verify that the LoRa keys on the meter match those on the server. To find the meter's keys, navigate to the "LORA WAN" Tab and locate the "Network key" and "AppS key" sections. Compare these keys with the ones configured on your server.

[Description of W1 Tool 'LORA WAN' tab screenshot: Displays the 'LORA WAN' tab with fields for 'Network key', 'AppS key', 'Dev Eui', 'App Eui', 'App Key', 'Tx Duty Cycle(send period),s', 'Network ID', 'OTAA enabled', 'Default bitrate', 'Region', 'Confirm MSG On'. Specific values are shown for these parameters.]

If the keys are different, you must reinitialize LoRa communication. Follow the instructions in Chapter 5 for further guidance.

To ensure correct data transmission (telegrams), verify that the send period and store period are set according to your requirements. If starting here, follow steps 1-3 from Chapter 1 and confirm that LoRa Wan is activated in the "Radio" Tab.

To check specific settings, go to the "LORA WAN" Tab and find the "Tx Duty Cycle (send period)" and "Lora Store period" fields. If these periods do not meet your needs, adjust them by entering the desired time period in seconds.

[Description of W1 Tool 'LORA WAN' tab screenshot (showing settings): Shows the 'LORA WAN' tab with highlighted fields for 'Tx Duty Cycle(send period).s' (e.g., 10800) and 'Lora Store period,s' (e.g., 3600).]

After adjusting settings, go to the "Main Settings" Tab and press the "Write All" button to apply the new configuration data to the meter. Alternatively, you can follow the instructions in Chapter 5 after pressing "Write All".

After changing any settings, or if you are experiencing a lack of connection with the server, press the "Reinit LORA" button located in the "LORA WAN" Tab. Ensure the meter is in "Test mode" and that steps 1-3 from Chapter 1 have been completed. This action will reinitialize the connection and reset the meter's communication with the network.

[Description of W1 Tool 'LORA WAN' tab screenshot (showing Reinit LORA): Displays the 'LORA WAN' tab with the 'Reinit LORA' button highlighted.]

The meter should now attempt to use the new configuration settings and re-establish its connection with the network. If the meter fails to respond during this process, use the "Wake Up Meter" button again.

Before exiting the W1 Tool, remember to return the meter to "User mode" via the "Main Settings" Tab.

If you are starting from this step, follow steps 1-3 from Chapter 1. To switch between ABP (Activation By Personalization) and OTAA (Over-The-Air Activation) authentication methods, navigate to the "LORA WAN" Tab. Locate the "OTAA enabled" field. Enter '1' if you wish to enable OTAA, or enter '0' if you want to disable OTAA and use ABP authentication.

[Description of W1 Tool 'LORA WAN' tab screenshot (showing OTAA enabled): Shows the 'LORA WAN' tab with the 'OTAA enabled' field highlighted, showing a value of '0'.]

After making the desired change, go to the "Main Settings" Tab and press the "Write All" button to save the new configuration data to the meter. You can also follow the instructions in Chapter 5 after pressing "Write All".
