The device is already configured so it is not need it to carry out the configuration. For further information, please check section 4 of the manual.

LORAWAN SENSOR INSTALLATION

In this section, the installation process of the device is explained. Before installing, please check the part list to ensure nothing is missing.

PACKING LIST

• a. Master Terminal Unit (MTU)
• b. Remote Terminal Unit 1 (RTU 1)
• c. Remote Terminal Unit 2 (RTU 2)
• d. Remote Terminal Unit 3 (RTU 3)

EQUIPMENT INSTALLATION
In this section, the installation process of the device is explained. Please, click on the following link to see the installation process: TBC

The device is ready to be installed in grain warehouses. The process is as follows:

• A pipe with sensors is introduced into the grain.
• The Smart Warehouse Device is located on the top of the pipe as is shown in following image.
• The device covers an area of 8m of diameter and 350 Tons of grain: ****

LORAWAN SENSOR CONFIGURATION

In this section, the configuration of the device is explained.

DEFAULT CONFIGURATION
After powering the device, the led will light up in all possible combinations. Then, the device will try to connect to the LoRa gateway, the led will blink red during the process. As soon as it is connected to the network, it will send an uplink message and the led will flash green. Then, it will send frames every 6 hours.

DOWNLINK COMMANDS TO CHANGE THE CONFIGURATION
It is possible to change the configuration of the device through the LoRa gateway via downlink frames. You can check if the downlink has been correctly sent because the led will light up blue. The following are the different payloads for the GCM v3 device:

1. Time Update (Little Endian)
   To change the date and time of the device send a 4 byte frame with desired value in UNIX Timestamp on Port 4. Example:

   • Fri Oct 15 2021 06:45:14 GMT+0000
   • 1634280314
   • 6169237A
   • 7A 23 69 61

2. Change transmission windows (Little endian)
   To change the times at which the device sends data send a 2 byte frame with desired value in minutes (UTC Time) on Port 5.
   Example:

   • Sending at 00:00 / 12:00
   • 0 / 720 (Minutes)
   • 0 / 2D0 (Big Endian)
   • 00 00 / D0 02 (Little Endian)

3. Change region
   To change the region in which the device must operate, send 1 byte on Port 6.

   • REGION_AS923 → 00
   • REGION_AU915 → 01
   • REGION_EU868 → 05
   • REGION_KR920 → 06
   • REGION_IN865 → 07
   • REGION_US915 → 08
   • REGION_RU864 → 09

4. Change keys
   To modify ABP or OTAA keys send 1 byte with activation mode 01 or 02 respectively and then 16+16 bytes according to the table on Port 7.

5. Change JoinEUI
   To modify JoinEUI send 8 bytes with the new value on Port 8.

6. Change ACK
   To disable or enable the ACK send by the gateway screen you have to send 1 byte (00 / 01) respectively on Port 9.

7. Test
   To show the downlink message via UART send the ‘x’ bytes on Port 10.

MAINTENANCE

In this section, the maintenance of the device is explained.

CHECKPOINTS
The device needs to be checked periodically by qualified inspectors. These are the check points:

• Measurements Integrity: Be sure that values sent to the platform are between expected values.

• Connections: Be sure that connections between RTUs are in good conditions.

• Clean Sensors: Wipe any dirt present on the MTU sensors with a dry cloth. Make sure the device is not covered with any material.

• Batteries: Check the battery level.
  Some recommendations in order to enjoy a longer useful life of the device:

• Handle device with care, do not allow it to drop or move roughly.

• Avoid placing the devices in areas reaching high temperatures that could damage the electronic components.

• Plug sensor probes only in their corresponding connectors.

• Do not use any type of paint on the device, it could affect the operation of connections and closing mechanisms.

• Do not store Device in places exposed to dirt and dust in order to avoid damage to electronic components.

• For cleaning, use a damp cloth, no aggressive chemical products.

BATTERY CHANGE
To perform the battery change, you need to unscrew 6 corners of the case of MTU.

Then you can replace directly the 3 x AA batteries inside the case with standard AA commercial batteries.
Screw again the case, assuring the correct assembly of all parts and check all the screws are properly tightened. Ensure the rubber seal is located in the plastic channel to prevent damage to it and to maintain the IP rating and protection.

IDENTIFICATION

Each device has a label on the front of the MTU and another on the back. In the back label will be the following fields:

• Model of the MTU.
• Serial Number of the MTU.
• LORA Id.
• Power Supply.
  Besides, the RTU cable is identified with another label with its serial number:
