workload required on it. Do not connect the power cable while the power is on. A sudden rush of power can damage sensitive electronic components. Only experienced electricians should open the chassis.
| ****

Always ground yourself to remove any static electric charge before touching DEBIX product. Modern electronic devices are very sensitive to electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag.

Safety Instruction
To avoid malfunction or damage to this product please observe the following:

1. Disconnect the device from the DC power supply before cleaning. Use a damp cloth. Do not use liquid detergents or spray-on detergents.
2. Keep the device away from moisture.
3. During installation, set the device down on a reliable surface. Drops and bumps will lead to damage.
4. Before connecting the power supply, ensure that the voltage is in the required range, and the way of wiring is correct.
5. Carefully put the power cable in place to avoid stepping on it.
6. If the device is not used for a long time, power it off to avoid damage caused by sudden 4  overvoltage.
7. Do not pour liquid into the venting holes of the enclosure, as this could cause fire or electric shock.
8. For safety reasons, the device can only be disassembled by professional personnel.
9. If one of the following situations occur, get the equipment checked by service personnel:
   • The power cord or plug is damaged.
   • Liquid has penetrated into the equipment.
   • The equipment has been exposed to moisture.
   • The equipment does not work well, or you cannot get it to work according to the user’s manual.
   • The equipment has been dropped and damaged.
   • The equipment has obvious signs of breakage.
10. Do not place the device outside the specified ambient temperature range. This will damage the machine. It needs to be kept in an environment at controlled temperature.
11. Due to the sensitive nature of the equipment, it must be stored in a restricted access location, only accessible by qualified engineer.

Chapter 3 Getting started

Hardware connection

Component Preparation

• DEBIX LoRa board, DEBIX motherboard
• LoRa Module
• 2 x External Antenna

The connection steps are as follows:

1.  Install the LoRa module onto the DEBIX LoRa board, as shown below:

2.  Connect two antennas to the antenna interfaces of the DEBIX LoRa board, as shown in the following figure:
   

3. . Align the female header of DEBIX LoRa board with the top pin header of DEBIX motherboard, and press to insert, as shown in the following figure:
   NOTE
   It is necessary to confirm that the female header of DEBIX LoRa board are aligned one by one with the top pin header on the DEBIX motherboard to avoid damage to the board caused by power on after misalignment.

4. Insert the Micro SD card with DEBIX system into the slot of DEBIX motherboard, connect DEBIX peripherals (HDMI monitor, keyboard, mouse, network cable), power up DEBIX, and the DEBIX can be used normally.

Chapter 4 Function Examples

Usage of LoRa module

• Component Preparation
  • DEBIX LoRa board, DEBIX motherboard
  • WiFi antenna, LoRa antenna, LoRa module
  • Peripherals (HDMI, keyboard, mouse, network cable)
• LoRa module hardware resources:

Table 6 LoRa module hardware resources

1. Connect DEBIX LoRa board and DEBIX motherboard as the steps described above, and power up DEBIX;
2.  Ubuntu Desktop Setting:
   • Enter the DEBIX system desktop, select Add-on Board APP, and switch to the corresponding device tree;

• * In the pop-up “DEBIX add on board dtb file selection” window, select Debix board and click OK.

  • Select None for Panel and click OK.
  • Reboot the device to take effect the above settings.

Check whether LoRa is supported in the system:

Open the terminal, run the command ls /dev/lora*, the output is as follows: /dev/lora_en /dev/lora_reset

• The existence of lora_en and lora_reset files in the /dev/ directory proves that the DEBIX kernel supports LoRa.

Test whether the LoRa module is normal:

• Run the command cd /opt/packet_forwarder/, and sudo ./lora_pkt_fwd, the output is as follows:
• Packet Forwarder
• Version: 1.0.5
• SX1302 HAL library version info
• Version: 1.0.5;
• INFO: Little endian host
• INFO: found configuration file global_conf.json, parsing it
• INFO: global_conf.json does contain a JSON object named SX130x_conf, parsing
• SX1302 parameters
• INFO: spidev_path /dev/spidev0.0, lorawan_public 1, clksrc 0, full_duplex 0
• lgw_board_setconf:236: Note: board configuration: spidev_path: /dev/spidev0.0,
• lorawan_public:1, clksrc:0, full_duplex:0
• INFO: antenna_gain 0 dBi
• Note: success connecting the concentrator
• Loading AGC fw for sx1250
• Loading ARB fw
• INFO: [main] concentrator started, packet can now be received
• INFO: concentrator EUI: 0x0016c001ff1a8f79
