LoRaWAN Gateway Structure and Interface Definition           The gateway peripheral interface is described as follows:

LoRaWAN Gateway Installation and startup :
» Gateway Installation:
Operating instructions for installing and fixing the installation kit to the gateway shell and bearing rod:

1. Fixthe equipment support at the bottom of the cabinet with four M6 * 12 screws according to the direction shown in the figure below.
2. Tighten the pole clamping rod with bolts, washers and nuts. Note: the diameter of the pole supported by the support is 50mm to 100mm. If the pole diameter is greater than this value, steel strip can be used. There is no standard delivery of steel belt, and users can purchase it separately.
3. Hang the equipment and fix it with two M6 * 12 screws.

» Gateway interface protection:
Tape sealed antenna and cable connections:

1. Clean the surface of the area to be wrapped, wrap a layer of PVC tape with 50% overlap according to the rotation direction of the joint, and the winding length is about 10mm beyond the tail of the joint.
2. Wind three layers with natural uncoiling force and 50% overlap rate. The head and tail ends are required to be covered with 10mm waterproof tape, and the tail is cut with scissors.

» Gateway startup
Installing antenna
The first step is to screw the antenna onto the antenna connector of the gateway panel and the LoRa antenna onto the antenna interface of the corresponding silk screen LoRa1. Gateway power on
It is recommended to use CAT5 cable and PoE power adapter to power the gateway equipment. The gateway is equipped with PoE power adapter as standard.
a.Unscrew the PoE interface of the gateway device.
b.Connect one end of the network cable to the “PoE” interface of the PoE power adapter and the other end to the PoE interface of the gateway device.
c.Connect the PoE power adapter to the power supply, and the gateway will be powered on successfully. » Gateway access to external network
There are two ways of gateway data return link:

1. Ethernet mode. Connect a network cable to the “LAN” interface of the PoE power adapter, connect the other end to the router, and then connect the gateway to the power supply. Power on and use it.
2. 4G LTE mode. Insert the 4G SIM card, then connect the gateway to the power supply, and turn it on for use.
   After power on, wait for 3 to 5 minutes, and test after the gateway is powered on and connected to the external network.

Note: when any antenna portis open, the gateway equipment cannot be powered on. If one or more antenna ports do not need to be used, make sure to connecta 50 Ohm load to the port.
Indicator light
The status of LED indicator is described as follows:

Off: network disconnected
Flashing: data transmission receiving
LED3(LoRa1)| Always on: LoRa1 works normally
Off: LoRa1 work interruption / abnormality
Flashing: LoRa1 packet receiving and sending
LED4(WLAN)| Reserve
LED5(LTE)| Slow blinking (1800ms high / 200ms low): network search
Slow flashing (200ms high / 1800ms low): idle
Fast blinking (125ms high / 125ms low): data transmission in progress
Always on : voice is working

Fault handling mode

1. When using 4G card LTE mode, if the light status lasts for 5 minutes and flashes slowly, please pay attention to whether the frequency band supported by the 4G card meets the frequency band supported by the 4G module. Ifitis confirmed that it meets the requirements, please contact our company to debug the gateway.
2. After the gateway is powered on, check the network status according to the indicator light. After waiting for 5 minutes, the network has not been obtained. Please confirm the network interface or SIM card. If the network is confirmed to be normal, power off and restart (unplug the power, wait for about 1 minute until the indicator light is off, and then connect the power).
