2. Mini Indoor Gateway Introduction
2.1 Appearance
The gateway features a streamlined pebble-and-water-drop design with a glossy pure-white shell. Its rounded, smooth curves have no sharp edges, and the device is slim, light, and compact. The front of the device is an integrated smooth shell with a small status indicator opening at the top-left corner and no extra buttons, giving it a minimalist look that suits a wide range of small industrial and office environments. The rear of the device features an integrated recessed interface slot that neatly houses the power jack, network port, and buttons, so cables do not protrude after being plugged in, preserving the device's sleek profile.
The device supports two installation methods — flat placement on a desktop and wall mounting — making it suitable for weak-current boxes, walls, desktops, and other locations.
2.2 Interface Description
The interfaces on the rear of the device are arranged from left to right. The functions of each interface and button are described below:
| No. | Interface / Button | Description |
|---|---|---|
| (1) | DC Power Jack | The main power input of the device, matching the DC power adapter included in the package. Input specification: 12 V/2 A. It provides the primary power for stable device operation. |
| (2) | RJ45 Ethernet Port | A standard wired network interface that connects to a router or a switch via an Ethernet cable for LAN and cloud data transmission. The port has a built-in dual-color status LED: a solid green light indicates a normal physical cable connection, and a flashing yellow light indicates that the device is sending and receiving network data. |
| (3) | Reset Pinhole | The system reset button of the device. Press and hold it with a slender object such as a toothpick or a pin, and release after 5 seconds. The device will be restored to factory settings, and all network and device configurations will be cleared. |
| (4) | Type-C Port | It has dual functions: auxiliary power supply — a phone Type-C charging cable can be used to temporarily power the gateway; and a debug serial port — when connected to a computer, it allows reading device operation logs and debugging local device parameters. |
2.3 Status Indicator
The front of the device has a three-color status indicator (red / green / blue). Each color reports one aspect of the gateway's operation:
(1) Red — System Power and Basic Operation
| State | Meaning |
|---|---|
| Solid | The device is powered on and running normally. |
| Off | The device is not powered, or a power fault has occurred. |
| Blinking slowly | The system is booting up or a factory reset is in progress. |
| Blinking fast | The system has encountered a fault or critical error. |
(2) Green — IP Network Connection
| State | Meaning |
|---|---|
| Solid | An IP address has been obtained and the network connection is up. |
| Off | The network is not connected or not enabled. |
| Blinking | The gateway is trying to connect to the network (Wi-Fi / Ethernet searching or dialing). |
(3) Blue — LoRaWAN Service
| State | Meaning |
|---|---|
| Solid | The LoRaWAN Packet Forwarder is running normally and connected to the LoRaWAN network server. |
| Off | The LoRaWAN module is not started, or no network server is configured. |
| Blinking | LoRa packets are being received or sent (RF activity). |
3. Hardware Installation and Wiring
3.1 Power Supply Options
The device supports two power supply methods. The DC power adapter is the preferred method; Type-C is only for temporary backup power.
- Primary power: Plug the included power adapter into the DC jack on the rear of the device, and plug the adapter into a wall outlet.
