1. Introduction
IoT refers to the connection of wireless and wired-based sensing systems to the Internet and
the web. Through this, the value of sensing data is maximized by facilitating the use of sensing
data.
LoRa Gateway is located between the Node and the Network Server system and converts the
sensing data provided by the Node into a Network Server compatible format and transmits the
commands sent from the Network Server to the Node. Usually, a Linux router with wired
(Ethernet) and wireless (Bluetooth, LoRa, ZigBee, etc.) communication interfaces based on
processors such as ARM Cortex-A series and MIPS.
PLG400 is a LoRaWAN gateway that can be installed outdoors. LoRaWAN is a low power wide
area (LPWA) wireless network technology widely used in the Internet of Things, and the
PLG400 connects various installed LoRa sensors to the Internet.

4. Quick Start
The PLG400 is set up to connect to the WAN using DHCP. Therefore, a PoE injector can be used
to connect a LAN for the Internet connection to the WAN and connect the power. When the power
is connected, the PWR, WAN inside the device turn on.

5. Preferences
5.1 Connection & Login
To change various settings of the PLG400, you need to access the built-in web interface.
•Access the assigned IP through the WAN port of the gateway. If you are using a static IP or
know the IP address assigned through a DHCP server, you can use that IP address to connect.
•Enter port 8080 after the IP address to connect. Ex) http: // [IP address]: 8080
When connected, the login screen will appear as shown below.
D and Password to input are as follows.
ID

7. Troubleshooting
⚫The PWR LED does not light up.
→Make sure the 48V PoE adapter provided with the gateway is physically connected
→After removing the adapter, apply power again after a full discharge (approximately 20
to 30 seconds).
⚫LoRa LED does not light up.
→Check that the gateway is registered in the network server as a compatible device.
→After pressing the reset switch, check if it operates normally.
⚫The WAN LED does not light up.
→LAN Check if the LAN cable is properly connected to the WAN port.
→Check that the gateway is registered in the network server as a compatible device.
