The LoRaWAN Data Transmission Terminal is a universal communication interactive equipment that is designed and manufactured based on LoRa RF chip.
It integrates two interfaces of industrial standard RS485 and supports a variety of protocols to realize the data transmission between wired and wireless devices.
It supports LoRaWAN Class C protocol. It can be widely applied in the IoT, centralized metering and industrial control, etc.
Key features:
Small, easy to install
Operating temperature range: -20 to 70 oC
1 standard interface of RS485, supporting a variety of protocols and communicating with various automatic devices with RS485 interfaces
Equipped LoRa chips SX1276 from Semtech for RF part
Supporting LoRaWAN Class C protocol
Band: 433 Mhz
Wireless ultra-long transmission range with up to 6-8 km barrier-free
1.9-meter Antenna lead with magnetic base Antenna 413-453 MHZ
Mostly used in metering projects where cabling is expensive or not possible. This module helps integrate remote Modbus meters and IO modules without the need for long cable runs.
Communication:
Interface RS485 half-duplex
Protocols: MODBUS RTU, DL/T 645
Baud rate: 1200, 2400, 4800 or 9600 bps, 8N1, 8E1 or 8O1
Packet Length Sent 255 bytes

Thank you very for this video.
How is the connection done on the fuse board?

[@user-so2zp9kc8t]

Can you tell me the function of the RUN led please?
