About the Product:
The LoRaWAN Data Transmission Terminal is a universal communication terminal designed and manufactured around the LoRa RF chip.
It integrates two industrial-standard RS485 interfaces and supports a variety of protocols to realise data transmission between wired and wireless devices.
It supports the LoRaWAN Class C protocol. It can be widely applied to IoT, centralised metering, and industrial control, etc.
LoRa data transmission terminals universal communication interface equipment.
Allows wireless transmission of RS485 data, eliminating the need to run long cables in complex installs.
Includes a pair of communicators (transmitter and receiver).
Note: If more than one LoRa transmitter/receiver set is used on site, they must operate on different communication channels.
IMPORTANT: ALWAYS CONNECT THE ANTENNA BEFORE POWERING UP THE TRANSMITTER OR RECEIVER
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 the RF part
- Supporting LoRaWAN Class C protocol
- Band: 433 Mhz

System Modes
- LoRa Radio – Long Range Radio, and is mainly targeted for M2M and IoT networks. This technology will enable public or multi-tenant networks to connect multiple applications running on the same network.
- LoRa PMAC – Basic LoRa connection example, sending and receiving data. In LoRa–MAC mode, the LoRaWAN layer is bypassed, and the radio is used directly.
- LoRa WAN – Low-power, wide-area networking protocol built on top of the LoRa radio modulation technique.
