Overview
The LoRa-A4/A9 is a cost-effective Industrial IoT gateway that integrates LoRa wireless communication and an RS-485 wired interface.
It supports bidirectional data transmission between LoRa and RS-485 devices, effectively solving the interoperability challenges between devices using different communication protocols.
It is widely used in remote data acquisition, equipment monitoring, and intelligent control systems.
Notice:
Model difference:
LoRa-A4 Gateway: Frequency band 410.125~493.125MHz
LoRa-A9 gateway: frequency band 850.125MHz-929.125MHz
The only difference is the frequency band, the rest are the same! ! ! !
This manual takes the LORA-A4 gateway as an example. All the following frequency bands are based on the LORA-A4 gateway.
