LoRa wired Ethernet terminal | gateway
ZW-LRT101 is a LoRa gateway for wired Ethernet, supporting TCP/UDP and TDMA networking.
The LRT101 LoRa Ethernet gateway manages the communication of LoRa terminals in this area, and connects the LoRa terminal data in this area to the server through Ethernet TCP or UDP. ZW-NR200 provides RS232 and RS485 interfaces, which can directly connect to serial devices and achieve data transparent transmission; It can achieve functions such as digital input and output, pulse output, analog input, pulse counting, etc.
This product is widely used in the M2M industry in the IoT industry chain, such as remote meter reading, smart cities, smart factories, smart buildings, smart firefighting, smart parking, smart homes, industrial control wireless transmission, and other fields.
