SZ11-GW-3 JuHe Gateway

SZ11-GW-3 JuHe Gateway

First, product introduction

 

The SZ11-GW-3 Gathering Gateway is an IoT wireless communication gateway that uses the public network wireless network + small wireless network to provide users with the function of eliminating field wiring and wireless long-distance data transmission.

The product uses a high-performance industrial-grade 32-bit processor and an industrial-grade wireless communication module. It also provides one serial port (RS232/RS485), four Ethernet LAN ports, one Ethernet WAN port, and supports WIFI as an AP. /Repeater/STA, so you can connect serial devices, Ethernet devices and WIFI devices at the same time, which is a perfect platform for IoT applications. It can be widely used in self-service terminal industry, smart grid, intelligent transportation, supply chain automation, industry. Automation, intelligent building, fire protection, environmental protection, smart medical, intelligent lighting, intelligent agriculture and coal, oil and other occasions.
