Description
Overview
GAOTek Edge Computing Gateway With USB Support Digital is an IoT wireless intelligent gateway that provides users with wireless long-distance big data transmission using a public 3G or 4G network. The product uses a high-performance industrial-grade 32-bit communication processor and industrial-grade wireless modules, with an embedded real-time operating system as a software support platform, and provides one RS232, five RS485, four Ethernet LANs, and one Ethernet. WAN and WIFI interfaces can connect serial devices, Ethernet devices and WIFI devices at the same time. The intelligent gateway can be connected to multiple manufacturers’ IoT platform SCADA systems. It can connect intelligent devices such as smart meters and PLCs through RS232 or RS485 or Ethernet ports. Its main function is to process uplink and downlink information and complete the forwarding and passing of different protocols. The MQTT way connects to the Internet of things platform.
