CIR372-D is an IoT cellular router that integrates 4G LTE, Wi-Fi, GPS and VPN technologies to provide an easy, reliable, secure Internet connectivity and high-speed data access for equipment networking. With technologies such as 4G wireless wide area network, dual Ethernet ports (LAN + WAN), Wi-Fi wireless local area network it provides uninterrupted multiple network access capabilities.
CIR372-D can offer a choice of (3-wire) RS485. This means that RS485 devices, such as electricity meters, programmable logic controllers including Modbus RTU equipment can connect to the internet directly through the router. With the GPS function, users can monitor their asset remotely, and can monitor the trajectory of the vehicle.
The product adopts high-performance CPU, working frequency up to 580MHz, based on a variety of hardware interfaces and powerful software functions, users can quickly build their own application network. It is suitable for large-scale distributed industrial applications, such as smart express cabinets, charging piles, CCTV, ATM machines, ticket machines, traffic management, vending machines, medical device networking, tower monitoring, lifts monitoring, digital signage, electricity, water conservancy, environmental protection, etc.
