DataHub supports multiple communication methods and hardware interfaces, including 3G/4G/5G high-speed networks, Wi-Fi wireless communication, and 10M/100M/1000M adaptive Ethernet communication. It features multiple opto-isolated RS-485 ports, an opto-isolated CAN bus interface, a USB interface, and a high-capacity TF card slot. Equipped with a real-time clock function and built-in supercapacitors, it enables power-off detection and ensures the preservation of critical data. The unit also supports online upgrades for both underlying firmware and applications. Its key features include high availability, power-off resumable transmission, and modular-level redundancy.
