[Introduction]：NB1A1 is a series of serial server products independently developed by Ebyte, which can realize two-way transparent transmission of data from 16-channel serial port to Ethernet port. Supports Modbus protocol conversion, multi-host gateway, storage gateway and other data conversion functions. At the same time, it also supports uploading on-site data to the cloud server to realize the cloud monitoring function. The equipment adopts industrial design standards and supports rapid configuration of host computers and AT commands. It is widely used in computer room monitoring, environmental monitoring, intelligent transportation, barrier control, intelligent express cabinets and other industries.
