[Introduction]：The NA281 is a DIN rail-mounted multi-serial port server series independently developed by EBYTE. It integrates a TCP/IP protocol stack, enabling bidirectional transparent data transmission from serial to Ethernet ports, Modbus protocol conversion, and serial device cloud connectivity. Its industrial design ensures stability in harsh working environments, and rich indicator lights provide feedback on different operating states. It supports host computer, AT command, and web page configuration, allowing for easy networking and cloud connectivity of serial devices with simple configuration. It is widely used in industries such as data center monitoring, environmental monitoring, intelligent transportation, gate control, and smart parcel lockers. The product is coated with a conformal coating, providing anti-mildew, anti-moisture, and anti-salt spray properties.
