NA241 Isolated 4-way serial server dual Ethernet port design with switch

[Interface signal]: RS485

[Operating voltage]:DC 8~28V

[Size]:40*111*119.4mm

[Introduction]:NA241 is a series of rail-type multi-serial server products independently developed by Ebyte. It integrates the TCP/IP protocol stack and can realize two-way transparent transmission of data from the serial port to the Ethernet port, Modbus protocol conversion, and cloud access for serial devices. The industrial design ensures the stability of the equipment in harsh working environments, and the rich indicator light effects are used to feedback the different working conditions of the equipment. Supports host computer, AT commands, and web page configuration. With simple configuration, you can easily realize networking, cloud and other functions of serial device. It is widely used in computer room monitoring, environmental monitoring, intelligent transportation, gate control, intelligent express cabinets and other industries. The product is sprayed with conformal anti-paint, which has the functions of "anti-mold", "anti-moisture" and "anti-salt spray".
