[Introduction]：The NB144E-V2 is a second-generation 4-port serial server developed by Ebyte. It integrates a TCP/IP protocol stack, enabling bidirectional transparent transmission of serial-to-Ethernet data, Modbus protocol conversion, and serial device cloud connectivity. Supporting host computer configuration, it is widely used in industries such as computer room monitoring and environmental monitoring. It is coated with conformal coating, offering anti-mold, anti-humidity, and anti-salt spray properties.
