[Introduction]：NB183E-V2 is Ebyte's second-generation 8-channel serial port server. It integrates a TCP/IP protocol stack, enabling two-way transparent transmission of serial-to-Ethernet data, Modbus protocol conversion, and serial device cloud connectivity. This serial port server supports host computer configuration and is widely used in industries such as computer room monitoring, environmental monitoring, intelligent transportation, gate control, and smart express lockers. It is coated with conformal coating for mildew resistance, moisture resistance, and salt spray resistance.
