[Introduction]：The NB183S-V2 is a second-generation 8-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. This serial 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.
