[Introduction]：The NB124-V2 is a second-generation, dual-port serial server developed by Ebyte. It integrates a TCP/IP protocol stack and enables bidirectional, transparent serial-to-Ethernet data transmission, Modbus protocol conversion, and serial device cloud connectivity. It supports host computer configuration, enabling easy networking and cloud connectivity for serial devices with simple configuration. It 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.
