Ebyte NB124 industrial serial server Four-serial device server RS232/422/485 to Ethernet serial port Modbus gateway IoT module

[Introduction]：NB124 is an industrial-grade 2-way serial port server that supports DC power supply isolation. It integrates the TCP/IP protocol stack inside, which can realize two-way transparent transmission of data from the 2-way serial port to the Ethernet port. The device has the function of ModBus gateway, supports Modbus TCP to RTU, and supports automatic polling. The product adopts industrial-grade standard design to ensure the stability of the equipment in harsh working environments, and the rich indicator lights are used to feedback the different working states of the equipment.
