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

Product Descriptions

NB124 is a 2-way serial port server. It integrates the TCP/IP protocol stack inside, which can realize data transparent transmission 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.
