[Introduction]：NB124E is a 2-way serial port server that supports POE power supply. 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 light effects are used to feedback the different working states of the equipment.
