[Introduction]：NB144E is a 4-way serial port server that supports POE power supply. It integrates the TCP/IP protocol stack inside and can realize two-way transparent transmission of data from the 4-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.
