[Introduction]:NB144S is a 4-way serial port server which supports POE power supply. It integrates TCP/IP protocol stack inside and can realize two-way transparent data transmission from 4-way serial port to Ethernet port . The device has ModBus gateway function, supports Modbus TCP to RTU, and supports auto polling. The product adopts an industrial-grade standard design to ensure the stability of the equipment in harsh working environments, and the rich luminous effects are used to signal the different working states of the equipment.
