EBYTE NB144ES 4-Channel Serial Server RS232/422/485 RJ45 Modbus Gateway POE Receiving Power TCP/UDP/MQTT DC 8-28V
NB144ES serial device server modbus communication module RS485 to TCP/IP gateway RJ45 network port [Interface signal]：RS485/RS422/RS232 [Baud rate]： 2400~115200bps (default 115200) [Product size]：198x109x26.5mm (LxWxH) [Installation method]： positioning hole installation [Product weight]：530g±5g [Introduction]：NB144ES is an industrial-grade 4-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 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.
