[Interface signal]：serial port (RS485/RS422/RS232), network port (RJ45)[Size]：198*109*26.5mm[Network protocol]：TCP/UDP/MQTT/HTTP[Installation method]：positioning hole installation[Weight]：518g ± 5g [Introduction]：The serial server series products independently developed by Ebyte integrate the TCP/IP protocol stack, which can realize two-way transparent transmission of data from serial port to Ethernet port,Modbus protocol conversion, serial port device cloud and other functions. The industrial design ensures the stability of the equipment in the harsh working environment,and the rich indicator light effects are used to feedback the different working states of the equipment.
