What is serial to Ethernet converter?
Serial to Ethernet converter: serial to Ethernet converter can make your serial device connect to the internet, which can provide serial to Ethernet function. Serial to Ethernet converter can change the RS232/485/422 serial port into TCP/IP interface, thus to realize the transparent data transmission between RS232/485/422 and TCP/IP network interface. Serial to Ethernet converter can make the serial device with TCP/IP network interface function, thus to realize the data transmission and expand the communication distance.
How to use serial to Ethernet converter?
The following describes how to use the serial to Ethernet converter to connect the serial port device to the computer through the network:
Connect the devices
First, connect the serial port of the serial to Ethernet converter to the serial port of the device, connect the RJ45 interface of the serial to Ethernet converter to the router (or connect to the PC directly), and then power on the serial to Ethernet converter.
Configure the parameters of the serial port
People can modify the parameters of the serial to Ethernet converter through the Web page. When modifying the parameters through the Web pages, the serial to Ethernet converter must be in the same subnet as the computer. The parameters of the serial port include baud rate, data bit, stop bit, and check bit.
The work mode of serial to Ethernet converter
The serial to Ethernet converter must have an IP that can be configured statically or obtained through the DHCP server. The working mode of serial to Ethernet converter includes:
TCP Server mode: TCP Server mode refers to the computer actively looking for serial to Ethernet converter.
TCP client mode: TCP client mode refers to the serial to Ethernet converter actively looking for the computer.
And UDP mode:
The purpose of configuring the network parameters is to enable the computer to establish a smooth connection to the networked server.
Virtual serial ports
Because of the PC software usually operates the serial port and device communication. But the parameters of the network are changed, there must be a virtual serial port needed on the computer. The virtual serial port is responsible for establishing a connection with the serial to Ethernet converter and sends the data to the user’s program.
What applications does the serial to Ethernet converter used in?
Serial to Ethernet converter is widely used in access control/attendance, medical applications, remote monitoring, computer room management and substation management. Serial to Ethernet converter can support the virtual serial port protocol, so that you do not need to change the original PC software, provide transparent data conversion between serial port and Ethernet port, support DHCP and DNS. full duplex, no packet loss.
USRIOT produce Rs232/485/422 three-in-one serial port , RS232, RS485, RS485/422, RS232/485 serial to Ethernet converters. Besides, there are multiple serial ports or subsequent development of serial to Ethernet converters that can meet the full range of applications.
