1. Ethernet to RS485 converter can connect traditional RS232/422/485 devices.
Ethernet to RS485 converter is like a microcomputer with CPU, real-time operating system and TCP/IP protocol, which transmits data in serial and network devices. The Ethernet to RS485 converter allows you to access, manage, and configure remote devices from anywhere in the world through your computer.
The microcomputer protection device can be easily connected to the Ethernet to realize networking management and remote control for the electrical equipment which is only connected in series, such as POS, ATM, display screen, keyboard, card reader, card reader, switch, computer, refueling machine, RTU, CNC machine tool, test instrument, etc.
2. Ethernet to RS485 converter allows you to reduce the workload.
First, the high-quality Ethernet to RS485 converter will have a "friendly management interface". These numerous serial devices may be scattered in different remote locations. Therefore, it is an important indicator that the high-quality serial converter can complete all the settings with a single interface, whether it is Windows software. Web or Telnet.Performance and low latency. In some traditional serial transmission applications, 115.2Kbps is enough. However, if you want to switch to 100m switch communication, the speed of 230.4Kbps of the embedded equipment module will be more guaranteed.
First, connect the serial port of the Ethernet to RS485 converter to the serial port of the device, and connect the RJ45 interface of the Ethernet to RS485 converter to the LTE 4G router (or directly connect to a PC). Then power up the Ethernet to RS485 converter.
The parameters of Ethernet to RS485 converter can be modified through Web page. The Ethernet to RS485 converter must be in the same subnet as the computer when the parameters are modified through the Web page. Serial port parameters include: baud rate, data bit, stop bit and check bit.
The Ethernet to RS485 converter must have an IP, which can be configured as static or obtained through a DHCP server. Configure the working mode of the serial port networking server, including TCP SERVER mode (the computer actively searches for the serial port networking server), TCP CLIENT mode (the Ethernet to RS485 converter actively searches for the computer), and UDP mode. The purpose of configuring the network parameters is to enable the computer to establish a connection with the networked server smoothly.
Because the PC software of the general user still opens the serial port to communicate with the device, at this time, because the network is used, a virtual serial port must be installed on the computer. The virtual serial port is responsible for establishing a connection with the Ethernet to RS485 converter and forwarding the data to the user program that opens the virtual serial port. Run the user equipment communication program and open the virtual serial port. The user application can then communicate with the device.
