What does serial to Ethernet device server do? How to use it?

In this era of interconnection of all things, the mutual transmission and communication between data and data is particularly important. So how do you connect a computer to a traditional IoT device? At this point, the role of the serial to Ethernet device server medium is highlighted. So, do you know what is serial to Ethernet device server?How to use serial to Ethernet device server? Today, the editor of Hailing Optoelectronics will introduce the serial to Ethernet device server in detail.


A:What is serial to Ethernet device server?

Serial to Ethernet device server, serial to Ethernet server for short.

A serial to Ethernet device server is a networked device used to connect two or more serial devices over a network. It enables you to get rid of the limitations of physical cable lengths and connect serial devices via Ethernet wherever they are located in the world.By using the serial port connection method, the device can work as if it is in close proximity to the device without any intermediate device.

The RS232/485/422 serial port device can be connected into the TCP/IP network to realize bidirectional data transmission between the RS-232/485/422 serial port and the TCP/IP network interface, and the transmission is transparent without any protocol change.According to the number of serial ports, it can be divided into single serial port, two serial ports, four serial ports, eight serial ports and sixteen serial port equipment networking servers.

A:What does serial to Ethernet device server do?

The serial to Ethernet device server instantly connects traditional RS232/422/485 devices to the network. Serial device networking server is like a microcomputer with CPU, real-time operating system and TCP/IP protocol, which transmits data between serial port and network device.Use serial to Ethernet device server to access, manage, and configure remote devices from your computer over a network anywhere in the world.

Electrical equipment with only serial interfaces, such as RTU, CNC machine tools, testers, etc., can be easily connected to Ethernet to achieve network management and remote control.


A:Is serial to Ethernet device server a switch?

No.

The role of the switch is to expand the network signal equipment, which is the Ethernet switch equipment used in industrial control. It is open, widely used, and inexpensive because of the adoption of network standards. It uses the transparent and unified TCP/IP protocol. Network has become the main communication standard in the field of industrial control.

The main purpose of serial to Ethernet device server is to allow serial devices such as printers, scanners, or climate control systems to be used in a network without relying on a computer's serial port for connectivity. This allows any serial device to be connected to the network and accessed from anywhere, including the Internet.

Device connection: First, connect the serial port of the serial to Ethernet device server to the serial port of the device, and connect the RJ45 interface of the serial to Ethernet device server to the router (or directly connect to a PC). Then power up the serial to Ethernet device server.


A:What are the connection methods for serial to Ethernet device server?

Q:Direct connection and Ethernet connection.

The so-called direct connection mode is to directly connect the network port on the serial to Ethernet device server with the network cable port on the computer. The networking mode is simple in wiring and can realize long-distance transmission. Longer distances are possible because of the increased distance from the computer to the serial to Ethernet device server.

The numerical control equipment is connecte to that Ethernet through the serial to Ethernet device server, the wire connection mode is very simple, and only the serial to Ethernet device server needs to be connected to a hub or a switch, By setting the IP address of the serial to Ethernet device server, you can make the serial to Ethernet device server a node on the Ethernet network.The numerical control system connected to the serial to Ethernet device server is connected to the Ethernet, and the RS232/485/422 serial ports of different devices can be connected to the Ethernet through the networking mode to realize heterogeneous networking.


A:How to use serial to Ethernet device server?

Q: Configure serial port parameters:

The serial to Ethernet device server can modify the parameters through the Web page. The serial to Ethernet device server must be in the same subnet as the computer when modifying the parameters through the Web page. Serial port parameters include: baud rate, data bit, stop bit and check bit.

Configure network parameters:

The serial to Ethernet device server 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 (refers to the computer actively looking for the serial port networking server), TCP CLIENT mode (refers to the server actively looking 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.

Enable virtual serial port:

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 placed on the computer. The virtual serial port is responsible for establishing a connection with the serial to Ethernet device server 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.


A:What are the operating modes of the serial to Ethernet device server?

Q: There are four kinds.

1. TCP Server mode.

2. TCP Client mode.

3. UDP mode.

4. HTTPD Client mode


A: Where is the serial to Ethernet device server used?

Q: The serial to Ethernet device server is widely used in access control/attendance, medical applications, remote monitoring, computer room management, and substation management.The serial to Ethernet device server can support the virtual serial port protocol, so that you do not need to change the original PC software, provide the transparent data conversion function between the serial port and the Ethernet port, and support DHCP and DNS. It is a full-duplex serial to Ethernet device server without packet loss.

RS232/485/422 three-in-one serial port, RS232, RS485, RS485/422, RS232/485 and other serial port combinations. In addition, there is serial to Ethernet device server with multiple serial ports and secondary development, which can meet all-round applications.


A: Give three common examples.

Q: 1. Unattended weighing: The serial to Ethernet device server can be used to connect weighing instruments, receipt printers, gates and other weighing supporting equipment into the LAN. A LAN computer can be used to complete centralized control and data statistics management. The control center can remotely control the gate switch through the Ethernet.

2. Intelligent agriculture: through the serial to Ethernet device server to connect the temperature and humidity instrument, it can realize the on-site environmental monitoring management and realize the artificial intelligence management.

3. Intelligent transportation: serial to Ethernet device server is connected to the signal lamp, and the control center realizes the collection and processing of on-site traffic data through Ethernet. At the same time, it can also provide accurate quantitative basis for traffic command and dispatch and urban traffic planning. Traffic congestion, traffic time, traffic accidents, traffic capacity and other traffic phenomena are optimized in real time from a regional or global perspective.


A: How is serial to Ethernet device server applied?

Q: 1.For the serial to Ethernet device server, the serial port RS232/485 is usually connected to the serial device, and the other end is connected to the network port. The RS232 and RS485 serial ports work independently at the same time and do not affect each other.

2.Modbus TCP/RTU bidirectional conversion and configuration software interface.
