What is a Serial to Ethernet server

  This Serial to Ethernet server, to put it bluntly, is a transit station that provides passive data transmission, and through its own connectability, it can connect to the Web server and serial port of the computer at the same time.

  Help the serial port and the network to form an interactive link, and implement the two-way transparent data transmission effect of data.

  The communication between the serial port and the server makes it possible to communicate in large area and long distance.

  Serial to Ethernet server connects the computer server with serial devices, so that the computer server can be used to control serial devices.

  Serial to Ethernet server role:

  ① Serial to Ethernet server is able to connect the computer port and other embedded computer devices, and record the specific model data information of the port device.

  ② Serial to Ethernet server needs to use the specified server port for connection, and extend at the port of this model.

  The Serial to Ethernet server implements the task of transmitting data communication, and transmits data back and forth through the Serial to Ethernet server.

  And (3) the server port and the serial port of the device are mutually connected, so that the computer can remotely control the serial port device, thereby enabling the serial port device to be more efficient and rapid, improve the utilization rate, have reasonable space and save resources.

  The signal is directly converted into the Ethernet format, so that the data can be directly transmitted to the serial port background server, thereby facilitating the transmission efficiency and unification of the data.

  Summary: The use of Serial to Ethernet server has played a vital role in the data transmission between the serial port and the computer server.

Advantages of Serial to Ethernet server networking

The main advantages of using PUSR Serial to Ethernet server are:

1. Upgrade access: remote connection of serial devices;

2. Cost saving: no need to change the existing software to communicate with the serial device;

3. Seamless communication: Serial to Ethernet connections are transparent to both the device and the software;

4. Make full use of the existing equipment: start the com port with Ethernet;

5. Protect the functional original network: connect the serial network into one or more subnets of the LAN;

6. Manpower saving: remote access to serial devices;

7. Save time: Update serial device software faster and easier over Ethernet.

If the Serial to Ethernet server is garbled, there are usually two reasons:

1. The baud rate, data bit, and check bit of the Serial to Ethernet server do not match, that is, the baud rate of our network to serial port device does not match that of your serial port device. Set them to be consistent.

2. Due to hardware reasons, note that the TTL, RS232, and RS485 levels in the Serial to Ethernet server and the Serial to Ethernet module are different and cannot be directly connected. They need to be forwarded by an RS232 chip or an RS485 chip. One of the most common mistakes made by customers is to connect the TTL level directly to the computer, which is bound to be garbled. The computer is RS232 level. In addition, improper hardware design and interference may also lead to abnormal communication. Check the hardware carefully.

If you can't confirm where the problem is, you can use the form of self-sending and receiving to eliminate it.

1. Your serial port networking device directly communicates with the computer. Check whether it is normal according to the baud rate settings you understand, so as to confirm whether there is any problem with your serial port networking device settings.

2. Disconnect the connection between your device and the Serial to Ethernet server, and then short-circuit the RXD and TXD of the serial port of our Serial to Ethernet serverttl, and send and receive data through the network to see if the data is normal. To confirm that our Serial to Ethernet server is working properly.

3. Disconnect your device from the Serial to Ethernet server, and then short circuit the serial port of your device. Check whether the data is normal through the computer to confirm that the hardware from your computer to the serial port works normally.
