The origin of Serial to ethernet converter

 

The keywords of serial to Ethernet converter are serial port and Ethernet. Generally, the network can be divided into the outer net and inner net. At present, the inner net refers to Ethernet, the outer net refers to the Internet, the Internet is an effective way of communications globally.

Before the popularity of the network, generally the RS232 port can the transmit the data between the device and the computer, If it is required a long-distance transmission, RS485 can be adopted, the longest transmission distance of RS482 can over 1000 meters.

 

With the development of network and modern information technology, several requirements for serial to ethernet converter are gradually presented:

 

1.Some applications need to monitor the devices which distributed around the world remotely.

 

2.Such as computer room monitoring, self-service banking system communication, office building automatic control system and other applications, these system has a complete network wiring, can we use these network facilities to realize equipment communication is a question

 

3.For RS232 port, a PC serial port can only connect one serial port device. If multiple devices need to be connected, the original serial port scheme will not be easy to expand, but the network does not have this problem.

 

For these reasons, the device needs to be connected to the network. However, there are already thousands of original serial devices, which cannot be transformed overnight. Therefore, as a temporary solution, serial to Ethernet converter, which is converted from serial port to network port, has existed.
