Serial to ethernet converters are widely applied in engineering control sector, and yet there are also various problems in practical application.
Here are some common problems in the application of serial to ethernet converters and the resolutions as follows.
Q: How to configurate serial to ethernet converters?
A: Serial to ethernet converters must be configurated in the light of actual application. The parameters to be configurated include working pattern of serial, network parameters, management information of devices, etc. Generally, serial to ethernet converters can be configurated through multiple configuration methods, such as serial, browser website, supervisor, etc.
Q: When multiple serial to ethernet converters work as TCP Client to connect servers through public network, there will be only one open IP port on server end. How to connect?
A: The upper computer set virtual serial port to be server end and send corresponding commends to slave unit through calling serial with serial assistant. As long as the ID of device is corresponding, the slave unit will make response.
Q: Why will there be data lost when transferring document with virtual serial port?
A: The loss of data is mainly ascribed to the inconsistence of serial transmission speed of sending data to distance device when virtual serial program puts an end to data. The problem can be solved by setting “simulated baud rate” in virtual program.
Q: Can multiple computers access the same serial to ethernet converter?
A: Multiple computers can access at the same time. Under the state of polling, only one computer can connect the serial to ethernet converter. In addition, it can accomplish automatic polling with no need to set other parameters.
Q: How to set serial and baud rate of serial to ethernet converters?
A: Click into “plan configuration” in the interface of configuration, and then click into “serial parameter” after selecting plan.
