5.2 Link Mode Applications

5.2.1 TCP Server Application: Enable Virtual COM

SW550xC will encapsulate control packets on top of the real data when Virtual COM is

enabled. This will allow the Virtual COM port in the Windows/Linux system to access

SW550xC’s COM ports. The benefit of using Virtual COM is that rewriting an existing COM

program to read IP packets is unnecessary. In other words, it is possible to use an ordinary

serial (COM) program. The conversion/virtualization of IP to COM is all done in the system

driver transparently. Figure 5.11. shows SW550xC in TCP Server mode with Virtual COM

enabled.

Figure 5.11

 Follow Sec. 5.1.1 to configure SW550xC in TCP Server mode properly.

 Click on the dropdown box of the Application option and switch to “Virtual COM” to

enabled Virtual COM application in SW550xC.

 Scroll to the bottom of the page and click on “Save & Apply” button to save the

changes.

 Configure Virtual COM in the Operating System. For Windows, refer to Chapter 6.

Remember SW550xC’s IP address and the Local Port here in order to enter this

information in Serial/IP Virtual COM’s Control Panel later.
