4.2.1 TCP Server Application: Enable Virtual COM

SW550X 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 SW550X’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. Fig. 4.

11. shows SW550X in TCP Server mode with Virtual COM enabled.

Fig. 4. 11

 Follow Sec. 4.1.1 to configure SW550X 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 SW550X.

 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 5.

Remember SW550X’s IP address and the Local Port here in order to enter this

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