Applications 

 
 

5.2 

Link Mode Applications 

 

This section describes application options for the TCP Server, TCP Client, and UDP

 

Link Modes

.

 The application 

options will define how the serial data communication will be emulated over the network communication link

. 

The 

user will have flexibility in choosing the suitable application that matches their need for serial data communication

.  

 

 
 

5.2.1 

TCP Server Application: Enable VirtualCOM 

SW550X will encapsulate control packets on top of the real data when Virtual COM is enabled

. 

This will allow the 

Virtual COM port on the Windows

/

Linux operating 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 or legacy serial 

(

COM

) 

program

. 

The conversion

/

virtualization of IP to COM is all done 

in the system driver transparently

. 

Figure below shows SW550X in TCP Server mode with Virtual COM enabled

.

 

Please follow the following steps to enable Virtual COM application in TCP Server Link Mode

.
