Category : how to

If you communicate with existing serial device through RS232/RS422/RS485, you can do it.
But, it could be slight alterability in accordance with your system's organization including ezTCP.
Please, refer to the next writing.


1:1 communication


Organize system like below.



In this situation, one ezTCP set up Server(T2S) mode and the other set up Client(COD) mode
The ezVSP supplied free of charge by Sollae Systems is alternative to ezTCP on PC side.
* Refers to the next writing for more information of ezVSP.
ezVSP introduction page
Here is one of the best ways to apply ezTCP.
If any existing software(or program) on PC is replaced with software which support TCP/IP protocol,
then the user don't need ezVSP or the ezTCP on PC side any more.



1:N communication



As it is said above(1:1 communication), the software on PC need to be replaced with
the software which support TCP/IP protocol for 1:N communication like above image.
* Here are two of the ways.
- View 1:N communication by TCP
- View 1:N communication by UDP broadcast

N:1 communication



In this case like above, ezTCP should operate Client(COD) mode(if TCP use) or UDP(U2S) mode(if UDP use).
Of course, the software on PC is replaced with suitable one.
