Without seeing your code? Without knowing what the problems are? Without knowing what a "foca" connection is? No.

In fact, I can not uplaod sketches from arduino IDE.
I have error getsync() !
It means that the foca (usb to serial converter) is not recognized by pc or something like this.
Thus, I want help with how to connect pins between foca and arduino ethernet board.

You STILL have not posted a link that tells us what a “foca” is.
