There are several ways to send the file to the Show Touch.
Using the Controller (V16Pro, V4Pro, VCore)
One way is to from the "File" menu in Touch. Select "Save to Remote Server" with your touch file open on your PC. Then, go to the ShowTouch control panel interface and "open" the file from the remote controller.
FTP File Directly
Alternatively, you can FTP the file directly to the show touch using the settings here:
Using the CF Card
This is the least preferred method, but can be used if necessary. You can remove the CF card from the ShowTouch and copy the files directly using your PC card reader.
