# Set up handshaking for a String Input Enable button

When the operator presses the Enter button, the pop-up writes a value to the data source. Use Enter key handshaking to hold the value at the data source for a specific period of time to ensure it is read before the operator sends a new value to the Value connection.

Tip: | For these settings to take effect, you must assign connections to Enter and Enter handshake in the Connections tab.

## To set up handshaking for the button

1. In the Graphics Display editor, double-click the object to open its Properties dialog box.
2. Click the Timing tab.
3. Specify the handshaking settings to use with the button.
