# Set up handshaking for a Numeric Input Enable button

When the operator presses the Enter button, the numeric pop-up keypad or scratchpad 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 on the Connections tab. These settings do not apply when ramping a value.

## To set up handshaking for the button

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