⚙️ App Settings
The App Settings page configures how the scanner communicates to apps by entering characters before and after the scanned bar code. If these are not configured, the scanner will simply insert the bar code number as text and it won't function in an automatic way.
-
Scroll down to the End Mark section, and make sure Enter is checked.
-
In the Data Format section, insert a tilde "~" in the Prefix field, and leave Suffix blank. The tilde ~ can be found on the symbols portion of your keyboard.
Some applications can configure their own overrides to the expected Prefix and End Mark. If you modify these values manually, you need to make sure the App Settings on the device match accordingly.
