The way the input works is if you configure the prefix/suffix property with a character, it will listen and record characters between them. For example, if you set prefix to ! and the suffix property to @. Then start preview mode and type !asdf@, asdf will get recorded.
Your ScanSKU app should have a setting to add prefixes and suffixes. If you set the prefix and suffix for the scanner to be the same as the Barcode Scanner Input, it should then start working because your scanner will send a string of characters like !GLW1234567@ instead of just GLW1234567.
