USB Barcodes with Unknown Characters

USB Barcodes with Unknown Characters

This option applies only to the USB HID Keyboard and IBM devices. Unknown characters are characters the host does not recognize. Select Send Barcodes With Unknown Characters to send all barcode data except for unknown characters. The scanner does not issue error beeps.
Select Do Not Send Barcodes With Unknown Characters for IBM devices to prevent sending barcodes that contain at least one unknown character to the host, or for USB HID Keyboard devices to send the barcode characters up to the unknown character. The scanner issues an error beep.
