The ROV scanner appends a 4 digit serialization number to each scanned bar-code. This serialization number is sent (along with the barcode data) to the receiver. The receiving device is required to acknowledge the bar-code by sending back the serialization number along with an appended ACK character (hex 06) to the ROV scanner.

The built-in scripting capabilities enable you to process the received data (e.g. send the data to any application by simulating keystrokes) or to implement the confirmation scenario outlined above.
