- Turn off "Physical keyboard", or turn on "On-screen keyboard". The Touch Keyboard will then function properly.
Interface
There are 5 interfaces for data transmission/collection:
- BT HID: Emulates a Bluetooth HID keyboard that transmits each barcode data to the host after decode.
- BT SPP: Emulates a Bluetooth SPP device that transmits each barcode data to the host after decode.
- Memory Mode: Emulates a USB mass storage device that saves each barcode data during off-line data collection.
- USB HID: Emulates a USB keyboard that transmits each barcode data to the host after decode.
- USB VCP: Emulates a USB virtual COM device that transmits each barcode data to the host after decode.

Power Off Timeout
The period of inactivity before auto power-off.
Variable Timeout
You can set the timeout in minutes and seconds (Range: 00 ~ 60).
The default timeout is 3 minutes 0 second. To set the timeout to 5 minutes 30 seconds:
- Scan [Set Minute].
- Scan [0] & [5] on pages 11 & 12.
- Scan [Set Minute].
- Scan [Set Second].
- Scan [3] & [0] on pages 11 & 12.
- Scan [Set Second].
No Timeout (Scanner Always On)
Scan the [DISABLE TIMEOUT] barcode.
Binary Check Character
Once enabled, a checksum will be added to the end of each data to conduct Xor calculation. For Bluetooth SPP & USB-VCP, the BCC is 1 byte. For Bluetooth HID, the BCC are 2 bytes.
Example: The barcode data is “TEST” with terminator
- Bluetooth SPP & USB-VCP: Data Format = <T> + <E> + <S> + <T> + <CR> + <LF> + <BCC>. BCC = 54h ^ 45h ^ 53h ^ 54h ^ ODh ^ 0Ah = 11h
- Bluetooth HID: Data Format = <T> + <E> + <S> + <T> + <Enter> + <BCC> BCC = 54h ^ 45h ^ 53h ^ 54h ^ E7h = F1h
However, since control characters cannot be displayed in Bluetooth HID, BCC will be converted into 2 bytes of characters. As a result, the data will be: TEST + <Enter> + F + 1
