Note:
1. By default, the alphanumeric key is used for trasmitting digits. Scan NUMERIC KEY if you want
to use the keys on the numeric keypad.
2. If you select NUMERIC KEY, the Num Lock status of the physical keyboard should be ON.

BCC (Binary Check Character)
On
Off*
Note:
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 <CR><LF>
1. BT SPP & USB VCP:
Data Format = <T> + <E> + <S> + <T> + <CR> + <LF> + <BCC>.
BCC = 54h ^ 45h ^ 53h ^ 54h ^ 0Dh ^ 0Ah = 11h
2. BT HID & USB HID:
Data Format = <T> + <E> + <S> + <T> + <Enter> + <BCC>
BCC = 54h ^ 45h ^ 53h ^ 54h ^ E7h = F1h
However, since control character 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
