4.3 Output data transmit
4.3.1 Auto mode
Auto mode
ENABLE DISABLE
When out of range, the scanner will temporarily keep scanned data in its
memory buffer (2K RAM) until the buffer is full. When back in range, the
scanner will send all stored data back to the host.
NOTE: Auto mode will not function when Batch Mode is enabled, or no
connection is made beforehand.
BINARY CHECK CHARACTER
ENABLE DISABLE
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. Bluetooth SPP & USB-VCP:
Data Format = <T> + <E> + <S> + <T> + <CR> + <LF> + <BCC>. BCC =
54h ^ 45h ^ 53h ^ 54h ^ 0Dh ^ 0Ah = 11h
2. Bluetooth 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
