(2) Scanner ID
A scanner ID is a unique serial number assigned to an individual scanner at the time of shipment. It consists of six
numerals.
(3) Prefix/Suffix
A prefix or suffix consists of up to eight ASCII characters (00h to FFh). You can set a prefix or suffix with the
configuration software (ScannerSetting_2D). (Default: No prefix or suffix)
(4) BCC
The Block Character Check (BCC) exclusive-ORs all bits at the same bit level in characters following the header and
preceding the terminator in a transmission block to generate a horizontal parity byte to be transferred in a binary code.
The BCC can be enabled or disabled. If no header is prefixed or the USB keyboard interface is selected, no BCC will
be transferred.
