(1) Header/Terminator
The following choices are available.
Header: None (default) or STX
Terminator: CR (default), LF, CR/LF or ETX
For details, refer to Chapter 12.
(2) 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)
(3) 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, no BCC will be transferred.
