Barcode symbology identifiers

A sequence of characters generated by the bar code reader that identifies tha symbology from which tha data has been decoded. This sequence isn't stored in the data, identifies is added as prefix by the reader. In the settings of the reader you can set on/off generate this sequence.


Structure of the Symbology identifier (SI) :
- contain three chars:
] - SI indicator ( ASCII value 93 )
c - Symbology Identification
m - modifier

PDF417 / Micro DPF417

]L0Reader set to conform with protocol defined in 1994 PDF417 symbology specifications.

When this option is trasmitted, the receiver connot determine reliably whether ECIs have bebb invoked, nor whether data byte 92 has been doubled in transmission.
]L1Reader set follow the protocol of this standard for Exctended Channel Interpretation. All data characters 92 are doubled.
]L2Reader set follow the protocol of this standard for Basic Chanel operation. Data characters 92 are not doubled.

When decoders are set to this mode, unbuffered Structued Append symbols and symbols requiring the decored by convey ECI sequences cannot be transmitted.
]L3Code 128 emulation : implied FNC1 in first position
]L4Code 128 emulation : implied FNC1 after initial letter or pair odf digits
]L5Code 128 emulation: no implied FNC1
Note : Modifier 3,4,5 are applicable only to Micro PDF417 symbols.
