(5) Setting unique specialized operation symbology
The terminal can be set to perform special actions when various barcode symbologies are scanned
and satisfy certain conditions. The code types, conditions, and operation content are as follows.
Barcode
Conditions
Operation
When barcode data
includes FNC2
Scanned barcode data including the FNC2
function character is temporarily stored in the
scanner. The stored data can be automatically
added at the forefront of the subsequent scanned
symbol data to be output.
*1, *2
When barcode data
includes FNC4
128 can be added to the ASCII value of the single
data character that follows after FNC4, and the
result output as an extended ASCII character. If
two sequentialFNC4 function characters are
scanned, either a group of two sequential FNC4
function characters are read, or “128” is added
automatically to each subsequent ASCII character
data following the two FNC4 characters until the
end of the symbol.
When the lead character is
FNC1
The scanned barcode is recognized as a GS1-128
(EAN128) code. The single data character that
follows after the lead FNC1 can be output as a
character GS(1DH).
When the character is
FNC1
The FNC1 character is not output.
Code128
When the third or later
character is FNC1
The single data character that follows after FNC1
can be output as a character GS(1DH).
*1 FNC2 for Code128 is an identifier that indicates linked barcodes. Even if a Code128 including
FNC2 is read, the scanner cannot output data as soon as it is read. After that, when a Code128
not including FNC2 is read, the data read up to that time is linked and output. The size of
combined symbol data is limited to 98 characters. If this is exceeded, the previous combined
symbol data that was scanned right before the exceeded combined symbol data are output.
*2 When using the trigger keys to scan barcodes which include FNC2,
Read one barcode with one scan operation on laser scanner models. The laser goes out after a
barcode is read, so scan each barcode individually. Finally, output the results after scanning a
barcode that does not include FNC2.
