W1T: TCIF Linked Barcode 3 of 9 (TLC39)
TLC39 is a telecommunications barcode which encodes a six digit sequence in a standard 3 of 9 barcode (code 39) followed by a link flag character in code 3 of 9 and a 25 character alphanumeric serial number encoded in MicroPDF417.
Syntax:
a W1 t c d eee ffff gggg hhhhhh ; i…i
(note: spaces shown for clarity)
Where:
Field | Valid Inputs | Meaning |
a | 1,2,3, and 4 | Rotation |
W1 | W1 | Fixed value, extended barcode set |
t | t | Selects TLC39 barcode |
c | 0 to 9 and A to O | Wide bar of Code 39, ratio of wide to narrow must be between 2:1 and 3:1 |
d | 0 to 9 and A to O | Narrow bar of Code 39 |
eee | 001 to 999 | Height of Code 39 |
ffff | 0000 to 9999 | Label position, row |
gggg | 0000 to 9999 | Label position, column |
hhhhhh | ECI Data | Six digit ECI number |
; | Fixed | Parses data |
i…i | S/N Data | Up to 25 alphanumeric serial number |
NOTES:
•The ECI number must be six digits followed by a semi colon. If the seventh character is not a semi colon then only a six digit code 39 will print.
•The link flag is the character “T” in code 39 without a start/stop indicator. The location of this flag is based on the ECI code location, length and height.
•The serial number may contain up to 25 alphanumeric characters and is encoded in the MicroPDF417 symbol. This symbol is fixed at 4 columns and the rows are determined based on the following:
Number of Alphanumeric Data | Number of Rows |
4 | |
6 | |
8 |
The location of the MicroPDF417 symbol is based on the location of ECI barcode. The symbol’s module width and height are fixed at the default.
The following example prints a TLC39 barcode.
