Chapter 3 Bar Codes
ratio Optional parameter (used in conjunction with 9
above) representing the ratios for variable ratio bar
codes. Default ratios are overridden by the variable
ratio feature. The ratio data must be hexadecimal
numbers from 0 through 9 or A through F. The
Code V automatically checks the input for validity. If
an invalid character is found in the ratio, an error
message is generated.
UPCSHIP bar codes use four-digit ratios. The
ratios are interpreted from left to right, measuring
the size of each bar or space, in dot width, in the
following pattern:
narrow bar : narrow space : wide
bar : wide space.
For example, enter 2266 in the
ratio parameter for:
2 dot-wide narrow bar
2 dot-wide narrow space
6 dot-wide wide bar
6 dot-wide wide space
The Code V automatically checks ratio data for validity only within the
allowable hexadecimal range. The Code V does not verify that ratio data
creates acceptable wide/narrow element relationships for bar code
readability. For example, the Code V accepts wide/narrow ratio values of 2
and 5, respectively; however a narrow element larger than the wide element
produces an unreadable bar code. When designing unique ratio data,
carefully plot wide and narrow ratios to conform to readable bar codes.
data The bar code data. The UPCSHIP bar code
requires exactly 13 characters of data. The
characters available for the data field are 0 through
9 (hex 30 through 39, respectively).
(cc)G Terminates the bar code command. Enter the
SFCC for your Code V configuration immediately
followed by any valid command character or G, the
universal sequence terminator.
