Publication 2755-6.3
UPC-A / UPC-E Preambles
The UPC preamble consists of the system character and country
code. The system character is the the first character on the left side
of the symbol. The country code for UPC is always 0. Select
whether these characters are sent with the bar code data:
• system character only
• country code and system character
• no preamble
Note: There are separate preamble programming codes for both
UPC-A and UPC-E symbols.
Pause Duration
When enabled, this parameter allows you to insert a pause at any
point in the data transmission. Pauses are set by scanning a two digit
number (i.e., two bar codes, and are measured in 0.1 second
increments).
Scan Prefix
To add prefix data to bar code data, scan the Prefix bar code
followed by the 4 digit (decimal) ASCII equivalent value for each
character. Only one character may be specified as a prefix. When
you enter the last digit of a prefix, the scanner lets you know that you
have entered a valid value by providing a high-low-high beep.
Scan Suffix
To add suffix data to bar code data, scan the Suffix bar code followed
by the 4 digit (decimal) ASCII equivalent value for each character.
Only one character may be specified as a suffix. When you enter the
last digit of a suffix, the scanner lets you know that you have entered
a valid value by providing a high-low-high beep.
