Decode Redundancy
Use this parameter to indicate whether the scanner must read a bar code one
time (LEVEL 1), two times (LEVEL 2), or three times (LEVEL 3) before
decoding it. A higher level of redundancy ensures the accuracy of a decode in,
for example, poor quality symbols.

UPC-A and -E Preamble
Three options are given for the lead-in characters of decoded UPC-A or UPC-
E symbols transmitted to the host device. Select one preamble for UPC-A
decodes and one for UPC-E decodes. These lead-in characters are considered
part of the symbol itself. The three options are:
E symbols transmitted to the host device. Select one preamble for UPC-A
decodes and one for UPC-E decodes. These lead-in characters are considered
part of the symbol itself. The three options are:
•
a system character only
•
the country code and system character
•
no preamble
The system character is the digit printed to the extreme left of a UPC symbol.
The country code for UPC is always zero, and it cannot be transmitted without
the system character.
The country code for UPC is always zero, and it cannot be transmitted without
the system character.
Pause Duration
This parameter, used in data editing, allows a pause to be inserted 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 1/10 second intervals. For example,
scanning bar codes “0” and “1” will insert a 1/10 second pause; “0” and “5”
will give you a 1/2 second delay.

Prefix/Suffix Values
A prefix/suffix may be appended to scan and magstripe data, for use in data
editing. These values are set by scanning a four digit number (i.e., four bar
codes) that correspond to keycodes for various terminals. See the
