UPC-A Redundancy
If you are encountering errors when reading UPC-A bar codes, you may
want to adjust the redundancy count. Redundancy adjusts the number of
times a bar code is decoded before transmission, which may reduce the
number of errors. Note that the higher the redundancy count, the longer it
will take to decode the bar code. To adjust the redundancy, scan the UPC-
A Redundancy bar code below, then scan a redundancy count between 0
and 10 on the Programming Chart inside the back cover of this manual.
Then scan the Save bar code.
Default = 0.
UPC-A/EAN-13 with Extended Coupon Code
Use the following codes to enable or disable UPC-A and EAN-13 with Extended
Coupon Code. When left on the default setting (Off), the engine treats Coupon
Codes and Extended Coupon Codes as single bar codes.
If you scan the Allow Concatenation code, when the engine sees the coupon
code and the extended coupon code in a single scan, it transmits both as sepa-
rate symbologies. Otherwise, it transmits the first coupon code it reads.
If you scan the Require Concatenation code, the engine must see and read
the coupon code and extended coupon code in a single read to transmit the
data. No data is output unless both codes are read.
Default = Off.
UPC-A/Code 128 Coupon Code Output
If you scan the Multiple Code Output code, when the engine sees the
coupon code and the Code 128 code in a single scan, it transmits both as
separate bar codes with separate terminators.
