DECODED SETTINGS

Decode Supplementals

Supplementals are additionally appended characters (2 or 5) according to specific

code format conventions (e.g. UPC A+2, UPC E+2, EAN 8+2). Three options are

available:

Ignore

If the scanner comes across a UPC/EAN plus supplemental symbol, the

UPC/EAN is decoded, while the supplemental characters are ignored.

Decode

If the scanner comes across a UPC/EAN plus supplemental symbol, UPC/EAN

symbols without supplemental characters are not decoded.

Auto-discriminate

This parameter enables the scanner to differentiate and decode UPC/EAN

symbols with or without supplementals. This option should be used in conjunc-

tion with Supplemental Redundancy, below.

Note: To minimize possible invalid data transmissions, select either the Ignore or

Decode option when possible.

Supplemental Redundancy

With Auto-discriminate enabled, this parameter limits the number of times a symbol

without supplementals will be decoded before transmission. The options are:

5 times, 7 times, 10 times, or 15 times. Five or above is recommended when

scanning a mixture of bar codes with and without supplementals.

UPC/EAN Coupon Code

If this parameter is ON, the scanner can decode UPC-A, UPC-A with 2 supplemen-

tal characters, UPC-A with 5 supplemental characters, and UPC-A/EAN 128 bar

codes. The Auto-discriminate option under Decode Supplementals must be enabled.

UPC/EAN Security Level

There are four Levels of decode security for UPC/EAN bar codes: 0 to 3. Increasing

levels of security are provided for decreasing levels of bar code quality. There is an

inverse relationship between security and scanner aggressiveness, therefore only

choose the level of security needed for the application.
