PYLE Audio 7505-BTSDCMHC25 Parameter Scanning, Linear Security Level, Bi-Direction Redundancy

Chapter 5: Configuration

Decoded (Internal) Scanners

Parameter Scanning

Setting this parameter to on enables decoding of parameter bar codes.

Linear Security Level

This parameter allows you to select the security level appropriate for your bar code quality. There are four levels of decode security for linear code types (e.g., Code 39, Interleaved 2 of 5). Higher security levels should be selected for decreasing levels of bar code quality. As se- curity levels increase, the scanner’s decode speed decreases.

Double-tapping on this parameter displays a dialog box in which you can enter a value from 1 to 4.

Linear security level 1 specifies that the following code types must be successfully read twice before being decoded:

Code Type

Codabar

MSI Plessey

D 5 of 5

I 2 of 5

Length

All

4 or less

8 or less

8 or less

Linear security level 2 specifies that all types of codes must be successfully read twice before being decoded.

Linear security level 3 specifies that code types other than the following must be success- fully read twice before being decoded. The following codes must be read three times:

Code Type

MSI Plessey

D 2 of 5

I 2 of 5

Length

4 or less

8 or less

8 or less

Linear security level 4 requires that all code types be successfully read three times before being decoded.

Bi-Direction Redundancy

Note: This parameter is only valid if a” Linear Security Level” is enabled.
