Length Control

Fixed Length Decoding —

When fixed length decoding is enabled, the scanner will decode a bar code if the label length matches one of the configurable fixed lengths.

Variable Length Decoding —

When variable length decoding is enabled, the scanner will decode a bar code if the label length falls in the range of the configurable minimum and maximum length.

Configuring Fixed Length Decoding:

1. Scan the START bar code.

2. Scan the Fixed Length Decoding bar code.

3. Scan the END bar code.

4. Set Length 1 to the first fixed length by following the

Code 39

Length 1, Length 2 Programming Instructions

below.

5. Set Length 2 to the second fixed length (or to ‘000’ if there is only one fixed length) by following the

Code 39 Length 1, Length 2 Programming Instructions

below.

Configuring Variable Length Decoding:

1. Scan the START bar code.

2. Scan the Variable Length Decoding bar code.

3. Scan the END bar code.

4. Set Length 1 to the minimum length by following the

Code 39

Length 1, Length 2 Programming Instructions

below.

5. Set Length 2 to the maximum length by following the

Code 39

Length 1, Length 2 Programming Instructions

below.
