The 1D Code Types screen has the following functions:
Inverse 1D – Enable/disable inverse 1D bar codes or select
„
Auto Detect.
Enable/disable the 1D code types listed.
„
Tap Options to configure 1D code type specific settings. A
horizontal scrolling menu is shown near the top of the screen
with options for Code 39, Code 128/Code 93/Discrete, UPC/
EAN 1, UPC/EAN 2, Interleaved GS1 DataBar, MSI Plessey,
Codabar/Code 11, and Matrix 2 of 5. Depending on which
1D barcodes you are going to read, you should review the
options and configure them for your needs.
For example, below is the screen for Code 39:
Set Length: This option allows you to specify the length of
the barcodes you want to read. This could be useful if you
know that all valid barcodes will be a specific length or a
range of lengths.
You can specify four barcode lengths (let A refer to the first
length field and B refer to the second length field):
One Discrete Length – Set A to the discrete length and
„
B to 0. Only barcodes with an exact length of A are
decoded.
Two Discrete Lengths – Set A greater than B (both non-
„
zero). Only barcodes with lengths A or B are decoded.
Length Within Range – Set A less than B (both non-zero).
„
Barcodes between and including A and B are decoded.
Any length – Set A to 0. Any barcode length is decoded.
