5 Barcode data capture

5.1 Introduction

The H-32 provides two types of barcode data capture options:

1D Laser scanner

2D Imager
5.1.1 1D laser scanner
H-32 with the 1D laser scanner holds the Opticon MDL2001 laser module.
Benefits:

Reading a wide variety of 1D barcode types

Fast scanning

Intuitive aiming for easy point and shoot operation

Lower power consumption compared to 2D imager

Scan PDF417, MicroPDF417, RSS composite and RSS stacked barcode types
(slow)
5.1.2 2D imager
The H-32 with the 2D imager holds the Opticon MDI3100 barcode imager.
Benefits:

Reading a wide variety of 1D and 2D barcodes

Intuitive green aiming LED for easy scanning

5.2 Scanning consideration

Scanning a barcode consist of the following operation, aim, scan and decode. To get
better scanning performances consider vary the range and the scan angle of the H-32.
5.2.1

Range

Any scanning device decodes well over a particular working range (minimum and maximum
distances from the bar code). This range varies according to bar code density and scanning
device optics.
Scanning within range brings quick and constant decodes; scanning too close or too far away
prevents decoding of the barcode. Move the H-32 closer or further away to find the best
working range for the barcodes being scanned. The best range can vary based on barcode
type, density, barcode quality, lighting conditions.
5.2.2

Angle

For the laser module scan angle is important for good decoding performance. When a
laser beam reflects directly back into scan module it can blind the module preventing it
from being able to decode the barcode. To avoid this tilt the H-32 so that the laser beam
does not have a 90° angle to the barcode.
