Introduction and Getting Started
Product Overview
The LH2 xed position imager is truly a revolutionary new 2D imager. The omnidirectional
decoding allows the reading of linear, stacked linear and matrix bar codes in any
orientation.
These state-of-the-art imagers with superior 32-Bit, 400 mHz microprocessors provide a
one piece solution combining illumination, imaging and decoding in an extremely small
package.
Dual optics used by the 1.3 million pixel SXGA (1280 x 1024) CMOS sensor provide
exceptional depth of eld. The near and far eld cameras can be programmed to be
switched ON and OFF in different combinations to tailor the reading capabilities of the
LH2 to t your applications.
The laser beam facilitates targeting. The adjustable targeting zone allows precise selection
of specic bar codes in the eld of view. The LH2 can be customized with advanced logic
through the internal embedded application engine. The embedded engine may be utilized
to intelligently process or manipulate scanned data before it is sent to an application.
Advanced functions such as Barcode Readability Index provide quantitative measures
for optimizing imager settings to realize maximum performance. The LH2 is rugged and
built to last. These 100% solid state imagers use proven CMOS technology, assuring
continuing performance and high reliability. It is designed for rough handling in tough
environments and has a small footprint to t into tight spaces.
The LH2 is available in standard RS232 interface. Custom mounting options, cable
lengths, connector types and pinouts are available.

Quick Start-Up Procedure
This section is for those who wish to start using the imager before reading the complete
manual. In only a few steps the imager will be operable.
Follow the appropriate steps depending upon whether your LH2 is congured to operate
with a RS232 interface.
Turn off the power to your PC and connect the imager to the RS232 communications port
depending on your cable conguration.
Note: You must provide +5 Volt DC power to the imager. This can be accomplished using
the power supply available from Opticon. If the power supply is obtained from another
source verify that it is identied with the CE mark. Turn on the power to the PC.
1) If you are operating in a Microsoft Windows 95/98/ 2000/ XP environment, you can set
the communication parameters using Hyper Terminal as follows:
• Open Hyper Terminal.
This can be done from Start>Programs>Accessories> Communications
• Select Hypertrm.exe to create a New Connection
• In the Connection Description dialog screen enter a name for the new le. If
desired, select an Icon. Click OK
• In the Connect To (Phone Number) dialog screen, in the box entitled: Connect
using. Select the communication port, for example, “Direct to Com 1” Click OK
• In the Com 1 Properties screen, enter the appropriate Port Settings:
Bits per second = 57600
Data bits = 8
Parity = None
Stop Character = 1
Handshaking = None
Click OK
• The hyper-terminal folder you just created will open. From the File pull-down
menu, select Properties then click on the Setting Tab
• In the Properties Settings dialog screen, Select Terminal keys for the Function,
arrow and control key; then Select ANSI for Emulation; the Back scroll buffer line
can remain at the default 500
