This manual provides the necessary instructions for installing and using an Opticon LH2 Fixed Position Imager. The manual is organized as follows: Chapter 1 Introduction and Getting Started Describes the general operation of a LH2 Fixed Position Imager. Also provides a Quick Start-Up Procedure that allows you to begin using the imager immediately.
The laser beam facilitates targeting. The adjustable targeting zone allows precise selection of specific bar codes in the field 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.
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 configured to operate with a RS232 interface.

Developer’s Test and Evaluation Kit is available that contain all the items needed to install and evaluate the LH2 imager. The LH2-R1-SK1 kit includes: • LH2 Imager • Cable (Connects LH2 to the Evaluation Board) • Engineering Test & Evaluation Board • 5V Power Supply • Extension Cable (Connects host PC to Evaluation Board)
Chapter Chapter 3 Positioning the Imager for Optimal Performance Achieving Optimum Performance Four items greatly impact performance: 1) Distance (from the scan window) to the bar code 2) Specular Reflection; and 3) Quality of Bar Code Labels 4) Imager field of view and resolution 1) Distance to the Bar Code The operation of the imager is similar to a camera.

The following chart in figure 3.1 shows the “typical” depth-of-field (closest to farthest reading distances ) for the LH2 imagers. The actual performance may differ slightly from unit to unit. Also, it is important to note that this data was measured under ideal conditions using high quality bar code labels.
Barcode Readability Index The Readability Index provides a measurement of a specific symbol’s ease or difficulty to be decoded by the LH2. The Readability Index is specific to the LH2, and should not be confused with a verification quality measurement.
Code Readability Index Rule: The Reader will store the rule and reset, but will not output the Readability Index until the Readability Index Output Enable code is read. To remove this rule, scan the Clear All Prefix & Suffix code in Appendix A. Readability Index Output Enable Once read, each time a data symbol is read, the index will be output, followed by a comma, (,) followed by the decoded data.
4) Imager Field of View & Resolution The LH2’s dual field optical system may be modified based on your scanning environment. The LH2’s mega pixel imager may be set to the following two modes: SXGA Mode: In standard SXGA mode (default), the 1.3 Million Pixel imager is divided into near field and far field decode zones.
400 MHz processor. If you are scanning large barcodes, small barcodes or even multiple sizes of different barcodes, by defining the working range and the type of symbols the reader must process, the LH2 will offer lightning fast decodes.

In order to achieve high density, the individual elements of a symbol must shrink. The highest density symbols can only be resolved in the LH2 near-field image, where the resolution of the imager is 1024 x 640 DPI. Symbol density is usually expressed in “Mils” - ie, thousandths of inches.

• Program the imager to higher Decode Time. For example, program the imager to decode a bar code exactly the same way with Extra Long Decode Time before transmitting the data. The default settings for the LH2 are designed for optimal, general purpose performance with good quality symbols on typical surfaces. For...
Chapter 4 Configuring the Imager Since the operation of a LH2 imager is microprocessor controlled, it is possible to modify or program its operation to match your specific application. Changes in parameter settings can be changed or programmed in two ways: (1) The first method employs specially designed programming bar codes which instruct the imager to modify specific parameters.
Application Engineering Support Technical Assistance and Support Opticon is eager to help you integrate the LH2 imager into your application. Our technical support staff is available to answer any questions or work with you to adapt the imager to your specific situation.
Imagers can be modified in terms of connectors type, pin-outs, cable length, default settings, custom software and many other areas. Opticon will modify imagers in our factory and ship you imagers that match your specific requirements. By incorporating your modifications directly into production imagers, you receive imagers tailored for your need.
Chapter 6 Imager Servicing and Maintenance The LH2 imager contains no user adjustable or serviceable parts in the interior of the imager. All product service must be performed by the Opticon Service Department in Orangeburg, NY. Opening the imager will void the warranty and could expose the operator to laser light.
Appendix A Programming Menus & Commands How to use the Appendix? The appendix has all the programming commands laid out in a standard format in the whole section. All the programming commands have these attributes - Command Name, Usage, Description, Default, Programming Code, Note and Options. For certain commands you might not have all the attributes and are intentionally not mentioned.
You can scan multiple programming barcodes to change the settings. NOTE: Always scan the “Save Settings“ bar code to save all the changes you made. If you do not save the settings then the next time you power ON the LH2, it will go to the previously saved settings.
Up Procedure to set up the HyperTerminal program. After setting the connection use the Transfer pull-down menu, select “Send Text File...“ (figure) and then select the file you want to send to the LH2. The CRB file allows for combining multiple functions into a single file.
For example you can create a test.crb file that contains commands to enable Aztec symbology and make the reader beep three times. Note you can also comment your CRB file with a semicolon (;) as shown below. NOTE: The only command which is not ignored in the CRB file when a semicolon (;) is used is ;>PA7.
