Large Linear Verification Kit Quick Start Guide Accessories The required accessories are an Ethernet cable for the camera, a power supply, and power cables for the camera and lighting. The selection of accessories depends on the details of the installation, such as required cable length, availability of suitable power, and whether the installation will employ continuous or strobed lighting. The minimum set of accessories required to complete a bench-top installation is shown below. In the configuration shown, the HAWK MV-4000 camera and the illuminator share a power supply via a QX-1 Connection Block.

Large Linear Verification Kit Quick Start Guide Mounting Positions The Large Linear Verification Kit is designed to provide flexibility in the mounting of the camera and the lighting elements of the system while maintaining the 45 degree lighting angle required by the ISO specification. The principal mounting components are two aluminum extrusions (“long” and “short”) and accessory items provided in the MAX 300 Bracket Kit (P/N 98-000268-01 ). The “long” and “short” extrusions can be assembled in two different configurations for additional flexibility. In one configuration the “long” extrusion is the vertical element. It is used to mount the camera by means of the supplied mounting plate.
The “short” extrusion mounts the light by means of the supplied angle bracket. In the other configuration the “short” extrusion is the vertical element. It is used to mount the camera by means of the supplied mounting plate. The “long” extrusion will mount the light by means of the supplied angle bracket. Note: The second configuration allows for shorter working distances and, therefore, a smaller field of view. Mounting Options and Hardware The MAX 300 Bracket Kit contains two L brackets and associated fasteners that can be used to mount the kit to a customer-supplied mounting location. The L brackets attach to slots in the extruded rail by means of supplied machine screws and T nuts.
The bracket kit also contains a lighting mount bracket and associated fasteners which are used to mount the light on the appropriate extrusion. The camera is mounted by means of a supplied camera mounting plate and associated hardware. Note: See the NERLITE Smart Series MAX 300 Bracket Kit Quick Start Guide (P/N 83-9200056-04 ) in Omron Microscan’s Download Center at www.microscan.com and on the Microscan Tools Drive (P/N 37-000010-01 ) for more detailed information about mounting options and hardware. The guide is also available in printed form in the MAX 300 Bracket Kit (P/N 98-9000120-01 ). L Bracket Lighting Mount Bracket 3 Copyright ©2018 Omron Microscan Systems, Inc.
Large Linear Verification Kit Quick Start Guide Applicability to Verification Standards The Large Linear Verification Kit supplies a camera and lighting configuration that is consistent with the requirements of ISO 15416 (Information Technology – Automatic Identification and Data Capture Techniques – Bar Code Print Quality Test Specification – Linear Symbols) . AutoVISION 2.0 / Visionscape 6.0 and higher support the grading methodologies defined in these standards for the following 1D symbologies: The constraints on the use of the system in terms of maximum symbol size and minimum size of the narrow bar are reflected in the table below.
In the case of large symbols, care must be taken to include the quiet zone within the area that is evenly illuminated. For small symbols, the configuration chosen must ensure that at least 8 pixels cover the width of the smallest symbol element. The minimum 1D symbol element (cell size) that will give the required number of pixels per element with the supplied camera and lens is as follows: Lighting Configurations The ISO 15416 standard reference geometry specifies that the camera must be mounted perpendicular to the symbol surface. The reference geometry also requires that the code be illuminated at an angle of 45 degrees.
The ISO 15416 grading process will result in a significantly reduced grade if all parts of the symbol do not receive the same degree of illumination. Great care should be taken to ensure that even illumination is achieved along the length of the symbol and over the two quiet zones. The minimum narrow bar size required to achieve the minimum recommended resolution of 8 pixels per narrow bar is shown below in the Minimum Bar Size vs. Working Distance chart. The field of view sizes that can be achieved with the HAWK MV-4000 Smart Camera and lens combination included with the Large Linear Verification Kit are shown in the Horizontal FOV vs. Working Distance chart.
