Data Matrix Symbol Quality Verication

Cognex DataMan 8600 handheld veriers ensure that a Data Matrix sym-

bol meets the AIM DPM (Direct Part Mark) Quality Guideline.

The DataMan 8600 handheld veriers provide:

• Contract Compliance: The DataMan 8600 software, integrated lighting,

and xed optics meet the AIM DPM Quality Guideline.

• System Calibration: The DataMan 8600 verier includes a certied cali-

bration card necessary to calibrate the reader.

If you are upgrading a previously purchased DataMan 8600 reader

to be used as a verier, your reader must be using rmware version

5.4.0 CR1 at a minimum. To update the rmware:

1. Connect your reader to the DataMan Setup Tool.

2. Choose System->Update Firmware.

3. Select the le DM8600_v5.4.0_cr1.bin.gz from the directory where

the rmware update automatically navigates (Cognex\DataMan\

Firmware\DM8000 Series).

To enable the DPM Verication feature, you must upload a feature key

le to the reader:

1. Connect the reader to the DataMan Setup Tool.

2. Choose System->Upload Feature Key

3. Select the feature key le that you receive from Cognex.

4. The reader automatically reboots after the upgrade and it is ready

to use for verication.

Upgrading a Device for Verication

Getting Started: Stand-off Installation

Attach the stand-off carefully to your DataMan 8600 reader.

The stand-off

snap-ts into the

reader.

This way up

With a combination of 5mm, 7mm, and 10mm spacers, the following reading

distances can be set:

Getting Started: Stand-off Distances

The stand-off is an accessory that consists of a plastic frame that is attachable

to the device (see below) and various spacers. By threading in the right spac-

ers, different xed mechanical reading distances can be set.

• 20,3 mm

• 23,3 mm

• 25,3 mm (60° illumination)

• 30,3 mm

• 8,3 mm (without spacer – 30° illumination)

• 13,3 mm

• 15,3 mm (45° illumination - same distance as

DM7500 Verier stand-off)

• 18,3 mm

NOTE: 8.3 mm distance is required for AIM-DPM verication.

NOTE: If 5mm spacers are used in combination with other spacers, the 5mm spacers

must be placed on top due to their shorter internal thread.

Code Quality: Verication

5. Move the reader until the center of the red rectangle lies within the

green target rectangle. The reader beeps to indicate that the symbol has

been read and veried.

3. Select the Results Display task pane.

4. Place the verier against the symbol and squeeze the trigger. The sym-

bol must be centered within the eld of view, and the reader must be

perpendicular to the surface containing the symbol and at the correct ro-

tation. If the reader is out of position, the Setup Tool displays this guide:

2. Enable the Turn Code Quality On/Off icon in the tool bar.

In order to perform Direct Part Mark Verication, your reader must be

calibrated as described in the previous section. To read symbols and view

verication results, perform the following steps:

The verier stand-off must be used to ensure correct symbol presenta-

tion and lighting requirements for the AIM DPM Quality Guideline.

NOTE: You can activate Code Quality mode by navigating to the Code Quality Settings pane

and ticking the Code Quality Enabled box.

1. Start the DataMan Setup Tool and connect to your reader.

Getting Started: Calibration

1. Start the DataMan Setup Tool and connect to your reader.

2. Select the Code Quality Settings task pane.

3. Place the verier against the calibration card with the symbol

centered below the reader, and squeeze the trigger.

4. Continue squeezing the trigger. Calibration can take several seconds.

The Setup Tool displays a graphic guide if the symbol is not precisely

aligned with the reader; adjust the position and rotation of the reader

until the center of the red rectangle lies inside the green rectangle

and there is no more than 10 degrees rotation between the symbol and

the reader. The reader beeps once when calibration is complete.

Code Quality: Formatting Output Data

Use the Data Formatting task pane of the DataMan Setup Tool to con-

struct a customized output string each time you read and verify a symbol.

This allows the verier to return Code Quality results when connected to a

third-party application instead of the DataMan Setup Tool.

In addition to standard formatting, the DataMan Setup Tool supports the

use of Perl-Style Regular Expression features in Advanced mode.

NOTE: Consult the Q and

A of the Data Formatting

task pane for more detailed

information on how data

formatting works.

NOTE: Code Quality metrics

are available in script-based

formatting. Example snippet is

available at Insert Snippet-

>Simple formatting-

>Outputting Code quality

parameters.

For more detailed information,

please refer to the Communi-

cations and Programming

Guide.

Code Quality: Results

The Results Display task pane presents the results of the verica-

tion on the right-hand side.

For more information on interpreting the verication results, enable Q

and A (View->Q+A Help). The Results Display task pane can toggle

between displaying results and Q&A information.

Verication Conguration: Saving the Setup

Once you have congured your reader with the settings you want it to use,

choose System->Save Settings to save the conguration.

Choose File->Save Conguration to save the conguration to a directory

on the PC. A saved conguration can be opened later and uploaded to any

reader, allowing multiple readers to use the same conguration settings.

NOTE: Each reader must be calibrated individually.

Code Quality Conguration Codes

Use the following Code Quality conguration symbols to quickly turn

Code Quality on and off without connecting the reader to the DataMan

Setup Tool. Additional Code Quality Reader Conguration symbols are

available in the document Reader Conguration Codes.

Code Quality On

Code Quality Off

Code Quality: Logging Data

Use the Data Logging task pane to generate a Code Quality Report for each

symbol that you read and verify. Be aware that data logging works only when

the reader is connected to the DataMan Setup Tool.

In addition, you can enable the Prex lename with option to give each

Code Quality Report a set prex.

1. Select the Data Logging task pane under System Settings.

2. Use the Save in option under Report Storage to congure a directory

location to save each report as a pdf along with an image of the veri-

ed symbol, as shown in the following example:
