mum. To update the rmware:
Connect your reader to the DataMan Setup Tool.
Choose System->Update Firmware.
Select the le DM7xx0_v2.1.1_rc1.bin.gz from the directory
Cognex\DataMan\Firmware\DM7500 Series.
To enable the DPMV feature, you must upload a feature key le to the
reader:
Connect the reader to the DataMan Setup Tool.
Choose System->Upload Feature Key
Select the feature key le that you receive from Cognex.

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

verication results, perform the following steps:
The verier stand-off must be used to ensure correct symbol presentation
and lighting requirements for the AIM DPM Quality Guideline.

Code Quality: Formatting Output Data
Use the Data Formatting task pane of the DataMan Setup Tool to construct
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.
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.
Select View->Advanced if the DataMan Setup Tool is not in Advanced
mode.
Select the Data Logging task pane under System Settings.
Enable Code Quality Results and use the Save in option to cong-
ure a directory location to save each report along with an image of the
veried symbol, as shown in the following example:

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.
Be aware, however, that 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 online documentation.
