2. HANDLING PRECAUTIONS
There are some standard precautions that should be followed when handling the Neural Network
Controller (NNC) card or any other electronic hardware component:
1. Keep the card in its anti-static bag until it is ready to be installed.
2. Protect the card from static electricity by grounding your body and the equipment during
installation. Wear a grounded wrist strap, or touch the metal case or chassis of the PC before
touching the card.
3. Always grasp the card by its edges.
4. Do not touch the components on the card or the “gold finger” connectors plugged into the
expansion slot. Instead, grasp the card by its mounting bracket.
5. Ensure the system power is completely turned-off before doing any installation work. In case
of PCs with ATX power supplies, it is recommended to unplug the power cord before
installation.
During hardware installation, exercise caution when handling hardware components as
these might have sharp edges or protruding parts that can cause hand injuries.

4. INSTALLING CARMEN®OCR
4.1. SYSTEM REQUIREMENTS
Minimum system requirements:
•Intel Pentium III 1GHz CPU or higher (or any other fast x86 or x64 compatible CPU)
•512 Mbytes of RAM or more
•Free PCIe or miniPCIe slot with bus mastering option or USB 2.0 port
•Windows 8, 8.1, 10 32/64 bit operating system
•For CARMEN®OCR: image files (.jpg, .bmp, .png, .jpeg2000) loaded from a mass storage drive
or directly from memory as input
In order to run CARMEN®OCR, you should either have a USB 2.0 port / internal USB NNC or
PCIe / miniPCIe NNC. This is a form of HW protection for the software, the dongle includes the
license.

4.2. HARDWARE INSTALLATION
4.2.1. Installation of the PCIe (x1) NNC
1. Turn the computer off and unplug the power cord.
2. Remove the cover from the computer (refer to the user’s manual of the PC for specific
instructions).
3. Locate an available empty PCIe expansion slot.
4. Remove the slot cover screw and slot cover if possible.
5. Open the antistatic protective sleeve of the CARMEN®NNC card, grasp the circuit board by
the edge of its mounting bracket and take it out from the sleeve.
6. Insert the card into the empty PCIe expansion slot by its gold finger connectors and gently
press down on the top edges of the board to ensure that all connecting points are seated
securely. Fasten the mounting bracket of the board using the screw removed earlier.
7. Reinstall the cover of the PC and reconnect the power cord.
8. Turn the computer on.
9. During system boot, enter the BIOS setup program of the computer and check whether the
Bus mastering option is enabled. If not, enable it. Save and exit setup. (This option is not
available in every BIOS setup program; check the user’s manual of the PC for specific
information).
10. When the New Hardware Found wizard starts, click on [Cancel].
4.2.2. Installation of the USB 2.0 port NNC
1. Connect the NNC to one of the USB 2.0 ports of the computer.
2. The key will only be detected and recognized once the software package has been installed.

4.3. SOFTWARE INSTALLATION
Download links for the CARMEN®Installation Package are distributed via the ARH Technical
Support System (ATSS). The links are sent out automatically once your order is processed. If you
did not receive a download link, please open a ticket in ATSS.
4.3.1. Installation on Windows platforms
1. Before installing a new CARMEN®OCR version, uninstall any previous versions of CARMEN®
OCR from your system (if applicable) and reboot the computer.
2. Extract the received zip file to a folder on the hard disk of your computer.
3. CARMEN®setup does not start automatically; locate and double-click “ CARMEN OCR-
7.3.X.XX-x86.msi” (32bit version) or “ CARMEN OCR-7.3.X.XX-x64.msi” (64bit version) within
the Installation Package to start the installation.
4. Follow the installation steps and accept the END-USER LICENSE AGREEMENT

5. INPUT IMAGE REQUIREMENTS:
5.1. CHARACTER SIZE
For optimal OCR results, the most important factor is the size of the characters on the image.
For Latin characters it is recommended to have an average character height of at least 16 pixels.
For optimum results, it is recommended to have characters that are at least 20 pixels in height.
Very low-resolution images are unusable for OCR, but so are very high-resolution images as well.
Therefore, avoid settings where the character height is greater than 50 pixels. The line width of
a character on the image should be at least 2-3 pixels.
Recommended character sizes in pixels:
•Height, Latin characters: 16-50 pixels (optimal 20-50)
•Line width: min. 2-3 pixels
Proper character sizes (in pixels) on a sample
image of a container code (ACCR)
