Slope (%) field | Enter the value in the text field | Sets the slope of the carriage number in relation to the video image received from the camera in percent. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up. | Percent | 1 | <>=0 |

Minimum |
| Min. contrast field | Enter the value in the text field | Sets the estimated difference between the shades of gray of the LP symbols and the background. | Shades of gray | 15 | >=0 |
| X in Y (%) field | Enter the value in the text field | Sets the rate of the horizontal symbol resolution to the vertical one in percent. The horizontal resolution is the ratio of the symbol width on the video image to its actual width, and the vertical resolution is the ratio of the symbol height on the video image to its real height. If you put Zero or negative value, then the value will automatically changed to 100. | Percent | 100 | >=0 |
Delay field
| Enter the value in the text field |
Sets the time interval in milliseconds that should expire in order for the recognition module to display the next number recognition result. A value of zero means no delay. | Milliseconds | Sets the minimum height of the carriage number symbol in the video image from the camera

Slope (%)
| Enter the value in the text field | Sets the slope of the carriage number in relation to the video image received from the camera. The value is positive if the horizontal axis of the LP symbols is tilted down when viewed from left to right, and negative if this axis is tilted up | Percent | 1 | <>=0 |

X in Y (%)
| Enter the value in the text field | Sets the ratio of the horizontal and vertical symbol resolution. The horizontal resolution is the ratio of the symbol width on the video image to its actual width, and the vertical resolution is the ratio of the symbol height on the video image to its real height. If you enter zero or a negative value, then the value will automatically changed to 100 | Percent | 100 | >=0

| Delay | Enter the value in the text field | Sets the time interval in milliseconds that should expire in order for the recognition module to display the next number recognition result. A value of zero means no delay | Milliseconds | 1000 | >=0 |
| 4 | The Filters group |
| ISO filter |
ISO filter checkbox | Set the checkbox | Enables the |
ISO carriage | ISO carriage numbers filtering. When reading a number that consists of 11 symbols, the recognition module will attempt to read the ISO code (examples of ISO codes: GB4310, 22G1) |
.YesYes - Set—the filtering is enabled |
No - the filtering Clear—the filtering is disabled |
| Long code filter |
checkbox | Set the checkbox | Enables the long numbers filtering. If the video image does not contain |
the carriage | the carriage number, but contains some other text, the recognition module can display a |
false carriage | false carriage number. The long numbers filtering reduces the likelihood of the false |
numbers | codes appearing, increases the runtime (by about 5%), and degrades the recognition of |
the carriage | the carriage codes on the images with |
a carriage | a carriage code (by about 0.5%) | - |
YesYes - Set—the filtering is enabled |
No - the filtering Clear—the filtering is disabled |
UIC filter wagon number checkbox| Checksum test | Set the checkbox | Enables the |
filtering UIC carriage numbers. If the check number in the carriage number does not match the expected check number according to the UIC standard, then this number will be ignored.| the checksum of the numbers | - |
NoYes - filtering No - the filtering Clear—the testing is disabled |
