CxLetterScan camera settings

Here you will find all available settings for the CxLetterScan camera module .

ATTENTION!

These settings affect the correct functioning of the camera, the quality of the recorded images and the determination of addresses, barcodes and texts from the images.

The settings may therefore only be changed by administrators/experts!

Three lists with the possible settings are displayed. Certain settings depend on the type of camera connected; these appear in the corresponding list.

The type of camera currently connected can be seen in the General settings list in 001: Camera type .

To edit a value, click with the mouse on the Value column.

General settings: These settings are independent of the camera type.

General settings

Designation	Default value	Value range	Description
001: Camera type		None UNiiQA Vieworks	Read-Only! Displays the type of camera connected. The camera type is recognized automatically. Depending on the camera type, the corresponding settings apply.
100: Camera resolution Y-axis (length/direction) in pixels per meter	8202	6000..11800	Read-Only! Resolution of the camera in the Y-axis (length/direction) in pixels per meter.
200: Band correction factor in [mm/s] for the 2nd motor in the camera module	0	-100 - 100	Band correction factor for the 2nd motor in the camera module, with which this motor can be corrected so that it runs at the same speed as the 1st camera motor. This is required because the 2nd belt does not have an encoder and therefore cannot be controlled. When making the setting, please ensure that the speed stroke is set to 0, otherwise the 2nd camera motor will run faster by this factor.
300: Virtual extension of the camera module in additional time [ms]	0	0 - 1000	This setting is only relevant if a camera module is available on its own. The processing path is then very short. This setting can be used to add additional time for processing letters so that the letters still have time to be processed after being ejected at the end of the camera module.
310: Distance between the sensor and the start of the camera exposure [mm]	0	0 -255	Depending on the orientation of the sensor in front of the camera, a letter may arrive at the sensor before the camera starts recording because the letter is not yet above the camera. This is particularly the case if the sensor is directed forwards so as not to produce a light strip on the image. In this case, the camera has to wait with the recording, otherwise we have a black stripe at the beginning. In order to start recording correctly at the beginning of the stripe, this parameter defines the distance between the sensor and the start of camera recording. As a rule, this is between 0 and 10 millimeters. If this parameter is set too large, the camera will start recording too late and the letter will be cut off at the beginning.
400: Distance between letters with double feed separation [mm]	100	0 - 255	Maximum length in millimetres that is waited after the camera module stops until it starts up again if letters are pushed on top of each other. This waiting distance does not apply if a letter moves away from the sensor, creating a gap to the next letter.
410: Stop with double trigger separation for C4 letter [mm]	200	0 - 300	This setting defines at which position of the C4 letter on the camera's sensor the 1st camera motor should be stopped in order to carry out the double trigger separation. If this value is 0, double trigger detection is switched off. Please note that the default settings are the optimum values, do not change this setting without precise knowledge of the machine architecture.
420: Stop with double feed separation for C5 letter [mm]	150	0 - 300	This setting defines at which position of the C5 letter on the camera's sensor the 1st camera motor should be stopped in order to carry out the double trigger separation. If this value is 0, double trigger detection is switched off. Please note that the default settings are the optimum values, do not change this setting without precise knowledge of the machine architecture.
430: Stop with double trigger separation for C6 letter [mm]	150	0 - 300	This setting defines at which position of the C6 letter on the camera's sensor the 1st camera motor should be stopped in order to carry out the double trigger separation. If this value is 0, double trigger detection is switched off. Please note that the default settings are the optimum values, do not change this setting without precise knowledge of the machine architecture.
