Chunk FeaturesBasler scout 25910.6 Line Status AllThe Line Status All feature samples the status of all of the camera’s input lines and output lines eachtime an image acquisition is triggered. It then adds a chunk to each acquired image containing theline status information.The line status all information is a 32 bit value. As shown in Figure 82, certain bits in the value areassociated with each line and the bits will indicate the state of the lines. If a bit is 0, it indicates thatthe state of the associated line was low at the time of triggering. If a bit is 1, it indicates that the stateof the associated line is was high at the time of triggering.To enable the line status all chunk: Use the Chunk Selector to select the Line Status All chunk. Use the Chunk Enable parameter to set the value of the chunk to true.Once the line status all chunk is enabled, the camera will add a line status all chunk to eachacquired image.To retrieve data from a chunk appended to an image that has been received by your PC, you mustfirst run the image and its appended chunks through the chunk parser included in the pylon API.Once the chunk parser has been used, you can retrieve the line status all information by doing thefollowing: Read the value of the Chunk Line Status All parameter.You can set the Chunk Selector and Chunk Enable parameter value from within your applicationsoftware by using the pylon API. You can also run the parser and retrieve the chunk data. Thefollowing code snippets illustrate using the API to activate the chunk mode, enable the line statusall chunk, run the parser, and retrieve the line status all chunk data:// make chunk mode active and enable Line Status All chunkCamera.ChunkModeActive.SetValue( true );Camera.ChunkSelector.SetValue( ChunkSelector_LineStatusAll );Camera.ChunkEnable.SetValue( true );The chunk mode must be active before you can enable the line status all featureor any of the other chunk feature. Making the chunk mode inactive disables allchunk features.Indicates output line 1 stateIndicates output line 2 stateIndicates output line 3 stateIndicates output line 4 stateIndicates input line 1 stateIndicates input line 2 stateFig. 82: Line Status All Parameter Bits
