For managing multiple cameras, refer to the sample code: https://github.com/basler/pypylon/blob/master/samples/grabmultiplecameras.py prepare the for software trigger and execute the software command to specific camera and call retriebresult.

Now simply try to extend this code to following. Most properly it will work. if genicam.IsWritable(cam.ChunkModeActive): cam.ChunkModeActive = True print(cam.ChunkModeActive.Value)

does the camera work in pylonviewer?

@Zhefei777 Contact your local Basler’s distributor and ask for latest firmware file for this camera

the time stamp in grabresult and chunk is the same. < that time it is not accurate> would you explain in detail your statement,please?

in USB camera, the time stamp in chunk as well as in grabresult given in ticks = 1ns. You need to convert ticks into Daytime.

Would you share some information on your hardware and OS? How long is the USB Cable? Limit the camera parameter DeviceLinkThroughput Limit on 163000000 Byte/s

try this value camera.DeviceLinkThroughputLimit.SetValue(300000000)

Using a lower value helps you?

would you tell me the which camera model are you using and its SN? or turn to your local distributor to get the firmware update
