Using Transfer Queue Current Block Count with CamExpert
This feature returns the number of frames buffered within the Genie Nano pending transfer to the
host system. Image frames are buffered in cases where the host system is temporarily busy or
cases of high network traffic with other devices through the same Ethernet switch. By buffering
image frames, the Genie Nano will not need to drop frames when there are temporary delays to
the transfer.
When using CamExpert, right click on this field and then click on Refresh from the pop-up menu.
The current frame count in the transfer buffer is displayed in the Value field. During live grab, if the
number of frames in the transfer buffer is increasing, then there is a problem with the network or
host bandwidth being exceeded. The ImageLost event occurs when all buffer space is consumed.
“Acquisition Abort” Execution Exception with Model C4900
For the model C4900 (Aptina sensor) the AcquisitionAbort feature does not execute immediately,
as is the case for all other Nano models.
When aborting an acquisition with the C4900, the application needs to follow this sequence:
•
Set the feature AcquisitionStatusSelector=AcquisitionActive
•
Send the command AcquisitionAbort
•
Poll the status AcquisitionStatus until it is FALSE
