Using Transfer Queue Current Block Count with CamExpert
This feature returns the number of frames buffered within the camera pending transfer to the host
system. Image lines/frames are buffered in cases where the host system is experiencing high
network traffic with other devices through the same Ethernet switch.
By buffering image frames, the camera will not drop data when there are temporary
delays to the transfer.
When using CamExpert, right-click on this parameter and then select
Refresh
from the context
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. Review the Troubleshooting section and contact
Technical Support for help in reviewing your camera setup.
The ImageLost event occurs when all buffer space is consumed.
Overview of Transfer Control (
TransferControlMode
)
Linea2 5GigE acquisition transfers operate either in the basic coupled mode or in an independent
decoupled user controlled mode, as described below.
TransferControlMode =
Basic
Basic Transfer Mode provides maximum compatibility with any control application running on the
host computer. The host-based acquisition program commands the camera to do a frame grab and
send it through the camera’s frame buffer to the camera’s transfer m
odule and the host. The
acquisition rate is limited by the host transfer rate.
