Problems acquiring and saving multiple camera images using a switch with GigE cameras

[CathyUCL]

Hi Folks,

We are having an issue with connecting 6 GigE cameras via an Ethernet switch. We can acquire and store individual cameras but once we increase the number of cameras we end up with jumpy avi files.

Each camera has been physically labelled and attached to the switch, so camera 1 is attached to port 1, which then corresponds to Cam1 in MAX. When recording multiple files what appears to happen is that the avi file from cam1 actually has images from multiple cameras, as if cam1 is being renamed/allocated on each frmae and each time a different camera is allocated. How can we fix this?

We are new to this so any help or advice would be much appreciated.

Thanks in advance,

Cathy

I think your problem is caused by using the same image name on each instance of Imaq create. "Grab and Save to AVI Acq" being the string you are using. I am pretty sure If you make each image name unique you wont get image referance problems.
