"Insufficient resources for this video mode" error in IMAQ for IEEE-1394 1.1

[habil]

I'm using 3 Sony DFW-X700 cameras (1024x768 YUV 4:2:2) and 1 Sony XCD-X700 (1024x768 8-bit mono) connected to 2 IEEE-1394 adapter cards (3 ports each). I'm running LV 6.1 on WinXP Pro PT.
I've tried several acquisition modes, and the only one that works fine is 'continuous acquisition', using 1 buffer per camera. The problem is that I can only setup 2 color cameras and 1 mono camera. If I try to setup 3 color cameras, I get an 'insufficient resources for this video mode' error. I would like to know if it's possible to configure more memory for the acquisition buffers under IEEE-1394 so that I can avoid this error.

Habil,

You might want to try to lower the frame rate of the cameras. This error is caused because the driver is able to allocate only part of the firewire bandwidth for your image acquisition, and a three camera color acquisition requires a huge amount of bandwidth. This is currently an issue that our R&D department worked this period and is going to be resolved in the next release of the driver. This release should be ready in one month. Good luck!
