Problem with FireWire (IEEE1394) speed - no more then 100Mbit/s

[BordoSlo]

Hello guys,

I have a problem with the speed of the FireWire bus.

I am using a ImagingSource camera model DFK21BF04, its a CCD FireWire color camera.

The problem appears when I want more then 15fps in BY8 (black and withe) mode and more then 3,75fps in UYVY (color mode). I think that the main problem is that I cant set a higher speed then 100mbit/s.

The driver is NI-IMAQdx IIDC Digital Camera.

The computer I am using is a Matrix MXE - 1020S. It is an industrial computer with 2 FireWire (9pin) ports.

The camera has a 6pin(400Mbit/s) connector and the computer has a 9 pin connector (800mbit/s).

So this should work on 400mbit/s.

So when i want a higher fps rate an error appears. (Picture 3)

Please help me.

Tnx

Hi BordoSlo,

Which OS is installed on your industrial computer? Similar behavior was reported already due to Win7 IEEE1394 driver issue. 

The forum post under this link, talks a bit more in details about this issue. It seems that using the Legacy 1394 driver solved the isse for some customers.

I hope this will help.

Hello,

The OS was XPsp2 until I found a possible solution in the industrial computer manual that the 9pin FireWire connector may have some problems in XPsp2 and that there should not be any problems if I upgrade the OS to XPsp3. So now the OS is XPsp3.

So I plug in my camera (ImagingSource DFK 21BF04.H) with a 6pin FireWire connector to the industrial computer which has a 9pin FireWire connector and i cant get more.

 then 100Mbit/s in MAX and also not in Vision Buildera AI 2009 SP1.

Download the Basler Pylon camera drivers and install them.  You don't need to install the SDK and other stuff, just the drivers.  I am pretty sure this will correct your speed issues.

I don`t know why Basler drivers would help, but I tried it and they don`t.

Also I have a ImagingSource USB camera that has a speed of 150 fps acording to the datasheet, but I can only change the picture format and not the speed that can only be 30 fps.

In MAX I can`t even change drivers for USB camera. There is no driver menu when right-clicking.

Cameras, bus or drivers ?

When you do not get the 400Mbs the problem looks like XP. I Thought it was solved in windows7

Problem speed off IEEE-1394 when using XP SP2:

After you update your computer to Microsoft Windows XP Service Pack 2 (SP2),

the performance of your 1394a or 1394b FireWire devices may be greatly decreased.

A digital camera that uses S400 speed is an example of such a device.

We use AVT camera's and PCI-express and AVT driver to do this. But we do not use Windows7 only XP

But i am not sure it will work with your camera.

NI somewhere had a prosilica patch

Hope this will help you.

The WinXP SP1 rollback 1394 patch should do the trick, it worked for us...

The solution from this link http://support.microsoft.com/kb/885222 will work,

not the exe, but manual registry edititng.

After edit registry you will be able to acheive 400Mbit/s maxumim. If you want to acheive 800 you should rollback the drivers from SP1 as LabUseful wrpte.
