Known IssuesNI-IMAQ

• The NI PCIe-1433 or NI PXIe-1435 may lose the first image of a triggered acquisition if the attached camera is in a triggered mode that does not drive the line valid signal while waiting.

• The NI-IMAQ .NET API is not supported on the NI PCI-1408.

• When you upgrade from NI Vision Acquisition Software 8.0, .NET support and examples are not installed. To install .NET support, uninstall NI Vision Acquisition Software 8.0 and install a later version NI Vision Acquisition Software. If you already have a later version of NI Vision Acquisition Software installed, you must repair the installation to add .NET support and examples.
  

NI-IMAQdx

• When you upgrade from NI Vision Acquisition Software 8.0, the .NET support and examples are not installed. To install support for .NET, uninstall NI Vision Acquisition Software 8.0, and then install a later version NI Vision Acquisition Software. If you already have a later version of NI Vision Acquisition Software installed, you must repair the installation to add .NET support and examples.

• Plugging a device into an IEEE 1394 bus causes a bus reset. If there are any ongoing acquisitions, the acquisition continues, but it is possible that a frame could be dropped. If you have an application in which it is important to get every frame, you should protect against devices being plugged into the bus.

• Windows OS Issues
  

• Updating your computer to Windows XP Service Pack 2 may decrease the performance of your IEEE 1394 devices running with an IEEE 1394b host interface, such as the NI PCIe-8255R. Refer to the NI KnowledgeBase article 3J0A446W or Microsoft Knowledge Base article 885222 for more information.

• When switching drivers, you may find that the camera does not always appear in the MAX configuration or in your Device Manager. To correct this, disconnect the IEEE 1394 camera from your IEEE 1394 adapter and reconnect it. You can also press the <F5> key to refresh.
  

• Using Multiple Cameras
  

• The IIDC 1394-based Digital Camera Specification version 1.30 allows up to 16 cameras and one controller to exist on an IEEE 1394 bus at one time. Multiple cameras connected to a single adapter share the same IEEE 1394 bus and the available bandwidth for that bus. To simultaneously acquire images from multiple cameras, select a video mode for each camera so that the total bandwidth does not exceed the bandwidth capability of the bus.
  

  Note: NI-IMAQdx returns an Insufficient Resources error if you perform an acquisition that requires more bandwidth than is available on the bus.
  To use multiple cameras simultaneously at full speed, connect each camera to a separate IEEE 1394 adapter. You cannot simultaneously acquire images at maximum bandwidth from multiple cameras when all cameras are connected to the same bus.

  
  

NI-IMAQ I/O

• In LabVIEW 8.6, the Abort and Reset FPGA Interface methods will not execute if there is an error coming into the node. As a work around, route the error around the method nodes. Close and Reset if Last Reference executes as expected.

• When you upgrade from NI Vision Acquisition Software 8.0, the .NET support and examples are not installed. To install support for .NET, uninstall NI Vision Acquisition Software 8.0, and then install a later version NI Vision Acquisition Software. If you already have a later version of NI Vision Acquisition Software installed, you must repair the installation to add .NET support and examples.

• When creating LabVIEW FPGA applications for NI-IMAQ I/O devices, the digital inputs ISO_POWER_PRESENT and USER_DIP are low true signals. Also, digital outputs should be treated as outputs only. Trying to use an output on your device as a digital output and a digital input in your LabVIEW FPGA block diagram will result in a compilation error.

• Configuring the shutdown states on an NI-IMAQ I/O device while the default personality is running on the FPGA can affect the value of the isolated output lines. Drive the isolated outputs with the value you expect after configuring shutdown states.

• If you need to call multiple instances of the Open FPGA VI Reference function, National Instruments recommends running them sequentially and not simultaneously.

• The host VI might import improperly to LabVIEW 8.2 or later if any of the following conditions apply: you use constants for the HW Exec Ref parameter on the block diagram, you use Call By Reference Nodes that pass the HW Exec Ref parameter, or you use strict type definitions of the HW Exec Ref parameter with property nodes to get or set their value. Open the host VI and manually replace all instances of the HW Exec Ref that are broken with the new HW Exec Ref coming from the Open FPGA VI Reference function.

• A host VI created with the LabVIEW FPGA Module 1.x might have used the Abort method with an Invoke Method function or as part of the Close FPGA VI Reference function. The import utility replaces the Abort method with the Reset method. The Abort method in the LabVIEW FPGA Module 1.x resets the FPGA VI to default values. The Reset method in the LabVIEW FPGA Module 8.2 resets the FPGA VI to default values. In the LabVIEW FPGA Module 8.2, the Abort method stops the FPGA VI but does not reset the values to their default values. By replacing the Abort method with the Reset method, the import utility preserves behavior of your program. No action on your part is necessary.

• Pop-up windows are not supported in executables running on Real-Time (RT) targets. Therefore, no window pops up to indicate when an FPGA VI is programmatically downloaded by a host VI running on an RT target.

• Host VIs that contain the FPGA Interface functions might take a long time to open because the FPGA Interface functions need several support files to manage the interface with FPGA VIs. The FPGA Interface functions also verify the status of the FPGA VI when you open the host VI.

• When adding an existing IMAQIO-5 FPGA target in LabVIEW 8.0 with the LabVIEW FPGA Module 8.0, the IMAQIO-5 FPGA target will not appear in the Add Targets and Devices configuration tree, and <No Items Found> is displayed in the configuration tree. Refer to National Instruments KnowledgeBase 3UGCL2D3 for instructions to correct this issue. To determine which FPGA your device uses, refer to the LabVIEW Help and search for NI-IMAQ I/O Reference.
