Acquire Image (IEEE 1394 or GigE) FAQs
In the Acquire Images tab, why is the Acquire Image (IEEE 1394 or GigE) icon disabled?
The icon may be disabled for several reasons. Verify that the correct version of the NI-IMAQdx driver software is installed. If necessary, install the driver software. If the icon is still disabled after verifying that the correct driver is installed, refer to the Measurement & Automation Explorer Help for NI-IMAQdx for troubleshooting tips. You can access the Measurement & Automation Explorer Help for NI-IMAQdx in MAX by clicking Help»Help Topics»NI-IMAQdx.
My camera appears in Measurement & Automation Explorer (MAX) but does not appear in the Devices list. How can I get the name of my camera to appear in the Devices list?
Make sure that the camera is associated with the NI-IMAQdx driver in MAX. If the camera is listed under Legacy NI-IMAQ IEEE 1394 Devices, right-click the camera and select Driver»NI-IMAQdx IIDC Digital Camera. Refer to the Measurement & Automation Explorer Help for NI-IMAQdx for troubleshooting tips.

Why does my 16-bit image appear incorrectly?
Complete the following steps to adjust the 16-bit pixel representation parameters and correct the image:
- In the property page for the Acquire Image (IEEE 1394 or GigE) step, on the Main tab, select the camera from the Devices list.
- Click the Attributes tab.
- Select the Show All Attributes checkbox to list all of the attributes for the camera.
- Adjust the values for the BitsPerPixel, ShiftPixelBits, and SwapPixelBytes attributes to correct the image.
- Click OK to save the configuration settings.

Note Some image processing algorithms do not support 16-bit images. |
Why do some attributes not have an effect on the image?
Even though an attribute is writable, the camera may be in a mode that ignores the attribute you are trying to set. For example, if the camera is in an 8-bit mode and you set the BitsPerPixel or ShiftPixelBits attribute, the image will not be affected because those attributes only apply to 16-bit images.
Why are no triggering modes listed in the Attribute tree?
Not all cameras support triggering. Only attributes supported by the camera are listed in the Attribute tree.
