Configuring the IMAQ 1426
After you have installed the IMAQ 1426 and powered on your computer,
Windows will recognize the device and assign resources to it. Use
National Instruments Measurement & Automation Explorer (MAX) to
configure the IMAQ 1426 for acquisition.
Interfacing with the IMAQ 1426
The Camera Link standard defines physical connections between image
acquisition devices and Camera Link cameras, and it allows for flexibility
of image format and data transfer protocols. The camera manufacturer
defines image parameters, such as image resolution and the number of bits
per pixel. Camera control parameters, such as frame-on-demand and
exposure control signals, are also defined by the camera manufacturer.
These variable parameters are defined on a per-camera basis in a camera
file (
camera_model.icd
) supplied by National Instruments. The
NI-IMAQ driver software uses the information in this camera file to
program the IMAQ 1426 to acquire images from a specific camera. Without
this camera file, the driver does not have the information necessary to
configure the IMAQ 1426 for acquisition.
MAX, the National Instruments configuration utility, provides a simple
interface for associating a camera file with the IMAQ 1426. Use the
following guidelines to access the camera file in MAX:
1.
Launch MAX, and expand the
Devices and Interfaces
branch of the
configuration tree.
2.
Expand the
NI-IMAQ Devices
branch.
3.
Expand the
IMAQ PCI-1426
branch.
4.
Right-click
Channel 0
and select
Camera
.
5.
Select your camera from the menu. If your camera is not in the menu,
verify that the camera file is installed in the
NI-IMAQ\Data
directory.
