IMAQdx Open Camera VI
Installed With: NI Vision Acquisition SoftwareOpens a camera, queries the camera for its capabilities, loads a camera configuration file, and creates a unique reference to the camera. Use the IMAQdx Close Camera VI when you are finished with the reference.

Camera Control Mode is the control mode of the camera used during image broadcasting. Open a camera in controller mode to actively configure and acquire image data. Open a camera in listener mode to passively acquire image data from a session that was opened in controller mode on a different host or target computer. The default value is Controller. |
||||||
 |
Session In specifies the name of the camera you wish to open. The default value is cam0. |

 |
error in describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. Explain Error (or Explain Warning) gives more information about the error displayed.

 |
Session Out is a unique reference to the camera. Session Out is the same as Session In. |
||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI produces. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
