niVMS Initialise VI

niVMS Initialise VI

Initialises NI VMS by reading all configuration files and verifying licensed software features.  You call this VI before any other in the API.  The license file must already be installed in the <install path>\Bin directory.  The configuration files read by this VI are all located in the <install path>\Config directory, and include the following information:

• CVBS Standards—defines the properties of composite and S-Video signals required for acquisition and analysis.
• CAV Standards—defines the properties of Component video signals required for acquisition and analysis.
• VGA Standards—defines the properties of computer VGA video signals required for acquisition and analysis.
• Video Hardware—defines the selection and configuration of video acquisition hardware devices.
• Camera Zones—defines several zones within the active picture region that may be used for certain types of camera measurements.

	Error In describes error conditions that occur before this node runs. This input provides standard error in functionality.
	Available Standards contains lists of all available standards of the three different video signal types. CVBS returns an array of the names of all available CVBS video standards. CAV returns an array of the names of all available CAV video standards. VGA returns an array of the names of all available VGA video standards.
	Configuration File Paths contains the paths of all three video standards configuration files. CVBS Standards returns the path of the CVBS video standards file. CAV Standards returns the path of the CAV video standards file. VGA Standards returns the path of the VGA video standards file. Camera Zones returns the path of the camera zones configuration file. Hardware returns the path of the video hardware configuration file.
	Licensed Features indicates all enabled software and hardware features. Demo returns reserved and is currently not used. Composite returns TRUE if composite video acquisition and analysis are enabled. S-Video returns TRUE if S-Video video acquisition and analysis are enabled. Component returns TRUE if component video acquisition and analysis are enabled. MPEG returns TRUE if MPEG analysis is enabled. This feature is not currently supported. On-Line returns TRUE if the use of hardware is enabled. This parameter returns FALSE if hardware is offline). Camera returns TRUE if CCD camera measurements are enabled. VBI returns TRUE if vertical blanking information (VBI) measurements are enabled. Macrovision returns TRUE if Macrovision measurements are enabled. Instruware is always enabled. TestStand returns TRUE if NI TestStand support is enabled. Digital returns TRUE if digital acquisition is enabled.
	Error Out contains error information. This output provides standard error out functionality.
