A class to handle the digital inputs and outputs for frame grabber devices(Device specific interface layout only) (deprecated.
This class provides a convenient basic access to the digital inputs and outputs of a frame grabber device.
To create more complex digital output related signals the class mvIMPACT.acquire.OutputSignalGeneratorFrameGrabber should be used.
__init__ | ( | self, | |
* | pDev, | ||
** | kwargs ) |
Constructs a new mvIMPACT.acquire.IOSubSystemCommon object.
pDev | [in] A pointer to a mvIMPACT.acquire.Device object obtained from a mvIMPACT.acquire.DeviceManager object. |
Reimplemented from IOSubSystemCommon.
getHDOutputCount | ( | self | ) |
Returns the number of available HD output pins for the mvIMPACT.acquire.Device associated with this object.
getVDOutputCount | ( | self | ) |
Returns the number of available VD output pins for the mvIMPACT.acquire.Device associated with this object.
HDOutput | ( | self, | |
nr ) |
Returns a pointer to a mvIMPACT.acquire.SyncOutput object that represents a HD output for this device.
nr MUST be a valid number ( larger or equal than 0 and smaller than the value returned by mvIMPACT.acquire.IOSubSystemFrameGrabber.getHDOutputCount.
nr | [in] The number of the HD output to return. |
VDOutput | ( | self, | |
nr ) |
Returns a pointer to a mvIMPACT.acquire.SyncOutput object that represents a VD output for this device.
nr MUST be a valid number ( larger or equal than 0 and smaller than the value returned by mvIMPACT.acquire.IOSubSystemFrameGrabber.getVDOutputCount.
nr | [in] The number of the VD output to return. |

An enumerated integer property defining the current mode for sync.
signal creation.
Sometimes it's desired to create a signal to sync. cameras connected to a capture device. E.g. when capturing 3 monochrome cameras in parallel these should be synchronized. Therefore some devices can create HD and VD signals that synchronize the connected cameras.
To create sync. signals this property must be set either to mvIMPACT.acquire.dsomNonInterlaced or mvIMPACT.acquire.dsomInterlaced.
In interlaced mode only the frequency of the VD signals can be modified, while in non-interlaced mode the width (in percent) the signal stays low can be modified as well.
Now e.g. to sync. two or more CCIR compliant cameras connected to a capture device that can create sync. signals, the HD signals must be generated with a CCIR compliant frequency. The function mvIMPACT.acquire.IOSubSystemFrameGrabber.HDOutput can be used to access the desired output pin. Then its property mvIMPACT.acquire.SyncOutput.frequency_Hz is set to 15625 Hz (CCIR standard). The remaining values can be left untouched. The capture device will no generate HD signals with the desired frequency and VD outputs with the frequency stored by the property mvIMPACT.acquire.SyncOutput.frequency_Hz belonging to the pointer to the object returned by a call to mvIMPACT.acquire.IOSubSystemFrameGrabber.VDOutput.
