Command Node

Call MvCamCtrl.NET::MyCamera::MV_CC_GetStringValue_NET /

MvCamCtrl.NET::MyCamera::MV_CC_SetStringValue_NET

Call MvCamCtrl.NET::MyCamera::MV_CC_SetCommandValue_NET

Note

• You can get and set the acquisition mode including single frame acquisition, multi-frame

acquisition, and continuous acquisition via the API

MvCamCtrl.NET::MyCamera::MV_CC_GetEnumValue_NET (handle, "AcquisitionMode",

&stEnumValue) and MvCamCtrl.NET::MyCamera::MV_CC_SetEnumValue_NET (handle,

"AcquisitionMode", value).

• You can set triggering parameters.

a. Call MvCamCtrl.NET::MyCamera::MV_CC_SetEnumValue_NET (handle, "TriggerMode",

value) to set the triggering mode.

b. If the triggering mode is enabled, call

MvCamCtrl.NET::MyCamera::MV_CC_SetEnumValue_NET (handle, "TriggerSource",

value) to set the triggering resource. The triggering source includes triggered by hardware

and software.

c. Call MvCamCtrl.NET::MyCamera::MV_CC_GetFloatValue_NET (handle, " TriggerDelay",

&stFloatValue) and MvCamCtrl.NET::MyCamera::MV_CC_SetFloatValue_NET (handle, "

TriggerDelay", value) to get and set the triggering delay time.

d. When triggered by software, call

MvCamCtrl.NET::MyCamera::MV_CC_SetCommandValue_NET (handle, "TriggerSoftware

") to capture; when triggered by hardware, capture by device local input.

• You can set the image parameters, including image width/height, pixel format, frame rate,

AIO offset, gain, exposure mode, exposure value, brightness, sharpness, saturation, grayscale,

white balance, Gamma value, and so on, by calling the following APIs:

MvCamCtrl.NET::MyCamera::MV_CC_SetIntValueEx_NET ,

MvCamCtrl.NET::MyCamera::MV_CC_SetEnumValue_NET ,

MvCamCtrl.NET::MyCamera::MV_CC_SetFloatValue_NET ,

MvCamCtrl.NET::MyCamera::MV_CC_SetBoolValue_NET ,

MvCamCtrl.NET::MyCamera::MV_CC_SetStringValue_NET ,

MvCamCtrl.NET::MyCamera::MV_CC_SetCommandValue_NET .

5. Call MvCamCtrl.NET::MyCamera::MV_CC_StartGrabbing_NET to start getting streams.

Note

• Before starting the acquisition, you can call

MvCamCtrl.NET::MyCamera::MV_CC_SetImageNodeNum_NET to set the number of image
