Frame Burst Start (= Acquisition Start) = a series of images

The Frame Burst Start trigger and the Acquisition Start trigger are identical, only the names differ. The naming depends on your camera model. If available, you can use the Frame Burst Start, End, and Active triggers to control the acquisition of a series of images (a “burst” of images).

Frame Start = a single image

If available, you can use the Frame Start, End, and Active triggers to control the acquisition of a single image.

Trigger Mode

The Trigger Mode camera feature allows you to enable or disable triggered image acquisition for the trigger type selected. 当设置为Off，相机为free run模式，当设置为On时，只有满足触发条件才会拍照。

Trigger Source

可以设置软件或者硬件触发。

Trigger Activation

当为硬件触发时，设置为上升沿触发还是下降沿触发。

Line Source

  1. Frame Trigger Wait or Acquisition Trigger Wait, 高电平代表相机可以接受触发，低电平代码相机正忙碌，请不要触发拍照
  2. Exposure Active, 高电平代表正在曝光

Camera Power

You must supply camera power either via Power over Ethernet (PoE) or via the camera’s I/O connector. Do not use both ways of supplying camera power at the same time.

Single Shot

如果需要使用pylon Viewer拍照时，有两种模式可以触发拍照，Trigger Mode = On 或者 Trigger Mode = Off

Trigger Mode = Off

当Trigger Mode为off时，也就意味着不需要额外的触发模式就可以取图，此时只要点击工具栏的Single Shot按钮就会直接拍照并获取到图片。

Trigger Mode = On

当Trigger Mode为on时，此时如果点击工具栏的Single Shot按钮时不会拍照的，pylon Viewer会进入等待外部触发拍照模式，如果Trigger Source为Trigger Software，那么就是软件触发，如果Trigger Source为Line1, 那么就是硬件触发。一旦接收到软件或硬件触发信号，pylon Viewer就会拍照。
