New MPICaptureConfig Parameter Descriptions

  type

Specifies either postion-based or time-based capture. Use MPICaptureTypePOSITION for position-based capture and MPICaptureTypeTIME for time-based capture.

  captureMotorNumber

The number of the motor whose "source" (MPICaptureTrigger) is used to capture position.

  feedbackMotorNumber The number of the motor whose position is being returned from the capture event. (It must be the same as captureMotorNumber for position capture).
  encoder Specifies the encoder feedback being captured.
  captureIndex

A zero-based index that specifies which capture resource on an axis is to be associated with the capture object.

Each axis on a node has a given number of captures associated with it. Normally, each axis has only 1 capture resource, but an azis may have up to 4 capture resources.
