Start Conditions

The NI PCIe-1437 can start acquisitions in the following ways:
  • Software control—The device supports software control of acquisition start. You can configure the device to capture a fixed number of frames. Use this configuration for capturing a single frame or a sequence of frames.
  • Trigger control—You can start an acquisition by enabling external TTL, RTSI, or isolated input lines. Each of these inputs can start a video acquisition on a rising edge or a falling edge.
