Number of Ports

Number of Ports

Returns the number of ports that an image acquisition device supports.

Note  A port identifies a single independent data stream from a camera. All NI image acquisition devices support at least one port. Devices that support multiple ports can sustain independent and asynchronous acquisitions from the cameras on each port.
