Issue Details

I have a Camera Link camera connected to an NI Frame Grabber. I need to be able to configure my camera using the serial port built-in to the Camera Link connection, but I do not see the serial port enumerated as a COM port. How can I send commands to my camera over serial?

Solution

NI Camera Link Frame Grabbers give you access to the serial port on a connected Camera Link camera, but this port does not enumerate as a standard COM port. To send a serial command to your camera, you can use one of the following methods:
  • Use the IMAQ Serial VIs in LabVIEW
The NI-IMAQ driver includes VIs for communicating with your camera over serial. Use IMAQ Serial Write.vi to write commands to the camera and IMAQ Serial Read.vi to read the camera's response. The following example shows how to do this:
  • Use the NI Camera File Generator
The NI Camera File Generator is used to create or edit camera files, which define the interaction between NI software, the frame grabber, and your camera. This tool also allows you to send and receive serial data from your camera. For more information, refer to the the following KnowledgeBase article:

  • Use the third-party configuration tool from your camera's manufacturer
Many camera manufacturers have a configuration tool (such as Basler Pylon) that can be used to configure the settings for your camera, even if it is being used with an NI frame grabber.
