How do I get the information of each device (including device families, device type,device name, physical channel numbers etc.) by using DAQmx functions, if multi-devices are installed. Thereby, I can select different devices to accomplish data acquisition by using the same test program. The devices are two PCI-6014, PCI-4472, PCI-MIO-16E-4,PCI-4551. DAQmx don't support PCI-4551. If you have some solutions, please give me Email. Thank you every much. My Email: yjhyan@hotmail.com.
