A task can include channels from multiple DSA, SC Express, and X Series devices, given the following conditions. When you include channels from multiple devices in a task, NI-DAQmx automatically synchronizes the devices and enables trigger skew correction for the devices. All channels in a task must be of the same I/O type, such as analog input or analog output.

Note Note   For additional device-specific DSA synchronization information, refer to the NI Dynamic Signal Acquisition User Manual, which you can find at ni.com/manuals.
Related information

Analog Input

  • USB X Series Devices

    You cannot use USB X Series devices in multidevice tasks.

  • PCIe X Series Devices

    You must use a RTSI cable to connect the devices, and you must identify the cable in MAX.

  • PXI/PXIe Devices
    • The devices must be in a single chassis, and you must identify the chassis in MAX.
    • NI-DAQmx accounts for filter delay differences between devices with some qualifications:
      • NI 4461 and 4462 devices lack the ability to compensate for filter delay.
      • For all other devices, if the task includes channels from different device families, NI-DAQmx will account for filter delay differences between the devices.

Use the following table to check the multidevice task compatibility of any one device to another device. A checkmark in a cell indicates that the devices in the corresponding row and column can be used together in a multidevice task. For groups of more than two devices, every device must be compatible with every other device. An example of a group of devices that can be used in a multidevice task is the NI 4300, 4353, 4357 and PXIe X Series (63xx) as all of these devices are compatible with every other device listed in the group.

Analog Output

  • PXIe-4463 devices

    The devices must be in a single chassis and the chassis must be identified in MAX. All devices in the task must be PXIe-4463s.
