DSA

A task can include channels from multiple DSA devices, given the following conditions. When you include channels from multiple DSA devices in a task, NI-DAQmx automatically synchronizes the devices.

All Devices

• All channels in the task must be analog input channels.
• If the task includes channels from both 446X and 447X devices, you must account for filter delay differences between the devices.

PXI Devices

• The devices must all be in a single chassis, and you must identify the chassis in MAX.
• If the task includes channels from 447X devices, one of the devices must be in PXI slot 2.
• If the task includes channels from both 446X and 447X devices, a 446X device must be in PXI slot 2.

PCI Devices

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