S Series Multidevice Tasks

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

All Devices

All channels in the task must be analog input channels.

When you include channels from different S Series devices and use an external clock setup, you must import the external clock into the device with the longest pipeline of all the devices in the task. Failing to do so results in an incomplete acquisition, with the device importing the clock not receiving enough sample clock pulses.

PXI Devices

The devices must all be in a single chassis, and you must identify the chassis in MAX.

PCI Devices

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