Issue Details

I have a multidevice task in DAQmx (otherwise known as channel expansion), and I get error -201424 from DAQmx when I try to run my program.

Error -201242 occurred at an unidentified location
Possible reason(s):
The multidevice task cannot be synchronized in its current configuration.

Solution

One of the devices in your task is not compatible with one or more of the other devices. Take a look at the DAQmx help for multidevice tasks to see if your device cannot explicitly be in the same task as others. In particular, many DSA, SC Express, and X Series devices are not compatible with each other.

Additional Information

A multidevice tasks in DAQmx automatically sets up synchronization between the devices, without having to manually specify triggers, sample clocks, etc. Some devices are incompatible with each other in this configuration because the device routes needed for synchronization cannot be resolved.
