Synchronizing X Series, M Series, SC Express, and NI mioDAQ Devices
Note To synchronize analog input tasks on multiple X Series and SC Express devices at the same sampling rate, you can use channels from those devices within the same task.
X Series, M Series, SC Express, and NI mioDAQ devices support the following synchronization methods:
- Start Trigger synchronization
- Reference Clock synchronization
- Sample Clock synchronization
Refer to the Device Routes tab in MAX to determine which PXI and RTSI lines can route synchronization signals.
Note You cannot use a RTSI cable to connect multiple USB X Series devices.
Note The NI 4302/4303/4304/4305, NI 4330/4331, and NI 4339 only support exporting their sample clock. They do not support importing a sample clock.
Note The NI 4340 supports importing a sample clock only in hardware-timed single-point sample mode.
