Acquire Synchronized Data Using PXIe Devices

Hi, I have a problem with the Data Acquisition Toolbox when using session based interface.

I have a NI PXIe 1073 chassis and two NI PXIe 6356 DAQS, I am following the example: http://www.mathworks.com/help/daq/multiple-chassis-synchronization.html(Acquire Synchronized Data Using PXIe Devices).

when I get dataIn = s.startForeground();

an error comes out:

NI Error -89136: Specified route cannot be satisfied, because the hardware does not support it.

Property: DAQmx_RefClk_Src

Requested Value: /Dev1/PXI_CLK10

Task Name: _unnamedTask<64>

Status Code: -89136

The NI PXIe 1073 should support this as the back-plane already have PXI_CLK10. I also called the NI, they didn't provide a solution for this. As the NI technician suggested, when I using Labview to synchronize the two devices, there is no problem.

Anyone has a solution for this?

Best Wishes!

Hello Icheck following web site. This is for PXI sample not PXIExpess. http://jp.mathworks.com/help/daq/multiple-device-synchronization.html#burb_52-1

Could you tell me the code you wrote?

Thanks
