Use DO and AI function in one DAQ Device

[a710756]

Hi, everyone

I try to use DO and AI function in DAQ USB-6008.

When I run my program it shows one error message as below,

Please suggest me how to solve this problem?

Thank you!

 

My Code:

DAQmxCreateTask("", &gTaskHandle_DAQ1);

DAQmxCreateTask("", &gTaskHandle_DAQ1_DO);

DAQmxCreateAIVoltageChan(gTaskHandle_DAQ1, cChan_DAQ1, "", DAQmx_Val_Cfg_Default, min,max, DAQmx_Val_Volts, NULL);

DAQmxCfgSampClkTiming(gTaskHandle_DAQ1, "", rate, DAQmx_Val_Rising, DAQmx_Val_ContSamps, sampsPerChan);

DAQmxGetTaskAttribute(gTaskHandle_DAQ1, DAQmx_Task_NumChans, &gNumChannels);

DAQmxCreateDOChan(gTaskHandle_DAQ1_DO, cChan_DAQ1_DO, "", DAQmx_Val_ChanForAllLines);  <--- Occur error

Sorry, add below.

Can you try all AI & DO functions on Measurement and Automation Explorer>>Test Panel?

or Can you update your NI-DAQmx driver to 8.6.1?

or may be you need to RMA.
