I am trying to use all four channels of a NI 9775 DAQ but I keep getting error code 200106 when I try to use addAnalogInputChannel() for more than one channel. Here is my code:
s = daq.createSession('ni'); % Create session
Fs = 5000000; % Sampling freq.
s.Rate = Fs; % Set sampling rate
s.addAnalogInputChannel('cDAQ1Mod1', 0:3, 'Voltage');
%ch0.ADCTimingMode = 'HighSpeed';
%ch0.Name = 'CH_0';
%ch1 = addAnalogInputChannel(s, 'cDAQ1Mod1', 1, 'Voltage');% Initialze chan. 1
%ch1.ADCTimingMode = 'HighResolution';
and here is the error in the command window:
Warning: A channel that does not support on-demand operations was added to the session. On-demand operations using inputSingleScan
and outputSingleScan will be disabled. Only clocked operations using startForeground and startBackground can be done.
Warning: ADCTimingMode property reset to the default value: 'HighResolution'.
Error using XY_DAQ_Test (line 19)
NI Error -200106:
Property must have the same value for all channels on this device.
Property: DAQmx_AI_ADCTimingMode
Corresponding Value: DAQmx_Val_HighResolution
Channel Name: cDAQ1Mod1/ai1
Task Name: _unnamedTask<30D>
Status Code: -200106
So far as I can tell, all the channels are set to the default ADC Timing mode, which is high resolution. I have also tried manually setting the timing mode to high resolution and high speed without success. What am I doing wrong?

Dear Alex,
I'm experiencing the same issue as you.
Have you found a work around this problem?
BR, Csaba
Edit : This might work for you too. Edit as admin the file in "C:\Program Files\MATLAB\R2020a\toolbox\daq\daq\+daq\+ni" by adding "NI 9775" as exception that should not taken into account.

As of MATLAB R2020a, the NI 9775 module is not supported and tested yet with Data Acquisition Toolbox. Support is considered for a future release.
Please refer to the hardware support page for NI-DAQmx devices: https://www.mathworks.com/hardware-support/nidaqmx.html

Dear all,
Is there any update forseen to get a multichannel acquisition ?
