After successfully configuring a Windows system to use an USB-1408FS-Plus module with MATLAB R2017a (reference KB article - http://kb.mccdaq.com/KnowledgebaseArticle50721.aspx), the following lines were used in a .m script to output single voltage values via the analog output channel.
% Create analog output session
s = daq.createSession('mcc');
% Add an analog output channel from device ID (Board0) and channel ID (Ao0),
% with the measurement type to 'Voltage'.
ch0 = addAnalogOutputChannel(s,'Board0', 'Ao0', 'Voltage');
% Set voltage level for analog output channel to step from 0 to 5 volts
for i=0:5
aout = i;
outputSingleScan(s, aout);
pause(1);
end
% Reset voltage output level
aout = 0;
outputSingleScan(s, aout);
%% Cleanup
delete (s);
