Hi all!
I am working at the com port in order to control the optical shutter (SC10; Thorlabs) using MATLAB. While I could control it, I am looking for the way to read the optical shutter status (open or closed). There is a command 'closed?' to do this but MATLAB does not return the correct value. My code is like,,
s=serial('COM1');
s.Terminator='CR';
fopen(s);
fprintf(s,'ens');
fprintf(s,'closed?');
Ret=fscanf(s)
It would be greatly appreciated if I could get any input!
Thanks,
Kang

Dear Sir,
Could you provide the MatLab script to operate the shutter: opens for 200 mili second in every 10 seconds for 3 times.
Thank you.
Regards

You have two "fprintf" calls in the code and one "fscanf". The "fscanf" will return the result of "ens". For "closed?" execute "fscanf" one more time.
