ScanImage 2019 : Power Control Only Works with "Direct Mode" Checked

For some reasons, power control panel does not work when "direct mode" is NOT checked: for example there is no effect on pockels cell output by power level slider.

However, the slide did change power when "direct mode" is checked.


The most common reason for this is that the Beams device is not assigned to ResScan correctly, in the machine data file (MDF).

Check your Machine Data File:

%% Beams
beamDaqDevices = {'PXI1Slot4'};   % <- let's say you have one DAQ device for beams

%% ResScan
beamDaqID = 1;                             % <- assign that DAQ device to be used with ResScan
