The HEPI overview screens were not displaying the ISI DAC outputs correctly. This was fixed on the HEPI overview screen template, and the update was ported here at LHO.
The update required to add the ISI_DAC macro substitution to the macro substitution text files of HEPI, which was done too. The new version of those files was committed to the svn -r7772
Details about the content of the update can be found in SEI aLOG #453
Work was performed under WP 4588, which can now be closed.
