I connected PZT1 and PZT2 to a slow front end machine c1iscaux.
Now we are able to align these PZTs from the control room via epics.
Since we removed C1ASC that was controlling the voltage applied on the PZTs, we didn't have the controls for them for a long time.
So Rana and I decided to hook them up to an existing slow front end machine temporarily.
(probably the best solution is to connect them to C1LSC, which is fast enough to dither them.)
We actually found that c1iscaux is the proper machine, because it looked like it used to control the PZTs a long long time ago.
Moreover, c1iscaux still has DAC channels named like C1:LSC-PZT1_X, and so on.
Below shows a screen shot of the medm screen for controlling the PZTs, invoked from a button on sitemap.adl ( pointed by a black arrow in the picture below)
The current default values are all zero at the right top sliders.
