*************Feedback Set Up On Front End Computer*************

This shouldn't  be fiddled with!!!, but here's what's currently done.

On bl831b.als.lbl.gov, the front-end computer (accessible from KVM switch near "graphics1") 
confirm that the Video Feedback Control is ON and setup properly.

From the  "Motors" drop down-menu, Open the "Motor Debug" Window, and check that
 "Horizontal Video Control" is Enabled
 "Vertical Video Control" is Enabled.

From the "Video" drop-down-menu, select "Monitor" check that:
Average Factor = 0.00
Black Reference = 0.315
View = Filtered
Threshold = 40
White Reference = 0.9

Confirm that the ROI is set to a proper size.

The feedback can also be checked, turned on, and off with a script from a graphics machine:
feedback.com [keep, off]
