Not sure how some were changed, but found analog and digital gains changed, such that the camera on PMC trans was not reading a beam, and the straight through camera on the bottom periscope mirror was not reading a beam.  Analgo gains are restored to 1 on all 3 cameras (text file, reload config), IOGigE1 (cam28), IOGigE2 (cam29), IOGigE3 (cam09).  Digital gains set as in the attached snapshot.
