Tried changing 24 vdc on spar power supply for barrel from PS1 to PS2 (white power supply boxes above spar junction with pier up in main dome) to see if this would improve anything because it did improve a problem with some similar symptoms back in April 2003, but it didn't change anything, we still have the barrel running CCW until CCW limit at 274 with no apparent data shown on realtime scan GUI with old MV200 video card in place, and we still have sectored concentric ring looking scans with slow down scanning rates sometimes but a continuously scanning barrel with the spare MV200 board in place. Switched PS1 and PS2 outputs back to normal. Tried connecting a computer video monitor to the output jacks on each MV200 card, saw a 0.5"x3.0" horizontal rectangle of mostly white and one column of checkerboard-like pattern of rectangles at far right of screen when using spare MV200 board in place and scanning or with barrel still, with the old mv200 board in place I saw a checkerboard-like pattern of different shaded rectangles over the entire monitor whether scanning or with barrel still. Not sure why the output was different between the boards, or if the output was the "modulation states" David mentioned, I'll ask him. Old MV200 board is in place. Will continue searching for similar past problems next time. ___end___ Wed Apr 29 22:42:31 GMT 2009 CHIP End Patrol Wed Apr 29 22:42:59 GMT 2009 PICS End Patrol Wed Apr 29 22:53:16 GMT 2009 MKIV Start Patrol Wed Apr 29 23:27:31 GMT 2009 MKIV End Patrol Wed Apr 29 23:39:03 GMT 2009 MkIV 20_54.rawmk4 21_12.rawmk4 21_45.rawmk4 22_15.rawmk4 23_11.rawmk4 20_55.rawmk4 21_13.rawmk4 21_51.rawmk4 22_53.rawmk4 23_17.rawmk4 20_56.rawmk4 21_20.rawmk4 21_53.rawmk4 22_54.rawmk4 23_19.rawmk4 21_02.rawmk4 21_37.rawmk4 21_59.rawmk4 22_55.rawmk4 23_25.rawmk4 21_04.rawmk4 21_40.rawmk4 22_01.rawmk4 23_02.rawmk4 21_06.rawmk4 21_42.rawmk4 22_07.rawmk4 23_03.rawmk4 21_09.rawmk4 21_43.rawmk4 22_09.rawmk4 23_09.rawmk4
