Turned on KCC, logged in, started "Run" as soon as desktop came up, before akamai loaded completely, as I often do to get things started early.

VxWorks dialog again scrolled thru on the akamai window, monitor came up with the correct gui and barrel scanned from 359 to 176.

Set up scope on access points on signal transformation board (J6) to look at pulses between the counter/controller in the KCC and the tranceivers in the STM box on the spar. If the barrel doesn't run in the morning, I'd like to see if the KCC is still trying to send pulses up to the barrel. If it is, the problem may be upstairs in the electronics or the barrel may be in need of lubrication in its bearings. If there are no pulses, then the problem may be in the electronics downstairs or in the transfer of the VxWorks or in nahenahe's software. ___end___ **MKIV PROBLEM**: Thu Jul 27 02:41:10 GMT 2006 So far, I haven't found any consistent procedure or comments that point to a solution in the barrel problem written in the logs. ___end___ Thu Jul 27 02:43:04 GMT 2006 MkIV 00_01.rawmk4 01_40.rawmk4 18_25.rawmk4 20_05.rawmk4 21_57.rawmk4 00_04.rawmk4 01_43.rawmk4 18_28.rawmk4 20_08.rawmk4 22_00.rawmk4 00_07.rawmk4 01_46.rawmk4 18_31.rawmk4 20_11.rawmk4 22_02.rawmk4 00_10.rawmk4 01_49.rawmk4 18_34.rawmk4 20_14.rawmk4 22_05.rawmk4 00_13.rawmk4 01_52.rawmk4 18_37.rawmk4 20_17.rawmk4 22_08.rawmk4 00_16.rawmk4 01_55.rawmk4 18_40.rawmk4 20_20.rawmk4 22_11.rawmk4 00_19.rawmk4 01_58.rawmk4 18_43.rawmk4 20_23.rawmk4 22_14.rawmk4 00_22.rawmk4 02_01.rawmk4 18_45.rawmk4 20_26.rawmk4 22_17.rawmk4 00_25.rawmk4 02_04.rawmk4 18_48.rawmk4 20_29.rawmk4 22_20.rawmk4 00_31.rawmk4 02_07.rawmk4 18_51.rawmk4 20_32.rawmk4 22_23.rawmk4 00_34.rawmk4 02_10.rawmk4 18_54.rawmk4 20_35.rawmk4 22_26.rawmk4 00_37.rawmk4 02_13.rawmk4 18_57.rawmk4 20_38.rawmk4 22_29.rawmk4 00_40.rawmk4 02_16.rawmk4 19_00.rawmk4 20_40.rawmk4 22_32.rawmk4 00_43.rawmk4 02_19.rawmk4 19_03.rawmk4 20_51.rawmk4 22_35.rawmk4 00_46.rawmk4 02_22.rawmk4 19_06.rawmk4 20_54.rawmk4 22_38.rawmk4 00_49.rawmk4 02_25.rawmk4 19_09.rawmk4 21_07.rawmk4 22_41.rawmk4 00_52.rawmk4 02_27.rawmk4 19_12.rawmk4 21_10.rawmk4 22_44.rawmk4 00_55.rawmk4 17_26.rawmk4 19_15.rawmk4 21_13.rawmk4 22_47.rawmk4 00_58.rawmk4 17_29.rawmk4 19_18.rawmk4 21_16.rawmk4 22_49.rawmk4 01_01.rawmk4 17_32.rawmk4 19_21.rawmk4 21_18.rawmk4 22_52.rawmk4 01_04.rawmk4 17_34.rawmk4 19_24.rawmk4 21_21.rawmk4 22_55.rawmk4 01_07.rawmk4 17_37.rawmk4 19_27.rawmk4 21_24.rawmk4 23_19.rawmk4 01_10.rawmk4 17_40.rawmk4 19_30.rawmk4 21_27.rawmk4 23_23.rawmk4 01_13.rawmk4 17_43.rawmk4 19_32.rawmk4 21_30.rawmk4 23_44.rawmk4 01_16.rawmk4 17_46.rawmk4 19_35.rawmk4 21_33.rawmk4 23_47.rawmk4 01_19.rawmk4 17_49.rawmk4 19_45.rawmk4 21_36.rawmk4 23_50.rawmk4 01_22.rawmk4 17_52.rawmk4 19_48.rawmk4 21_39.rawmk4 23_53.rawmk4 01_24.rawmk4 18_06.rawmk4 19_51.rawmk4 21_42.rawmk4 23_56.rawmk4 01_27.rawmk4 18_13.rawmk4 19_53.rawmk4 21_45.rawmk4 23_58.rawmk4 01_30.rawmk4 18_16.rawmk4 19_56.rawmk4 21_48.rawmk4 c17_55.rawmk4 01_34.rawmk4 18_19.rawmk4 19_59.rawmk4 21_51.rawmk4 c18_03.rawmk4 01_37.rawmk4 18_22.rawmk4 20_02.rawmk4 21_54.rawmk4 c18_10.rawmk4
