====== FAQ ====== ==== Lamps ==== **Q:** What do you have to consider after a //Standard Lamp// bulb change?\\ **A:** Ensure brightest part of the band of light is sitting in the middle of the Iris. There are two ways to accomplish this.++++ More...| - Manually adjusting by loosening the zenith shaft and moving the shaft until the band of light lines up as shown in the picture. \\ {{ :misc:misc:sl_band.png?600 |}} - Doing a ZI, this will do a shorten DI where it only checks for the zenith position.\\ {{:misc:zi.jpg?600|}} \\ As shown on the graph above, the zenith is -1 step off. Therefore the Offsets needs to be changed as follows. \\ * For MB electronics, the offset is clockwise from the reference, so the Zenith Offset: +1 I.E. Original: 100, New: 101\\ * For SB electronics the Zenith Motor origin moves counter clockwise so the Motor.Origin[1]: (gets smaller) Zenith Origin: -1 I.E. Original: 5, New: 4 \\ * UV Offset +1 I.E. Original: 2109, New 2110 \\ * Sighting HC: +1 I.E. Original: -5, New -4 \\ **Note: After changing the sighting, its advisable to have the operator to verify the new sighting.** ++++ ==== Micrometers ==== **Q:** How do I find the micrometer offsets if I don't know where the HG emission lines are??\\ **A:** {{:docs:finding_micrometer.pdf | Finding Micrometer Offsets from Scratch}} **Q:** What should a grating scan look like when plotted?\\ **A:** {{ :docs:grating_scans.pdf | Troubleshooting Grating Scans}} ==== Old Electronics ==== **Q:** What are the differences between new vs old temperature circuit on the clock board?\\ **A:** Note the resistors on the top left of the boards below (New Vs Old). New temperature circuits, some resistors has been replaced with a jumper wire.\\ {{:pictures:clock_board_old.vs.new.jpg?600|}}\\ **Q:** What is the differences between new vs old temperature circuit on the SPS board?\\ **A:** Old circuit . Power Supply - R601,604 and 605 are 11M and R602,606 and 607 are 1.6M\\ New Sec. Power Supply - R601,604 and 605 are 825K and R602,606 and 607 are 3M\\ **Q:** What pot controls what on the SPS board?\\ **A:** {{:pictures:sps_pots.png?400|}} **Q:** What are the jumper settings for board ____?\\ **A:** ^Part#^J6^J7^J8^J9^J10^J11^J12^J13^J14^J15^J16^ |BA-E50/A|1-2|NC|2-3|2-3|2-3|1-2|1-2|1-2|1-2|2-3|N2| |BA-E50/B|2-3|2-3|1-2|1-2|1-2|1-2|1-2|1-2|1-2|2-3|N4| |BA-E50/D|2-3|2-3|1-2|1-2|1-2|1-2|2-3|2-3|2-3|2-3|N3| |BA-E50/E|1-2|2-3|1-2|1-2|1-2|1-2|2-3|2-3|2-3|2-3|N3| **Q:** What control goes to what connector?\\ **A:** ^Part#^J1^J2^J3^J4^J5^Applies^ |BA-E50/A|NC|Micrometer|Shutter|SPS|NC|MkII & MkIV| |BA-E50/B|Iris|FW#1|FW#2|NC|NC|MkII, MkIII & MkIV| |BA-E50/D|Zenith|Azimuth|FW#3|Control|NC|MkIV| |Ba-E50/E|Zenith|Azimuth|Micrometer#2|Control|NC|MkIII| \\ ===== Schedules ===== **Q:** How do you disable the az check at the start of a the schedule?\\ **A:** Inside the skc.rtn, in line 11022 (about 18 lines from the top), add the instrument number you would like the program to ignore. Note: You may need to add it into the master program directory or disable the instrument from getting its program updated daily. ===== Software ===== **Q:** How do I launch a GUI via remote ssh?\\ **A:** Review https://askubuntu.com/questions/47642/how-to-start-a-gui-software-on-a-remote-linux-pc-via-ssh\\ **Q:** How do you remove ^M in gvim/vim\\ **A:** Type: :%s/^M/ /g\\ (note to type in ^M ctrl+v ctrl+m)\\ ===== DosBox Key Mapper ===== https://www.dosbox.com/wiki/Mapper\\ For keyboard issues where up/down/left/right is not working, try setting setting the following (it may have been set to true) [sdl] usescancodes=false
