P45 + PC SETUP AND CHECKOUT
Last update 04/05/2005 MF

At the 36" (Setup similar at the other telescopes):

Setup

 1) Put the PC monitor, PC (Photon) and interface box in the control room.
 2) Mount p45 on the telescope.
 3) Mount photometer on guider.
 4) Connect cables as shown in diagram. RS-232 cables are stored in the locker
    in the 82", and the long BNC's are either there or somewhere around the
    82" control room.
 5) Balance to current chart.
 6) Put any requested filters in the control room near the night report.

Checkout

 1) Set filter wheel to position 1.
 2) Turn on filter motor power (big power supply in control room). Make sure
    it's reading at least 2 amps. At the 107", you will need to bring the
    filter motor power supply from pier storage. It should be with the p45
    stuff and Photon.
 3) Turn on PC monitor and PC. It should boot at this time and give you a
    C> prompt.
 4) Turn on Clemens interface box (IFB).
 5) Start QUILT by typing   q9   <ENTER>.
    At the bottom of the SET mode window, the message 'Found interface box,
    but no 1 HZ synchronizing pulse' should appear. If it doesn't find the
    interface box, make sure the cables are tight, exit the program (Hit
    <CNTL><SHIFT><ESC> simultaneously), then restart the program.
 6) Enter filter times of 1s for each of the filters. Use arrow keys to
    move down the screen, then edit the field (overprint).
 7) Set motor type 2.
 8) Go to run mode by hitting <ESC>.
 9) Start an integration with F10.
    Check the filter wheel. Make sure it is working properly and turning
    the right direction (clockwise). If it is going backwards, you probably
    have the p23 cable connected to the IFB.
10) End the run with <CNTL>F10 (simultaneously).
11) Go back to SET mode   <ESC>.
12) Set F3 and F4 filter times to 0.000.
13) Go back to run mode    <ESC>.
14) Start integration   F10.
    Check the filter motor. It should be moving back and forth between 1 and
    2. Stop the integration  <CNTL>F10. Leave the program in RUN mode.
15) Make sure the dark slide is closed (on both channels), then turn on 
    photometer power supply (on back of guider) SLOWLY to the proper voltage
    for the tube you are using. It is written somewhere on most of the tubes.
16) Check the QUILT monitor. In the IDLE mode, you should be able to see the
    count rates for both channels. The vary from approximately 0-30 cps for
    channels 2 and channel 1 depends on the tube. Most of the time, it will
    be greater than 0 cps no matter what tube you've got. Things to check if
    you're getting no signal:
    a) Is it cabled correctly?
    b) Is the IFB still detected by the program? It will tell you when it
       loses it. If it has, the program will need to be restarted after you
       reconnect/tighten/adjust the cables.
    c) Getting power from the power supply? It makes a high-pitched (but
       not loud) whine when you turn the high voltage up past 1000 volts or so.
       (The power switch must be up before the voltage levels are set.) 
    d) make sure all the necessary patch panel cables are connected under
       the main telescope console.
    e) You may have a bad cable.
17) Point the observer to the QUILT manual (online)
    if he/she has not used the program before. The observer needs to bring
    diskettes (3.5" high density) to take their data back on. 

At the end of the run

 1) Make sure the dark slide is closed and all filters removed from the
    filter wheel.
 2) Turn off and unplug the IFB before anything else. Then disconnect the PC,
    etc.
 3) The photometer most likely goes back to the 2nd floor 107" closet. 
    The filters either go to the cabinet in the photometry lab (Room 103) or
    to the 107" or 82" filter storage area they came from. The rest of the
    stuff (except the RS-232 cables) goes back to pier storage.
 4) Any filters go back where they belong (full sets to the photometry lab,
    individual ones to their normal homes--107 coude, etc.).
