CCDS, TIFKAM, 4K, R4K and OSMOS (which uses the 4K or R4K) Data Taking Startup Procedure
Updated 2011 November 22 (Barr/MDM)
Important Change - Read This First!
In August 2005, we removed the WC computer from the OSU data-taking
system, and brought MDM up to OSU's current standard Linux system. This
involves only one old DOS computer (the IC), which should eliminate
most of the startup synchronization problems of the past. It does,
however, require new startup procedures, so read the following carefully.
The startup procedures are identical for the 1.3m and 2.4m telescopes.
At the 2.4m, the Linux workstation is named "hiltner", while at the
1.3m it is "mcgraw". We will generically refer to either as the
"Linux Workstation" below.
Before starting up the data taking software for R4k (2011), 4K, TIFKAM, CCDS and (2010) OSMOS, be
certain that the SCSI disk enclosure is connected to both the IC
and the Linux workstation and the disk enclosure is powered on. In
general, the SCSI disk enclosure should always be connected and
- Make sure the SCSI disk enclosure is connected to both the Linux
Workstation and the IC and powered on.
- Make sure that the instrument is powered on and connected to the
IC via the fiber optic cables.
- Power up the IC, and allow it to boot to the instrument selection
prompt (CCDS, TIFKAM, 4K, R4K or OSMOS (only used at the 2.4m). Do NOT select your instrument until the linux workstation is up.
- After the IC boots, reboot the Linux workstation.
Starting the software
The IC will prompt you for the instrument you want to use. At the prompt
"Select TIFKAM, CCDS, 4K R4K or OSMOS (T/C/4/O/R):" on the VGA screen, go to the
IC keyboard in the computer room and press T for Tifkam, C for CCDS, 4 for 4K or O for OSMOS R for R4K. OSMOS
is only used at the 2.4m with the 4K & R4K. Both 4K and R4K can be used in direct mode at
the 1.3m and 2.4m.
At this point the software will try to initialize all the instrument
components. The monochrome screen of the IC has a line of
status "lights" to indicate the status of each piece of the acquisition
system. Make sure it can see the HE (Head Electronics), Sequencer, and IE
(Instrument Electronics) systems. If there are problems with the
optical fiber connections between the IC and the Head Electronics, the
sequencer start will fail, and the IC monitor screen will show
-SEQUENCER and -HE flags. Correct this before
proceeding (check lights on fibers, look for dirt or lint, proper seating
of the connectors, etc.).
On the Linux workstation, login as "obs24m" at the 1.3m "obs13m", and once the IC is up and
running (above), start the following programs in order from the main
desktop (left-hand mouse button click on the desktop), "Telescope
Initialize both, and wait until both are ready before proceeding.
- On the 2.4m, start the xtcs program or at the 1.3m (
bring up an
xterm window on mcgraw and see if the telescope server is running by
typing telescope status in the xterm window) if the server is running
on hill then start "MDM 1.3m TCS". If the server on hill is not
running Refer to: 5.3 Starting the New TCS
- xmis program
Then start the OSU data-taking system programs using the main
desktop "Data Acquisition" menu, in this order.
Wait for each
program to do a full start before starting the next in the sequence!
In the Prospero window, type "STARTUP" and verify that the instrument
is connected and operating.
- ISIS Server - watch for the IC and IE to acknowledge pings.
- MDMTCS Agent - type "tcinit" then "tcstatus" and verify
that it is communicating with the xtcs and xmis, and reporting
- Caliban - watch for disk synchronization with the IC.
- OSMOS IE Agent: This is used only for OSMOS at the 2.4m and will only be in the 2.4m "Data Aquistion" menu.
