OSIRIS Startup Procedure

This document describes the basic set-up for OSIRIS which needs to be done once at the beginning of each observing run. This is NOT a complete guide to the full OSIRIS set-up. The basic OSIRIS "system" should be left intact from observing run to observing run. The reference for a complete setup for OSIRIS can be found here. This Block Diagram shows the complete setup of the OSIRIS system.

The basic OSIRIS system consists of 3 PCs and the sun data taking computer (ctioa1 or ctioa2) as well as the instrument itself. The instrument control software is called ICIMACS: Instrument Control and Image Acquisition System.

One PC is located on the instrument: the "IE". The IE boots on power-up and starts its program automatically (ieosiris.exe). The IE handles low level motor control. The other two PCs are located in the computer room and are connected to each other and the sun machine. The IC is the instrument computer. It handles the basic instrument control and data taking (including the detector readout). The WC is the "workstation" computer. It acts as the communications hub of the OSIRIS system. The WC mediates the communication between the PCs and the sun computer, as well as the TCS. The WC should always be powered on since it has a connection to the sun SBUS on ctioa1 or ctioa2. The monitors and keyboards for the IC and WC are located in the console room. The IC computer and all monitors can be powered off when OSIRIS is not in use. The user interface is on the sun machine and is provided by the computer program "Prospero."

1.) Go up to the telescope. There are two electronics boxes on the instrument. These are the HE (Head Electronics, which run the detector) and IE (Instrument Electronics, which do motor control).

  • Make sure the flat "phone" chord connecting the HE and IE is plugged in. The chord must be plugged into COM1 on the IE; any port on the HE is ok (do not use the port labeled 1 until further notice, USE Port 0).
  • Plug in each of the electronics boxes to a UPS power source.
  • Turn on the power to each box.
  • Connect the optical fibers to the HE.
  • Please check the fiber signal transmission strength at each setup.
  • 2.) Go down to the computer room. The two instrument control PCs are located near ctioa1 or ctioa2.
  • Connect the serial line from the WC (COM1 or COM2) to port B on ctioa1 or ctioa2.
  • Connect the serial line from the WC (COM4) to the TCS (Heurikon).
  • Power up the IC. The WC should be on already. The WC should not be turned off under normal circumstances since it is connected to the sun SBUS.
  • Connect the fibers at the IC. The fiber with light should go to the "dark" connector on the IC.
  • 3.) Go out to the console room.
  • Power on all the PC monitors. The IC has both VGA and monochrome monitors. Initially, the IC will send stdout to the VGA. Type "mono" on the IC keyboard if you want stdout to go to the mono monitor. The WC has only a mono monitor.
  • Start the IC and WC programs on the PCs by typing "IC" and "WC" at the respective DOS prompts.
  • From the IC, type "UARTINIT" to flush the communications buffers and look for a response ("pong received from IE") from the IE. If the IE is not responding, you may have to go to the instrument and reboot the IE (cycle the power on the IE box). On the IC monochrome monitor, you should see a +SEQUENCER flag which indicates the sequencer is up and running. If you see -SEQUENCER, type SEQINIT.
  • You may have to start the "WC" program several times before it comes up successfully.
  • Verify that Ariel, the daemon which handles PC-sun communication, is running on the WC.
  • Check to see if the WC is talking to the TCS. If not, try "TCINIT" from the WC keyboard.
  • Make sure the TCS Router is not being used with OSIRIS. See the troubleshooting page for more info.
  • 4.) Go to the Sun console (ctioa1 or ctioa2) to start the instrument control interface "Prospero."
  • Login as "osiris."
  • Follow the instructions displayed on the screen for "beginning of run" or "new observer."
  • After the openwindows window manager starts, type "startup" in the Prospero command window.
  • The basic instrument status, i.e. motor and data taking configuration, should be displayed in the window above the Prospero command window. You should see an "UP" flag next to all the computers and daemons listed across the top of the display.
  • Refer to the OSIRIS user manual for basic data taking information and instrument control.
  • 5.) If it's not working...
  • If Prospero reports one or more of the links to the instrument computers as down, first check that the connections have all been properly made and/or that they are clean and solid. Once the connections are verified, try restarting (rebooting)  the computer in question (don't forget the IE computer is on the instrument in the IE box).
  • Refer to the Prospero manual (available in the console, or on-line) for Prospero questions.
  • As of this writing, the power on the IE typically needs to be cycled one or more times after the rest of the system is connected. This may be related to a faulty communication port on the HE. Normally, the flat cable between the HE and IE can be located in any of the three ports on the HE. Port 1 on the HE is currently considered unreliable,USE Port 0.
