Before you start

Before you start any activity read the News. Read and understand the relating articles Telescope pier collision avoidance and Dome slit synchronization.

The user for the operations is obs.

Make sure that you check if somebody else is using the computer miyo.obsvermes.loc using

who

and if a user is logged in use

talk user

to get in contact. By definition the person who powered on miyo.obsvermes.loc is the primary user.

If the response is even on the shell slow, read the section Network Bandwidth consideration.

Emergency Shutdown

on miyo.obsvermes.loc

/usr/local/bin/instruments_OFF
/usr/local/bin/dome-power-off.sh
/usr/local/bin/fli_OFF

After the dome motor has been stopped (second line) the WLAN connection to the computers and camera on the dome is interrupted.

Power

Current Layout (2009-08-07).

All systems with the exception of

are usually shutdown if no observation is in progress.

In case the IP9258 does not switch the outlet, follow theses instructions.

There are three IP 9258 power switches installed which can be reached on obsvermes.obsvermes.loc with the script setpower.sh. The current layout can be seen on the figure on the right side.

ip9258 networked power switches indiserver

Since 2009-09-26 there is installed on obsvermes.org the infrastructure to actuate the IP9258 power outles of observatory vermes.

There is an indiserver started from the shell script

 /home/lukas/bin/start_ip9258_server

listening on port 7623 which may be connected to via ssh with the command

  ssh -N -f -L localhost:7624:localhost:7623 obsvermes.org

The configuration for the three IP9258 indi drivers started is in /etc/indi/ip9258

to power on the systems on the dome.

Kernel modules

If not loaded at boot time then manually load the FLI kernel module

modprobe fliusb

and check the devices

crw-rw---- 1 root root  180,  240 2008-03-24 12:01 fliusb0
crw-rw---- 1 root root  180,  241 2008-03-24 12:01 fliusb1
crw-rw---- 1 root root  180,  242 2008-03-24 12:01 fliusb2
Time
  • Check if ntp are running on obsvermes.org, miyo.
  • Make sure that all devices have the same time within a second and that it is the correct local time.
Video cameras

Setup the SSH port forwarding. On miyo.obsvermes.loc check if all video devices are available

lrwxrwxrwx 1 root root 6 2010-03-13 15:30 /dev/stvvideo -> video0
lrwxrwxrwx 1 root root 6 2010-03-13 15:30 /dev/wallcam1 -> video1

If not reboot miyo.

And the same on lukalix.obsvermes.loc:

crw-rw---- 1 root video 81, 0 2010-02-27 17:46 /dev/video0

If not reboot lukalix.

The essential streams on miyo.obsvermes.loc are started at boot time. If no stream is present, turn at least one camera on following the procedure Standard ports and streams. After a ssh tunnel to obsvermes.org has been established e.g. use on the local computer

mplayer -framedrop -nocache http://127.0.0.1:3080
mplayer -framedrop -cache 32 http://127.0.0.1:3080

to display the stream of the webcam on the dome. To minimize the delay of the stream press one or two times "]" in the mplayer window.

INDI SBIG STV server

The following script starts the indiserver for the SBIG STV

/usr/local/bin/start-stv

Sometimes the STV looses contact to the host computer. It is necessary then to restart the indiserver. Use a separate indiserver for that reason.

obs@miyo:~>indiserver -p 9624 /usr/local/src/svn-vermes/indi_drv/STV/stv

If you receive something similar

./indiserver: bind: Address already in use stv: EOF

the observatory is already in operation. Try to contact the operator.

Start

  • start lukalix
  • /etc/init.d</rts2 start

Stop

Pause and resume
