| - | The main control interface during an observation is [[http://www.econtrol-software.de/|e-Remote Control]], which communicates with the PC Field System (PCFS) machines at the observatories. All the computers at the observatories have names ending with their two-letter telescope ID: | + | If you are unfamiliar with the computers and software used at the sites and in the control room, please read this before continuing: |
| - | * Hb = Hobart 12m | + | * [[[[operations:documentation:computers_software|Introductory notes on computers and software]] |
| - | * Ke = Katherine | + | |
| - | * Yg = Yarragadee | + | |
| - | There are four computers at each site that run the most important items of hardware or software. They are: | + | |
| - | + | ||
| - | ^Type ^ Function ^ Computer Name ^^^ Access with... ^ | + | |
| - | ^ ^ ^ Hobart ^ Katherine ^ Yarragadee ^ ^ | + | |
| - | |PC Field System | Linux PC that runs Field System software to control the antenna, DBBC and Mark5 | pcfshb | pcfske | pcfsyg | ssh, VNC (display 1) | | + | |
| - | |Mark5 recorder | A Linux PC inside the Mark5 recorder which runs dimino, a program the PCFS communicates with to control data recording | mk5hb | mk5ke | mk5yg | ssh | | + | |
| - | |Timing PC | Windows PC that monitors the H maser, the CNS-II GPS clock, shows the wind speed and direction, and runs HMI: a GUI for controlling and monitoring the antenna | timehb | timeke | timeyg | VNC display 0| | + | |
| - | |DBBC | A Windows PC in the DBBC which runs a server (and optionally a client) program to allow control and monitoring of the DBBC | dbbchb | dbbcke | dbbcyg | VNC display 0| | + | |
| - | + | ||
| - | Each of the above can be accessed either through a terminal via ssh or by starting up a VNC session. It is necessary to bring up the VNC sessions when setting up for an observation or when doing one of the regular ~2 hourly system checks. Given the slow network connection to Yarragadee it is not recommended to keep the VNC sessions up at other times. | + | |
| - | + | ||
| - | VNC or terminal sessions can be started via the Application menu on ops2 in the top left of the desktop. e.g. for Yarragadee: | + | |
| - | Applications -> AuScope Yarragadee -> VNC -> [choose the server] | + | |
| - | {{:operations:ops4applicationsmenu.jpg?500|}} | + | |
| - | + | ||
| - | VNC sessions can also be started up on the command line. e.g: | + | |
| - | <code> | + | |
| - | vncviewer -shared pcfshb:1 | + | |
