• Log in as apar@adaq1
• In a terminal type startcoda
  • 4 xterms will appear as well as the main CODA window (see Figure 1)
  • CODA will automatically load the last configuration used. If you are ok with this then just go to Platform->Connect
• To change the configuration, choose Configurations->Cool
  • Select the desired configuration from the dropdown list (see Figure 2)
  • Production running would be PREX
  • Once you have loaded a configuration, some of the icons (see descriptions below) will change from grey to green

Starting a run

• After starting the GUI and loading a configuration (see above)
• Prestart (third icon from the top left)
  • In the previous steps, warnings about waiting for a roc can be ignored if it does not take too long to respond (~10s). Do watch for Error messages. Those cannot be ignored!

Description of the icons

Numbered from the top left of the GUI window (see any of the Figures):

1. Configure (tools) - this opens a drop-down menu to choose the configuration
2. Download (floppy disk) - this loads the chosen configuration
3. Prestart () - this will prepare to start a run
4. Start (triangle with point to right) - this starts a run
5. End (square) - this ends a run
6. Fast Forward (double-triangle pointing right) (rarely used)
7. Rewind (double-triangle pointing left) (rarely used)
8. Pause (two vertical bars) - pauses a run (rarely used)
