| The SRS 200 Residual Gas Analyzers is currently connected to the first serial port on the c0rga computer. The c0rga computer is a very old dual boot windows XP and ubuntu machine. When rebooting, it defaults to the ubuntu side. When working at the machine physically, logging in the Gnome Failsafe terminal is recommended, as the normal gnome terminal tends to freeze. It is recommended to simply remotely log in from one of the control machines rather than going out to the machine. |

More explicit instructions - just type the following: cd /cvs/cds/caltech/scripts/RGA/ emacs RGAset.py In emacs, scroll to the middle of the file until you see something like commands = [ .

For example, to change the maximum AMU to 130, change 'MF114', to 'MF130',. Save the file with your changes. (In emacs type ctrl-x then ctrl-s to save. Then to quit, type ctrl-x then ctrl-c).
