[labnetwork] Fw: Implementing Lock-out/Logins on AJA Phase II J sputter system

[Chito Kendrick]

I like the vent line for deposition tools as it is likely the first 
thing they have to do to get a sample in, but then it might depend on 
how you log their usage.


Also, it is very easy to put a solenoid/relay on a air line or control 
line to cut the pressure.
