-The gas handling systems for both Focal Plane gas-filled detectors – the [[Detectors#Ionization Chamber|Ionization Chamber]] and the [[Detectors#Cathode Readout Drift Chambers (CRDC)|CRDCs]] – are remotely controlled via a single LabView application running on the computer [[Software|S800FP-PC]] in the S3 vault. This computer can be accessed remotely from the desktop of computer [[Software#u6pc5 (data U6)|u6pc5]], by clicking in the icon **S800 Vault PC**, or by typing ''rdesktop -d NSCL_USER -u s800 -g 1600x1000 35.9.56.104'' from a Linux terminal. Once the virtual session in S800FP-PC is open, the gas handling system can be opened by clicking in the corresponding icon on the desktop **FPGHS_TCPIP-II**. This icon opens the local directory 'C:/Users/s800/Desktop/FPGHS_TCPIP-II'. Once there, run the Labview executable **FPGHS_TCPIP-II.exe**

 Note that since the same roughing pump drives the gas handling systems for both gas-filled detectors, extra precautions must be taken to protect one detector from the pressure of the other detector. The fact that the same pump drives both systems is not indicated on the graphics for the LabView control application

-In order to track the status of the gas bottles for the [[Detectors#Ionization Chamber|ionization chamber]], the  [[Detectors#Cathode Readout Drift Chambers (CRDC)|CRDCs]], and the [[Detectors#[Tracking Parallel Plate Avalanche Counters (TPPAC)]|TPPAC]], it is possible to monitor their remaining pressures from Barney. Just open the **A1900** page, then **Tools**, and then **Gas Status**. The following window will be displayed:
