 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 ''xfreerdp /u:s800 /v:35.9.56.104'' from a Linux terminal. A terminal will pop-up asking for the s800 password. 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**.  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.

 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 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.
