+===== General Information for focal-plane gas handling system =====
+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:s800fp-win7.nscl.msu.edu'' 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 Labview software communicates with a MKS gas handling system through a Moax Nport 5110 terminal server attached to the bottom of the focal-plane chamber. This terminal server has a hostname s800ghts.nscl.msu.edu, which currently has an static IP address assigned to it (10.65.40.135). When running Labview, go to the Initialization tab and make sure that the terminal server address (IP) and port number (2001) is correct.
+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

-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.

+===== LabView Control Program for focal plane detectors =====
+To start the gas handling system control application, click on the LabView icon **FPGHS_TCPIP_Corrected_V01** on the [[Software|S800FP-PC]] desktop.
-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
+  * The LabView program controls the gas handling system through a Moax terminal server. You have to verify that the address is correct.
+      * Go to Initialization tab
+      * Confirm that the IP address is 10.65.40.135 (or s800ghts) and the port number is 2001
-===== LabView Control Program =====
-To start the gas handling system control application, click on the LabView icon **FPGHS_TCPIP_Corrected_V01** on the [[Software|S800FP-PC]] desktop.
   * A log file should be specified before operating the gas handling system
       * A window automatically pops up asking for the name of the log file when the program starts
-      * Use the number of the current experiment (or "test") as the name of the log file and save in file /intranet/files/departments/operations/s800/TO_BE_SPECIFIED
+      * Use the number of the current experiment (or the date) as the name of the log file and save in the default directory **/projects/s800/Gas logs**
       * The On indicator next to Is VI running? will flash until a log file is specified and the program initiates communications with the hardware
