Very productive day. For safety reasons we are creating two command displays. One display is a "Command Enable" display, which will enable the buttons on the "Command" display. This will ensure that one does not inadvertantly execute a command. It requires two separate operators to make a command happen. One to enable the command the other to actually execute the command. The following are some screen shots of the displays and their LabVIEW logic.
Command Enable:
Note: The LOX/Fuel Main A/B valves are computer controlled. However, we will still operator enable the command before the computer is allowed automate this function.
LabVIEW logic:
Command Display:
Note: The Command display does not include the LOX/Fuel Main A/B. The opening/closing of those valves are handled by the computer.
LabVIEW logic:

We spent time working the issue of sending data over the network. Jason and Zoheb were able to receive data but we had issues with respect to bundling multiple data items together and unbundling them on the receiving machines. This is necessary so that we can timetag the data and bundle many of our data items together to optimize the sending of the data to the various nodes. 4/24 Update: We were able to figure out how to unbundle the data in LabVIEW, it required us to define the data types for each slot in the bundle. Once we did that we were able to pull out the data properly.
We didn't have the cables yet from National Instruments to be able to hook up real sensors. (4/25 Update: the cables arrived). We did use a small analog data ack serial board to read in some data and send that single value over the network.
Close to the end of the meeting we spent time with Rob of the Motor team talking details about the sensors to better understand what kind of sensors we need to purchase.

We welcome Zoheb to the team , he is finishing off FIRST and will be jumping into LabVIEW like the rest of us.
Rob (from the Motor team) came by and showed us the plumbing brassboard that we will be using to test out our commanding software. His team did a real nice job and I think we're going to have fun playing with that!
Jesus completed the initial plumbing displays and at the very end started work on the "Public" display (which we'll use to show on the big screen during the event). Dylan and Zoheb went through the networking examples and we continued to have problems with permissions (Jason and Sudeep remember this from last time). We finally figured out what was going on, we weren't completely shutting down the server.
Next meeting we will be putting together the network VI to be used by the display teams. We're also looking forward to using the donated hardware (from National Instruments) to start reading real data.
