How to hook up the temperature monitoring system


1) Hook up the PC. Keyboard, mouse, monitor, etc. The SCXI-1000 module plugs into the bottom 
card.

2) Hook up the DB50 cable.On the Beam Right side, just below the N2 Supply/Return 
attachments, there is a DB50 plug marked "TEMP." The end of the DB50 with the wires hanging 
from it goes there. The end with a SCXI-1303 block gets plugged into the leftmost SCXI-1102 
module. The power should be off when you plug it in.

3) Hook up the Panametrics Hygrometer. Run the RS232 cable that has one end a nice plug, the 
other end with only three wires soldered to the plug. The nice end plugs in the back of the 
hygrometer, the 3-wire end into the next-to-lowest card in the PC. The hygrometer *must* be off 
when you plug this cable in, but the PC can be on.

The hygrometer digital display should be alternating between the humidity/temp and "Printing." If 
it isn't, read the hygrometer manual (page 3-60) for how to activate the RS232 output.

4) Open LabVIEW. Start -> Shortcut to Common, then find the "_DAQ VIs" icon and open it. Find 
the "2004-06 System Monitoring VI" and open it. Open "_Monitor 04 - Temp, Grad & Humid 
x32.vi". The VI is configured for a 1152 by 864 screen.

When you run the VI, the delay should be on 1 second for a little over three minutes, then 
changed to how often you want to take data. There are size-100 arrays that must empty-then-fill, 
and the fastest way to do that is take data once per second for 200 seconds. You will have to 
right-click on each graph and choose "Clear Graph" in order to get rid of the ugliness.

The first time you hook up the system, go ahead and run the program before the next step.

5) Hook up the 5 V power supply. Just above the DB50 plug is a red & black pair of wires 
soldered to an 80'  gray cable - run this to the Topward 6306D power supply. Use the two center 
pins: black to black, red to red.

Note: Immediately look at the temperatures. If you get the voltage reversed they won't give any 
reading (either 0 or 50 degrees), but the sensors themselves will get very hot. It won't damage 
anything for 10 seconds or so, but don't have it wrong for longer than that.
