To assemble the QNET Rotary Pendulum, please read the following instructions carefully, For full details, see the QNET Rotary
Pendulum User Manual.
Remove the four
thumbscrews
located on the
bottom of the
Pendulum base.
Bring the pendulum assembly upright
and align the screw holes on the bottom
of the pendulum base with four holes
on the surface of the QNET board.
Note: Make sure the exposed side
connecting the cables is facing the
back of the board.
Tighten the four thumb
screws to secure the
arm to the QNET board.
When assembled,
the system should
resemble the QNET
Rotary Pendulum
shown in Step 1 .
Slide the PCI
connector at
the back of
the QNET
board into
the female
connector on
the NI ELVIS II.
Place the handle
on the front of
the QNET board
over the bracket
located on the
front of the NI
ELVIS II.
Connect the NI
ELVIS II power
supply to the
back panel of
the NI ELVIS II.
Use the NI ELVIS II
USB cable to
connect the NI
ELVIS II unit to
your computer.

Ensure that the
+15V, -15V, +5V,
and the External
Power LEDs on
the QNET board
are lit.
Click on the
STOP button
to stop run-
ning the VI.
Click on the
white arrow
to run the VI.
Ensure that the
pendulum is in
the downward
gantry position,
and is perfectly
stationary.
Slowly raise the pendulum
to the upright position.
When the pendulum is close to
vertical, the controller will activate
and attempt to balance the
pendulum. Immediately release
the pendulum when you feel
the controller engage.
Select the device
name to match your
NI ELVIS II device as shown
in the NI Measurement &
Automation Explorer in the
Device control.
The scopes should look similar to those shown here.
Otherwise, consult the troubleshooting section at
the end
of this
guide.
Open the LabVIEW VirtuaI Instrument
(*.vi) found under the Quick Start folder
GPower on the NI ELVIS II using the power switch on the
back of the unit. The READY and ACTIVE LEDs on the
top NI ELVIS II panel should briefly light, and the READY
LED stays on.

At least one of
the+15V, -15V,
or +5 LEDs on
the QNET Rotary
pendulum board
are not lit.
• Ensure that the PCI connector on the QNET board is properly connected to the female
connector on the NI ELVIS II unit.
•Check that the system power switch, located on the back panel of the NI ELVIS II unit,
and the prototyping power switch, situated on the top of the NI ELVIS are ON.
•If one or more of the +15V; -15V; or +5V LEDs is still not lit, then the 15V or +5V fuse(s)
on the Protection Board of the NI ELVIS II has been triggered. Similarly, if the External
Power LED is still not lit after connecting the QNET Rotary Pendulum power, the Var iable
Power Supplies Fuses on the NI ELVIS II Protection Board have been triggered. See the
Protection Board Fuses in the NI ELVIS II User Manual.
The +15 V; -15 V;
and +5 V LEDs
on the QNET
Rotary Pendulum
board, are bright
green but the
External Power
LED is not lit.
• Ensure the supplied QNET power supply is connected to the QNET board.
• If the External Power LED still does not light up, the QNET fuse may need to be replaced.
