4 Troubleshooting
4.1 General Software Issues
Q1 When I try to open a QNET Physics and Dynamics VI, it says there are some missing VIs and they have a
CD
or
Sim
in the name?
The LabVIEW™ Control Design and Simulation Toolkit is not installed.
Q2 When I open a QNET Physics and Dynamics VI a message prompts that a VI with ''ELVIS'' in the name cannot
be found?
The QNET Physics and Dynamics VIs use the ELVISmx drivers. Make sure you install the contents of the NI
ELVIS II CD before attempting to open any of the QNET Physics and Dynamics VIs (available for download at
www.ni.com ).
4.2 General Hardware Issues
Q1 The
+5V
LED on the QNET Physics and Dynamics is not lit.
Make sure both the
System Power
switch, which is located on the back of the NI ELVIS II unit, and the
Prototyping
Board Power
switch, which is situated on the top-right corner of the NI ELVIS II, are ON .
Q2 The Ready LED on the NI ELVIS II does not go on.
(a) Go through the NI ELVIS II setup procedure outlined in the QNET Physics and Dynamics Setup Guide
(b) Once completed, launch the Measurement & Automation Explorer software.
(c) As illustrated in Figure 4.1 , expand the Devices and Interfaces and NI-DAQmx Devices items and select
the NI ELVIS II device.
(d) As shown in Figure 4.1 , click on the
Reset Device
button.
(e) Once successfully reset, click on the
Self-Test
button.
(f) If the test passed, reset the NI ELVIS II (i.e. shut off the
Prototyping Board
switch and
System Power
switch
and turn them back on again). The Ready LED on the NI ELVIS II should now be lit.
