StrainBook/616 User’s Manual 968594 Troubleshooting 11-3
1. StrainBook does not communicate with the PC.
Possible Causes Details and Possible Solutions
There is a
problem with
StrainBook’s
power.
If the StrainBook system and the host PC fail to communicate with each other, verify that:
(1) the StrainBook is powered on, and that (2) the power supply is not overloaded.
Check the power requirements of each component to ensure that the use of the system’s existing AC
adapters is sufficient. If not, use additional AC adapters, for example, one for each component; or at
least to create smaller power daisy-chains that do not exceed the adapter’s limits.
Faulty Ethernet
cable or
connection
The Ethernet cable may be loose, damaged, or not connected. Check the Ethernet line and its
connections at the StrainBook and at the PC Ethernet jack, or Ethernet Network hub, as applicable.
For related information refer to table 14, Ethernet Problems.
The selected
protocol is not
compatible.
In regard to Ethernet Connections – Run the Daq Configuration applet from the Windows Control
Panel. Make sure the device is configured to the appropriate Ethernet port with the appropriate
protocol. Run the device test and if it fails try other protocols for the device.
Note: Before re-running the test, be sure to click on the
button to apply the settings.
For related information concerning Ethernet connections refer to table 14, Ethernet Problems.
Another
application is
communicating
with
StrainBook.
StrainBooks are limited to communicating via one software application at a time. Thus, if an
application such as LabVIEW, DASYLab or a custom API currently has communication established
with the StrainBook, WaveView will not be able to communicate with the device. In the case of
DASYLab, simply having a worksheet open that references a particular unit, will not allow any other
application [such as WaveView] to open communications with that unit.
A WBK30 has
been removed.
If a WBK30 memory option has been removed and the three associated bypass jumpers have not been
installed inside the StrainBook (on header J101), communications to the PC will not occur.
StrainBook users will need to contact the factory in regard to WBK30 issues.
2. “Simulated Device” is the only device.
Possible Causes Details and Possible Solutions
There is no
device handle
for the
StrainBook in
the Daq
Configuration
applet.
When the simulated device is the only device that can be selected in WaveView, the problem is most
likely that there is no device handle for the StrainBook. Device handles are created in the Daq
Configuration
control panel applet by the user. The applet can be accessed from the Windows desktop
by navigating from the Start menu as follows:
Start ⇒ Settings ⇒ Control Panel ⇒ Daq Configuration
Any StrainBook devices that are currently configured in this utility will appear in the list of available
devices in WaveView. Refer to Appendix A, Using the Daq Configuration Applet for details on how to
create a device handle.
