NI Digital Waveform Generator/Analyzer Getting Started Guide
I Received a Thermal or Power Shutdown Error
I received the
kErrorDeviceShutDownDueToHighTemp
or the
NIHSDIO_ERROR_DEVICE_POWER_LIMIT_EXCEEDED
error, and my device shut down.
What should I do next?
To re-enable your device after a hardware shutdown, you must perform a hard reset, in which
the device integrated circuits (ICs) are reloaded. To re-enable your device after thermal
shutdown, complete the following steps:
1.
Power off the computer or chassis that contains the device.
2.
Review the procedure in step
5. Installing the Hardware
and make any necessary
adjustments to ensure that your device is effectively cooled.
3.
Call the niHSDIO Reset Device VI or the
niHSDIO_ResetDevice
function or perform a
device reset in MAX. For more information about performing a device reset in MAX, refer
to step
6. Configuring and Testing in MAX
. The thermal shutdown error continues to be
reported until the device has been successfully reset.
Note
The thermal shutdown error is reported until the device has cooled to an
acceptable operating temperature and has been successfully reset.
Note
Due to power and cooling constraints, not all features of the NI 6555/6556
may be active at the same time. Refer to the
NI 6555/6556 Specifications
for power
limits and to the
NI 6555/6556
book in the
NI Digital Waveform Generator/Analyzer
Help
for more information about the power monitoring properties provided by
NI-HSDIO.
Performance Issues Using MXI Connection
When using a MXI connection to control the PXI chassis, the MXI Optimization Application
must be run prior to using the NI device. By default, this application runs automatically when
Windows starts. Use of a MXI connection without running this application may result in a time
exceeded or internal software error, or an initialization, timeout, or performance issue when
using the NI device.
If you are experiencing errors and are uncertain whether the MXI Optimization Application ran,
navigate to
Start»All Programs»National Instruments MXI
, and select
MXI Optimization
to launch the application.
If the application is not installed, refer to the software CD included with the MXI kit to install
the software. After installation, you may be required to reboot the computer before using the
MXI Optimization Application.
If you continue to have initialization or performance issues, refer to the MXI documentation at
Start»All Programs»National Instruments MXI
, or visit NI Technical Support at
