Tips
Before you contact NI, try the following troubleshooting tips:
•
If you have problems installing your software, go to
ni.com/support/daqmx
. For
hardware troubleshooting, go to
ni.com/support
, enter your device name, or go to
ni.com/kb
.
•

and enter the info code
rdsenn
to start the Return Merchandise
Authorization (RMA) process.
•
Make sure the SCXI chassis is powered on. If you are using a PXI/SCXI combination
chassis, make sure the PXI chassis is powered on.
•
Make sure you have installed the latest version of the NI-DAQ driver software that supports
the devices in your system.
•
If MAX cannot establish communication with the chassis, try one or all of the following:
–
Connect the DAQ device to a different module in the chassis.
–
Try a different cable assembly.
–
Try a different chassis.
–
Try a different DAQ device.
•
Make sure that each SCXI chassis connected to a single DAQ device has a unique address.
•
Make sure that the cable is securely connected to the chassis.
•
Check for bent pins on the module, chassis backplane, and the device connector.
•
If you have multiple SCXI modules, remove all the modules and test each module
individually.
•
If you are getting erroneous readings from the signal source, disconnect the signal source
and short-circuit the input channel to ground. You should get a 0 V reading. Alternatively,
connect a battery or other known signal source to the input channel.
•
Run an example program to see if you still get erroneous results.
