Troubleshooting

This section contains troubleshooting tips and answers to questions that SCXI users commonly ask NI
technical support staff.
Tips
Before you contact NI, try the following troubleshooting tips:
• 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.
