After checking the preceding items, retest the SCXI chassis.
•
If the SCXI-1600 is not detected, complete the following steps:
1.
Press <F5> to refresh MAX.
2.
Verify that the SCXI-1600
Ready
LED is bright green. If the LED is not bright green,
power off the chassis, wait five seconds, and power on the chassis.
If these steps do not successfully configure the SCXI system, contact NI. Refer to the
Technical Support
Information
document for contact information.
Step 14. Take an NI-DAQmx Measurement
This step applies only if you are programming your device using NI-DAQ or NI application software.

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.
