Hi,
MAX is reading the former configuration of your sys.ini file for the PXI chassis. So we need to delete that and create a new one.
The best way to solve your problem would be to right-click on PXI System under Devices and Interfaces in MAX. Choose "Delete All Identifications". Your PXI system should then say "unidentified" by it. Right-click again and choose "Identify As", then choose your controller. All your modules and an unidentified chassis should show up. Then right-click on the unidentified chassis and choose the chassis you have. Once it's been identified, press F5 to refresh MAX and then all your devices under Traditional NI-DAQ should have the correct slot number by them.
Let me know if that doesn't work!
