Hello Salih. Thank you for contacting National Instruments. The first thing that I would like to point out is that MAX 3.0.1 is not compatible with the SCXI 2400 and SCXI 1200. This probably means that you have the wrong version of NI-DAQ as well. Go to Add/Remove Programs in the Control Panel and remove MAX and NI-DAQ. Next, go to ni.com/support and click on Drivers and Updates. Product Line: Multifunction DAQ, Software: NI-DAQ, Software Version: 6.9.3, Operating System: Windows 98. This version of NI-DAQ will install the correct version of MAX.
After you have the correct version of MAX and NI-DAQ, open up MAX. Right click on Devices and Interfaces and add the SCXI chassis. To add the modules, right click on the Module and select "insert". Make sure that SCXI 2400 is in slot 1. After everything is setup in MAX, right click on the chassis and select test. This will tell you if you have configured everything properly.
I ran into a problem with this setup. If I used the SCXI 1200, I couldn't get everything to work properly. However, if I just took it out and used the SCXI 2400, SCXI 1102, and SCXI 1303 everything worked how it was supposed to. I hope this helps! Have a great day!
