Configuring your SCXI system in RT is different because you are configuring a remote system - an entirely separate DAQ configuration than your host PC. In other words, there's one *.daq file (file containing MAX configuration) for your host PC and one *.daq file for your remote system, located on your remote system.
To configure the SCXI chassis on your remote system, you need to differentiate which configuration file you're currently working with. If you simply configure the chassis from your host computer by adding an SCXI chassis in Devices and Interfaces, it will try to add the chassis to the DAQ device located on your host system. Your options to add the chassis may be gray because you do not have a DAQ device on your local system.
To configure your
remote system, go to Tools->Traditional NI-DAQ Configuration->Remote DAQ Configuration and enter the IP address of the remote system. This will allow you to view and configure the DAQ configuration of the remote system. For more detail, check out the following

As a side note, DAQmx is not yet supported in RT.
Please let me know if you have any further questions. Have a great day.
