If the chassis embedded controller and the operating system (OS) installed on the controller is Windows (non-real-time), you can install MATLAB as an application running on the controller. MATLAB can then control the local NI DAQ PXI modules via the NI-DAQmx library. You can remote into the controller using remote desktop tools just like any other Windows computer.
If the controller is running a real-time OS, it is not possible to remote control the NI DAQ PXI from an external computer just using NI-DAQmx, so a remote control option is needed (MXI Express or Thunderbolt as described below) for use with MATLAB.
The supported solution to control NI DAQ PXI(e) modules from an external computer via applications that use the vendor's NI-DAQmx library (such as MATLAB) is to use either:
1. An MXI-Express kit (which consists of a PXI remote control module, MXI Express cable, and MXI host interface card)
2. A PXI Thunderbolt remote control module
These PXI hardware accessories can be purchased from NI.
There is a PXI Remote Control and System Expansion product flyer with more details, linked below:
