  • CompactDAQ Chassis
  • NI-9469
  • CompactDAQ Controller

Issue Details

My current application requires more slot than was is currently available to me on my current cDAQ chassis. Is there a way for me to expand the chassis so that I can add more modules? 


Here are the options available:
  • You can expand your application to include another cDAQ chassis for more slots.
  • If you are using a CompactDAQ system with an embedded controller, such as the cDAQ-913x (which are now legacy), you can connect a USB or Ethernet cDAQ directly to your cDAQ controller and be able to access the slots on the secondary chassis.
  • Depending on the requirement, you can also opt for the 14-slot cDAQ-9179, which is National Instrument's largest slot chassis. 

Additional Information

​If you need the two chassis to be synchronized, use the NI 9469  to route trigger and clock signals between the chassis.
