Issue Details

I need more slots than what my cDAQ chassis provides. Is there a way for me to expand the chassis so that I can add more modules? 


You can incorporate another cDAQ chassis into your system for more slots. If you are using a cDAQ with an embedded controller (cDAQ-913x series), you can connect a USB or Ethernet cDAQ directly to your cDAQ controller.

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.
