NI 9221 Triggering

[Teekayy]

Hi everyone,

I just had a quick question regarding the NI 9221. I have a cDAQ 9174 and a NI 9221 how would I set a trigger for it? I saw multiple other posts but I still am unsure if this is possible. Thank you. 

More info: I also have a NI 9472 on the chassis that cycles 5V from a power supply that alternates a spdt's TTL logic.

Unfortunately, you would need an additional digital input module. See Setting Up a Digital Trigger in a CompactDAQ Chassis
