Hello,
I have a NI 9401 and a cDAQ 9174. I tried to use the counter-count edges example vi to acquire the number of edges of a 5V TTL signal. I wired the TTl signal to DIO1 of NI 9401 and configured "cDAQ3Mod3/ctr0" for the counter. How can I configure the digital trigger source in the arm start trigger? What routing should be made?
Anybody can help me please?
