I'm trying to perform a digital input acquisition using the cfp 2020-di-330 , but i don't understand how to make the physical connections.
In the diagrams i see two inputs INa and INb, but i don't know which one i have to use since i'll be working with TTL signals.
I have worked with DAQ's , but this is a little differnt, i think i don't need the external supply for doing this.....thanx in advance!!!
Solved! Go to Solution.
TTL signal is applied between INa and INb, reefer to the manual, specifically page 9.
