CRIO-9014 and NI-9403 generate pulse in Labview FPGA

[kaan13]

Hello everyone,

I have 5V TTL NI-9403 DIO module and I want to generate some pulses by using the module. I have very basic program and I connected the module's DIO 01 channel to the oscilloscope's positive prob and module's COM channel to the oscilloscope's negative prob. According to program when it is sent true signal to the DIO module, would I see 5V pulse on the oscilloscope?

When I started the program, I couldn't see any pulse on the oscilloscope.

How can I generate pulses using the digital module with Labview FPGA programming? 

Kind regards,

Kaan

Wrong node! You are setting output enable, which is equivalent to setting tristate.  You need to write to the output with the write node, not the line state method
