If I'm still using the digital input, why would it work now?
You found the right thing. The reason you always see "false" on the digital input is that the GTS output is a very short pulse. You probably won't notice it unless you watch it with an oscilloscope. The FPGA in the cRIO can monitor the signal continuously and increment the counter every time it appears.
