MED box output to Pulsepal Trigger
#1
Hi everyone,

I have a Pulsepal trigger channel hooked up to a MED behavior box output channel at 5 volts, and I found that the Pulsepal trigger responds only in the pulse-gated mode, but not the normal mode. Would anybody have any ideas to what kind of signal can cause this outcome?

Thank you!

Hi Ben,

Is the 5V output logic-inverted by any chance?
I'd connect it to an oscilloscope to make sure the signal coming out of the MED box is what you expect.

Hey Ben,

I know this post is old but hopefully you may see this! How do you have your pulsepal hooked up the the med boxes? I've been trying to trouble shoot this and still not sure how to use my pulsa pal to trigger after a certain behavior and/or cue. Thanks!
