Hi all,
I have a Linemaster T-91-SC36 foot pedal that I want to interface with an ELVIS II. I'm using the foot pedal to mark an observation and then I will compare the timing of the observation to the data that's simultaneously being recorded. Because it is the timing that I'm comparing, I want to sample the foot pedal and the other data at the same rate. Can I wire the foot pedal's two outputs to an analog input and sample the voltage along with the other data? How do you usually interface a foot pedal with a daq?
Thanks!

The foot pedal would be sampled using a digital input, if it is a switch (pushed/not pushed). If the pedal is a potentiometer, then you would need to supply a voltage on the input, and read the output using an Analog In.

I'm pretty sure it's a switch (although the data sheet doesn't tell me much). Assuming it is a switch and I sample it with a digital input, how do I sample analog (my other data) and digital simultaneously both at 1375 Hz?
