Sorry, my bad - port A1 is NOT working - I forgot they started at zero.

Thanks for your reply. The problem I'm facing is that if I connect a switch as shown on page 3-3 of the manual to port A:2, I cannot see it changing in DAQami when I toggle the switch, even if I only have that port enabled. Port A:1 works fine.

I recently purchased a USB-1024LS from DigiKey, and some of the digital inputs on port A do not appear to be working in DAQami. I can see A:0 and A:4 changing the graph when connected to GND, but not any of the other connections on that port – they just appear to read high constantly. Am I doing something wrong, or have I received a faulty unit?
