Voltage divider for differential input - 01/05/2018 10:42 EDT

Paid on delivery
We have a data acquisition system with a differential input which only accepts signals from 0-3 volts. We have a 0-5 volt signal we need read by this input. I've attached pictures of 2 different voltage dividers, the classic divider labeled "DoesNotWork" and something we stumbled upon labeled "Works". We are not sure why the "Works" one does work. We are looking for someone to explain why it does work, or suggest a better type of PASSIVE voltage divider for this differential input.
