Thanks for the reply Patrick.
this is the section of the document that is confusing me:
"Converting the voltage to pressure (kPa) is not specific to this example, it is handled by the Phidget libraries, with functions you have access to when you begin developing!"
given this sentence it is my belief that the PressureSensor API should work with this device. Is that incorrect? (I am not even able to get the Pressure.py example to work).
The error I get after uncommenting and using the same channel and hub port that works with the VoltageRatio.py example is timeout (waiting to attach).
