On 10/21/2010, jtilley published a spreadsheet named PV750_IO_Test.xlsx. Is this applicable to the PV380, PV450 and PV485? Thanks, David

One of the test engineers told me that the PV750 resistive inputs were done quite a bit differently than the newer displays. He said, for the newer displays counts can be calculated with the formula (using a 400 ohm resistor):

counts = (Input Resistance (ohms) / (Input Resistance + 400)) * 1023

To calculate voltage rather than counts, replace the 1023 with 5V.
