II. Converting Raw Data of analog input and
analog output to Engineering Unit
In InTouch, you can convert raw data of AI and AO to engineering unit in

5V and the data range of AI raw data is 0 to 4095 for PCI9112. You can
set the range of engineering unit and raw data as the following figure:
Since the data conversion will be performed by InTouch, it’s very convenient
for users using engineering unit to perform AI/AO in InTouch.
