Setting up the Analog Inputs (J9)
The J9 port can be used to bring in eight
multiplexed 12-bit single-ended analog
inputs using the traditional Option 12.
These analog inputs can be used either in
unipolar mode in the 0V to +10V range, or
bipolar mode in the -10V to +10V range.
Each input has a 470Ω input resistor in-
line, and a 0.01 μF resistor to ground
ensuing a 4.7 μsec time constant per input
line.

Note
A SAVE and a reset ($$$) is required to initialize this function
properly after download.
Note
In Unipolar mode, the ADCs can measure up to 12V since the op-
amps are powered with 12VDC.
