adav,
Connect the output of your charge coverter to the analog input pins of
your tbx 68 in a differential configuration (pin 68 is AI0 and pin 43
is AI8). If your charge converter is not grounded (is floating)
make sure you use bias resistors to give your signal a reference to
ground.
Next, you will need to setup your measurement in MAX. Setup a
voltage task, make sure your input range for your task matches the
output range of the charge converter. You will need to create a
scale to convert the voltage measurements from your charge converter to
the proper acceleration values.
I hope this helps get you started. Please reply with more specific questions as needed.
