Python and U6

I am trying to set all the flexible inputs (FIs) to analog and read voltage.  I am using a U6 since it has the voltage capability.  Need > 3.5 volts.  I found examples for python and the U3, but when I mimic those commands for a U6 I get errors.  This is what I have that works for U3.  What should I do for the U6?

import time
import numpy
import scipy
import u3, time
from datetime import datetime
import time
timestamp =(datetime.now())
d = u3.U3()
print d.configU3()
print d.getCalibrationData()
d.configIO(FIOAnalog= 255 )
print d.configU3()
print d.getCalibrationData()
input0 = (d.getAIN(0))
input1 = (d.getAIN(1))
input2 = (d.getAIN(2))
input3 = (d.getAIN(3))
input4 = (d.getAIN(4))
input5 = (d.getAIN(5))
print timestamp, input0, input1, input2, input3, input4, input5

This Does Not work for U6

import time
import numpy
import scipy
import u6, time
from datetime import datetime
import time
timestamp =(datetime.now())
d = u6.U6()
print d.configU6()
print d.getCalibrationData()
d.writeRegister(50590, 15)
print d.configU6()
print d.getCalibrationData()
input0 = (d.getAIN(0))
input1 = (d.getAIN(1))
input2 = (d.getAIN(2))
input3 = (d.getAIN(3))
input4 = (d.getAIN(4))
input5 = (d.getAIN(5))
print timestamp, input0, input1, input2, input3, input4, input5

It says AIN not valid, if I try FIO(x) it says illegal analog command on digital line

Thanks for your help
