I/O Assistant is easy, but this is not what you want to use in this
case. What you want to do in Labview will be somewhat similar to what
you do in VEE. Instead of using I/O Assistant, use the basic GPIB
functions. Create your controls on the front panel. You can wire
these controls as inputs to the GPIB functions. Example: create a
Numeric control called voltage. On the block diagram, create a string
with the GPIB command except leave out the voltage setting. Use the
Number To String function to convert the control value into a string.
Concat the GPIB command with the voltage control string. Use this as
input to the GPIB write function. If you are familiar with VISA, you
do not have to look up the GPIB command string. You can use the VISA
instrument drivers and wire the front panel voltage control directly
to the VISA function for setting up the instrument. I am sure there
are some examples for the 4142 on the NI website. Good Luck.
