Input range for different channels

Question

Hi,
In one of my experiments, the data I acquire in different channels have different magnitudes (in Volts). Therefore, I am trying to set a different input range to these various channels. Here's a picture (input_range.png) of a part of my VI where I am trying to assign input ranges to the analog input channels.
Channels ai0-7 have the range +/-200mV and channels ai8-15 have +/-500V. I do not have the equipment with me at the moment, so I can't test this. But I am wondering whether this is how you would normally set different input ranges for different channels or whether there's a better way to do this.
Cheers.

Answer 1

Thanks for the quick reply Mike.
I found the following post which showed me how to do it

However, I am having difficulties in actually acheiving this. Firstly, I don't know how to set up the arrays as he's done there. Secondly, I could not get the auto-indexing to work. I've attached a pic of my attempt. When I try to enable auto-indexing on the right-hand side of the for-loop it breaks the wires and I can't even enable auto-indexing on the left hand side.
Will it be possible to attach a VI for this part so I can see what functions you've used.
Cheers.
