Sure you can mix the types of channels, though the 6230 only has 4diff/8se and not the number you mention. You can do it in MAX or in your code. In MAX, simply select the terminal configuration for each channel. I don't know what progamming language you are using since you do not mention it but if it is LabVIEW, you simply use a separate DAQmx Create Channel function for the diff and se channels.Don't forget to account for the fact that each diff channel requires two actual physical channels. So, if you select ai0 for diff, that also uses ai4.
