EIA-ISO activation code for the subspindle Mazatrol 640T

Hi,
we have Mazatrol 640T, we also use Feature CAM, but we can not using our subspindle when we post the G-Code from Feature CAM, if there is because we don't have EIA-ISO activation code for the Mazak (if there is some kind of these codes?), or may be there is different in codes generated from feature cam than Mazatrol 640T for the subspindle, or some parameters out of range. I think our problem in EIA-ISO, some body have any idea.
and how to shifting from Mazatrol to EIA, what is the Parameter setting need to be changed.


thanks very much
