Is anyone familiar with the special file needed in order to use NAD27 on a TSC3 running TDS software?

We recently upgraded to TSC3 data collectors and now we get a "projection error" when we select NAD27 datum. I recall that there was a particular file that you needed to have pre-loaded before selecting NAD27. I'd appreciate any suggestions.

Thanks
