Writing to embroidery card

I am new to Drawings and trying to figure out how to get a design from Drawings X3 to my PE Design Card reader/writer. Starting to think that it is probably to do with the reader/writer as it is a Brother product.

What card reader/writer is one using for Brother .pes files that works within Drawings X3?

Appreciate any help one might be able to forward along.
