DMX/RDM Shield Arduino Leonardo

Hi,

We are working on a DMX/RDM shield that works with Arduino Leonardo (look here http://www.voltvision.com/products_page/led-controllers/dmx_rdm_arduino_shield/) and basically any microcontroller platform. The thing is that I want the Arduino Leonardo to look like an Enttec USB PRO that can do RDM communication (Master and Responder). Can you help me with that? Does anyone has an idea? It’s possible? Thank you!
