Prox–DU and Prox–SU differences
The main difference between the Prox–DU and Prox–SU models is related to the smart card
slot:
• Prox–DU: the smart card slot located in the top cabinet is open. The user can insert
or remove its ID-1 size smart card directly into or from the reader slot

• Prox–SU: the smart card slot located in the top cabinet is closed. The user should
open the casing before inserting its ID-000 size smart card into the dedicated
connector. When the casing is closed the SIM/SAM card cannot be removed.
