"ievo® desktop readers allow you to conveniently manage the registration of new user fingerprints. Connect the readers directly to the PC through a USB port, and dump the information of the new users to all the readers of the installation. You can use the ""UDR"" desktop reader for installations where Ultimate™ outdoor readers are present, or where both Ultimate™ and Micro™ models are used. On the other hand, the reference ""MDR"" will be used in installations where there are only Micro™ readers."
