Rack Door Unit

Rack Door Unit


This daisy-chain expansion board (called RDU) connects directly to the RAMOS Ultra Unit's expansion ports and gives you full  access to the racks, cabinets, aisles and rooms and shows who accessed the equipment and when. On each RDU can be connected one reader and one lock or two latches with RMS-CON-ACS (with restricted functionality). Up to 25 RDUs can be connected in a daisy-chain to each expansion port on a RAMOS Ultra unit.

The maximum number of RDUs that can be connected to a single RAMOS Ultra unit is 100. The maximum cable length for connecting (via LAN cable) between a RDU’s and RDU with a RAMOS Ultra unit is 300 m. To access administration, you will need to use CONTEG Pro Server management software, which provides you user/group management, user access schedules, advanced analytics and notifications, time-stamped video and much more.
