eDCM 350 OSDP IP encrypted door controller

The CEM eDCM 350 (Door Control Module) is a low cost, intelligent two-door IP controller that is designed to interface to Open Supervised Device Protocol (OSDP) compliant third party smart card readers.

By utilizing RS485 serial communications with strong AES 128 encryption between the eDCM 350 controller and the OSDP compliant reader, the threat of Wiegand controller signal cloning is eliminated.

Using a powerful 32bit processor, the eDCM 350 gives full off-line verification and decision making at the point of entry, even when host communication is not available.

The eDCM 350 supports two door configurations. It can either be configured for two OSDP compliant readers on two separate doors, with optional Exit push buttons, or can be configured to support two OSDP compliant readers (an Entry/Exit configuration) for bi-directional control on a single door.
