eDCM 380 Encrypted Two-Door PoE Controller Supporting sPass Readers

The eDCM 380 (Door Control Module) is a low cost, two-door PoE controller designed to interface to CEM sPass DESFire smart card readers.

The eDCM 380 features Power over Ethernet Plus (PoE+) connectivity. Working in conjuction with a PoE+ Midspan power injector between the network and the door, the eDCM 380 can power door furniture and two maglocks via a single CAT 5e/6 network cable. PoE+ also has the benefit of eliminating the need for an external local mains power supply at the door. Using just a single Cat 5e/6 cable to power the door(s), the eDCM 380 unit can offer significant cost savings.

eDCM 380 supports CEM sPass DESFire smart card readers via encrypted RS485 interface. By utilizing encrypted RS485 serial communications between the DCM 380 controller and the sPass reader, the threat of Wiegand controller signal cloning is effectively eliminated.

The eDCM 380 supports two door configurations. It can either be configured for one sPass reader on each separate door, with optional Exit push buttons, or can be configured to support two sPass readers (an Entry/Exit configuration) for bi-directional control on a single door.
