Card Reader Connection
Both the Protege DIN Rail Controller and RDM2 provide access control functionality allowing the connection of 2
Wiegand devices to control 2 doors (entry or exit only) or they can be configured in multiplex mode to allow 4
Wiegand devices controlling 2 doors giving the flexibility of entry and exit readers without the need for additional
hardware.
 The card reader must be connected to the Controller port using a shielded cable
 Always refer to the card reader manufacturer for detailed installation guidelines
 The shield connection must only be connected at one end of the cable in the metallic enclosure (frame
grounded)
 Do not connect the shield to a V- connection on the Controller
 Do not join the shield and black wires at the reading device
 Do not connect the shield to any shield used for isolated communication
All Protege Readers are now shipped with single LED mode set as default.
