Connect Card Readers
The Controller provides onboard access control. This enables you to connect two Wiegand devices to control
two doors (entry or exit only), or - if the Controller is configured for multiplex mode - enables you to connect four
Wiegand devices to control two doors giving the flexibility of entry and exit readers, without the need for
additional hardware.
Important:
 Card readers must be connected to the Controller port using a shielded cable.
 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.
 Always refer to the card reader manufacturer for detailed installation guidelines.
All Protege Readers are shipped with single LED mode set as default.
