Multiple Wiegand Card Reader Connection
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). The beeper output on the Controller provides
diagnostic information to the end user and installer when access is denied or the unit is operating offline. The
reader that is multiplexed into the alternate reader port will operate as the exit reader and the normal reader
connection shall be programmed to operate as the entry reader.
Warning:
Do not connect the shield to a AUX- or 0V connection.
Do not join the shield and black wires at the reading device.
Do not connect the shield to any shield used for isolated communication.
