5. Operational Information
The units should be no more than 300 meters from one another in
an open field.
The Far unit has one dipswitch with eight buttons, the default for
all of which is On. The end-user only uses button #7 to enroll the
Near and Far units. When the user turns button #7 to Off, the Near
unit recognizes the Far unit so the units work with each other.
The Far unit can also be attached to a REX (request for exit)
button, a door monitor to indicate whether a door is open or
closed, and a tamper to check whether the cover was opened.
These indications are transmitted from the Far unit to the Near unit,
which then sends them to the controller.
The proximity reader reads card information, and sends it from the
Far unit to the Near unit and to the controller to determine which
door to open. If applicable, the controller sends authorization to
open the door to the Near unit, which transmits the authorization
to the Far unit, and the door is opened.
