1 – 2 : 12-24V DC (Power Input Terminals)
Connect the (+) to a 12-24V DC power supply or in parallel with the power supply of the master
keypad / reader. The (-) is the common grounding point of the system.
3 : Data I/O Bus
This is a data input-output bus compatible with the Data I/O bus of the DK-2800 keypads (the 2nd
generation or above) and the AR-2808 access control reader. Connect the Data I/O buses of the
reader(s) and keypad(s) in parallel.
4 – 5 : Tamper Switch
A Normally Closed (N.C.) dry contact while the reader is securely fixed on its back cover. The
contact is open while the reader is separated from the back cover. Connect this N.C. terminal to the
24 hour protection zone of an alarm system to make alarm in sabotage if required.
6 : LED Control Input Port
The Amber indicator is 0V (-) active by connecting the input terminal to (-) ground. It provides visual
feedback indication from the wiegand controller or the striking electric lock. It is for free connection.
(B) TERMINAL 7-10 FOR AR-2802A (ADVANCED VERSION)
7 : Buzzer Control Input Port
The internal Wiegand buzzer is 0V (-) active by connecting the input terminal to (-) ground. It
provides audible feedback indication from wiegand controller. Connect it to the output port of the
controller.

Remark:
Self-generated Feedback Tone ON-OFF Jumper:
The self-generated feedback tone of the reader may confuse
with the beeps feeding back from the controller in using
Wiegand data. The self-generated beeps can be selected for
ON-OFF with the jumper.
OPERATION
The auxiliary reader provides the output data faithfully from reading of an EM card. It uploads the
acquired data to the Data I/O bus to set up a communication path with the master keypad or reader.
The master keypad or reader interprets the data and executes the required function(s) accordingly.
The advanced version (version “A”) auxiliary reader also gives Wiegand and RS-232 data
simultaneously at separated output ports while it sends signal to the Data I/O bus.
Working with Master Keypad Via Data I/O Bus
● Read the EM card. The card’s ID will be sent to the master keypad or reader for verification.
● A valid user card (a registered card in the master) will be accepted. Two beeps confirm
....successful. The Green indicator turns ON and the Red indicator turns OFF for one second.
● An Invalid card (a card not registered in the master) will be rejected and five beeps indicate
....unsuccessful.
Working with Equipment via Wiegand and RS-232 Data (AR-2802A Only)
There is no audible feedback indication from the master keypad or reader if the reader only works
with an access controller using Wiegand and/or RS-232 data. Leave the Data I/O port open if it is
not used.
● Read the EM card. The card’s ID in Wiegand and RS-232 data format will be sent to the access
...controller and the PC respectively.
● The Wiegand and RS-232 data outputs are not affected by the card that is valid or invalid in the
...master’s registration. The reader sends the data out instantly if it is not a faulty card.
● The reader always gives 2 beeps to confirm a card is read. The Green indicator turns ON and the
...Red indicator turns OFF for one second during the data transmission.
● The on-board Wiegand LED and Buzzer are prepared for connecting with the access controller to
...get the visible and audible feedback indications. See terminals 6 & 7 for the connection details.
