Cable Notes:
1. The individual wires coming out of the reader are color
coded according to the recommended Wiegand standard.
2. When using a separate power supply for the reader, this
supply and the controller's power supply must have a
common ground.
3. The cable shield wire on the reader should be attached to
an earth ground (best) or signal ground connection at the
panel or power supply end of the cable. This configuration
is best for shielding the reader cable from external
interference.
OPERATION INSTRUCTIONS
The reader should be tested after wiring it to a power supply
and the controller.
Do this by performing the following steps:
1. Power up the Reader. The LED flashes green on power up
(it may flash orange), and the Beeper sounds twice, at
which point it begins an auto-calibration procedure, this
can take up to two seconds, when the calibration is
complete a third beep will sound, thus indicating that the
Reader is working properly. The LED returns to its idle
state (red).
2. Present the appropriate type of proximity card to the
reader. The LED will momentarily flash green and a short
beep will be emitted. This indicates that the card was read
properly by the Proximity Card Reader.
3. After the card data is processed by the controller, the
controller can then turn the LED green. Refer to the
controller description of the LED operation if the reader
LED is controlled by the controller.
