If a PIN code is required, the green LED will flash while waiting to
receive the PIN code.
Card Read Operation: Each time the reader reads a smart card, the
yellow LED blinks off briefly and the beeper sounds. On systems
configured for PIN entry, the green LED flashes to indicate that keypad
data is expected.
PIN Code Entry: All PIN codes must be entered in this format:
* x x x x # This applies to Model 845 applicable modes only.
Reader Tamper Operation: The 84x Readers incorporate a tamper switch.
While the reader is separated from its backplate, all normal smart card
reading functions are disabled and a tamper condition is indicated by a
triple beep every 30 seconds. The red LED flashes quickly (every 400 ms)
and all communications with the microcontroller are suspended, taking
the reader off-line.
The reader is also equipped with an external tamper feature. To activate
this feature, connect a single-pole, single-throw (SPST), normally-closed
pushbutton switch (installer-supplied) to connector JP3 on the printed
circuit board assembly and install the switch between the wall and reader
backplate. When the reader and the backplate are removed from the wall,
the switch will close; therefore, closing the connection, causing a tamper
condition.
Door Contact and Exit Request Inputs: The 84x Readers have a
4-state supervised door contact switch input and an exit request switch
input. The state of both switch inputs is periodically reported to the
microcontroller, but changes to switch inputs are reported immediately.
Wiegand 4001 Mode Operation: The reader sends badge data to the
microcontroller after a valid MIFARE
presented to the reader. If Model 845 is used, the green LED will flash
waiting for a PIN code entry.
Unsupervised F/2F Mode Operation: The reader sends badge data to the
microcontroller after a valid MIFARE
presented to the reader. This communications mode does not support the
use of PIN codes.
Omron/Magstripe Strobe Mode Operation: The reader sends badge data
to the microcontroller after a valid MIFARE
is presented to the reader. This communications mode does not support
the use of PIN codes.
