BASIC OPERATION
DigiReaders emit a low-level 140-kHz field. When a digital credential (card, KeyMate™, DuraTag™,
etc.) is placed in this field, a digital chip embedded in the credential uses the field’s energy for
activation. Once activated, the credential responds by broadcasting a 70-kHz signal, modulated
with a credential-specific code sequence, back to the reader. The reader receives this signal and
converts it to a digital code which is then sent to the ACU, (the Controller). The Controller identifies
the digital credential according to its code and makes either an access granted or an access denied
decision, based on credential information stored in the Controller's database or the host system's
database.
The DR4205K has a keypad on the face of the DigiReader. The keypad is used to enter the user’s
Personal Identification Number (PIN). The DR4205K keypad version can be configured for credential-
only use, or keypad-only use, or both, from the ACU DOOR Command. If the S-Net Reader Type
entry is set to DKR, the credential use will be activated for that door; set to NONE, the credential
use for that door will be de-activated; (
–
this is true for all DigiReaders except the DR4200K). For
the same door/reader combination, if the VIP Enable is set to Yes or No, the keypad portion will be
activated or de-activated, respectively.
The DR4200K is a keypad-only reader look-alike of the DR4205K, activated from the ACU DOOR
Command by setting VIP Enable (for that door) to Yes.
LED (AND BEEPER) OPERATION
LED (AND BEEPER) (S-NET OPERATION)
All DigiReaders have a single three-color (red-amber-green) LED controlled by the Access Control
Unit (ACU) to which the DigiReader is attached. Figure 2 shows the location of the LED on each
of the DigiReader models.
With the DigiReader on line to an ACU and with power applied, (the ready state), the DigiReader's
LED will be a constant red. When a DigiReader is configured to read digital credentials only (with
no keypad part of the DR4205K or VIP2 or DR4200K activated for the same door), a valid credential
will produce a momentary amber LED, followed by a green LED for the door unlock time or until the
door is closed following the credential-holder's access; (the LED will then return to the constant red).
With a keypad also activated, the amber LED will continue until either both the valid digital credential
and valid PIN, in either order, have been read/entered, producing the green unlock time LED, or until
the PIN grace period has been exceeded, producing the red LED. With only the keypad activated,
a valid PIN will produce the momentary amber, the unlock green and the return to the constant red.
