DigiReader Series
4 P/N 6600025, REV. BX
BASIC OPERATION
DigiReaders emit a low-level 140-kHz field. When a digital credential card is placed in this field, a
digital chip embedded in the key uses the fields energy to become activated. Once activated, the
key responds by broadcasting a 70-kHz signal, modulated with a key-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 Controller. The Controller identifies the digital credential according to its code and makes either
an access granted or an access denied decision.
DR4205K (/W) has a keypad on the face of the DigiReader. The key pad is used to enter the users
Personal Identification Number (PIN). (See the appropriate Controller or security management
system manual for details on PIN assignment.)
The user may enter his or her own PIN. The LED turns amber, and then the user presents a digital
credential; or the user may first present the key, the LED turns amber, and then the user enters the
PIN. The time allotted for this procedure is defined by the PIN GRACE PERIOD which is set with
the Controller SYSTEM command. (See the appropriate Controller or security management system
manual for information on setting this parameter.) If an error is made in entering the PIN, the user
may press the "*" key to clear the keypad and begin entry again.
The keypad versions can be configured for keypad-only use or credential-only use. Refer to your
controller manual or security management system manual for details on setup and configuration.
DR4200K is just the keypad part of the DR4205K.
LED OPERATION
LED (S-NET OPERATION)
When the DigiReader is on line, the LED is red during the ready state. The TUNE command is used
to specify LED and beeper behavior when a valid key is presented. An equivalent of the tune
command may be found in each WSE security management system system.
DigiReaders have a single three-color LED that can be controlled by the Controller. If power is applied
to the unit when not connected to a Controller, or improperly configured at the Controller, the LED
acts as follows: Flashes red four times in four seconds, changes to steady amber for four seconds
and then turns off for 52 seconds. When a key is presented, the sensor beeps four times, and the
LED flashes amber until the key is moved out of range. The flashing red, steady amber, off cycle
then resumes and repeats indefinitely while power is supplied.
