Functional description
The readers are designed for contactless identification of Novar transponders data carriers e.g. ID
chipcards, possible data carriers see Chapt. 9 "Accessories").
A combination of transponder and PIN can be used for performing functions via the keypad.
The transmitted code is prepared in the reader so that the connected AC
can
continue the processing e.g. switching and control functions.
Communication between the reader and AC
is via an RS-485 bus or Clock/Data
interface.
(
In order to read a transponder an electromagnetic field with a frequency of 125 kHz is transmitted
from the reader unit. As soon as a transponder enters this field, it transmits a code in the "power
field" to the reader.
The individual code of every transponder renders it unique.

The state is indicated via 3 LEDs (ready, authorized, not authorized). A buzzer is integrated for
acoustical acknowledgement.
