In Magstripe format, the PRT12 reader transmits a sequence of data bits
representing either a code of the presented card or digits of entered PIN. When
operating with
Magstripe format, the reader stores all pressed keys in a buffer and
does not transmit them until the [#] key is pressed — a press of the [#] key is
treated by the unit as the end of the entered PIN code. The
Magstripe format does
not allow single digits of a PIN code to be transmitted separately after each
corresponding key-press.

When employing RACS transmission format, the PRT12 unit communicates with PR
access controller via CLK and DTA lines. Unlike in the
Wiegand and Magstripe
formats, the PRT12 unit using RACS format requires a individual address (ID=0…3)
to be set during configuration of the reader. With RACS format, communications
between the PRT12 and ACU is bilateral, this allows controller to monitor
communication. The reader’s LEDs and the buzzer are controlled by the host unit,
unless the reader has lost communication with a host.
Note: When all LEDs are flashing it indicates that the reader has lost
communication with the access controller.
When operating with RACS format, reader stores all pressed keys in a buffer and
does not transmit them, until the [#] key is pressed. Each entry of PIN code must
be followed by pressing the [#] key, which is treated as an end of PIN code. In
RACS format when IN1 is triggered, the PRT12 rejects any attempt to read a card
or to enter a PIN. This input can be used for disabling of a reader.
5.2. Offline Mode (Stand-alone Operation)
The PRT12 reader offers two variants of Stand-alone operation:
 Full Stand-alone mode
 Simple Stand-alone mode
In both operation modes the reader is capable of providing independent (i.e.
autonomic) control of a single door.

In this mode the reader’s CLK and DTA lines are used for communication with a
remote XM-2 I/O extension module and optionally with second (optional) PRT series
