When employing RACS transmission format, the PRT32 unit communicates with PR
access controller via CLK and DTA lines. Unlike in the Wiegand and Magstripe
formats, the PRT32 unit using RACS format requires an individual address
(ID=0…3) to be set during configuration of a reader. With RACS format,
communications between the PRT32 and ACU is bilateral, this allows controller to
monitor communication. The reader’s LEDs and the buzzer are controlled by the
host except situation when reader will lost communication with host. In this case
are LEDs are flashing which means that communication between reader and host is
discontinued.
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 the end of a PIN code. In
RACS format when IN1 is triggered, the PRT32 will stop reading cards and PINs till
the moment when IN1 will be released.

Offline Mode (Stand-alone Operation)
The PRT32 reader offers two variants of Stand-alone operation:
•
Full Stand-alone mode
•
Simple Stand-alone mode
In both operation modes 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
reader (for two-way door control). The IN1 line operates as a programmable input
and can be configured to various options. The I/O lines on the XM-2 module can be
programmed to several predefined functions (see: settings for C5, C6, C7, C8 and
C9 parameters in section Installer Programming). The Full Stand-alone mode offers
improved security, because it allows for separation between the reader and the
relay which controls a door lock.
