Fig. 10 Connection of PRT series readers and XM-2 expander
Note: Practically, devices communicating in RACS CLK/DTA standard (e.g. PRT readers) can be
connected to the controller for significantly greater distances than 150m (even up to 500m), but
the communication in such distance is not guaranteed by the manufacturer.
3.6.2 PRT and third party readers (Wiegand)
The connection of Wiegand readers is shown in fig. 11. Wiegand interface readers can be
connected to controller along with PRT series readers connected to CLK/DTA lines. When so, users
can authorize alternatively on PRT or Wiegand reader. In case of Wiegand/Magstripe readers it is
necessary to select adequate data format, otherwise controller will not recognize transmissions
from the reader. Data format can be selected by means of PR Master software. If particular
Wiegand reader does not work properly with the controller, it might be necessary to use PR-GP
module. The PR-GP works as electrical interface between reader and controller. In order to
determine if PR-GP might be useful, please contact Roger technical support.

3.7 Input and output lines
Functions are assigned to inputs and outputs by means of PR Master software or by means of
manual programming (keypad commands). Default function for REL1 relay output is door unlock.
