1. INTRODUCTION
1.1 This manual
This manual contains minimum information that is necessary to properly install the device and to
perform initial tests. Full functional description of the controller has been included in the document
- PRxx2 series controllers, Functional description and programming guide. Whereas PR Master
software, which is used for access control system management is described in detail within the
manual for that software. Both documents are available at www.roger.pl.
2. DESCRIPTION AND SPECIFICATION
PR602LCD controller belongs to advanced PRxx2 series. The new, factory-made controller has the
address ID=00 and is equipped with the MASTER card. PR602LCD is also equipped with built-in
reader of EM125kHz standard, so the MASTER card can be used for the initial tests after
installation. The controller has also LCD, numeric keypad and functions keys. Therefore PR602LCD
is recommended for Time&Attendance applications. Additional external reader can be connected to
the controller if it is required to provide access control at both sides of the door.
Two versions of PR602LCD are available: PR602LCD-I can be installed only indoors while
PR602LCD-O can be installed outdoors and no special protection against rain and moisture is
required.
The controller can be programmed by means of computer with PR Master software. PR602LCD can
be connected to PC by means of communication interface i.e. UT-2USB, UT-4DR or RUD-1.

3.2 LED indicators
PR602LCD controllers are equipped with 3 LED indicators. Their functions and colours are specified
in table 3 below. Functioning of LEDs can be verified by means of included MASTER card.

3.3 Power supply
The controller requires 12VDC nominal power supply. The power should be connected to the +12V
line and GND line. Additionally, the GND line can be used as reference potential for the RS485 bus,
IN1-IN3 input lines and RACS Clock&Data bus.
The power supply can be provided by means of power supply unit PS10 or PS20, which are
available in Roger offer. The power supply units can be connected to backup battery in order to
ensure operation of access control in case of power failure.
All devices connected to RS485 bus (including controllers) should have common supply minus
(GND). In order to ensure this, all the GND terminals from various power supply units within the
system should be connected with each other using separate wire. Alternatively, the common supply
minus (GND) of the entire system can be earthed however in one, arbitrary selected point only.
3.4 Connection of door locking device
In majority of cases, door locking devices are inductive type. It means that turning off the current
flow through the device causes the over voltage condition (voltage surges) which can interfere with
the controller electronic components. In extreme cases it may result in improper operation of the
controller or even freeze of the unit. Moreover, overvoltage condition causes quicker wear of the
relay contacts. In order to limit this negative condition, it is necessary to use a general type
semiconductor diode e.g. 1N4007 (one piece of such diode is included with the controller). It should
be connected as close as possible to the inductive element (electric strike or magnetic lock).

3.5 Connection of external reader and/or extension modules
PR602LCD controllers are equipped with built-in reader (Terminal ID1) for EM 125kHz (UNIQUE)
proximity cards and can operate with additional external reader (Terminal ID0), thus creating two-

Page 7of 15
way door control. Any PRT series readers configured to RACS Clock&Data mode with ID=0 address
and connected to CLK and DTA lines or any Wiegand/Magstripe reader also connectedto CLK and
DTA lines can operate as Terminal ID0. All readers can be activated or deactivated in
within configuration software (PR Master)
3.5.1 PRT series readers and extension modules
PR602LCD controller is equipped with built-in reader for EM125kHz (UNIQUE) proximity cards and
can operate with XM-2 module and up to four XM-8 modules dedicated to access control in
elevators. The address of external reader must be ID=0 (i.e. factory default address of PRT
reader), the address of XM-2 must be ID=5 and addresses of XM-8 modules must be in range of
ID=8..11. All mentioned device must be connected to CLK and DTA lines of the controller. Any type
of cables (e.g. unshielded twisted pair) can be used for CLK and DTA lines. Guaranteed
communication distance is 150 meters.
Note: Practically, devices communicating in RACS Clock&Data standard (e.g. PRT readers) can be
connected to the controller for distances up to 500m, but it is not guaranteed by the manufacturer.

3.5.2 Wiegand and Magstripe readers
PR602LCD controller can operate with various Wiegand type readers which transmit 26 to 66 bits of
data in different data formats and with Magstripe readers. Botj types of readers should be
connected to PR602LCD controller in accordance with diagram shown in fig. 4.
Note: When working with 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.
Note: If particular Wiegand/Magstripe 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.

3.6 Input and output lines
Functions are assigned to input and outputs by means of PR Master software. Default function for
REL1 relay output is door unlocking.
3.6.1 Inputs
All inputs (IN1-IN3) of PR602LCD controller have identical electric structure and can be configured
as NO or NC lines. The NO input is triggered by shorting it to supply minus (GND) while the NC
input must be normally shorted to supply minus (GND) and it becomes triggered when connection
with ground is discontinued. Every input is internally connected (pulled up) to the power supply
plus (+12V) through a 5.6kΩ resistor.
3.6.2 Relay outputs
The relay output REL1 offers one switched contact rated 30V/1.5A. The relay contacts are internally
protected against overvoltage by semiconductor elements. However this does not release the
installer from responsibility to eliminate interferences from inductive elements by an additional
diode. It is forbidden to use relay output to switch voltages above 30V because this for sure will
cause damage to the semiconductor elements protecting the relay’s contacts. In the normal state
(the relay is off) the NC-COM contacts are shorted. In the triggering state (the relay is on) the NO-
COM contacts are shorted. In case of lack of the power, the REL1 output is in the off state.
3.6.3 General purpose outputs
Two transistor outputs (IO1, IO2) are available in PR602LCD controllers. All these lines are open
collector type, i.e. in the normal (off) state are pulled to supply plus via 5.6kΩ resistor and when
on, they short to supply minus. Both lines can switch current up to 1A DC while voltage connected
to the output must not exceed 15VDC. In case of overcurrent state, transistor outputs are
automatically switched off and the controller automatically restarts.
3.7 RS485 communication bus
The RS485 bus consists of two signal lines A and B. In the RACS 4 system any topology can be
used (star, tree or any combination of them, except for loop) in order to connect controllers in
subsystem and to establish access control system. The matching resistors (terminators) connected
at the ends of transmitting lines are not required. In most cases communication works with any

Page 9of 15
cable type (standard telephone cable, shielded or unshielded twisted pair etc.) but the
recommended cable is unshielded, twisted pair (UTP). Shielded cables should be limited to
installations subject to strong electromagnetic interferences. The RS485 communication standard
used in the RACS 4 system guarantees proper communication in a distance of up to 1200 meters as
well as high resistance to interferences. UT-4DR communication interface can be used for
communication of computer and PR Master software with remote (more than 1200m distance)
RACS 4 network (subsystem) of controllers. UT-4DR enables the communication through LAN/WAN.
