Design and application
LRT-1 is a long range proximity card reader. The reader is offered in a set with MCI-1 interface which
enables connection of the reader both to MC16 series access controllers (RACS 5 system ) and
PRxx1/PRxx2 series access controllers (RACS 4 system). In all scenarios the reader sends 32bit card
number. LRT-1 enables EM125kHz proximity card reading in distance of 1 m. The reader can be installed
outdoors.
Power supply
LRT-1 and MCI-1 require 11-15VDC power supply. Devices can be supplied directly from the access
controller (e.g. TML output) or from dedicated power supply. Due to relatively high supply current (300mA),
wire diameter must be selected in such way that voltage drop between supply output and the reader is less
than 1V. The proper wire diameter is especially critical when reader is located in long distance from the
supply source. In such a case the use of dedicated power supply located close to the reader should be
considered. When local power supply is used then its negative terminal should be connected to COM
terminal of MCI-1 by means of signal wire with any diameter.
Note: Interferences in supply voltage may reduce reading range. In case of LRT-1 it is recommended to use
power supplies which generate low level interferences, preferably analogue power supply units.

Reading range
In optimal conditions, the LRT-1 enables reading of EM125kHz proximity cards from the distance of 95cm.
Such range is possible for ISO card of EMC-3 type (Roger) and for optimal orientation of card at the reader
and without electrical interference in vicinity of the reader. Metal objects close to the reader and electrical
interferences may reduce reading range. Metal objects are irrelevant if located in distance of more than 1m
from the reader. In case of LRT-1 installed in distance of 15 cm from metal wall the reading range is
approximately reduced by 50%. If the distance is 25cm then the range is reduced approximately by 15%. If
the reader is installed in a distance lower than 15 cm from metal wall then card reading might be not
possible at all. If the LRT-1 is mounted on metal pole with maximal cross section of 10x10 cm then reading
range is reduced by 15%.
Note: Reading range may be slightly reduced (approx. by 5%) if supply voltage is in range of 11-12V. Such
reduction results from device design.
Note: Every time the LRT-1 power supply is restored, the device calibrates its antenna circuit to adapt to
metal object in its vicinity. If metal objects size or location is changed during the operations of LRT-1 then
the reading range may be reduced. Therefore in such situation it is recommended to restart the reader to
perform automatic calibration procedure.
Service contacts
MCI-1 interface is equipped with service contacts which are used for device programming and servicing.

LED indicators
LED indicators are located inside the enclosure of MCI-1 and they are visible from the top of the interface.
LED indicators are used to signal various states both in programming and normal modes. Communication
loss with controller is signalled with synchronic pulsing of all indicators.

Address programming
The address of MCI-1 interface must be configured both for operation in RACS 4 and RACS 5 system. The
address can be programmed manually (without computer) or with RogerVDM software. In case of operation
in RACS 4 system the address range is 0-3 while in RACS 5 the address range is 100-115.
Note: In case of manual address programming for operation in RACS 5, the first digit of address is skipped.
Manual address programming:
Switch power supply off
Place jumper on MEM contacts
Select RACS 4 operating mode on MD1 and MD2 contacts (table 2)
Connect CLK/A terminal with DTA/B terminal
Switch power supply on
LED_ST (red) indicator will pulsate
Disconnect CLK/A and DTA/B terminals
Count the number of LED_SY (orange) pulses and switch power supply off when the number of
pulses equals to desired address
Remove jumper from MEM contacts
Switch power supply on and connect the interface to controller
Note: The address 100 (for RACS 5) or 0 (for RACS 4) is programmed with 16 pulses of LED_SY (orange)
indicator. After 16 pulses, LED_SY lights steady on and LED_ST (red) pulsates. Remove jumper from MEM
contacts then and restart power supply.

MCI-1 operating mode
LRT-1 reader can be used both in RACS 4 and RACS 5 systems. The selection of operating mode is done
with MD1 and MD2 contacts.
Contacts
Function
RACS 4 operating mode. The MCI-1 interface is connected to RACS CLK/DTA bus (CLK
and DTA terminals) of PRxx1 or PRxx2 access controller
RACS 5 operating mode. The MCI-1 interface is connected to RS485 bus (A and B
terminals) of MC16 access controller
Tab. 3 Selection of MCI-1 operating mode
The reader when operated in RACS 4 and RACS 5 system returns 32bit proximity card number (instead of
typical 40bit number). Therefore some additional configuration steps are necessary to adapt both RACS
systems to operation with LRT-1.
In RACS 4 system it is necessary to select the option 24 bit (reduced card number) in PR Master software
(PRMaster/Tools/Options/Cards). In RACS 5 system it is necessary to additionally define and assign 32bit
type Authentication Factor for each user who will identify at LRT-1. Alternatively all Authentication Factors
used in the system could be defined as 32-bit type and then no additional factors for LRT-1 are necessary.

Connection to access controller
Select operating mode with MD1 and MD2 contacts and define address prior to connection of MCI-1
interface to access controller. The address must be in range of 100-115 (RACS 5) or 0-3 (RACS 4). The
address can be programmed manually while all low level settings can be configured with RogerVDM
software. LRT-1 reader must be connected to MCI-1 interface with UTP cable. Unused wires of the UTP
cable can be used for power supply.
