1. DESIGN AND APPLICATION
The MCT82M-IO-HR is an access terminal dedicated to RACS 5 system. The device enables identification
of users by 13,56 MHz MIFARE® Ultralight/Classic/Plus/DESFire proximity cards. The terminal is mainly
dedicated to hotel applications and besides room entry control it enables the presentation of such hotel
signalizations with its LED indicators as Do Not Disturb, Make up the Room, Emergency Call and Service
Call. The device is offered in two versions: MCT82M-IO-HR for surface mounting and MCT82M-IO-HR-F for
flush mounting. The terminal is connected to access controller through RS485 interface.
Note: The application of RACS 5 system in hotels is explained in AN033 application note which is available
at www.roger.pl.

Power supply
The terminal requires power supply voltage in range of 11-15VDC. It can be supplied from MCX2D/MCX4D
expander of MC16-PAC-KIT, from MC16 access controller (e.g. TML output) or from dedicated power
supply unit. The supply wire diameter must be selected in such way that the voltage drop between supply
output and the device would be lower than 1V. The proper wire diameter is especially critical when device is
located in long distance from the supply source. In such a case the use of dedicated power supply unit
located close to the device should be considered. When separate power supply unit is used then its minus
should be connected to controller’s GND by means of signal wire with any diameter. It is recommended to
use UTP cable for connection of device to controller. The table below shows maximal UTP cable lengths in
relation to the number of wires used for power supply.

RS485 bus
The communication with MC16 access controller is provided with RS485 bus which can encompass up to
16 devices of RACS 5 system, each with unique address in range of 100-115. The bus topology can be
freely arranged as star, tree or any combination of them except for loop. The matching resistors
(terminators) connected at the ends of transmitting lines are not required. In most cases communication
works with any cable type (standard telephone cable, shielded or unshielded twisted pair etc.) but the
recommended cable is unshielded twisted pair (U/UTP cat.5). Shielded cables should be limited to
installations subject to strong electromagnetic interferences. The RS485 communication standard used in
the RACS 5 system guarantees proper communication in a distance of up to 1200 meters as well as high
resistance to interferences.
Note: Do not use more than single pair in UTP cable for RS485 communication bus.

Note: Synchronic pulsing of all four LEDs signifies lost communication with MC16 controller.
Buzzer
The terminal is equipped with buzzer which is used to signal integral functions and it can be additionally
programmed with other available functions within high level configuration (VISO).
Inputs
The terminal offers 3 general purpose parametric inputs of NO, NC, 3EOL/DW/NO and 3EOL/DW/NC type
and 1 input internally connected to tamper contact. Input types and electric parameters such as response
time and parametric resistors are defined within low level configuration (VISO v2 or RogerVDM). Input
functions are assigned within high level configuration (VISO). Multiple functions can be assigned to the
same input at the same time.

Table 3. Input types
NO input
NC input
NO input can be in normal or in triggered state. In
normal state CAcontacts are opened. Input
triggering is caused by CAcontacts closing.
NC input can be in normal or in triggered state. In
normal state CAcontacts are closed. Input triggering
is caused by CAcontacts opening.
3EOL/DW/NO input
3EOL/DW/NC input
3EOL/DW/NO input is operated in such way that CA
contacts closing is interpreted as triggering of the
first input while CBclosing is interpreted as
triggering of the second input. In VISO software DW
input type is represented by two independent inputs.
Each can be used for different purpose and
assigned with different function.
3EOL/DW/NC input is operated in such way that CA
contacts opening is interpreted as triggering of the
first input while CBopening is interpreted as
triggering of the second input. In VISO software DW
input type is represented by two independent inputs.
Each can be used for different purpose and
assigned with different function.
Parametric resistors
The same values of parametric resistors are used for all inputs i.e. 1kΩ; 1,2kΩ; 1,5kΩ; 1,8kΩ; 2,2kΩ; 2,7kΩ;
3,3kΩ; 3,9kΩ; 4,7kΩ; 5,6kΩ; 6,8kΩ; 8,2kΩ; 10kΩ; 12kΩ. In case of 3EOL/DW (Double Wiring) input type,
Alarm A resistor defines a value of resistor used to detect triggering of the first input while Alarm B resistor
defines a value of resistor used to detect triggering of the second input. Alarm A resistor value must differ
from value of Alarm B resistor at least by three positions in the list above. Total resistance of wire used to
connect contacts to input should not exceed 100 Ω. Default values of parametric resistors:

MCT82M-IO-HR Operating Manual Rev. D.doc 22.06.2021
6/17
Alarm A = 2,2 kΩ
Alarm B = 5,6 kΩ
Response time
Response time parameter defines minimal impulse time on the input which triggers the input. Each input can
be configured individually in range of 50 to 5000 ms within low level configuration (VISO v2 or RogerVDM).
Tamper detector
Built-in tamper (sabotage) detector enables detection of unauthorized opening of device’s enclosure as well
as detachment of the enclosure from wall. The detector is internally connected to the terminal’s input. It
does not require low level configuration or any additional installation arrangements but it is essential to
mount front panel in such way as the tamper detector (fig 4) would firmly press the back panel. The detector
requires high level configuration which consists in assignment of the function [133] Tamper Toggle on the
level of a Main Board of a controller in VISO software navigation tree.
Outputs
The terminal offers 2 transistor open collector type outputs (15V/150mA rated) and 1 relay output with
NO/NC contacts (30V/1.5A DC/AC rated). Electric parameters such as polarity are configured within low
level configuration (VISO v2 or RogerVDM). Function are assigned to outputs within high level configuration
(VISO). Multiple functions with different priorities can be assigned to the same output at the same time.
Identification
By default the terminal reads serial numbers (CSN) of MIFARE cards but it is possible to program cards with
own numbers (PCN) in selected and encrypted sectors of card memory. The use of PCN prevents card
cloning and consequently it significantly increases security in the system. More information on MIFARE card
programming is given in AN024 application note which is available at www.roger.pl.
The technical characteristics of the device are guaranteed for RFID cards supplied by Roger. Cards from
other sources may be used, but they are not covered by the manufactures warranty. Before deciding to use
specific Roger products with third-party contactless cards, it is recommended to conduct tests that will
confirm satisfactory operation with the specific Roger device and software in which it operates.

Installation guidelines
The terminal should be mounted on a vertical structure (wall) away from sources of heat and
moisture.
Front panel should be attached in such way as the tamper detector (fig. 4) would firmly press the
back panel.
All electrical connections should be done with disconnected power supply.
If the terminal and controller are not supplied from the same PSU then GND terminals of both
devices must be connected with any wire.
Device can be cleaned by means of wet cloth and mild detergent without abrasive components. In
particular do not clean with alcohols, solvents, petrol, disinfectants, acids, rust removers, etc.
Damages resulting from improper maintenance and usage are not covered by manufacturer
warranty.
3. OPERATION SCENARIO
The terminal when connected to MC16 access controller can be used for access control, especially in case
of hotel room. The example of connection diagram for such scenario is shown in fig. 7 where the terminal’s
power supply line and RS485 bus are connected directly to the controller. The terminal can also operate
with MC16 controller using MCX2D/MCX4D expanders as in case of M16-PAC-KIT series.
Fig. 7 Typical connection diagram for the terminal and MC16 access controller
4. CONFIGURATION
The purpose of low level configuration is to prepare device for operation in RACS 5 system. In case of
RACS 5 v1 system the address of device must be configured by means of RogerVDM software or by
manual addressing before connection to MC16 controller. While in RACS v2 system, low level configuration
and addressing can be done with VISO v2 software during final configuration of the system. Therefore in
RACS 5 v2 system the configuration from RogerVDM software and manual addressing are optional and
during installation it is only necessary to properly connect the device to MC16 access controller.
Low level configuration (VISO v2)
In RACS 5 v2 system the reader can be installed at site without previous configuration. According to AN006
application note, its address and other settings can be configured from VISO v2 management software and
during such configuration the access to its service contacts (fig. 4) is not required.
