1. DESIGN AND APPLICATION
MCX2D is I/O expander dedicated to RACS 5 system. The device after connection to MC16 access
controller and MCT series terminals enables to control 2 doors. The expander offers I/Os and distributes
power supply and RS485 communication bus. The expander operates with backup battery which depending
on particular requirements can be charged with 0.3A, 0.6A or 0.9A current. The expander is equipped with
removable terminal blocks which facilitate electrical connections during installation and maintenance.
MCX2D expander is offered separately or as a component of MC16-PAC-2-KIT.
Characteristics
RACS 5 system I/O expander
Power supply distribution for door devices
RS485 bus distribution for MCT terminals
4 parametric (EOL) inputs
4 transistor outputs
6 power supply outputs
Backup battery charging
RS485 interface
Removable screw terminals
Power supply
The expander requires 13.8VDC power supply and it is recommended to apply PS2D power supply unit for
that purpose. Due to relatively high current between expander and PSU, all connections should be made
using possibly short cables with adequate cross sections. PSxD series PSUs (Roger) are offered with two
30cm/1mm² cables dedicated to supply the expander. Multiple MCX2D expanders can be supplied from the
same PSU and in such case each connection must be made with individual pair of cables. When expander’s
supply voltage is too low then the battery cannot be fully charged and when the voltage is too high then the
battery can be damaged. MCX2D which is supplied from PSU equipped with own backup (e.g. UPS) can be
supplied with 12-15VDC but then it cannot be equipped with own backup battery.

Backup battery
MCX2D enables battery charging with 0.3A, 0.6A or 0.9A current up to the level of voltage supplied to the
expander (nominal 13.8VDC). The current is selected with jumpers (fig. 2). When battery voltage drops to
approximately 10V then it is disconnected from expander. The battery is reconnected when the 13.8V
supply to expander is restored. In order to ensure battery charging up to 80% level within 24h (according to
EN 60839 standard) following current settings must be applied:
300mA for 7Ah battery
600mA for 17Ah battery
900mA for 24Ah battery
RS485 bus
MCX2D is an addressable device connected to RS485 communication bus of the MC16 controller. At the
same time the expander distributes the bus to MCT terminals at each door. The expander can be operated
with default ID=100 address or it can be assigned with the address in range of 101-115. All devices on
RS485 bus of MC16 controller including MCX expanders and MCT terminals must have unique addresses
in range of 100-115. MCX2D is addressed within low level configuration by means of RogerVDM software or
manually within memory reset procedure.
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.
LED indicators
Expanders are equipped with LED indicators which are used to signal integral functions. According to further
mentioned procedures, the service mode is started by placing jumper on MEM contacts and restarting the
expander.

configuration (RogerVDM). Input functions are assigned within high level configuration (VISO). Multiple
functions can be assigned to the same input at the same time.
In standard scenario of door control, DC inputs are dedicated to connection of door contacts while DR inputs
are dedicated to connection of exit buttons and they do not require low level configuration as they can be
operated with default settings:
DC inputs: NC type / 50ms response time
DR inputs: NO type / 50ms response time
Table 2. 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:
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 (RogerVDM).
Transistor outputs
Expander offers LCK and BELL transistor outputs. Electric parameters such as polarity are configured within
low level configuration (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.
In standard scenario of door control, LCK outputs are dedicated to control door locks while BELL outputs
are dedicated to control alarm signalling devices and/or door bells. In standard scenario of operation both
LCK and BELL outputs do not require low level configuration.
Power supply outputs
Expander offers 6 outputs in order to provide power supply to access controller, terminals, door lock and
other external devices.
VDR outputs
VDR power supply output is dedicated to supply door lock, alarm signalling device and other door related
devices. The terminal VDR+ is protected with 1.0A electronic fuse. The terminal VDR- is internally shorted to
ground (GND). Green LED indicator is located at the VDR+ terminal to signal voltage at the output.
TML outputs
TML power supply output is dedicated to supply readers at door. The terminal TML+ is protected with 0.2A
electronic fuse . The terminal TML- is internally shorted to ground. Green LED indicator is located at the
TML+ terminal to signal voltage at the output.
VOUT output
VOUT power supply output is dedicated to supply additional electronic modules and it can be also used to
supply connected access controller. The terminal VOUT+ is protected with 0.2A electronic fuse . The
terminal VOUT- is internally shorted to ground. Green LED indicator is located at the VOUT+ terminal to
signal voltage at the output.
Note: If MC16 access controller is supplied from the expander then it cannot be at the same time supplied
by own PSU and it cannot operate with own backup battery.
AUX output
AUX power supply output is dedicated to supply optional electronic modules. The terminal AUX+ is
protected with 0.2A electronic fuse. The terminal AUX- is internally shorted to ground. Green LED indicator
is located at the AUX+ terminal to signal voltage at the output.
2. INSTALLATION
Each expander is equipped with a holder for installation on DIN35 rail. Therefore expanders can be installed
in ME type enclosures equipped with such rail. Alternatively, expanders can also be mounted using screws
and holes on expander board. It is recommended to install the expander in the same enclosure as PSU. The
cross section of power supply wires must be adequate as to avoid voltage drop greater than 200mV for
rated load. It is recommended to use cables with minimal 1mm2cross section and maximal 30 cm length.
Such cables are offered with PSxD series power supply units.

devices must be connected with any wire.
3. OPERATION SCENARIOS
In typical scenario of operation, MCX2D expanders are used in MC16-PAC-2-KIT two-door access control
kits (fig. 4 and 6). In the alternative scenario of operation, multiple MCX2D expanders are connected to
multidoor MC16 access controller (fig. 5). In such scenario the maximal number of expanders operated by
MC16 controller depends on its type and it is limited by available range of addresses ID=100-115 on RS485
bus of MC16 controller where all MCX and MCT devices must have unique addresses. For example, in case
of read-in/out doors it is possible to control max. 6 doors in such setup as MC16-PAC-6 + 3 x MCX2D + 12 x
MCT while in case of read-in doors it is possible to control max. 10 doors in such setup as MC16-PAC-10 +
5 x MCX2D + 10 x MCT. In both cases, 15 addresses on RS485 bus are occupied. It is also possible to mix
read-in and read-in/out doors within single MC16 controller if the limitation related to the number of RS485
addresses is preserved.
