1. DESIGN AND APPLICATION
MCX402-BRD is I/O expander dedicated to the RACS 5 system. Depending on uploaded firmware the
expander operates with two Wiegand interface terminals or two PRT series terminals. After connection to
MC16 controller the device enables to control single door. The expander operates with backup battery which
can be charged with 0.3A current. MCX402-BRD expander is offered separately or as a component of
MC402-1-KIT and MC402-2-KIT.
Characteristics
RACS 5 system I/O expander
Power supply distribution for door devices
8 NO/NC inputs
2 transistor outputs
2 relay outputs
2 power supply outputs
Backup battery charging
RS485 interface
Wiegand interface
RACS CLK/DTA interface
Screw terminals
Power supply
The expander can be supplied with 24VDC or 18VAC and in such scenario it offers 13.8VDC power supply
outputs (AUX, TML) and backup battery charging. Alternatively the expander can be supplied with 12VDC
but then it does not offer power supply outputs and battery charging.
The expander charges backup battery with 300mA stabilized current up to 13.8V. Backup power supply is
activated automatically in case of main powers supply shortage. If the voltage at backup battery drops below
approx. 10V then the battery is automatically disconnected from expander and remains disconnected until
mains power supply returns.
Note: MCX402-BRD expander cannot be started using only power supply from backup battery.

RS485 bus
The communication method 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.
Wiegand bus
Wiegand interface can be used for communication with third party readers and terminals. Wiegand
communication is ensured via expander input lines (IN1-IN4) and up to two Wiegand terminals can be
controlled in such way by MC16 controller.
RACS CLK/DTA bus
The expander with factory uploaded firmware enables operation of Wiegand terminals with MC16 controller.
In case of PRT readers with RACS CLK/DTA interface the expander must be uploaded with new firmware
which is available at www.roger.pl. The expander enables the control of two PRT series readers with ID=0
and ID=1 addresses by MC16 controller.
LED indicators
Expanders are equipped with LED indicators which are used to signal integral functions.

Inputs
Expander offers 8 inputs (IN1 - IN8) of NO and NC type. Input types are defined within low level
configuration (RogerVDM). Input functions are assigned within high level configuration (VISO). Multiple
functions can be assigned to the same input at the same time.
Outputs
Expander offers two transistor outputs (IO1, IO2) and two relay outputs (REL1, REL2) with NO/NC contacts
and respectively 30V/1,5A and 230VAC/5A max. loads. 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.
Power supply outputs
Expander offers 2 outputs (AUX, TML) in order to provide power supply to terminals, door lock and other
external devices. Lines are protected respectively with 1.0A and 0.2A electronic fuses.
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.

Installation guidelines
All electrical connections should be done with disconnected power supply.
If the expander and controller are not supplied from the same PSU then GND terminals of both
devices must be connected with any wire.
3. OPERATION SCENARIOS
In typical scenario of operation, MCX402-BRD expander is used to control single door by MC16 controller.
Depending on uploaded firmware the expander can operate with 2 Wiegand or PRT terminals. In practical
applications expanders are usually installed within MCX402-1-KITs. The MCX402-2-KIT which is
additionally equipped with PS1A module can be used to control two read-in doors by MC16 controller.

Manual addressing
The RS485 address of expander configured with RogerVDM is a software address. Alternatively hardware
RS485 address can be configured with jumpers and such address has higher priority than software address.
Note: Each time the hardware RS485 address is modified the device must be restarted.
Fig. 9 Manual addressing of expander
Memory reset procedure
Memory reset procedure restores factory default settings including ID=100 software address.
Expander memory reset procedure:
1. Remove all connections from A, B, CLK and DTA terminals.
2. Place jumper on 64 contacts and restart device with RST button on device board or by switching supply
off and on.
3. Remove jumper from 64 contacts when LED STAT (red), LED OPN and LED SYS are ON.

MCX402-BRD Operating Manual 04.12.2020

4. LED OPN and LED SYS will switch off and device shall restart automatically with factory default
settings.
High level configuration (VISO)
The purpose of high level configuration is to define logical functioning of the expander which communicates
with the MC16 access controller and it depends on applied scenario of operation. The example of access
control system configuration is given in AN006 application note which is available at www.roger.pl.
5. FIRMWARE UPDATE
Factory new expander is equipped with a firmware dedicated to Wiegand readers. If the expander is to be
operated with PRT readers then another firmware must be uploaded. Such firmware is available at
www.roger.pl. Firmware update requires RogerISP program.
Expander firmware update procedure:
1. Connect the device to RUD-1 interface (fig. 8) and connect the RUD-1 to computer’s USB port.
2. Place jumper on FDM contacts
3. Restart device with RST button on device board or by switching supply off and on.
4. Start RogerISP software.
5. Select serial port emulated by RUD-1 interface and the option USB-RS485 Converter.
6. Select firmware file (*.hex), click Program and follow instructions on screen.
7. Once the firmware is uploaded remove the FDM jumper and restart the device.
8. Start Memory reset procedure.
