Page 2: Design And Application
2018-07-20 Design and application MCX4D is I/O expander dedicated to control four doors with MCT readers (RS485) in RACS 5 system. Additionally the expander operates as distributor of 12VDC power supply and RS485 bus. For each door the MCX4D offers two inputs, two outputs, RS485 interface, 1.0A main power supply and 0.2A auxiliary power supply. -
Page 3: Power Supply
PSxD series PSUs (Roger) are offered with two 30cm/1mm² cables dedicated to supply the expander. Multiple MCX4D 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 the battery cannot be fully charged and when the voltage is too high the battery can be damaged. -
Page 4: Backup Battery
Fig. 3 Two MCX4D expanders supplied from the same PSU Backup battery MCX4D 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. When battery voltage drops to approximately 10V then it is disconnected from expander. -

MCX4D Operating Manual.doc 2018-07-20 Fig. 4 Distribution of RS485 bus to MCT readers LCK and BELL outputs LCK and BELL are transistor (open collector) outputs which can control 15V/1.0A load. In standard scenario of door control, LCK output is dedicated to control door lock while BELL output is dedicated to control alarm signalling device and door bell but they can be used for any other functions which are configured using VISO management software. -
Page 6: Vout Power Output
The expander enables distribution of power and RS485 communication bus to four doors. For each door the MCX4D offers 1.0A power supply output (VDR+ and VDR- terminals), 0.2A power supply output (TML+ and TML- terminals), communication bus (RS485 A and B terminals), two programmable inputs (DC and DR) and two programmable outputs (LCK and BELL). -
Page 7: Connection Of Multiple Expanders To Controller
Fig. 6 Connection diagram for expander and MC16 controller Connection of multiple expanders to controller In the figure below an example of system including multidoor MC16 access controller and three MCX4D expanders is presented. In general perspective the maximal number of expanders connected to the controller equals the number of unoccupied addresses on RS485 bus. -

Fig. 7 Connection diagram for three MCX4D expanders and MC16 controller Configuration parameters In the table below the configuration parameters of MCX4D expander are presented. All settings are programmed with RogerVDM software within low level configuration of the expander. Note: Expander address can be also programmed manually within memory reset procedure. - Page 9 MCX4D Operating Manual.doc 2018-07-20 as above as above as above as above Parametric input resistance Tamper resistor Parameter defines the resistance [Ohms].

Page 12: Installation
Fig. 9 Connection of expander to RUD-1 (firmware update) Installation Enclosure with DIN rail is recommended for installation of MCX4D expander. All electric connections must be done without voltage on wires/terminals and with power supply disconnected. Optionally, DIN rail mounting clips can be removed and the expander can be installed on flat surface. It is recommended to install the expander in the same enclosure as PSU. - Page 13 MCX4D Operating Manual.doc 2018-07-20 Fig. 10 MCX4D board Battery charging settings 300 mA current recommended for 12V/7Ah battery 600 mA current recommended for 12V/17Ah battery 900 mA current recommended for 12V/24Ah battery LED signalling In Normal mode the LED signals lack of external power supply. In case of Memory reset the LED is used for manual addressing.
