MCX4D 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.
12.11.2020 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 (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.

MCX4D Operating Manual 12.11.2020 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...
MCX4D Operating Manual 12.11.2020 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.

MCX4D Operating Manual 12.11.2020 Fig. 7 Connection to RUD-1 interface (low level configuration) Table 4. List of low level parameters Communication settings RS485 address Parameter defines device address on RS485 bus. Range: 100-115. Default value: 100. RS485 communication timeout [s] Parameter defines delay after which device will signal lost communication with controller.
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. F IRMWARE UPDATE The update requires connection of expander to computer with RUD-1 interface (fig.
