2018-09-03 Design and application The MCX402DR-BRD is I/O expander dedicated to the RACS 5 system. The device is connected to MC16 access controller to provide control of 1 or 2 doors with Wiegand or PRT (RACS CLK/DTA) readers but in case of PRT readers new firmware must be uploaded to the expander.
MCX402DR Operating Manual.doc 2018-09-03 Fig. 2 MCX402DR-BRD application in single read-in/out door control (A) and two read-in doors control (B) Power supply and backup battery MCX402DR-BRD expander is designed for power supply from 230VAC/18VAC/40VA transformer and then it offers 13.8VDC power outputs (AUX, TML) for external devices. Optionally the expander can be supplied from 12VDC or 24VDC but in case of 12VDC the backup battery cannot be directly connected to the expander thus the emergency power supply must be provided by external PSU.

Fig. 4 MCX402DR-BRD supply from 12VDC or 24VDC Connection to RS485 communication bus MCX402DR-BRD is an addressable device and it must be connected to RS485 communication bus of the controller where MCT readers and other MCX expanders are usually also operated. Prior to connection, the expander must be assigned unoccupied address in range of 100-115.
MCX402DR Operating Manual.doc 2018-09-03 0.2A output is dedicated to supply readers. In the figure below a typical read-in/read-out door control scenario with MCX402DR-BRD expander is presented. The door system is supplied from the expander and it includes: 2 x PRT (RACS CLK/DTA) or 2 x Wiegand 26-66bit readers ...
MCX402DR Operating Manual.doc 2018-09-03 Device configuration The expander is configured within low level configuration by means of RogerVDM software. Such configuration must be done prior to connection to MC16 access controller particularly in regard of RS485 address and reader parameters. The address of expander can also be programmed manually with jumpers on expander’s board.

When low level configuration is finished then the expander can be connected to access controller in order to make functional configuration with VISO management software. Configuration parameters In the table below the configuration parameters of MCX402DR-BRD expander are presented. All settings are programmed with RogerVDM software within low level configuration of the expander. Configuration parameters...

MCX402DR Operating Manual.doc 2018-09-03 REL1,REL2 Parameter defines the polarity of output line. Output with normal polarity represents high impedance in normal state and is shorted to ground when triggered. Output with reversed polarity operates with inverted logic. It is shorted to ground in normal state and represents high impedance when triggered.
PRT readers then another firmware must be uploaded. Such firmware is available at www.roger.pl. Firmware update is also used in case of migration from RACS 4 to RACS 5 when PR411 and PR402 controllers are converted into MCX402DR expanders. Firmware update requires RogerISP program.
