Design and application
The MCX16-AP I/O expander enables use of APERIO (ASSA ABLOY) wireless locks as access terminals in
RACS 5 system. MCX16-AP operates as hardware interface for communication of APERIO locks with MC16
access controller. The expander communicates with the MC16 controller using RS485 bus and with
APERIO system using Ethernet (LAN). MCX16-AP offers its input and output lines for use in RACS 5
system.
Note: Additional information on configuration of RACS 5 and Aperio (ASSA ABLOY) integration is given in
AN034 Application note which is available at

License
The factory new expander comes with the original factory license which is kept in MCX16AP.LIC file on
memory card. The content of the file specifies the maximal number of operated APERIO locks. The license
file is generated individually for every expander and will not work with another expander. In case of license
upgrade it is necessary to replace license file with the new one. It is recommended to make backup copy of
memory card and use it when necessary to restore lost data. Once the new license is saved on the card it is
