SK-ACP Installation & Operating Manual
C-1
APPENDIX C
The SK-MDM Modem (Best Data Smart One 56SPX) has been selected by Secura Key for use with 28SA-
Plus Access Control Unit and the SK-ACP at remote locations. The SK-MDM is connected directly to the
RS232 port of a 28SA-Plus or an SK-ACP.
The 28SA-Plus and SK-ACP contain the configuration data or “setup string” for the SK-MDM, which allows
the modem to be configured in the field by the reader without the use of a computer, and without setting
DIP switches.
Note that the setup string stored in the 28SA-Plus and SK-ACP is only used for modems at remote locations.
If you are using a SK-MDM at the PC location, use the setup information provided with the modem for
installation with your PC.
