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.
