Issue Can the I/NET SCU controller connect to Security Expert SP-C directly instead of being imported from the I/NET system?

The configuration parameters for each door controller gets stored in the 779x  host device, then the host device’s data is saved to a SAV file (i.e., a backup file of the 779 x  device). To integrate I/NET door controllers with Security Expert, The subLAN (779x  host device ) is then disconnected from the door controllers and connected to an SP-C (the SP-C replaces the 779 x  host device). The 7798x  host device’s SAV file is then downloaded to the SP-C as a binary blob.  The SP-C needs this SAV file to know how to communicate with each door controller and to configure these devices if a cold restart is ever experienced. ...
