The second function of the CCBR feature has to do with the role it plays in
upgrading software from an Option 11 or 11E to an Option 11C system. To
illustrate, if the CCBR feature is invoked in LD 43 of an Option 11 or 11E,
its configuration data can be backed up on a hard-drive of an external
computer. When the new Option 11C hardware is fully installed, and the
PCMCIA card is inserted in the System Core card, the backup copy of the
configuration data - stored on the computer - can be transferred back to the
upgraded Option 11C system as part of the software upgrade process.
Immediately upon download, the Option 11 or 11E database files will be
automatically converted to the Option 11C format.
Note: Whenever the CCBR feature is used, configuration data is always
backed up to the primary flash drive. Prior to invoking the CCBR
command, a data dump should be performed to ensure the primary
database is current.
Depending on the number of records in the configuration data base, it can take
over 30 minutes to backup or restore data at a rate of 1200 bps. CCBR access
time can be significantly decreased using a 19200 baud modem: 19200 baud
is the maximum data transfer rate supported by the Option 11C or Option 11C
Mini.
Communications software
Communications software compatible with XModem CRC protocol is
required to operate the CCBR feature. This requirement applies to on-site and
remote access.
On-site access
On-site access to the Option 11C or Option 11C Mini system can be made by
directly connecting a computer to SDI port 0, 1, or 2.
Note: You will need to connect a modem eliminator between the SDI
cable and the computer cable for on-site computer access.
