DCM
■ Overview
DCM (Device Configuration Management) is a function to migrate the setting values (of user
mode and service mode). In terms of the description in the User’s Guide, it is synonymous
with "Import/Export All". Service mode setting values can be backed up/restored from the top
screen of service mode.
By the conventional method for backing up SRAM of the Main Controller 2, data could be
backed up/restored only for the same machine. DCM supports the following 3 patterns.
• The same machine (backup for the purpose of providing against emergency)
• A different machine of the same model (setting values are migrated collectively to multiple
machines when replacing a host machine)
• A different model (e.g.: the setting values are copied from an old model to a new model)
● Where data is stored
Store the backup data in the following location.
• User > PC (RUI)
• Service > USB memory device/HDD of the machine (top screen of service mode)
●
Setting values that can be backed up
The values changed by the user under [Settings/Registration] and those specified in service
mode can be backed up.
Only setting values are backed up. Image data such as scanned image cannot be backed up.
• Setting values under [Settings/Registration]
• Service mode setting values
● General limitations on DCM
• With iR-ADV C52xx series, service mode for FAX cannot be migrated.
• With DCM, stored data, MEAP application, and system option license cannot be migrated.
• A .dcm file exported to the internal HDD is not deleted even when the machine is restarted.
Only 2 files at a maximum are stored in HDD. When there are more than 2 files, the old
.dcm files are deleted from the oldest.
• Continuous import is not guaranteed. After importing a file, the machine must be restarted.
If executing import without restart, NG is displayed and a file is not imported.
• When importing DCM file in service mode and user mode separately, perform it in the
following procedures.
1) Perform the import of the DCM data of the service mode earlier.
2) Reboot the Host machine.
3) Import the DCM data of the user mode.
• As for service mode, if the process is not completed within 5 minutes in the case of export
and 15 minutes in the case of import, the item performed at that time is continued until it
ends, but the final result becomes ERROR.
• Data to which no password is set when exporting service mode cannot be loaded from
collective import from RUI. When assuming to perform collective import from RUI,
password must be set to data to be exported.
• Following limitations are applied to password for DCM data:
• Character string of software keyboard: 0 to 32 characters
• No password is set when 0 character is entered. (The setting in which no password is
set is allowed only for service mode.)
• No space is allowed in the middle of a password.
• Password is case sensitive.
• At the time of following setting, Host matchine does not recognize USB memory.The DCM
function is not usable, too.
• Settings/Registration > Preferences > External Interface > USB Settings > Use MEAP
Driver for External USB Device = On
● Restrictions about import/export
• An import/export process ends with error while the following specific job is executed;
• Send job,
• Forwarding job,
• FAX reception job,
• IFAX reception job
• If this function is executed with a print job simultaneously, it affects the operation such as;
UI is locked, or a print job is cleared by reboot after import. So it requires careful operation.
• A device rejects an import/ export request during shut-down.
• If this function is executed with device information distribution or RUI import/ export
(conventional function) simultaneously, the first coming job takes priority and they are
controlled exclusively.
• If this function is executed with a firmware update by a CDS Updater simultaneously, a
firmware update process takes priority, and this function is stopped temporarily by reboot.
• When error code is issued, this function ends with error.
• If the display language differs between export and import, a setting value of a text corrupts
in some cases. The character corruption can be solved by changing the display language
to the appropriate one.
