4.3.16. Backing up Important Setting Data
(1) Purpose
“Important setting data (setting information which differs for each customer.)” is backed up to
floppy disks and hard disks in consideration of possible setting data loss, hard disk corruption
or other data errors.
In the event that setting data is lost or the hard disk is corrupted, this “Important setting data”
can be quickly restored to the condition before the trouble occurred by copying from the
backup data.

Notes
1) Performing this backup work means that the CXDI system will be used with the floppy disk
inserted in the floppy disk drive.
When changing the layout or otherwise moving the control PC, be sure to first eject the
floppy disk to avoid damaging the floppy disk drive.
Likewise, when mounting the system in a vehicle, vibrations may cause damage to the
floppy disk drive.
Therefore, after backing up the latest data to the floppy disk, be sure to eject the floppy
disk.
2) Based on the reason in note 1) above, do not perform backups in an environment that is
exposed to vibrations. Therefore, never perform backups when the control PC is loaded in a
car.
In V4.0 and later versions, the default FD-Buck Up setting is ON. When backup to a floppy
disk is not allowed, set it to OFF.
3) In the product default settings, “Boot/1. Removable Device” in the system BIOS settings is
set to “Disabled”. However, as a precaution, check that “Boot/1. Removable Device” is
actually set to “Disabled”. If the setting is changed to “Legacy Floppy”, the control PC may
not start properly when a floppy disk is inserted.
For more information, see “System BIOS Settings”
4) Be sure to always format the floppy disk that you are using before performing backups.
5) The backup procedure described here covers the case when backing up for the first time
after installation. For the second and subsequent times, data is automatically backed up to
the floppy disk whenever the user selects backup. It is recommended that you make a
backup whenever changing the exposure mode buttons or other settings.
