Database Backup Procedure
Upgrading the program in the MicroVission panel
normally involves replacing the SD card. Note that all
compressor operation setpoints, calibration values
and maintenance information is stored on the SD card.
So, when upgrading to a new program (new SD card),
the task is simplied by using the “Database Backup”
and “Database Restore” functions provided in the
MicroVission to migrate the database of the original SD
card to the new SD card.
There are three main steps to this process:
1. Backup the database of original SD card (currently
in the MicroVission panel) – onto a thumb drive or
ash drive.
2. Replace the original SD card with new SD card.
3. Restore the original database to new SD card.
Backup Database of Original SD Card
NOTE
It is REQUIRED to manually reenter the Alarms and Trip
settings when upgrading from some older version of
programs. Therefore, it is highly recommended to cre-
ate a hardcopy of all compressor operating setpoints, or
to create and have handy a printout of the Setpoints Re-
port .csv le.
It is also recommended to make a hardcopy of the con-
guration information and maintenance information
prior to changing SD cards. For the list of all the informa-
tion that you should record, see the “Record operating
setpoints and conguration information” section below.
The data migration procedure (moving the original SD
card database to new SD card) uses a “thumb drive” or
“ash drive” to transfer data from the original SD card
to the new SD card. Note there have been a few re-
cords of some thumb drives not being recognized by
the MicroVission. If you have difculty in getting the
MicroVission to recognize the thumb drive – then try a
different one. Vilter has successfully tested many differ-
ent manufacturers and sizes; a partial list is given below:
• SanDisk micro cruzer 2.0 GB
• Imation 2.0GB
• Kingston DataTraveler 512 MB
• SanDisk mini cruzer 128 MB
1. With the original SD card installed into the
MicroVission SBC, insert the ash drive into the USB
port. This port is located along the left side of the
single board computer above the ethernet connec-
tor. See Figure 13-4: SD Replacement.
2. Log into the MicroVission using your username and
password (you will need to be Level 3 to upload
data).
3. Navigate to the Data Backup screen.
4. In the “Available Devices” window, you should see
something like “/media/usb0”. If you do not see
anything in this window, press the “Refresh” button,
and wait about 5 seconds. After that press the but-
ton again. If you still do not see the device, then the
MicroVission does not recognize the ash drive - try
a different one. If you do see it, highlight it.
5. Now highlight the “Filename” eld (which will also
contain “/media/usb0”). A keyboard will appear.
Now type in the name of the le that you want for
your database for this compressor. For instance,
“cylinders_month_day_year” or something similar
for identifying the le to the compressor. Then press
“Enter” key on keyboard.
6. Now press the “Save” button. A “watch” icon will
appear. Shortly thereafter, a popup box should ap-
pear with a message that the save was successful
and asking if you want to “unmount” the ash drive
device. Press on “Yes” Button. If the “watch” icon re-
mains after a minute or so, then the MicroVission is
unable to close the backup le it has written to the
thumb drive. Power down the MicroVission and try
the procedure with a different thumb drive.
Replace Original SD card with New SD card
Now that the database le has been saved to the thumb
drive, you can replace the “original” SD card with a new
SD card.
1. Power down the MicroVission.
2. Remove the thumb drive and take out the “original”
SD card and install the new one.
3. Label both the old and new card to identify the com-
pressor it is for.
