MAINTAINING THE CONTROLLER

1.
Obtain the correct firmware file from our website, www.opto22.com. If you are using Secure
Strategy Distribution (SSD), the firmware must have the correct signature.
2.
Rename the firmware file to fit the 8 dot 3 filename format (see
“Card Type and Format” on
page 42
).
The original file extension does not have to be retained. To make sure the file is clearly
identified, we recommend a name such as the following:
PPP-TMM.mmb
where:
Example of a recommended firmware filename:
R2-R8.4a
3.
Copy the renamed firmware files to the card.
You can write to the card in one of two ways: either use your PC to FTP files to the card in the
controller, or use a card reader with your PC and simply copy files with Windows Explorer.
4.
In the root directory of the card, create a command file named
command
(If you are looking at
the card in a card reader, you are in the root directory. If you are looking at the card in the
controller, the root directory is
sdcard0
)
5.
In the
command
file, include the following command. All commands are CASE SENSITIVE.
The following sample command file updates firmware on the controller.
6.
To update firmware, insert the card in the controller’s card slot.
The controller reads the command file, updates firmware, and saves controller firmware to flash
memory. When finished, it places a file named
response
in the root directory of the card; this
file indicates the success or failure of each command. Then the controller restarts.
7.
After the controller restarts, remove the card.

firmware
Krn <file>
<file> is the firmware path and filename as the microSD
card sees it, so do not include
sdcard0
directory in the
path. The firmware file can be compressed in gzip format
or uncompressed.* If you’re using Secure Strategy Distri-
bution, <file> must include a valid signature.
NOTE: Controller firmware will be installed only if it differs
from the current firmware.
* To gzip a file on Windows, use the utility at
http://gnuwin32.sourceforge.net/packages/gzip.htm
.
SNAP PAC cannot decompress files that were compressed with WinZip
