firmware. If you want only the firmware saved, delete configuration and strategy files from the
card.
CAUTION:
Updating firmware deletes your PAC Control strategy (even if stored to flash memory)
and your persistent variables. Make sure you have
archived
your strategy before loading new
firmware.
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 50
).
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 an original firmware filename:
snap-pac-r2-R9.0a.bin
Example of the same firmware file, renamed:
R2-R9.0a
3.
Copy the renamed firmware file to a blank microSD card. If you don’t have a blank card,
delete the following directories and their contents if they appear on 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, go to the root directory. If you are looking at the
card in the controller, go to the directory named
sdcard0
).
