IMPORTANT:
You must retain the correct file extension (.cdf or .ssd).
6.
Create a directory on the card in the root and name it:
strategy
Remember, if you are looking at the card
in the controller
, you create the
strategy
directory in the
sdcard0
directory. If you are looking at the card
in a card reader
, create the
strategy
directory at
the top level. The controller’s file system treats the card as a directory named sdcard0.
7.
Copy the renamed strategy file to the
sdcard0/strategy
directory on the microSD card.
Here’s an example of a strategy file in the strategy directory, looking at the card in the controller:
8.
If you plan to save the strategy to flash memory, delete the following files and directories if they are on
the card:
NOTE: If the controller has firmware 9.0a or newer and a loader version older than 6.0a, you cannot save the
strategy from the card to flash memory.
9.
To update, run, or test the strategy, turn off the controller, put the card in, and turn the controller back on.
The controller loads the strategy from the card (verifying the signature if it is an .ssd file), switches to the
new strategy if you’re using background downloading, and runs the new strategy if you set it to autorun.
If it’s not set to autorun, you can start the strategy manually using PAC Control or PAC Terminal.
The STAT LED blinks steadily while the strategy is loading and then blinks two sets of three blinks—green
to indicate success, or red to indicate failure. When the STAT LED no longer blinks steadily, but blinks only
once every five seconds, it has finished.
10.
If you want to save the strategy to flash memory, carefully insert a straightened paperclip or stiff wire into
the small hole on the controller labeled R
ESET
.
Press and hold the Reset button just until the STAT LED
turns solid green, and then immediately release the button.
The strategy is saved to flash memory. (If IP address, configuration, or firmware files are on the card, they
are also saved to flash memory.) Then the controller restarts.
11.
Wait until the STAT LED blinks only once every five seconds, and then remove the card.
