strategy follows the status of the existing strategy: if the existing strategy was running when
the card was inserted, the new strategy will run; otherwise, it will not.)
If you use background downloading, the controller will switch to the new strategy when the
card is inserted.
3.
Choose one of the following:
a.
If you’re using Secure Strategy Distribution, follow steps in form #1762, the
PAC Terminal
SSD Technical Note
, to create a download file with the file extension .ssd.
b.
Otherwise, compile the strategy as a Control Engine Download file (.cdf ) by right-clicking
the name of the control engine in the Strategy Tree and choosing Compile Control Engine
Download File from the pop-up menu.
The file is created in the same folder as the strategy, with a .cdf extension and a filename
consisting of the strategy’s name and the control engine’s name (for example,
MyStrategy.MyEngine.cdf ).
4.
Rename the .cdf or .ssd strategy file to fit the 8 dot 3 filename format for the microSD card (see
“Card Type and Format” on page 42
).
IMPORTANT
: You must retain the correct file extension (.cdf or .ssd).
5.
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. You can’t see the
sdcard0
directory, but it is still there.
6.
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:
7.
Choose how you want to use the card with the controller:
a.
Turn off the controller, put the card in, and turn the controller back on.
The
controller will load the strategy from the card (verifying the signature if it is an .ssd file),
burn the strategy to flash if you told it to do so, switch to the new strategy if you’re using
Strategy file
