– If you’re using Secure Strategy Distribution (SSD), follow steps in form #1762,
the
PAC Terminal SSD Technical Note , to create a download file with the file
extension .ssd.
– 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 ).
d.
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 50 ).
IMPORTANT: You must retain the correct file extension (.cdf or .ssd).
4.
Remove the microSD card from the controller and put it in a card reader attached to
the PC. Prepare the firmware file:
a.
Locate the firmware file you want to upgrade to.
b.
Rename the file to fit the 8 dot 3 filename format.
For this file, do not keep the same file extension. Recommended naming scheme:
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
5.
Create the firmware command file:
a.
Create a text file named:
command
In the
command
file, type the following command (CASE SENSITIVE):
Krn <file>
<file> is the firmware path and filename as the microSD card sees it, so do not
include the sdcard0 directory in the path. If you’re using Secure Strategy
Distribution, <file> must include a valid signature. Here is a sample command file:
b. In Windows Explorer, right-click the command file filename and choose Properties.
In the General tab, click to put a checkmark in the Read-only box. Then click OK.
6.
Copy files to the card:
a.
Copy the command file to the
sdcard0
directory in the controller’s file system.
b.
Copy the renamed firmware file to the
sdcard0
directory. This directory must
contain only one firmware file.
