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.
(Firmware below R9.4a only): 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 44
).
IMPORTANT:
You must retain the correct file extension (.cdf or .ssd).
4.
Remove the 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.
(Firmware below R9.4a only): 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.
Using Notepad or a similar editor, 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 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, delete the
.txt
extension from the command file. Then right-click the
command file filename and choose Properties. In the General tab, click to put a checkmark in the
Read-only box. 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 firmware file to the
sdcard0
directory. This directory must contain only one firmware
file.
c.
In the
sdcard0
directory on the card, create a new directory and name it:
strategy
Copy the renamed strategy file (.cdf or .ssd) to the
sdcard0/strategy
directory.
The card is now ready to be used as a commissioning card to replace the controller.
Replacing the Failed Controller.
Before you start, make sure that the replacement controller:
•
Has
exactly the same part number
as the old controller (for example, a SNAP-PAC-S1-W must be replaced
by a SNAP-PAC-S1-W)
