contact Product Support.
Follow these steps to replace the failed controller:
7.
Turn off the controller that failed. Put the new controller in its place but DO NOT apply power. Attach
network cables.
8.
Insert the prepared microSD/SDHC card and turn on power to the controller.
9.
Without waiting, 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 IP address is assigned to the controller, and firmware, configuration data, and strategy are loaded into
RAM, in that order.
–
In firmware R9.2c and newer, IP address, firmware, configuration, and strategy are stored to flash and
the controller reboots running the new firmware. The STAT LED blinks steadily during this process
and then blinks two sets of three blinks—green to indicate success, or red to indicate failure.
–
In firmware R9.0–R9.2b, IP address, firmware and configuration are stored to flash and the controller
reboots running the new firmware and loads the new strategy. To store the strategy to flash, use the
Reset button again in exactly the same way.
When finished, a folder named
backup
is placed in the root directory of the card. The controller
restarts.
10.
Wait until the STAT LED blinks only once every five seconds, and then remove the card.
Updating Firmware
The card can also be used to update firmware if the controller is not on the network, or if PAC Manager isn’t
available.
CAUTION:
Before updating firmware, make sure you know what is on the card! Any IP address, configuration data,
and strategy on the card will be saved to flash memory along with the 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.
(Firmware below R9.4a only): Rename the firmware file to fit the 8 dot 3 filename format (see
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:
