How to upgrade firmware for Rx3i CPU

Hello!

I would like to download and install the latest firmware versions for our PAC Systems CPUs and other modules (CMX128, RMX128). We have the following products:

- I695CRU320

- I695CPE305

- I695CMX128

- I695RMX128

Does anyone have a procedure on how to perform these firmware upgrades? Also, where can I get the latest versions?

Any help is highly appreciated.

  • Hi Marcelo, you can sign up for downloads of documentation and files at www.emerson.com/iac-support.
  • Hey Marcelo, when you open the firmware file after you download it, it should contain a file named FirmwareupgradeInstructionsRx3iCPEs. That will have the instructions you are looking for. I've done the CPE305s, not the other 3 you have listed, but those have went pretty smoothly. Seems like the end of the instructions say the light should keep flashing, but it doesn't, it just flashes a few times and then turns off (or something like that).
