SNAP PAC FIRMWARE README

To get the latest firmware:

  1. Go to Support > Downloads. Filter on Firmware and type SNAP PAC (or SoftPAC or G4EB2) in the search field to narrow results. 
  2. Click the file for your part number in the list, and then download and save it to your computer.
    Alternatively, if you have multiple part numbers, you may find it easier to obtain the Single Download, which includes all of them. 
  3. Before installing firmware, review “Selecting the Correct Version of PAC Manager to Install Firmware” in the README.
    Reminder: The firmware no longer allows you to download PAC Control strategies with controller redundancy. To continue running these strategies, you must run firmware version R10.4e or lower.
  4. Before installing firmware, carefully read the first few pages of the README document to verify which firmware versions are compatible with your controller, based on its ship date.
