The primary reason for saving a copy of your configuration file from the Paradigm Architectural Control Processor (P-ACP) is to simply have a backup in the unfortunate event your P-ACP has an issue which requires replacement or a loaner as part of the repair processor. Additionally if you have questions about your system, emailing your config file to ETC Technical Support will help them get you an answer more quickly.
To save the config file from a P-ACP you will need either a USB thumb drive, or a SD card (2GB or less). Both media types need to be formatted as FAT32.
