When a new version of Access It! is released, it ships with the appropriate SCP firmware to ensure proper compatibility. The firmware being distributed with the software is the minimum level firmware required to support the feature set within the application. The system will check to verify that each SCP is running the proper firmware and if it is not, it will automatically be downloaded to the SCP.
For information regarding the un-installation of SCP hardware, please refer to the SCP Automatically Uninstalled KB article.
