Backup battery power management

When the main power drops below 9 VDC, the DRM switches to backup battery power and disables power to V4 (the SmartFlux System will power off). The DRM will continue to power V1, V2, and V3 outputs.

Data from sensors on the DAqM will be temporarily stored on the DRM until its memory gets full, after which the DRM will temporarily power on the SmartFlux System and transfer biomet files to it, where they are stored on the USB drive. Alternatively, biomet data files are transferred from the DRM to the SmartFlux System when main power is restored.

Each of the DAqM switched power outputs (SW1, SW2, and SW3) and controlled outputs (C1, C2, C3, and C4) can be configured to be disabled while the DRM is powered by the backup battery. This is useful in order to maximize the life of the backup battery (by disabling these outputs, the backup battery will be depleted more slowly).
