3.f.1. Power Loss Recovery Watchdog
When the unit is in collection mode (collecting data) it is crucial that data collection continue even when power failures
occur. The battery can sustain the unit for weeks in the event of loss of charging, however, when the unit battery is
almost depleted (5.4v) the system will close the data file in order to go into a super low power sleep mode to eliminate
“dirty” shutdown of the unit and data corruption. During the sleep mode a watchdog is monitoring the battery voltage and
if the battery charging resumes will power the unit back on and start the data collection mode to ensure the most uptime
in data collection.
3.g. Memory
The Phoenix II comes standard with 1MB (original Phoenix is 68k) of on-board memory for storage of collected study
data. The Phoenix II can store up to 99 files total in SRAM memory on-board the MDK circuit board. The optional
addition of the extra memory via the add-on of a memory circuit board (accompanied with the piezo sensor circuit board)
allows the utilization of SD/MMC flash memory cards to be used to store anywhere from 16MB – 4GB of extra file
storage. The SD/MMC option also increases the number of files the counter can store up to 65,532 files total. This
extra memory can be useful in collecting PVR, WIM, SENSOR and small interval BINNED data to allow for longer
collection times before filling the memory space. (Please refer to Appendix B for details regarding memory space)
SD/MMC card options can be configured for to be removable or non-removable access. In the case of the removable
option, a SD/MMC card slot is installed on the faceplate of the Phoenix II unit for easy access to remove and replace
memory cards by the user in the field. SD/MMC cards are readily available in most electronic stores and camera supply
stores.
