Main Board LOW_PWR_SUSPEND Event X X 03.10.0012
Power Management System places system in low power
mode when 12VDC Lead Acid Battery State of Charge
(SoC) drops below specified threshold for location and
time of year.
While in low power mode, system will:
• check SoC threshold every hour
• sends STAR time syncs every day
• wakeup once every 72 hours to provide 6 hours of
normal operation
Main Board MAC0=00:19:2B On Reset X X
First three octets of MAC address (Organizationally
Unique Identifier) Only present for Ethernet boards.
Main Board MAC1=00:13:9F On Reset X X
Last three octets of MAC address (Network Interface
Controller specific) Only present for Ethernet boards.
Main Board MBFW=03.00.0002 On Reset X X
Motherboard Firmware Version identifier. Format is
VV.RR.bbbb where VV is firmware Version number, RR is
firmware revision number, and bbbb is build number.
Main Board MTU_FOTA_END= Event X X MTU Firmware-Over-The-Air (FOTA) Ended.
Main Board NoData! X X
This message occurs when the DCU connects with an
empty data buffer. This normally indicates that the
communication with the NCC was dropped after
receiving the clear command but before any records
have been transferred.
Main Board PCount=35272 On Change X
Number of DCU records purged to remove outdated
records or make room for new/higher priority records
The DCU will purges electric records first. Gas/water
(STAR) records will then be purged once memory is full.
Main Board REBOOT_BATT_CHRG Event
X
03.10.0012
Power Management System transitions DCU from low
power mode to normal operation because adequate
Solar or AC power is available to operate system while
charging 12VDC Lead Acid battery even while battery
below SoC threshold.
Main Board REBOOT_BATT_OK Event
X
03.10.0012
Power Management System transitions DCU from low
power mode to normal operation because 12VDC Lead
Acid battery SoC above SoC threshold.
