Real Time Clock (RTC)
The CPU includes a low drift RTC. The date and time are retained using an on-board
rechargeable lithium battery.
The CPU date and time can be set using the ACE3600 STS. The CPU can also be
synchronized with other RTUs in the system, using the system clock. For more information,
see the Setting/Getting a Site's Date and Time section of the ACE3600 STS User Guide.
Backup Battery for RTC
The CPU module includes a rechargeable lithium battery that provides backup power and data
retention for the RTC.
The lithium battery is located on the CPU board and cannot be replaced.
Typically, the battery will retain the RTC for 40 continuous days without power and no Lead-
Acid backup battery.

ACE IP Gateway Firmware and Operation Modes

The ACE IP Gateway firmware is a real-time multitasking operating system, based on the
Wind River VxWorks OS. The GW shipped from the factory with the most recent firmware
version, and it can be updated/replaced using a remote or local connection. Downloading
firmware updates is performed using the STS. (See Downloading to a Site in the ACE3600
STS manual.) If the new firmware download stops or fails, the GW will restart with the
existing firmware.
