Other
• An on-board real time clock maintains the date and time, taking into account
leap year and accounting for global time zones and daylight savings time
changes.
• The database for the system configuration and card holders are stored in FLASH
memory.
• The event log buffer is stored in battery-backed memory.
• Configuration data and event/status reports are communicated to the host via
on-board 10-BaseT/100Base-TX Ethernet port.
• Transactions are stored in 1 MB of battery-backed SRAM. The maximum
number of transactions stored while the host is offline is 50,000.
• Cards are stored in Flash memory and read into DRAM when the board is
powered up. The amount of storage available for cards and biometric records is
15 MB. The maximum number of cards depends on the card record database
configuration, but the number is approximately 300,000. This maximum is
dependent on how the card is configured with more space per card used with
longer card number, more clearance codes, and so on.
