Chapter 1 Hardware configuration 3
The card has power on self test (POST) LEDs for quick and simple
fault analysis. A backup of CMOS data is stored in the EEPROM,
which protects data even after the battery has failed. The industri-
al-grade construction of this card allows it to withstand continuous
operation in harsh environments at temperatures up to 140
°
F
(60
°
C). Also included is a 12-level watchdog timer, which resets the
CPU or generates an interrupt if a program cannot be executed
normally. This enables reliable operation in stand-alone or unat-
tended environments.
