Introduction
1.4.3 Hardware Monitor Alarm (JOBS1) and Watchdog Timer Output
(JWDT1)
AIIS-1240 contains a watchdog timer that will reset the CPU in the event the CPU
stops processing. This feature means AIIS-1240 will recover from a software failure
or an EMI problem. The JWDT1 jumper settings control the outcome of what the
computer will do in the event the watchdog timer is tripped.
AIIS-1240 also provides jumper: JOBS1 to enable or disable hardware monitor func-
tion.
