ACCESI I/O P104-WDG-E 4-pin right-angle 2x2 header (9-12) PC/104 Plus Watchdog Timer Status Monitor Simple Type: Data Acquisition
Economy version which includes the full programmable watchdog timer with open collector outputs that can reset the computer. This requires your application program to have embedded watchdog software code that communicates a prompt to the timer. If this prompt is missed, a hard computer reset is initiated after the user programmed watchdog timer period has been reached. This is valuable where the lock up of the application is due to being in a software loop where some hardware watchdogs cannot detect.
