5.6  Watchdog Timer Mode (JWT1) 

Jumper group JWT

1 determines the behavior of Pluto’s watchdog timer, as indicated in the table below. In the 

case of a Reset (2-3 shorted), a watchdog timer time-out condition produces the same effect as pressing the 
front-panel reset button (see interface connector PWR1). 

 

Setting 

Mode 

 

Short 1-2 

Timeout triggers non-maskable interrupt (NMI) 

 

Short 2-3 

Timeout triggers system Reset (Default) 

 

Open
