2.5 Jumper Settings
2.5.1 Watchdog Timer Settings
A watchdog timer (WDT) is a device that performs a specific
operation after a certain period of time if something goes wrong and the
system does not recover on its own. A watchdog timer can perform a
warm boot(restarting the system) after a certain number of milliseconds.
The WF-2000 series module supplies a jumper for users to active the
watchdog timer or not. If users want to use this WDT, can open the WF-
2000 cover and use the Jumper to activate the WDT built in the module,
as the Figure 2-13. Note that the default setting is active.
