2.5 Watchdog Timer Setting
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-2571 supplies a jumper for users to active the watchdog timer
or not. Inside the WF-2571 users can use the JP1 to activate the WDT
built in the module, as the Figure 2-6. Note that the default setting is active.

2.6 FW / OP Dip-switch
On the top of the WF-2571 series module, there is a dip-switch used
for firmware operation or firmware update modes selection of the module.
2.6.1 Firmware Update Mode
Please set the dip-switch to the “FW” position as Figure 2-7, and then
the WF-2571 will work in the “Firmware Update Mode” after reset the
power. In this mode, users can update the firmware of the WF-2571 via
USB interface and it will become a “USB Mass Storage Device” and
shows a folder automatically.
