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.

FW / OP Dip-switch

On the top of the WF-2000 series module, there is a dip-switch used
for firmware operation or firmware update of the module. The following
steps show how to use this dip-switch.

2.6.1 Firmware Update Mode

Please set the dip-switch to the "FW" position as Figure 2-7, and then
the WF-2000 series will work in the "Firmware Update Mode" after reset
the power of the module. In this mode, users can update the firmware of
the WF-2000 module from computer's RS-232 port via CA-0910 cable
