Introduction
The WF-2572 is an industrial Ethernet to Wi-Fi Bridge. The device only needs to connect
the Ethernet cable with WF-2572 that can create an IEEE 802.11 a/b/g wireless personal
network. The interface between Ethernet and Wi-Fi use transparent transmission so that it can
convert Wi-Fi to wire internet without complex settings. The WF-2572 also supports dual
bands (2.4/5 GHz). The 2.4 GHz is more crowded than 5 GHz. Therefore, the devices on 2.4
GHz suffer much more interference than the ones on 5 GHz. The WF-2572 has less interference
on 5 GHz.

2.4 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-2572 supplies a jumper for users to active the watchdog timer or not. Inside the
WF-2572 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.
Figure 2-4. Watchdog Setting
2.5 FW / OP Dip-switch
On the top of the WF-2572 series module, there is a dip-switch used for firmware
operation or firmware update modes selection of the module.
2.5.1 Firmware update mode
As shown in Figure 2-5, it need to set the dip-switch to the “FW” position after that the
WF-2572 will work in the “Firmware Update Mode” after reset the power. In this mode, users
WF-2572, Ethernet to Wi-Fi Bridge (V1.00, 2018/09/30) 10
can update the firmware of the WF-2572 via USB interface and it will become a “USB Mass
Storage Device” and shows a folder automatically.
Figure 2-5. FW update position of Dip-Switch
Figure 2-6. USB Mass Storage Device
Users just need to execute “Firmware_Update_Tool.exe” and follow the below steps
to complete the firmware updating process.
Step1. Choose “USB” interface and “USB Disk”.
Step2. Click “Browser” button to choose firmware file. (e.g. WF2572_V100.fw)
