Figure 3-3 UDP mode diagram
For UDP mode in Figure 3-3, W7500S2E-R1 module is required to have the remote IP address
and port number to create an UDP communication. UDP mode communicate is not based on
“connection”. Therefore, it does not guarantee the target device could receive the data correctly
or not. Thus, it requires an upper layer communication protocol to communicate for ensuring the
data accuracy. However, since UDP mode is a simple communication protocol, it could provide a
better communication speed due to less workload on data accuracy. In fact, UDP are not likely to
get data error in network environment under normal workload. In this operating mode, both
devices are equal, and they do not differentiate into server or client.

4 IP address
Before using the module, we need to know some parameters like IP address. This module
support “Static” and “DHCP” IP collection method. For “Static” mode, user could manually
change the IP address, subnet mask & gateway parameters. The emphasis here is that the IP
address of the module cannot be the same as the IP address of other devices in the same LAN. i.e.
the module will activate DHCP protocol to collect IP address, subnet mask and gateway
information from the DHCP server.
4.1 Module IP address factory default settings
WIZS2E Serial to Ethernet module’s factory default IP address: 192.168.1.88.
4.2 Method to get the IP address of the module
No matter forgotten the IP address of the module or the module is working on DHCP mode, the
current IP address of the module could be searched using the WIZS2E ConfigTool. The
following steps are the method to use WIZS2E ConfigTool to search the IP address for WIZS2E
module:
1. Connect the host computer and the module with LAN cable and power up the module.
2. Run the WIZS2E ConfigTool and it shows as the following 4-1 figure.
Figure 4-1 WIZS2E ConfigTool interface
3. Press button, it shows the IP address information as the following figure 4-2.

4.3 Module and host computer network detection
Before starting to communicate between the WIZS2E module and the host computer, please
ensure the host computer and the module are in the same network segment.
The factory default setting for IP address and Subnet mask in WIZS2E module are 192.168.1.88
and 255.255.255.0 respectively. User could follow the flow diagram 4-3 to understand the
communication procedure between the module and the host computer. If they are in the same
network segment, it could communicate with the module. Otherwise, the host computer needs to
change its IP address to communicate with the module.

The following procedure is based on Windows® 7 Operation System.
Press “Start” → “Control Panel” → “Network Sharing Centre” → “Changing adaptor setting” →
“Local connection” → Right Click “Properties” → Double Click “Internet protocol version 4
(TCP/IPv4)”. After all these procedures, you could get into the result as the following figure
shows. Please choose “Using the following IP addresses” for inputting the IP address as
192.168.1.99, the subnet mask is 255.255.255.0 and default gateway into 192.168.1.1. The DNS
section could ignore. Finally, please click “Enter” for saving these settings and starts to
communicate with WIZS2E module.

5 WIZS2E ConfigTool
WIZS2E ConfigTool is a Windows® configuration tool compatibles to W5500S2E and
W7500S2E series modules. WIZS2E ConfigTool can be used to search, enquiry and configure
W5500S2E and W7500S2E device features and information.
5.1 Collect module’s setting information
Click the toolbar’s button, WIZS2E ConfigTool will search all WIZS2E module that
has connected in the same network segment (Direct connect or under the same router). The
figure 5-1 shows the result as mentioned. The search section shows all the modules in MAC
address format as the parent node for the list of information of WIZS2E module. By pressing the
“ ” button, it shows the detail information about this module. After pressing the MAC address
of that specific module, it will list out all the IP address, serial interface settings and other
parameters of this module. This information presents on the Basic settings and Advance Option
tab that were next to the search section.
Note: Prior configuration, it is recommended that you disable other unrelated network adapters in
your host computer (including virtual network adapters, if you use the wired network adapter
configuration module to turn off the wireless network card) and ensure that all device IP
addresses in the LAN are not conflicting.

5.2 Modify the device settings
After searching the module, user could directly go to “Basic Settings” and “Advance Options” to
configure the module. Please press button to save your configuration.
5.3 Useful features
5.3.1 Switching Ethernet Interface
To solve the issue that it is impossible to determine whether the wired or wireless
network interface is currently used when configuring the module, the tool has added
a function of switching the network interface. User can set the network card to
search and configure according to the actual situation, click “Update IP list!” The list of network
interfaces can be updated.
5.3.2 Right mouse button
Right-click on the device list on the left, and the function list will appear as shown in the figure
