WIZ107SR User's Manual

How to Start

As you can see in the schematic and at the EVB the module provide a 12 pin connection header (2.54mm = 100mil) with 3.3V TTL level IOs (5V tollerant) or +/-10V RS-232 level serial interface. Therefor the module need a stable 3.3V power suply to start operation.
As the W7100A chip provide Hardwired TCP/IP there is no operation system inside this Serial-to-Ethernet Gateway. The firmware is a 'simple' status machine and within a few ms the module operates normally with full performance.
To start the module need a configuration. There are 3 ways for that:

  1. by our Config Tool for Windows PCs over Ethernet / Internet
  2. by serial command - after entering software triggered “command mode” using the UART I/F
  3. by hardware signal triggered config mode (also use the UART I/F)

Below the 3 configuration sections we will also show you some application setup examples (Server, Client, mixed mode) - the “How to Use” section.

Configuration by Network

Please install our Config Tool on your Windows PC. It's open source so you can customize and check the insides. Within this config tool you find also the Network setup part as the first flag (part 10, 11 & 12):


The start position of our WIZ107SR / WIZ108SR config tool, after “Search”.

You always start with “Search”.
The Search function (pop-up window) is used to find all devices existing in the same LAN or in WAN. By using UDP broadcast, all connected devices in the same subnet will be found. If the TCP unicast method is checked, the specified IP address must be given. The founded device will be listed in the “Serial to Ethernet” tree with it's MAC address. The complete modules current setup is transfered and can now be changed.
Please, note the identification code must be input if the device has been configured with an identification code.

Search by UDP broadcast or IP address unicast - and identification code protection as option.

(2) Setting

This function is to complete the configuration change.
If (after search) you select the MAC Address from the “Serial to Ethernet” tree, the current configuration value of the module will be displayed. Change the configuration and click “Setting” button to complete the configuration. The module will re-initialize with the changed configuration. Changed value are permanently stored in the EEPROM of the module. Thus, the value is not removed even though power is disconnected.

(3) new FW Upload

From time to time we offer a new firmware (FW) for function and bug-fix updates. You can easy update the FW “over the air”, means by Network. More about that function further down.

(4) Reset

You can reset and restart the selected module if you select the MAC Address from the tree and click “Reset” button.

(5) Factory default settings

All configuration is set back to the original Factory default values if you select the MAC Address from the tree and click “Factory” button.

(6) Ping

It will Pop-up a Simple Ping application program, you can test the ping operation.

(7) Firewall

Popup the Windows Firewall setup program.

(8) EXIT

Close the configuration Tool Program.

(9) "Serial to Ethernet" search result list

If you click “Search” button, all modules' MAC address on a same subnet will be displayed in this area. You can see the basic information such as Model name, Firmware version, connection status …

(10) Network Seting

Select IP setting mode, you can select a Static setup or dynamic IP-address by DHCP.
(PPPoE mode is not supported in the WIZ107SR)
- Using a static IP Address:
This is an option for setting WIZ107SR module’s IP with static IP address. Firstly, select the Modules' MAC address which you wanted to set as static IP in the board list. Then “Device IP, Subnet, Gateway box” will be enabled. Input a static IP address and click “setting” button. Then the Module is restarting with that IP address.
- DHCP: Set this option to use DHCP mode. Firstly, check ‘DHCP’ and click ‘Setting’ button. If IP address is successfully acquired from DHCP server, the MAC address will be displayed again on the configuration window. As it takes some time to acquire IP address from DHCP server you might need to try “Search” a few times. When a module on the board list is displayed again and selected, the IP address, Subnet mask and Gateway are displayed. If the module could not acquire a new network information from a DHCP server, the IP address, Gateway Address and Subnet mask will be initialized to 0.0.0.0. You might try again or try a static IP setup.

(11) Network Operation Mode

Client / server / mixed : This is to select the communication method based on TCP. TCP is the protocol to establish the connection before data communication, but UDP just processes the data communication without connection establishment. The Network mode of WIZ107SR can be divided into TCP Server, TCP Client and Mixed mode according to the connection establishing method. At the TCP server mode, WIZ107SR operates as server on the process of connection, and waits for the connection trial from the client. WIZ107SR operates as client at the TCP Client mode on the process of connection, and tries to connect to the server’s IP and Port. Mixed modes supports both of Server and Client. The communication process of each mode is as below.

<TCP server mode Communication>

At the TCP Server mode, WIZ107SR waits for the connection requests.
TCP Server mode can be useful when the monitoring center tries to connect to the device (where WIZ107SR is installed) in order to check the status or provide the commands. In normal time WIZ107SR is on the waiting status, and if there is any connection request (SYN) from the monitoring center, the connection is established (ESTABLISH), and data communication is processed (Data Transaction). Finally connection is closed (FIN).
In order to operate this mode, Local IP, Subnet, Gateway Address and Local Port Number should be configured first.

The Data transmission proceeds as follows,

1. The host connects to the WIZ107SR which is configured as TCP Server mode.

2. As the connection is established, data can be transmitted in both directions – from the host to the WIZ107SR, and from the WIZ107SR to the host.

<TCP client mode Communication>

If WIZ107SR is set as TCP Client, it tries to establish connection to the server. To operate this mode, Local IP, Subnet, Gateway Address, Server IP, and Server port number should be set. If server IP had domain name, use DNS function. In TCP Client mode, WIZ107SR can actively establish a TCP connection to a host computer when power is supplied.

The Data transmission proceeds as follows:

1. As power is supplied, WIZ107SR board operating as TCP client mode actively establishes a connection to the server.

2. If the connection is complete, data can be transmitted in both directions – from the host to the WIZ107SR and from WIZ107SR to the host.

<Mixed mode Communication>

In this mode, WIZ107SR normally operates as TCP Server and waits for the connection request from the peer. However, if WIZ107SR receives data from the serial device before connection is established, it changes to the client mode and sends the data to the server IP. Therefore, at the mixed mode, the server mode is operated prior to the client mode.
As like TCP Server mode, the Mixed mode is useful for the case that the monitoring center tries to connect to the serial device (in which WIZ107SR is used) to check device status. In addition to this, if any emergency occurs in the serial device, the module will change to Client mode to establish the connection to the server and deliver the emergency status of the device.

<UDP mode Communication>

UDP is not a connection oriented protocol. But the communication port should also be defined well. If the UDP mode is selected, the data from serial interface can be defined where to delivery via the “Sever IP Address” and “Port”, and the WIZ107SR can also be defined where to receive Ethernet data from via the “Remote Peer IP Address” definition. If the data destination and source are the same, the two IP address will also be the same. Please note the destination and source are using the same port.
