9) Search window

If you click “Search” button, all the MAC address on a same subnet, will be displayed this

area. You can see the basic information such as Model name, Firmware version Etc.

10) Network Setting Method

Select IP setting mode, you can select one of Static, DHCP.

(PPPoE mode is not suppor t ed in the WI Z107SR)

- Using the follow IP Address (Static)

This is option for setting WIZ107SR module’s IP with static IP address. Firstly, select

MAC address which you wanted to set as static IP in the board list. Then “Device IP,

Subnet, Gateway box” will be enabled. Input Static IP address and click “setting”

button. Then set the IP address as you want.

- DHCP

Set this option to use DHCP mode. Firstly, check ‘DHCP’ and click ‘Setting’ button. If IP

WIZ107SR User Manual (WIZnet Co., Ltd.) 9

address is successfully acquired from DHCP server, the MAC address will be displayed on

the configuration window. (It takes some time to acq u ire I P address from DHCP server)

When a module on the board list is selected, IP address, Subnet mask and Gateway are

displayed. If module could not acquire network information from DHCP server, IP

address, Gateway Address and Subnet mask will be initialized to 0.0.0.0.

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.

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, Lo cal 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

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.

WIZ107SR User Manual (WIZnet Co., Ltd.) 10

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

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 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.

12) DDNS Setting

DDNS function is not supported in the WIZ107SR.

WIZ107SR User Manual (WIZnet Co., Ltd.) 11

2.1.2 Serial Configuration

Figure 7. WIZ107SR Configuration Tool (Serial Configuration Page)

1) Enable debug message output

If this mode is checked, you can monitor the status of module and socket message like

listen OK, connect fail etc. through serial terminal. If debug mode is on, debug message

can cause abnormal operation of the serial device. Therefore, just use this mode only for

debug mode.

2) COM port Setting

The parameters of COM port of WIZ107SR are listed well in this page. Us ers can set the COM

port of WIZ107SR by selecting the value of each parameter in the drop down list.

☞ By clicking the “Setting” button, changed value can be applied.

3) Serial data packing condition settings

You can designate how the serial data can be packed to send to the Ethernet.

In default mode, WIZ107SR checks the serial buffer and sends any received data to Ethernet

without any standard. Therefore, the data can be regarded as error data due to

WIZ107SR User Manual (WIZnet Co., Ltd.) 12

inconsistent data length. In order to solve this problem, the data from serial can be packed

according to the specifie d condition before sending to Ethernet. The condition is as below.

Time: If there is not any new data during designated time, all data in the serial buffer is

converted to Ethernet packet. If new data is received, the time is re-calculated and

the received data is saved in the serial buffer. Time condition can be utilized when

the serial data size is variable and has no ending char acter, but needs to be delivered

in frame unit. (If the value is ‘0’, option is not used)

Size: When data is collected as much as the defined size in the serial buffer, it is

transmitted to Ethernet (If the value is ‘0’, option is not used)

Character: The data is collected in the serial buffer until specified character is received,

and transmitted to Ethernet. The character can be specified in Hex formation.

(The value is ‘0’, this option is not used)

One of three conditions is sati sfied, the data is transmitted to the Ethernet.

Ex) Delimiter : Size=10, Char=0x0D

Serial data : 0123456789abc

Ethernet data : 0123456789

☞ “abc” data remains in the serial buffer of module.

4) Serial command mode switch code

This function is for module configuration not through network with Configuration tool but

through serial communication. At the default status, the serial command mode is disabled.

When you want to set via serial communication, check “enable”.

WIZ107SR User Manual (WIZnet Co., Ltd.) 13

2.1.3 Option Configuration

Figure 8. WIZ107SR Conf iguratio n Tool (Option Configuration Page)

1) T imer interval

- Inactivity Timer : The connection holding pe riod when no data transmission.

- Reconnection Interval : The connection retry interval (client mode only)

After the connection is established, if there is not data transmission within the time

defined in Inactivity time, the connection is closed automatically. The default value is ‘0’.

If ‘0’ is set, this function is not activated. In this default setting, the connection is

maintained even though there is no data transmission. In order to close the connection, the

‘Close’ command should be given.

This function can be used for more than two or more systems to connect to a WIZ107SR

module. If one system holds the connection to the WIZ107SR, other systems cannot connect

to the module. If there is no data transmission during the time defined in Inactivity time,

the connection will be closed for other system to be connected.

WIZ107SR User Manual (WIZnet Co., Ltd.) 14

Inactivity Time also can be useful for the case when the server system is unexpectedly shut

down. In this status, if there is not any data communication during the time defined in the

Inactivity time, WIZ107SR will close the connection and enter into waiting status.

2) Search identification code

For the security issues, WIZ107SR can have it s own password for searching. The password is

stored in the EEPROM of WIZ107SR, and it can be modified via this configuration tool. The

password can be any alphabet or number. Its length can be variable and its maximum length

is 8 bytes. The password is case sensitive.

3) Connection password

This function is available only when WIZ107SR works in server mode. If this function is

enabled, the remote client should send the password to WIZ107SR before data transmission.

Please, note the password is case sensitive.

4) Network protocol settings

There are two kinds of data transmission protocol: one is raw data transmission, and the

other is using Telnet (RFC2217).

But in current version, only the raw data transmission is supported.

If the ‘Keep alive’ function is enabled, WIZ107SR will send keep alive packet in every user

set minutes if no reply received after the user set period.

WIZ107SR User Manual (WIZnet Co., Ltd.) 15

Table 5. Serial command response list

3.3 Serial Command Executing Example

Figure 13. shows an example with several commands executed. At first, WIZ107SR should be

set into serial configuration mode (both hardware trigger and software trigger can be used).

For hardware trigger, the trigger should be turned on and reset the WIZ107SR, and the

software trigger code should be sent to change WIZ107SR into serial configuration mode.

In this example, the serial echo message is on and the software trigger is used to enter the

serial configuration mode. And then, the user inputs command ‘MC’ with ‘Enter’ key pressed

to read the MAC address of the WIZ107SR. You can find that the WIZ107SR responses with

‘MC00:08:DC:01:02:03’. In the same way, we can read the IP address of WIZ107SR. This

example also shows how to modify the parameters of WIZ107SR. After reading IP address, the

user inputs ‘LI192.168.11.20’ with ‘Enter’ key pressed in hyper terminal. You can find that the

IP address is set to ‘192.168.11.20’ a fter ‘LI’ command executed correctly.

Attentions:

1) The ‘SV’ command must be executed if you want to save your new parameters.

2) The ‘RT’command must be executed if you want to execute your new parameters

3) The ‘EX’ command must be executed if you want to leave the serial configuration

mode.

WIZ107SR User Manual (WIZnet Co., Ltd.) 25

4) Example:

Refer to 1)~3), usually if you want to change the operation mode from Server to

Client, you should input something like this:

OP0 --->SV--->RT

Please, note that the data connection will be closed once the WIZ107SR goes into serial

configuration mode.

Figure 13. Serial command executing example

Attentions:

1) The ‘SV’ command must be executed with some delay (about 50ms) for WIZ107SR’s

stable operation.

2) Recommend to use the serial commands with some delay (about 10ms) for stable

operation

3) After execute serial command, We recommend to check the parameters using

response serial command like “LI\r\n”.

Output> LI192.168.11. 2

4.4 HW_TRIG PIN

The way of detection connect status is monitoring the HW_TRIG Pin. When the connection is

established, HW_TRIG pin goes Low. And, it will go HIGH when connection is closed. Actually,

this pin works both direction, like Input and Output.

In the initial time, this pin is INPUT for Hardware Trigger (for serial command mode).

After that, this pin is OUTP UT for connection status.
