ⓚ Use UDP mode
At the UDP mode, the connection establishment is not defined. Just set the IP address and
port number of the peer and send the data.
ⓛ Use DNS : If DNS function is needed, check this option and input the domain name of DNS
server. DNS(Domain Name System) is the database system having information about IP address
and corresponding domain name. When connecting to domain name, you can use DNS function
of WIZ100SR. Input IP address of DNS server provided by ISP in DNS Server IP, and domain
name in the Server (Domain)
If server has dynamic IP address, but domain name, if you use DNS function, you do not need
to configure server IP address whenever it‟s changed.
ⓜ Direct IP Search
Direct IP Search can be used for searching WIZ100SR not installed in the same subnet.
If the Direct IP search is checked, the configuration tool use the TCP instead UDP broadcast to
search modules. Therefore, network information of the module such as IP address, subnet
mask and gateway is required for the search.
If you check Direct IP search, the field in which IP address is input, will be activated. In this
field, input IP address of the module, and click “Search” button.
☞ If module does not have valid network information, Direct IP search is not available.
Check if module is connected to the NAT or private network. If so, it is not possible to
connect to the module from outside.
Hardwired Internet Connectivity Wizard (WIZnet, Inc.)
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 WIZ100SR 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.
