PC Settings
Double check that the WIZ750SR-100 and the PC, or laptop you are using to set up WIZ750SR-100 with are both on the same Ethernet network.
Example: PC Network Settings
* When the WIZ750SR-100's settings are factory default,
| Network Settings | PC or laptop (= Remote) | IP address | 192.168.11.3 | - |
|---|---|---|---|---|
| ::: | ::: | Gateway address | 192.168.11.1 | - |
| ::: | ::: | Subnet mask | 255.255.255.0 | - |
| ::: | ::: | Port number | 5000 | - |
-
User should to matching the network settings of 'WIZ750SR-100's remote host' and 'PC (or laptop)' for testing TCP client/mixed mode.
-
If the DHCP(automatic IP allocation) is used, both the WIZ750SR-100 and test PC must be set to be assigned the same IP from the same router.
Connecting Steps
The WIZ750SR-100-EVB is designed to use the DB9 connector to connect with the user’s serial device. Therefore, it is recommended to have all Ethernet and serial ports connected to the PC when testing. If the PC does not have a serial port, please purchase a RS-232 to USB converter separately.
Step 1: Plug in
Connect the WIZ750SR-100 module to evaluation board and also the cable as shown in the picture below.
-
Ethernet Cable
- Used to connect the evaluation board’s RJ-45 connector and the PC’s Ethernet network interface card (PC's RJ-45 connector)
-
Serial Cable
- Used to connect the evaluation board’s DB9 connector and the serial interface card (DB9 connector). If the PC does support serial interface, use the RS-232 to USB converter.
-
Optional: USB type B cable (for debug message)
- Used to connect the evaluation board’s USB connector and the PC’s USB connector.

Step 2: Power on
Connect the 5V power adaptor or USB cable to the evaluation board and turn on the power switch.
- The power LED will turn red once the evaluation board is on.
Step 3: Search
Open the configuration tool and click the search button. If the board is turned on and connected to the same network, the MAC address or settings of the WIZ750SR-100 module can be checked using the configuration tool.

Step 4: Set up your WIZ750SR-100
Change the settings accordingly to the customer’s environment. The test shown in this document is based on factory setting.
* Click the **setting** button to apply the changes in settings of the configuration tool.
Step 5: Connect
Connect the PC as the TCP client of the user’s serial device for data communication testing. In order to do this, the serial terminal program / TCP client terminal program must be opened on the PC. The serial terminal program and TCP client program must be set as below.
- Serial terminal program: 115200-8-N-1, Flow control: None
- TCP client program: 192.168.11.2:5000 (The IP address and port number of WIZ750SR-100)
The COM port for serial terminal program connection can be checked as below.
- Control Panel > System > Device Manager

Step 6: Verify
The basic data communication of the WIZ750SR-100 can be verified as below.
-
Serial to Ethernet: data communication verification
- Enter the character string in the serial terminal and check if the identical character string appears on the TCP client terminal.
-
Ethernet to Serial: data communication verification
- Enter the character string in the TCP client terminal and check if the identical character string appears on the serial terminal.
Step 7: Done
Now you’re ready to use the WIZ750SR-100!
-
This document is based on the assumption of the PC as the serial device / remote network device.
-
The next step is to connect the WIZ750SR-100 module to the target serial device and check if the device can communicate, control, and monitor via the remote PC or monitoring server.
