PC Settings

Double check that the WIZ752SR-120 and the PC, or laptop you are using to set up WIZ752SR-120 with are both on the 5same Ethernet network.

Example: PC Network Settings

* When the WIZ750SR's settings are factory default,

Network Settings PC or laptop
(= Remote)
IP address 192.168.11.3 -

  • User should to matching the network settings of 'WIZ750SR-120's remote host' and 'PC (or laptop)' for testing TCP client/mixed mode.
  • If the DHCP(automatic IP allocation) is used, both the WIZ752SR-120 and test PC must be set to be assigned the same IP from the same router.

Connecting Steps

The WIZ752SR-125 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 WIZ752SR-125 module to 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.

Step 2: Power on

Connect the 5V power adaptor 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 WIZ752SR-125 module can be checked using the configuration tool.

Step 4: Set up your WIZ752SR-125

Change the settings accordingly to the customer’s environment. The test shown in this document is based on factory setting.

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)

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 WIZ752SR-125 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 WIZ752SR-125!

  • This document is based on the assumption of the PC as the serial device / remote network device.
  • The next step is to connect the WIZ752SR-125 module to the target serial device and check if the device can communicate, control, and monitor via the remote PC or monitoring server.
