The RS-232/TTL version of WIZ750SR-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.
Connect the WIZ750SR module to evaluation board and also the cable as shown in the picture below.
Connect the 5V power adaptor or USB cable to the evaluation board and turn on the power switch.
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 module can be checked using the configuration tool.
Change the settings accordingly to the customer’s environment. The test shown in this document is based on factory setting.
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.
The COM port for serial terminal program connection can be checked as below.
The basic data communication of the WIZ750SR can be verified as below.
Now you’re ready to use the WIZ750SR!
