Self-Transmission Test

• Short-circuit the TXD and RXD of the USB TTL PRO.
  • TXD - RXD
  • For testing hardware flow control, connect as follows:
    • CTS - RTS
• Connect the module to the computer using a USB cable, open the serial port debugging assistant, and select the corresponding port number.
• Send data to the USB TTL PRO through the serial port debugging assistant and observe if the receiving window of the assistant receives the same data as the sending end.

Hardware Connection

• 

Note

• When using the TTL side for communication, a common ground connection must be established. That is, the GND on the TTL side of the module must be connected to the GND of the TTL device.

Driver Installation

1. Download and install the Diver。

2. Verify if the driver is installed successfully. Right-click the Windows logo in the bottom left corner and open "Device Manager".

Expand "Ports (COM & LPT)". If there is a "USB Serial Port" device, the installation is successful.

3. Verify if the module is working properly. Short-circuit the TXD and RXD pins of the module, open theserial port debugging software， , and click "Open Serial Port". Enter any content in the text box, then click the "Send" button. Under normal circumstances, the software will receive and display the same content.
