Product Features
- Adopts industrial-grade chips FT232 and SP3232 for high-speed, stable, reliable, and compatible communication.
- Equipped with USB-B interface and DB9 male connector, allowing for smooth and secure plugging and unplugging.
- Features independent power and signal isolation circuits.
- Incorporates an electrostatic ESD protection circuit on the USB side to effectively prevent electrostatic damage and protect downstream circuits and devices.
- The RS232 side RXD, TXD, RTS, and CTS pins are equipped with overcurrent and electrostatic protection circuits.
- Baud rate support range: ≤150K bps
- Onboard five LED indicators for indicating the transmission and reception status of circuit signals.
- PWR light: Green, power indicator
- TXD light: White, RS232 data transmission indicator, data flow: USB->RS232
- RXD light: White, RS232 data reception indicator, data flow: RS232->USB
- RTS light: White, request to send indicator, used to indicate that the device is ready to receive data
- CTS light: White, clear to send indicator, used to determine if data can be sent to the other party
Self-transmission Test
- Short-circuit pins 2 and 3 of the USB 232 PLUS
- TXD (pin 3) - RXD (pin 2)
- For hardware flow control, connect as follows:
- CTS (pin 8) - RTS (pin 7)
- 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 232 PLUS 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 232 side for communication, a common ground operation must be performed, i.e., the GND (pin 5) on the 232 side of the module must be connected to the GND of the 232 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.
