UART
UART (Universal Asynchronous Receiver/Transmitter) panel provides users with asynchronous serial communication testing. You can set baud rate, parity check, and other parameters to perform data transmission and reception.
Supported Products and Ports
This function supports devices equipped with UART interface. Please confirm the corresponding Port number according to your device model:
| Product Name | Port |
|---|---|
USB-DAQ-F1-AD | 1~2 |
USB-DAQ-F1-AOD | 1~2 |
USB-DAQ-F1-CD | 1~2 |
USB-DAQ-F1-D | 1~2 |
USB-DAQ-F1-RD | 1~2 |
USB-DAQ-F1-TD | 1~2 |
Parameter Settings
Before opening the port, please set the communication protocol parameters:
| Parameter | Description |
|---|---|
| Baud Rate | Transmission rate (bits per second), e.g., 9600, 115200. |
| Data Bit | Data bit length, usually 8 bits. |
| Parity | Parity check bit (None, Odd, Even), used for error detection. |
| Stop Bit | Stop bit length (1, 1.5, 2), used to indicate the end of data frame. |
