How to Set the Communication Baud Rate of the VFD Guest Display
The "baud rate" refers to the speed at which data is transmitted over a serial communication channel. It represents the number of signal changes per second and is crucial for ensuring proper communication between devices. When working with serial port devices, it's essential that both the upper computer (host) and the lower device (such as the VFD guest display) use the same baud rate. This ensures accurate and stable data exchange, making it an important step when configuring the system.
So, how can you adjust the baud rate on the VFD220? First, you need to understand the specific commands required for changing the baud rate. The process typically involves sending a command through a serial communication interface. Below is a summary of the necessary steps:
To modify the baud rate, you'll need a serial debugging tool. Connect your computer to the VFD guest display using a serial cable. Open the serial communication software on your computer and configure the port settings. Make sure the baud rate in the software matches the current setting of the VFD. Then, send the appropriate command to change the baud rate. Once the command is successfully executed, the VFD will update its communication settings accordingly.
It’s also important to note that different models of VFD displays may use slightly different command formats or protocols. Always refer to the user manual or technical documentation provided by the manufacturer to ensure accuracy. Testing the new baud rate after the change is recommended to confirm that the communication is working properly.
By following these steps carefully, you can effectively adjust the baud rate of the VFD guest display and ensure smooth and reliable communication with your control system.
