# Why Our Product Supports a Maximum Baud Rate of 115200

Our product supports serial communication up to 115200 bps. Learn why this industry-standard speed is reliable, stable, and enough for most RS-232 applications.

Why Our Product Supports a Maximum Baud Rate of 115200

Many customers ask why our product supports a maximum baud rate of 115200 bps. The answer is simple: 115200 bps is the most widely used high-speed setting in industrial serial communication, and it offers the best balance between speed and reliability.

What Is a Baud Rate?

A baud rate is the speed at which data is transferred over a serial port, measured in bits per second (bps). Common settings include 9600, 19200, 38400, 57600, and 115200 bps. The higher the baud rate, the faster the data travels — but also the more sensitive the signal becomes to noise, cable length, and electrical interference.

Why 115200 bps Is the Best Choice

Industry standard — 115200 bps is the default "high-speed" setting supported by almost all industrial devices, PLCs, sensors, instruments, and PC software.

Proven reliability — At 115200 bps, RS-232 signals remain stable even over longer cables and in electrically noisy environments.

Lower error rate — Faster speeds above 115200 bps (such as 230400, 460800, or 921600 bps) are more likely to cause data loss or communication errors, especially on long or low-quality cables.

Wide compatibility — Nearly all debugging tools, host software, and terminal programs work smoothly at 115200 bps.

Is 115200 bps Fast Enough?

For most applications, yes. Typical industrial data — sensor readings, control commands, status messages, and logs — is very small in size. At 115200 bps, the port transfers about 11 KB of data per second, which is far more than these applications need. Choosing a higher baud rate would bring no real benefit, only a higher risk of errors.

Recommended Settings

For the best experience, we recommend: Baud rate 115200 bps, Data bits 8, Parity None, Stop bits 1, Flow control None. These settings work well for the vast majority of devices and software.

Conclusion

Our product is designed around 115200 bps because it is fast enough for real-world applications, stable in industrial environments, and compatible with nearly everything on the market. If you need help configuring the communication settings, feel free to contact our support team.
