Logs peak and average transfer rates for performance analysis.
A factory automation engineer notices intermittent communication failures on an RS-485 network running Modbus RTU. By attaching Serial Bandwidth Monitor 3.4 to the master port, they observe that the poll/response cycle suddenly spikes to 100% bandwidth utilization every 30 seconds. This reveals a rogue slave device flooding the line – something a protocol analyzer might miss.
: Match the serial configuration precisely (e.g., 115200 Baud, 8 Data Bits, No Parity, 1 Stop Bit) within the application's connection panel.
When developing firmware for microcontrollers (e.g., STM32, Arduino, PIC), developers often implement debug prints. A "Serial Bandwidth Monitor" helps developers answer the question: "Is my debug output slowing down the main application loop?" By measuring the bandwidth of the debug stream, developers can quantify the overhead of their logging system and optimize string lengths or baud rates accordingly.
In manufacturing environments utilizing Modbus RTU or Profibus over RS-485 networks, long cable runs and electrical noise cause transmission retries. Serial Bandwidth Monitor 3.4 helps field technicians quantify how environmental noise impacts effective bandwidth, allowing them to optimize termination resistors or adjust polling intervals scientifically.

Serial Bandwidth Monitor 3.4 bridges the gap between hardware serial communication and modern network diagnostics. By providing clear visibility into the otherwise hidden throughput of COM ports, it eliminates the guesswork from serial port debugging, saving development time and preventing system downtime.
: Can run as a system service to monitor traffic and generate reports automatically without a user being logged in. Compatibility
: Exact, precise bit-and-byte counts provide the granular precision required to track micro-transactions on the wire.
: In networking contexts, "serial links" often default to a bandwidth of 1.544 Mbps Logs peak and average transfer rates for performance
Based on testing and user feedback, the Serial Bandwidth Monitor 3.4 demonstrates:
A: The serial filter driver may not be loaded. Reinstall the software with antivirus temporarily disabled. Then run sc query sbmfilter in an admin command prompt to verify.
Generates daily, weekly, and monthly reports to aid in long-term performance auditing.
transforms an opaque serial link into a transparent, measurable data channel. Its combination of real-time graphing, non-intrusive sniffing, and flexible logging solves problems that generic terminal tools cannot touch. This reveals a rogue slave device flooding the
This public link is valid for 7 days and shares a thread, including any personal information you added. This link or copies made by others cannot be deleted. If you share with third parties, their policies apply. Can’t copy the link right now. Try again later.
: It generates detailed reports on a daily, weekly, and monthly basis, which can be exported to common formats like .csv , .txt , or .html .
A firmware developer is writing a bootloader for an STM32 microcontroller. They use the tool to measure the exact bandwidth achieved over a 115200 baud UART during a firmware upload. Finding a 15% discrepancy between theoretical and actual throughput, they identify a missing hardware flow control (CTS/RTS) line. Enabling flow control restores full speed.
: Bandwidth Monitor 3.4 operates as a system service, allowing for 24/7 monitoring without requiring a user to be logged in. Compatibility
Version 3.4 typically supports raw data capture. It measures the bandwidth of the entire stream, including overhead bits (start, stop, and parity bits), providing a "wire speed" measurement rather than just application-layer speed.
