What Serial Port Monitor customers say
Useful RS-232 Terminal
This terminal is very straight forward and useful for opening COM ports, monitoring ASCII data, and exporting the file.
Simple monitoring and exporting of ASCII data
This is a simple and straight forward monitoring SW that allows you to open COM ports, monitor, and export the data. It addresses my needs perfectly.
A great tool for serial port monitoring
Serial Port Monitor is an essential tool for debugging and monitoring devices that use serial port.
I have used it for analyzing the data messages from Radon sensors.
Serial Port Monitor Enables A PLC to MODBUS RTU Communication
I had been looking for a method to have my JS application communicate to a PLC via the MODBUS RTU protocol. While I was able to communicate the PLC through MODBUS TCP protocol, I was unable to revise the code to function with the MODBUS RTU and so they have not been able to locate each other.
Multiple attempts to connect my PLC to the MODBUS RTU ended with time-out errors unless I rebooted the unit. Obviously, I was frustrated and desperate for a solution.
I eventually came across the Serial Port Monitor after trying dozens of options, including multiple MODBUS emulators, with no luck at all. I found that the Serial Port Monitor helped me analyze exactly where the COM port error was coming from and helped me figure out how to establish communication with MODBUS RTU.
Serial Port Monitor Helped Me Build A Custom Dashboard on Windows
I wanted to build a custom dashboard for a 3rd-party Li-Ion Battery Management System. The system was based on Texas Instruments BQ76940 and Atmel 8-bit line of microcontrollers.
While I received a brief explanation of the communication protocol, it wasn’t near enough information for the task at hand. This meant being able to analyze the transmitted protocol while using the Windows-based dashboard provided by the manufacturer was a non-negotiable- and urgent- necessity.
After researching several different softwares that just didn’t seem to be what I was looking for, I found Serial Port Monitor. Upon reading into the software, I found that this unique SPM was able to “sniff” out any open serial ports on the Windows platform. This meant that Serial Port Monitor was exactly the tool that I needed to complete the project successfully and easily.
Thanks to this SPM, I have no problem seeing the protocol flow in real time, and can now fully understand the documentation being recorded. If not for SPM, I would have wasted countless hours trying to deal with trial and error during the programming. I’m very pleased that this all-in-one software will be a tool in my programmer’s belt that I can call upon many times in the future.
