Serial Port Monitor

Here is a review of what I did during the trial period reverse engineering and debugging modbus diesel generator controller and relay boards for my amateur radio station.
Using Electronic Team’s Serial Port Monitor has been extremely useful in debugging and reverse engineering cheaper modbus equipment for control and automation using node-red. The cheaper hardware usually comes without any documentation at all, but in some cases with demo programs. Running Serial Port Monitor, hooks into the actual serial port without any problems or need for virtual ports. And multiple views for presenting the data. Another very useful feature is to save the session. So when equipment is connected to network gateways, I can always go back to my recordings to verify what actually happened. Also works nice with Moxa serial port servers, and the open port and monitor function lets me remotely debug in the real gateway driven bus, comparing data with working saved session. I have not found any tool as easy and versatile as this for rs-232, and rs-485 modbus monitoring.

I’m a gardener and hobbyist in electronic engineering. My recent project is to develop a working control for my irrication system based on LoraWan devices and Modbus sensors. Before purchasing the Serial Port Monitor I worked with some Modbus simulators and scanners for troubleshooting and debugging. Now with Serial Port Monitor it is much more easier and effectively.
A great tool.

We make extensive use of this software utility to monitor and log serial port traffic when testing third-party programs. It’s a great tool for troubleshooting serial protocols or reverse-engineering undocumented functions in software products.

I was looking for a lightweight app for incoming and outcoming data monitoring between Ant and COM port with a hardware device attached to it that communicates with the software.
Serial Port Monitor worked just fine for that purpose.

This terminal is very straight forward and useful for opening COM ports, monitoring ASCII data, and exporting the file.
