Device Monitoring Studio Reviews

This enables us to examine Modbus data for HMI/PLC communication where we do not have the hmi source code. We can generate a new address and data map for upgrade of the HMI. This would be impossible without Device Monitoring Studio.

Without a physical serial port monitoring device such as a lineeye-210, I can analyze data flow between the diagnostic software and the controller board using the RS-232 port. After evaluation of Device Monitoring Studio, I concluded to get it.

I was looking for USB monitoring software to troubleshoot USB device performance issue. We used the trial version to have a quick look: easy to use and provides all technical information on the protocol. This tool helped us to quickly understand the performance issue related to the operating system driver. We have tested several solutions and selected your product as the best one to fine-tune our software. I convinced my boss to purchase this tool for us to make our team more efficient in development.

I've been demoing many USB Data Sniffers and Analysers on the market and have found HHD Software's Device Monitoring Studio to be the best product available and it is well priced in comparison to the competitor's offerings. I've been using it to monitor and log USB traffic between software applications and connected hardware.

I develop a software to read data from electric energy meters. The meters use the standard ANSI C12.21 and your software helps me follow how the PC communicates via serial interface (direct RS485 or via GSM modem) with the energy meters.
Your software is very useful to confront the theory (documentation of the standard) with the real communication process. It helps me to track errors and, most usefully, it has very precise packet time stamps.

I've used this product at a previous company and I bought it for myself so now I benefit from it where ever I go. I also owned an expensive Beagle analyzer (over $1K). I sold it and use the Studio now. It makes me like super man.
