Welcome to Windmill Software's Data Acquisition site where you will find measurement & control articles and Windmill's free data logging software.
Download the free ComDebug software to trouble-shoot serial communications and log data from almost any measurement instrument which communicates over RS232, RS422, RS485, Modbus or TCP/IP. For logging from many serial instruments at once, download a free trial of our Windmill 7 data acquisition software with charting, output control. You can save data in text files or transfer directly to Excel or other software.
Just want some information? You've come to the right place. We have hundreds of articles on data acquisition and control.
