Windmill COMIML: Windmill 6 with the Serial Driver

COMIML lets you read and control almost any serial device communicating over RS-232, RS-422, RS-485 or Modbus. These include such diverse equipment as electronic balances used in a laboratory, GPS receivers used in the field and data loggers used in process plant. The COMIML driver reads data from your PC's COM port, and passes it to the Windmill 6 logging, charting and display programs (which are included with COMIML). You can also use other Windows software, like Excel or Access, to display and analyse the data.
Price: 145 GB pounds.

Try Before You Buy

You enter all your serial communications settings with a program called comDebug. comDebug saves your settings in a file which is then used by the COMIML device driver. To enable you to test whether Windmill will work with your device, you can download a free copy of comDebug! To register for your free copy fill in this form.

Examples of Devices that you can read with COMIML

COMIML can control both those devices that continuously output data values as though to a printer, and those that require a command message each time data values are needed. It can understand both ASCII and binary messages, and insert cyclic redundancy checks. With a flexible approach to building command strings, and parsing the received data strings to extract data values, the majority of instruments are supported. These include GPS, sonar, gas analysers, pH transmitters, power meters, titrators, particle analysers, conductivity meters and laboratory scales.

You have the freedom to mix and match equipment from many different manufacturers in many combinations. For example, serial devices from Anton Paar, Ashtec, Bruël & Kjær, Dataq Instruments, Datel, Datataker, Denver, Desoutter, Ecom, Edge Tech, Electro Industries, Fisher, Furuno, Garmin, Horiba, Mettler Toledo, Microchip, Motorola, Molyteck, Omron, Orion, Parallax, Paroscientific, Patton, Phytron, Quantum Logic, Quest Scientific, Sartorius, Siemens, Telegan, Telemecanique, Texas Instruments, Transcell, Tritech, TTi, TSS, Varian SenTorr, Veris, Weeder Technologies, Weilheimn, WTW and World Precision Instruments have all been handled by Windmill. Many channels of data can be accepted from each instrument.
