ComDebug Features

• No programming required
• Free technical support for life
• For instruments communicating over RS232, RS422, RS485, Modbus and TCP/IP
• Understands ASCII, binary and hexadecimal data
• For serial instruments that continually send data and those that need prompting
• Quickly identify and correct communication errors
• Insert cyclic redundancy checks (CRCs)
• Send ASCII values, 16-bit 2s complement integers, unsigned integers, single bits of data, floating point etc, to instruments
• Control the state of the PC's serial port output lines
• See the state of the serial port input lines
• See all bytes sent and received, even non-printing characters like carriage returns. This is crucial when dealing with binary data.
• Send acknowledgements
• For Windows 8, 7, Vista, XP, 98 and 95
• Data logging from one instrument.
• Optionally, with the Windmill COMIML serial driver, continually send data from up to ten instruments to the Windmill logging, charting and other data acquisition applications, or to other Windows software like Excel. The ComDebug download is packaged with a month's trial of the Windmill and COMIML software.

No Programming Required

Simply select your communication settings or type your instrument's commands: no need for any programming.

What sort of Devices can you Read with ComDebug?

With ComDebug you can control both those serial devices that continuously output messages, and those that require commands before supplying data. With a flexible approach to building command strings, and parsing the received data strings to extract data values, the majority of analytical instruments are supported. These include altimeters, balances, conductivity meters, data loggers, dial gauges, digital indicators, digital thermometers, DMR, extensometers, flaw detectors, fluorometers, force gauges, gas analysers, GPS, gyro compasses, hygrometers, I2C devices, ion gauges, load meters, motion sensors, multimeters, myographs, oxygen electrodes, particle analysers, pH meters, PIC microcontrollers, plcs, pressure transmitters, power analysers, RLC meters, RFID readers, thermoregulators, titrators, solar panel array controllers, sonar and water baths.

You have the freedom to mix and match equipment from many different manufacturers in many combinations. For example, serial devices from Acculab, A&D, Advantec, Ashtec, Avery Berkel, B&B Electronics, Bruël & Kjær, Campbell Scientific, Crosstalk Security, Dataq Instruments, Daily RFID, Dataq Instruments, Datel, Datataker, Denver, Desoutter, Ecom, Fisher, Fluke, Funaro, Garmin, Honeywell, Horiba, Humminbird, ICP DAS, Linkcom, Magellan, Maxim, Mettler Toledo, MecMesin, Metrix, Microchip Technology, Mitutoyo, Motorola, Molytek, Newmar, NovAtel, NovAtel, Nu-Metrics, Omnistar, Omron, Orion, Panametrics, Parallax, Parker, Protek, Quantum Logic, Remontec, Rockwell, San Jose, Sartorius, SecuMaster Technologies, SG Brown, Siemens, Sokkia, Sylvac, Telegan, Transcell, Tritech, TTi, TSS, Turner Designs, Varian SenTorr, Veris, Voltcraft, Weeder Technologies, Weilheimn, WTW and World Precision Instruments have all been handled by Windmill. Many channels of data can be accepted from each instrument.

"I would recommend ComDebug to any one who has to trouble shoot a serial card problem. I used it to locate a defective com card which the manufacturer said could not be. "
Doyal J. McVicker Jr.

"Your software works great; it's the only package that allows me to set the DTR line low...required by the TI (Texas Instruments) development board configuration."
