Free serial port monitor software lets you troubleshoot communications problems and log data from RS232, RS422, RS485 and Modbus instruments. Control the state of the PC's com port output lines and see the state of the port input lines. Free technical support for life. Understands ASCII, hexadecimal or binary data. Data logging to text files. 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 GPS, PICs, scales, balances, RFID readers, pH transmitters, data loggers, titrators, particle analysers, PIC microcontrollers, pressure transmitters, water baths, hygrometers, oxygen electrodes, I2C devices, plcs 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, Daily RFID, Dataq Instruments, Datel, Datataker, Denver, Desoutter, Ecom, Edge Tech, Electro Industries, Fisher, Furuno, Garmin, Honeywell, Horiba, Mettler Toledo, Microchip, Motorola, Molyteck, Newmar, NovAtel, Nu-Metrics, Omnistar, Omron, Orion, Parallax, Paroscientific, Patton, Phytron, Quantum Logic, Quest Scientific, Sartorius, Siemens, Telegan, Telemecanique, Texas Instruments, Transcell, Tritech, TTi, TSS, Turner Designs, 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
