MadgeTech's IFC200 interface cable communicates between stand-alone data loggers and the MadgeTech software. Through this interface, loggers can be started, stopped, or downloaded. The IFC200 has been redesigned and is now plug-and-play. It can be directly connected to a computer without installing any drivers and is compatible with Windows XP SP3, Windows Vista (32 and 64-bit), and Windows 7 (32 and 64-bit) operating systems. The improved IFC200 can now operate at up to 500 Volts RMS relative to the computer's earth ground when attached. The IFC200 is equipped with communication LEDs, that provide a quick indication of the device status. The blue light illuminates when the device is plugged in and successfully recognized by Windows. The red light flashes when data is sent, and the green light flashes when data is received.
