Descrição
The OMK-AD812 is a low cost data acquisition system compatible with most IBM personal computers and compatibles. It plugs directly into the personal computer’s parallel port and derives it’s power from the parallel port’s signal lines. It may be used with desktop PCs or because of its compact size it is ideally suited for field use with a portable computer.The OMK-AD812 is an inexpensive, low speed data acquisition product that is very easy to use. Simply plug it in, load its software, connect your devices and you are ready to begin acquiring data. The OMK-AD812 works under Windows 95/98/NT 4.0/2000 and Me. Custom application development with Microsoft Visual Basic, Microsoft Visual C++, Borland C++ Builder, Borland Delphi and others is supported with a simple to use ActiveX control. The OMK-AD812 includes eight single-ended analog input channels that can also be used in pairs as differential analog inputs. The maximum sampling rate using the standard software package is 50 samples/sec. The 12 bit resolution combined with the OMK-AD812’s fixed 0 to 4.096V full-scale input range provides a resolution of approximately 1 mV. The OMK-AD812 also includes four digital I/O lines. These four lines can be used for input or output.
