InstruNet provides tens of microvolts of absolute accuracy instead of tens of millivolts, at the same cost and at the same throughput rates as typical general purpose data acquisition boards. It does this with a completely different topology where the analog electronics are close to the sensor in electrically quiet boxes outside your PC, and noisy digital electronics are left inside the computer. The external boxes contain signal conditioning amplifiers for each channel and can directly attach to sensors such as thermocouples, thermistors, RTDs, strain gages, resistance sources, current sources and voltage sources. The box returns engineering units to your PC (e.g. ░C, Volts, Amps). At the heart of the real-time system is a PCI or PC-card controller board that plugs into a Windows 95/NTx86 or Macintosh computer. Each controller contains a 32 bit microprocessor with 256KB of RAM that manages the external networks of devices. All real-time tasks are off-loaded to this processor, therefore the host computer is not burdened with real-time issues. Each instruNet iNET-100 box provides, 16 single-ended/8 differential analog inputs, 8 analog outputs and 8 digital I/O lines.
iNET-100 includes 44 screw terminals. The iNET-100B version adds 16 BNCs for analog inputs. The controllerÆs themselves provide 10 counter/timer channels each of which can function as a digital input bit, a digital output bit, a clock output channel or a period measurement input channel. low-pass, high-pass, band-stop and band-pass filters; where the filter specification for each channel is independently set in software. Each channel provides a programmable analog low pass filter with programmable A/D measurement integration time. The programs instruNet includes drivers callable from any 32 bit C compiler, and Visual Basic (v4.0 or greater).
SOFTWARE
'InstruNet World' is a FREE application program. It manages, monitors and operates the instruNet
system. It digitizes long continuous waveforms, spools them to disk,
views incoming waveforms in real-time and then allows post acquisition viewing, much like an
oscilloscope or strip chart recorder. InstruNet World provides a spreadsheet-like environment where
one can set and view channel parameters such as sensor type, integration time, analog filter, and
digital filter. Each channel has itÆs own row in the spreadsheet, with the various options in the columns.
instruNet is also compatible with a variety of off-the-shelf software products including TEST Point,
HPVEE, SuperScope II Macintosh; Microsoft Excel 8 for Windows, DasyLab and Labtech Notebook
(consult the factory for the availability of DasyLab and Labtech drivers).
For users writing their own programs, instruNet includes drivers callable from any 32 bit C compiler, and Visual Basic (v4.0 or greater). The driver includes a main routine, called 'iNet( )', that reads or writes any of the options or channels on the system. Optional drivers are also available for LabVIEW software.
