Re: [PSUBS-MAILIST] Sensor Interfacing
Hi Peter,
Try National Instruments at http://www.ni.com/. I have used their products
on past projects at Sun. The product line in hardware and software is
primarily directed to the PC platform. PCI and ISA are the primary interfaces
into a PC. The other end are DAC, ADC, relays, sensors, GPIB controllers....
To quote from their web page:
GPIB (IEEE 488) instruments are the most popular, worldwide standard for test and measurement systems. As the leading supplier of GPIB interface products, NI offers a solution for almost every desktop, laptop, industrial PC,
workstation, and interface bus including PCI, PXI, CompactPCI, PCMCIA, USB, RS232/485, FireWire, Ethernet, VXI, and VME. Our latest GPIB (IEEE 488) interface produc
