CIO-DAS08 Medium Speed, 8 Channel Analog Input, 3 Counters, 31 Digital I/O DESCRIPTION The CIO-DAS08 is supported by a broad range of software to allow The CIO-DAS08 multifunction analog and digital I/O board is programmed control in BASIC, C, Windows and PASCAL. Many designed to be compatible with MetraByte's popular DAS08. menu controlled data logging, analysis and control programs are available from a number of third party developers. In fact, any Installed in any IBM PC/XT/AT/PS30 or compatible computer the software designed for MetraByte's popular DAS-08 will work with CIO-DAS08 turns your personal computer into a medium speed the CIO-DAS08; we guarantee it! data acquisition and control station suitable for laboratory data In addition, the CIO-DAS08 comes with a complete PIO-12 com- collection, instrumentation, production test, or industrial moni- patible 8255 and 37 pin connector! toring.
