Comprar
 
64 digital I/O channels, 3 counter/timers, 2 ESSI ports, four high-speed IRQ lines (100 nS) PCI digital I/O lab board.
 
Characteristics:
  • For PCI bus
  • 64 lines (5 V/TTL) of I/O in 16-bit ports
  • Generate interrupts on any line
  • Four separate high-speed IRQ lines (100 ns)
  • User-defined power-up state in 16-bit groups (High, Low, Tri-stated)
  • Two Enhanced Synchronous Serial Interfaces (ESSIs) for high-speed devices such as codecs
  • Three clock/interrupt lines, three 24-bit counters/timers
  • Onboard 16-bit FIFO: 2k samples
  • Port-scan list
  • PowerDAQ Software for Windows NT/2000/XP and Linux/RTLinux
