    Two other features give the PCI-1751 practical advantages in an industrial setting. When the system is hot reset (the power is not turned off) the PCI-1751 retains the last I/O port settings and output values if the user has set jumper JP4 to enable this feature.

    Touch the metal part on the surface of your computer to neutralize the static electricity that might be on your body. Insert the PCI-1751 card into a PCI slot. Hold the card only by its edges and carefully align it with the slot. Insert the card firmly into place. Use of excessive force must be avoided, otherwise the card might be damaged.

    PCI-1751 via the I/O connector. Switch and Jumper Settings We designed the PCI-1751 with ease-of-use in mind. It is a "plug and play" card, i.e. the system BIOS assigns the system resources such as base address and interrupt automatically.
  • Page 19 Jumper JP4 gives the PCI-1751 a new and valuable capability. With JP4 enabled, the PCI-1751 "memorizes" all port I/O settings and output values, and, in the event of a "hot" reset, the settings and output values present at the port just prior to reset are restored to each port following reset.

    Digital I/O Ports Introduction The PCI-1751 emulates two 8255 programmable peripheral interface (PPI) chips in mode 0, but with higher driving capability than a standard 8255 chip. Each of the 8255 chips has 24 programmable I/O pins that are divided into three 8-bit ports. The total 48 DI/O pins from both chips are divided into 6 ports, designated PA0, PB0, PC0, PA1, PB1 and PC1.

  • Page 23: Timer/Counter Operation

    Timer/Counter Operation Introduction The PCI-1751 includes one 8254 compatible programmable timer/counter chip which provides three 16-bit counters, designated as Timer 0, Timer1 and Counter 2. Each has 6 operation modes. Timer 0 and Timer 1 can be used separately or can be cas- caded to create one 32-bit timer.

    Counter 2) are connected to the interrupt circuitry. The "Interrupt Control Regis- ter" of the PCI-1751 controls how the combination of the 6 signals generates an inter- rupt. Two interrupt request signals can be generated at the same time, and then the software can service these two request signals by ISR.

    10 MHz input frequencies to the counter chip from an on-board crystal oscillator. On the PCI-1751, the 8254 chip's Timer 0 and Timer 1 can be used separately or can be cascaded to create a 32-bit programmable timer by setting JP2. When the clock source of Timer 1 is from an external source, you can user Timer 0 and Timer 1 as two independent 16-bit timers.

    This is accomplished by decreasing the counter by two on the falling edge of each clock pulse. When the counter reaches the terminal count, the state of the output is changed, the counter is reloaded with the full count and the whole pro- cess is repeated. PCI-1751 User Manual...

    Counter Applications The 8254 compatible programmable interval timer/counter on your PCI-1751 inter- face card is a a very useful device. You can program timers 1 and 2 to serve as tim- ers, event counters, square wave genera- tors, or as a watchdog to generate regular interrupts at a fixed interval.
