    A good signal connection can avoid unnecessary and costly dam- age to your PC and other hardware devices. This chapter provides useful information on how to connect input and output signals to the PCL-722 via the I/O connector. 3.2 Switch & Jumper Settings The PCL-722 card has two function jumper settings.

    I/O space. Some I/O address locations will be occupied by internal I/O and your peripherals. In order to avoid conflict with these devices, the PCL-722 address can be set by a 6 position DIP switch and placed anywhere in the IBM PC decoded external UO space.

  • Page 24: 96/144-Bit Mode Setting

    3.2.2 96/144-bit Mode Setting The PCL-722 can limit the 32 required addresses to 16, there- fore, the digital I/O is limited to 96 bits. SW2 (see Fig. 3.2 below) sets the number of usable I/O. The PCL-722 card should be left in the 144 bit mode unless this address con- flicts with the addresses of other peripherals already installed or those to be installed in neighbouring slots.

  • Page 25: Interrupt Settings

    You can set the address according to the information given in Table 3.1. 3.2.3 Interrupt Settings Pins PC-0 and PC-3 of each channel of the PCL-722 generate hardware interrupts and can be set to any of the interrupt request lines IRQ2, 3, 4, 5, 6 and 7.

    3.3 Signal Connections The PCL-722 card emulates MODE 0 of 8255 PPI, and is pin compatible with popular industrial solid state I/O racks and modules such as those manufactured by OPTO-22, Potter Brumfield, Gordos, and others. The PCL-722 has six 50-pin male IDC connectors that inter- face with position OPTO-22 racks 8, 16 and 24.

  • Page 29: Interrupt Handling

    3.4 Interrupt Handling The PCL-722 has two lines (PC-0, PC-3) for each channel to generate hardware interrupt. The interrupts are edge-triggered. PC-0 traps a rising edge signal, while PC-3 traps a falling edge signal. To use the interrupts, simply insert the appropriate IRQ jumper to select the desired interrupt level (IRQ 2-7).
  • Page 30 For example, lxx0 (1000, 1010, 1100, 1110) Although interrupt signals are normally received from external peripherals, the PCL-722 can also execute a (test) output signal to simulate an interrupt being inputted from an external device. See the example in Appendix.
