    Chapter 1 The CB-100 is useful for initial prototyping of an application or in situations where PC-DIO-96 interconnections are frequently changed. Once a final field wiring scheme has been developed, however, you may want to develop your own cable. This section contains information for the design of custom cables.

  • Page 19: Chapter 2 Configuration And Installation

    The DIP switch and jumper are shown in the parts locator diagram in Figure 2-1. The PC-DIO-96 is configured at the factory to a base I/O address of hex 180 and to interrupt level 5. These settings (shown in Table 2-1) are suitable for most systems. However, if your system has other hardware at this base I/O address or interrupt level, you need to change these settings on the PC-DIO-96 (as described in the following pages) or on the other hardware.

  • Page 20: Base I/O Address Settings

    I/O address settings is hex 000 through 3E0. Base I/O address values hex 000 through 0FF are reserved for system use. Base I/O values hex 100 through 3FF are available on the I/O channel. A4, A3, A2, A1, and A0 are used by the PC-DIO-96 to decode accesses to the PC-DIO-96 User Manual ©...

  • Page 23: Interrupt Level Selection

    Chapter 2 Interrupt Level Selection There is one set of jumpers for interrupt selection on the PC-DIO-96 board. W1 is used for selecting the interrupt level. The location of this jumper is shown in Figure 2-1. The PC-DIO-96 board can connect to any one of six interrupt lines of the PC I/O Channel: IRQ3, IRQ4, IRQ5, IRQ6, IRQ7, or IRQ9.
