I/O wiring connections are via a 100-pin high-density connector. If an IDC type mating connector is used then two flat 50 wire ribbon cables can connect these cards to termination panels. Also, this provides compatibility with A24A, OPTO-22, Gordos, Potter & Brumfield, et al solid-state-module mounting racks. Every second conductor of the flat cables is grounded to minimize crosstalk between signals in the cables. -

Page 9: Chapter 2: Installation
Chapter 2: Installation A printed Quick-Start Guide (QSG) is packed with the card for your convenience. If you’ve already performed the steps from the QSG, you may find this chapter to be redundant and may skip forward to begin developing your application. - Page 10 Hardware Installation Make sure to set switches and jumpers from either the Option Selection section of this manual or from the suggestions of SETUP.EXE. Do not install card into the computer until the software has been fully installed. Turn OFF computer power AND unplug AC power from the system. Remove the computer cover.

Page 11: Chapter 3: Option Selection
Chapter 3: Option Selection Refer to the setup programs on the CD or diskettes provided with the card. Also, refer to the block diagram on the previous page and the option selection map on the following page when reading this section of the manual. External Interrupts are accepted on the I/O connector pin 9 (bit C3 group 0) and pin 59 (bit C3 group 1). -
Page 12: Chapter 4: Address Selection
Chapter 4: Address Selection These cards use one address space, occupying sixteen consecutive register locations. PCI architecture is inherently plug-and-play. This means that the BIOS or Operating System determines the resources assigned to PCI cards rather than requiring the user to select those resources with switches or jumpers. -
Page 13: Chapter 5: Software
Chapter 5: Software The following paragraphs describe the setup program, then the VisualBASIC utility program SETUP.EXE This program is supplied in the root or base directory as a tool for you to use in configuring jumpers on the card. It is menu-driven and provides pictures of the card on the computer monitor. You make simple keystrokes to select functions. - Page 14 OutPort Function: Writes all 16 bits of value to the hardware port at address. This function returns the value output.

Page 15: Chapter 6: Programming
Chapter 6: Programming These cards are I/O-mapped devices that are easily configured from any language and any language can easily perform digital I/O through the card's ports. This is especially true if the form of the data is byte or word wide. All references to the I/O ports would be in absolute port addressing. -

Similarly, the group 1 ports can be enabled/disabled via the control register at base address +7. The following program fragment in C language illustrates the foregoing: const BASE_ADDRESS 0x300; /*Set the mode to Mode 0, ports A and B as output, and port C as input. Since bit D7 is high, the output buffers are set to tristate condition. -
Page 18: Table 6-4: Change-Of-State Interrupt Enable Register
ENABLING/DISABLING I/O BUFFERS When using the tristate mode (Jumper in the TST position), the method to disable the I/O buffers involved writing a control word to the Control Register at Base Address +3 and Base Address +7. This control word was required to have bit D7 (the most significant bit) set. - Page 19 INTERRUPT EXAMPLES A rising edge with at least a microsecond hold time will be latched if the IEN jumper is in place and if any address decoded by the board has been read or written to. Interrupts are disabled on ‘power up’. An interrupt service routine may clear all interrupts from the board by writing any value to Base Address+1Fh.
