Page 5: Chapter 1: Functional Description
Chapter 1: Functional Description FEATURES • 48 Bits of Digital Input/Output. • Interrupt Generation on Input or under program control (Model “48JP”) • Change-of-state Interrupt Software Enabled in Six 8-Input Ports.(Model “48JPS”) • All 48 I/O Lines Buffered on the Board. •... - Page 6 jumper is properly placed on the card the tristate buffers may be enabled/disabled under program control. (See the Option Selection section to follow.) I/O wiring connections are via a 68-pin high-density connector with screw locks. If needed for external circuits, +5 VDC power is available at pins 67 and 68. There is a resettable 0.5A polyfuse onboard that feeds both pins.

Page 7: 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. The software provided with this card is on CD and must be installed onto your hard disk prior to use. - Page 8 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 9: Chapter 3: Option Selection
Chapter 3: Option Selection Refer to the setup programs on the CD provided with the card. Also, refer to the block diagram on the previous page and the option selection map on this 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 10: 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 11: Chapter 5: Software
Chapter 5: Software The following paragraphs describe the setup program and, 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 12 OutPort Function: Writes all 16 bits of value to the hardware port at address. This function returns the value output. Declaration: function OutPort(byval address as integer, byval value as integer) as integer Peek Function: Reads a byte from main memory (DRAM). Declaration: function Peek(byval segment...

Page 13: 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. - Page 14 Assignment Code Port C Lo (C0-C3) 1=Input, 0=Output Port B 1=Input, 0=Output Mode Select 1=Mode 1, 0=Mode 0 Port C Hi (C4-C7) 1=Input, 0=Output Port A 1=Input, 0=Output D5,D6 Mode Select 00=Mode 0, 01=Mode 1, 1X=Mode 2 Mode Set Flag 1=Active Table 6-2: Control Register Bit Assignment Note:...
- Page 15 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 17 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+Fh.
