Page 8: Chapter 2: Installation
The software provided with this PC/104 Board is available for download from the product page on our website at http://ACCES.IO/Downloads. It is also optionally available for a nominal cost on CD (must specify when ordering product) and must be installed onto your hard disk prior to use. To do this, perform the following steps as appropriate for your operating system. -
Page 9: Installing The Hardware
Installing the Hardware Before installing the board, carefully read Chapter 3 and Chapter 4 of this manual and configure the board according to your requirements. The SETUP Program can be used to assist in configuring jumpers on the board. Be especially careful with Address Selection. If the addresses of two installed functions overlap, you will experience unpredictable computer behavior. -
Page 10: Chapter 3: Option Selection
Chapter 3: Option Selection The only selections necessary to setup on the card are the card’s base address and the differential (DIFF) / single-ended (SE) jumpers. All other features are setup via software, except IRQ’s. Interrupts are optional, and directed to levels #2 through #7, #10 through #12, and #15 by a jumper at locations labeled IRQ2 through IRQ7, IRQ10 through IRQ12, and IRQ15. -
Page 11: Chapter 4: Address Selection
Chapter 4: Address Selection The card occupies 32 bytes of I/O space. The card base address can be selected anywhere within the I/O address range 100-3E0 hex. If in doubt of where to assign the base address, refer to the table below and the FINDBASE program. - Page 12 The board’s base address is set up by JUMPERS. Those jumpers control address bits A5 through A9. (Lines A4, A3, A2, A1 and A0 are used on the board to control individual registers. How these four lines are used is described in the Programming section of this manual.) To determine how to set these JUMPERS for a desired hex-code address, refer to the SETUP program provided with the board.

Page 13: Chapter 5: Programming
Chapter 5: Programming The card is an I/O-mapped device that is easily configured from any language and any language can easily perform quadrature reads. 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. -
Page 14: Data Registers (0, 2, 4, 8, A, C, E)H
Data Registers (0, 2, 4, 8, A, C, E)h: These registers are read to retrieve the current count from the channel, and written to set the Preset Register and the Filter Clock Prescalers. To get the count from Channel 1 (Data register 0) you would first write 11h to the control register at address 1. -

Writing to the IDR (Index Control Register): Bit 0: Set high to enable index. Bit 1: Set high for a positive index polarity. Set low for a negative index polarity. Bit 2: Set low. Bits 3 & 4: Not used. Bits 5 &... -
Page 17: Writing To The Index / Interrupt Register (12H)
Writing to the Index / Interrupt Register (12h) This register is used to Preset Counter via the LCNTR input pin when a channel index occurs as described in Writing to the IOR and Writing to the IDR. Additionally it is used to generate interrupts whenever FLG1 on a channel is active as described in Writing to the IOR and Writing to the Channel Operation Register. -
