INTRODUCTION

This communications card interfaces to the CPU through a 33MHz 32bit PCI (Peripheral Component Interconnect, specification revision 2.3) local bus. While it is technically a PC/104-plus card, the ISA bus connector does not connect to any circuit.

• High Performance Octal PCI UART
• 16550 Compatible Register Set
• Up to 460Kb/s Serial Data Rate
• Global Interrupt Source Register
• Data Transfer in Byte, Word, and Double-Word
• 64-Byte Transmit and Receive FIFOs per each of eight UARTs
• Transmit and Receive FIFO Level Counters
• Programmable Transmit and Receive FIFO Trigger Level

This card is an eight channel RS-232 communication instrument. Based on the XR17D158, the card has eight enhanced 16550 UARTs, each with a set of modem signals (CTS, RTS, RI, DTR, DSR CD). A 460Kb/s is guaranteed for all channels with up to 3K Ohm 1000pF loads. All interrupts may be monitored at a 32-bit status register. Each UART has both a 64 byte transmit and a 64 byte receive FIFO.
The typical quiescent current draw from the user’s 5V supply is less than 50mA (with P1 and P2 disconnected). If every transmitter line is loaded with 3K Ohm, current draw should still be less than 150mA.
Linux drivers and sample programs are supplied with the card.
The provided Windows drivers are 100% compatible with the normal Microsoft- provided Serial Application Programming Interface. This means every program you’ve ever used with a standard serial port in Windows will also work with these ports, no problem. In addition, we provide several utility and sample programs to help you write your own code, if you’re not using something off- the-shelf.

INSTALLATION

A printed Quick-Start Guide (QSG) is packed with the board 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 PC/104 Board is on CD and must be installed onto your hard disk prior to use. To do this, perform the following steps as appropriate for your operating system. Substitute the appropriate drive letter for your CD-ROM where you see d: in the examples below.

CD Installation
The following instructions assume the CD-ROM drive is drive “D”. Please substitute the appropriate drive letter for your system as necessary.

DOS

1. Place the CD into your CD-ROM drive.
2. Type to change the active drive to the CD-ROM drive.
3. Type  to run the install program.
4. Follow the on-screen prompts to install the software for this board.

WINDOWS

1. Place the CD into your CD-ROM drive.
2. The system should automatically run the install program. If the install program does not run promptly, click START | RUN and type  , click OK or press  .
3. Follow the on-screen prompts to install the software for this board.

LINUX

1. Please refer to linux.htm on the CD-ROM for information on installing under linux.

Installing the Hardware
Before installing the board, please run setup.exe. The SETUP Program can be used to assist in configuring the two switches on the board. The setup program does not set the options on the board, these must be set manually by the user.
The PCI bus clock trace length from the CPU to the cards in the stack is tuned so that the clock edge arrives at the interface when data is valid. Since boards in the PC/104 stack are at different distances from the CPU, provision is made on the CPU board to supply four clock signals with compensating trace lengths. Two signals from other groups must be likewise selected: IDSEL and INT. When the PCI bus is being initialized, the operating system will enable each card with a hard-wired select line and read it’s configuration registers. An address is assigned, space in the memory map and I/O map is reserved, etc. Similarly, the CPU’s interrupt controller resources (INTA, INTB, INTC, INTD) will be distributed among the cards in the stack. A set of four-to-one multiplexers and two slide switches are used to select which PCI clock, IDSEL and INT lines are routed to the card’s PCI bus interface.
Only four PCI boards are allowed in a PC/104-Plus stack, each board must get a specific set of signals. These signals are selected with two slide switches, labeled SEL-1 and SEL-2, which form a binary value to control the mux (SEL-1 is the least significant bit and SEL-2 is the most significant bit). If this card is furthest from the CPU, slide both switches to the OFF STATE. This will select the signal with the longest trace on the CPU board (signal group 3). If this card is closest to the CPU, slide both switches to the ON STATE. This will select the signal with the shortest trace on the CPU board (signal group 0). Place the SEL-1 switch to ON and SEL-2 to OFF to select signal group 2, place the SEL-1 switch to OFF and SEL-2 to OFF to select signal group 1.

To Install the Card

1. Install jumpers for selected options and base address according to your application requirements, as mentioned above.
2. Remove power from the PC/104 stack.
3. Assemble standoff hardware for stacking and securing the boards.
4. Carefully plug the board onto the PC/104 connector on the CPU or onto the stack, ensuring proper alignment of the pins before completely seating the connectors together.
5. Install I/O cables onto the board’s I/O connectors and proceed to secure the stack together or repeat steps 3-5 until all boards are installed using the selected mounting hardware.
6. Check that all connections in your PC/104 stack are correct and secure then power up the system.
7. Run one of the provided sample programs appropriate for your operating system that was installed from the CD to test and validate your installation.

Figure 2-1: PC/104 Key Information
Our setup program will lead the user through the process of setting the options on the card. The setup program does not set the options on the card. These must be set by jumpers on the card.

To install the card:

1. Turn off the computer power.
2. Position the slide switches to select the clock, IDSEL, and interrupt signal group.
3. Install the card in a PC/104-Plus stack.
4. Install I/O cables at P1 and P2.
5. Inspect for proper fit of the card and cable and then tighten the screws.

OPTION SELECTION

Most PCI bus signals are common to all four cards in the PCI stack. However, there are four unique signal groups, one for each card. The slide switches select which signal group goes to each card. The card in the stack closest to the CPU board must get signal group 0.

ADDRESS SELECTION

The system BIOS or operating system will assign the address. The card occupies 4K bytes of I/O space. The 32 bit interrupt status register is at base address

• 80h.
  PCI architecture is Plug-and-Play. This means that the BIOS or Operating System determines the resources assigned to PCI cards rather than you selecting those resources with switches or jumpers. As a result, you cannot set or change the card’s base address. You can only determine what the system has assigned.
  To determine the base address that has been assigned, run the PCIFind.EXE, or PCINT utility program provided. This utility will display a list of all of the cards detected on the PCI bus, the addresses assigned to each function on each of the cards, and the respective IRQs (if any) allotted.
  Alternatively, some operating systems (Windows 95/98/2000) can be queried to determine which resources were assigned. In these operating systems, you can use either PCIFind (DOS), PCINT (Windows95/98/NT), or the Device Manager utility from the System Applet of the control panel. The card is installed in the Data Acquisition class of the Device Manager list. Selecting the card, clicking Properties, and then selecting the Resources Tab will display a list of the resources allocated to the card.
  The PCI bus supports 64K of I/O space. Your card’s addresses may be located anywhere in the 0000 to FFFF hex range.
  PCIFind uses the Vendor ID and Device ID to search for your card, then reads the base address and IRQ.
  If you want to determine the base address and IRQ yourself, use the following information.
  The Vendor ID for the card is 494F. (ASCII for “IO”)
  The Device ID for the card is 10A8.
