PCI configuration
The PCI cards are equipped with a plug and play PCI controller,
it can request base addresses and interrupts in accordance with the PCI
standard. The system BIOS will install the system resource based on the
PCI cards’ configuration registers and system parameters (which are set
by system BIOS). Interrupt assignment and memory usage (I/O port
locations) of the PCI cards can be assigned by system BIOS only. These
system resource assignments are done on a board-by-board basis. It is
not suggested to assign the system resource by any other methods.
PCI slot selection
The PCI card can be inserted to any PCI slot without any configuration for
system resource. Please note that the PCI system board and slot must
provide bus -mastering capability to operate this board properly.
PCI Installation Procedures
1. Turn off your computer
2. Turn off all accessories (printer, modem, monitor, etc.) connected to
your computer.
3. Remove the cover from your computer.
4. Set up jumpers on the PCI card.
5. Select a 32-bit PCI slot. PCI slots are shorter than ISA or EISA slots, and

2.7 Jumpers Description
The 48H/96H DIO cards are ‘plug-and-play’, thus it is not necessary to setup
the card configurations to fit the computer system. However, to fit users’
versatile operation environment, there are still a few jumpers to set the
power-on status of ports and the usage of the +12V output pins.
2.7.1 Power on Status of Ports
For every port on the PCIDIO 48H/96H cards, the power-on status is set as input,
therefore, the voltage could be pulled high, pulled low, or floating. It is
dependent on the jumper setting. Table 2.1 lists the reference number of
the jumpers and the corresponding port names.
Jumper Port Name Remarks
JA1 P1A (Port A of CN1)
JB1 P1B (Port B of CN1)
JC1 P1C (Port C of CN1)
JA2 P2A (Port A of CN2) for PCIDIO 48H/96H
JB2 P2B (Port B of CN2) for PCIDIO 48H/96H

JB3 P3B (Port B of CN3) for PCIDIO 96H
J C3 P3C (Port C of CN3) for PCIDIO 96H
JA4 P4A (Port A of CN4) for PCIDIO 96H

The physical meaning of all the jumpers are identical. The power on status
of each port can be set independently. The default is to pull all signals high.
The following diagram uses JA1 as an example to show the possible
configurations.

Registers Format
Detailed descriptions of the register's format are specified in this
chapter. This information is quite useful for the programmers who wish to
handle the card through low-level programming. However, we suggest
users understand more about the PCI interface before beginning any low-level
programming. In addition, the contents of this chapter can help users
understand how to use a software driver to manipulate this card.
3.1 PCI PnP Registers
This PCI card functions as a 32-bit PCI target device to any master on the
PCI bus. There are three types of registers: PCI Configuration Registers
(PCR), Local Configuration Registers (LCR) and PCIDAC 082 registers.
The PCR, which is compliant with PCI-bus specifications, is initialized
and controlled by the plug & play (PnP) PCI BIOS. User's can study the PCI
BIOS specification to understand the operation of the PCR.
The PCI bus controller PCI-9050 is provided by PLX technology Inc.
(www.plxtech.com). For more detailed information of LCR, please visit PLX
technology’s web site to download relative information. It is not necessary
for users to understand the details of the LCR if you use the software library.
The PCI PnP BIOS assigns the base address of the LCR. The assigned
address is located at offset 14h of PCR.
The PCIDAC 0812 registers are shown in the next section. The base address,
which is also assigned by the PCI PnP BIOS, is located at offset 18h of
PCR. Therefore, users can read the 18h of PCR to know the base address
by using the BIOS function call.
Please do not try to modify the base address and interrupt which assigned
by the PCI PnP BIOS, it may cause a resource conflict in your system.
20 • Registers Format
3.2 I/O Address Map
All the 48H registers are 8 bits. The users can access these registers
only by 8 bits I/O instructions. The following ta ble shows the registers map,
including descriptions and their offset addresses relative to the base
address. Please refer to the chapter 4 for more detailed operation of every
registers.

Operation Theorem
4.1 Digital I/O Ports
4.1.1 Introduction
The 48H/96H products can emulate one/two/four mode 0 configuration of
8255 programmable peripheral interface (PPI) chips. There are 24 DIO
signals for every PPI.
4.1.2 8255 Mode 0
The basic functions of 8255 mode 0 are:
l Two 8-bit I/O ports−−port A (PA) and port B (PB)
l Two nibble-wide (4-bit) ports C−−PC upper and PC lower
l Each port can be used as either input or output
l Outputs are latched whereas inputs are buffered
l 16 different input/output configurations are available
4.1.3 Special Function of the DIO Signals
Two I/O signals (PC0 and PC3) of CN1 and CN2 can be used to generate
hardware interrupt. Refer to section 4.3 for details about the interrupt
control. In addition, the P1C4 signals can be used as input signal of event
counter.
22 • Operation Theorem
4.1.4 Digital I/O Port Programming
Users can write the digital output value to or read back the digital signal
level from the PPI ports by using the software library. Here we define the
port name in Table 4.1. These port names are used both in software library
and all through this manual. The programming for PCIDIO 24H/48H
and PCIDIO 96H are fully compatible.

(* power on default configuration)
4.1.6 Power on Configuration
The default configuration after power on, hardware reset or software reset
sets all ports as input ports, and therefore, users don’t have to worry about
damaging the external devices when system is power on. In addition, the
default signal level can be pulled high or pulled low by setting the jumpers.
Refer to section 2.7 for setting the power on status of the DI O ports.
4.1.7 Note for Output Data
Be careful of the initial condition of digital output signals. If users set the
control word as output port after power on, the previous uncertain output
value will be put on the output pins immediately. Therefore, BE SURE TO
WRITE A SAFE VALUE TO THE PORTS BEFORE CONFIGURING THEM AS
OUTPUT PORTS.

4.2 Timer/Counter Operation
4.2.1 Introduction
One 8254 programmable timer/counter chip is installed in 48H/96H series.
There are three counters in one 8254 chip and 6 possible operation modes
for each counter. The block diagram of the timer/counter system is shown
in Figure 4.2.

The timer #1 and timer #2 of the 8254 chip are cascaded as a 32-bit
programmable timer. In software library, the timer #1 and #2 are always
set as mode 2 (rate generator).

In software library, the counter #0 is used as an event counter, that is,
interrupt on terminal count of 8254 mode 0 . Please refer to chapter 5 for
programming the timer/counter functions.
4.2.2 General Purpose Timer/Counter
The counter 0 is a general purpose timer/counter for users applications. It
can be used as an event counter, or used for measuring frequency, or other
functions. The following Mode are provided by the 82C54 chip.
l Mode 0: Interrupt on Terminal Count
l Mode 1: Programmable One-Shot.
l Mode 2: Rate Generator.
l Mode 3: Square Wave Rate Generator.
l Mode 4: Software Triggered Strobe.
l Mode 5: Hardware Triggered Strobe.
Operation Theorem • 25
The 8254 timer/ counter IC occupies 4 I/O address. Users can refer to
Tundra's or Intel's data sheet for a full description of the 8254 features. You
can download the 8254 data sheet from the following web site:
http://support.intel.com/support/controllers/peripheral/231164.htm
or
http://www.tundra.com (for Tundra’s 82C54 datasheet.)
4.2.2 Cascaded 32 Bits Timer
The input clock frequency of the cascaded timers is 2MHz. The output of the
timer is send to the interrupt circuit (refer to section 4.3). Therefore, the
maximum and minimum watchdog timer interrupt frequency is
(2MHz)/(2*2)=500KHz and (2MHz)/(65535*65535)= 0.000466Hz
respectively.
4.2.3 Event Counter and Edge Control
The counter #0 of the 8254 chip can be used as an event counter. The
input of counter #0 is PC4 of CN1 (P1C4). The counter clock trigger
direction (H to L or L to H) is programmable. The gate control is always
enabled. The output is send to interrupt system which named as event IRQ.
If counter #0 is set as 8254 mode 0, the event counter IRQ will generate
when the counter value is counting down to zero.
4.3 Interrupt Multiplexing
4.3.1 Architecture
The 48H/96H series products have a powerful and flexible interrupt
multiplexing circuit which is suitable for many applications. The board
could accept Dual Interrupts. The dual interrupt means that the hardware
can generate two interrupt request signals at the same time and the
software can service these two request signals by ISR. Note that th e dual
interrupts do not mean that the card occupies two IRQ levels.
The two interrupt request signals (INT1 and INT2) comes from digital input
signals or the timer/counter output. An interrupt source multiplexer (MUX) is
used to select the IRQ sources. Fig 4.3 shows the interrupt system.

4.3.2 IRQ Level Setting
There is only one IRQ level requested by this card, although it is a dual
interrupt system. The motherboard circuits will transfer INTA# to one of the
PC IRQ levels. The IRQ level is set by the PCI plug and play BIOS and
saved in the PCI controller. Users can get the IRQ level setting by software
library.

4.3.3 Note for Dual Interrupts
The PCI controller of PCIDIO 24H/48H/96H can receive two hardware IRQ
sources. However, a PCI controller can generate only one IRQ to PCI bus,
the two IRQ sources must be distinguished by the ISR of the application
software if the two IRQs are both used.
The application software can use the “_dioxxh_Get_Irq_Status” function to
distinguish which interrupt is inserted. After an ISR is completed, users must
check if another IRQ is also asserted, then clear current IRQ to allow the
next IRQ coming in.
The two IRQs are named as INT1 and INT2. In PCIDIO 24H/48H/96H, INT1
comes from P1C0, P1C3 or the event counter interrupt. INT2 comes from
P2C0, P2C3 or the timer interrupt. However in PCIDIO 24H, INT2 only comes
from timer interrupt. The sources of INT1 and INT2 is selectable by the
Interrupt Source Control (ISC) Register.
Operation Theorem • 27
4.3.4 Interrupt Source Control
In ISC register (offset 0x20), there are four bits to control the IRQ sources of
INT1 and INT2.
If the application need only one IRQ, you can disable one of the IRQ
sources by software. If your application doesn't need any IRQ source, you
can disable both interrupts. However, the PCI BIOS still assigns an IRQ level
to the PCI card and occupies the PC resource if you only disable the IRQ
sources without changing the i nitial condition of the PCI controller.
It is not recommended to change the initial condition of the PCI card through
a user's own application software. If users want to disable the IRQ level,
they can use the utility "util DIO 48H.exe" or "util DIO 96H.exe to change
the power on an interrupt setting.
The table 4.3 shows the register format of the ISC (address offset 0x20).
This register is write only. The 4 LSBs are used to control the source of
INT1 and INT2.
INT1 D3 D2 D1 D0 IRQ Sources IRQ Trigger Condition
Disable X X 0 0 INT1 disable --
Mode 1 X X 0 1 ~P1C0 falling edge of P1C0
Mode 2 X X 1 0 P1C0 OR ~P1C3 (see following)
Mode 3 X X 1 1 Event Counter Counter count down to 0
INT2 D3 D2 D1 D0 IRQ Sources IRQ Trigger Condition
Disable 0 0 X X INT2 disable --
Mode 1 0 1 X X ~P2C0 falling edge of P2C0(*)
Mode 2 1 0 X X P2C0 OR ~P2C3 (see following) (*)
Mode 3 1 1 X X Timer Output Timer count down to 0
Table 4.3 ISC register format
(*) Note: Not available on PCIDIO 24H.
Then the IRQ sources is set as “P1C0 OR ~P1C3”, the IRQ trigger
conditions are summarized in table 4.4.
P1/2C0 P1/2C3 IRQ Trigger Condition
High X PC0=‘H’ disable all IRQ
X Low PC3=‘L’ disable all IRQ
Low 1->0 PC3 falling edge trigger when PC0=L
0->1 High PC0 rising edge trigger when PC3=H
Table 4.4 IRQ Trigger conditions
Because the P1/P2C0 and P1/P2C3 are external signals, the users can
utilize the combination of the four signals to generate a proper IRQ.
28 • Operation Theorem
4.4 12V and 5V Power Supply
The OPTO-22 compatible connectors provide external devices the +12 volts
and +5 volts power supply. To avoid short or overload of the power supply,
resetable fuses are added on all the output power. Refer to Figure 2.5.
The maximum current for 5 volts on every connector is 0.5 A. If the load
current is larger than 0.5 A, the resistance of resetable fuse will increase
because of the rising temperature. The rising resistance will cause the
power supply drop and reduce current. If the overload or short condition is
removed, the fuse will get to normal condition. It is not necessary to repair
or re-install the fuse.
The maximum current of 12 volts for all the four connectors is also 0.5 A.
The action of the fuse is the same as which used for +5V power. The
limitation is more restrictive than 5V power supply because the PCI bus can
not provide large current.

C/C++ Libraries
This chapter describes the software library for operating these card. Only
the functions in DOS library and Windows 95 DLL are described. Please
refer to the PCI DASK function reference manual, which is included with
the CD, for the descriptions of the Windows 98/NT/2000/XP DLL functions.
The functions of PCIDIO 48H can also be applied to PCIDIO 24H.
Therefore, in the following section, there are no special functions for the
PCIDIO 24H. The software driver of PCIDIO 24H is fully compatible
with that of PCIDIO 48H. In the following sections, each function call that
has a name associated with “DIO48H" can be applied to PCIDIO 24H directly.
The function prototypes and some useful constants are defined in the
header files LIB directory (DOS) and INCLUDE directory (Windows 95). For
Windows 95 DLL, the developing environment can be Visual Basic 4.0 or
above, Visual C/C++ 4.0 or above, Borland C++ 5.0 or above, Borland
Delphi 2.x (32-bit) or above, or any Windows programming language that
allows calls to a DLL. It provides the C/C++, VB, and Delphi include files.
5.1 Libraries Installation
Please refer to the “Software Installation Guide ” for the detail information
about how to install the software libraries for DOS, or Windows 95 DLL, or
PCI DASK for Windows 98/NT/2000/XP.
The device drivers and DLL functions of Windows 98/NT/2000/XP are included
with PCI DASK. Please refer the PCI DASK user’s guide and function

5.2 Programming Guide
5.2.1 Naming Convention
The functions of the PCIDAQ PCI cards' software driver use full-names to
represent a function's real meaning. The naming convention rules are:
In DOS Environment:
_{hardware_model}_{action_name}. e.g.
All functions in the PCIDIO 48H driver are used by the board as
{hardware_model}. But they can be used by PCIDIO 48H and PCIDIO 24H.
In order to recognize the difference between the DOS library and Windows 95
library, a capital "W" is put on the head of each function name of the
Windows 95 DLL driver. e.g.
W_DIO48H_Initial()
_DIO48H_Initial()
.
.
5.2.2 Data Types
We defined some data type in DIO48H.h (DOS) and Acl_pci.h (Windows
95). These data types are used by the PCIDAQ Card library. We suggest you
to use these data types in your application programs. The following table
shows the data type names and their range.

Product Service
Diagnosis and Debug
CyberResearch, Inc. maintains technical support lines staffed by experienced
Applications Engineers and Technicians. There is no charge to call and we will
return your call promptly if it is received while our lines are busy. Most problems
encountered with data acquisition products can be solved over the phone. Signal
connections and programming are the two most common sources of difficulty.
CyberResearch support personnel can help you solve these problems, especially if
you are prepared for the call.
To ensure your call’s overall success and expediency:
1) Have the phone close to the PC so you can conveniently and quickly take action
that the Applications Engineer might suggest.
2) Be prepared to open your PC, remove boards, report back-switch or jumper
settings, and possibly change settings before reinstalling the modules.
3) Have a volt meter handy to take measurements of the signals you are trying to
measure as well as the signals on the board, module, or power supply.
4) Isolate problem areas that are not working as you expected.
5) Have the source code to the program you are having trouble with available so
that preceding and prerequisite modes can be referenced and discussed.
6) Have the manual at hand. Also have the product’s utility disks and any other
relevant disks nearby so programs and version numbers can be checked.
Preparation will facilitate the diagnosis procedure, save you time, and avoid repeated
calls. Here are a few preliminary actions you can take before you call which may
solve some of the more common problems:
1) Check the PC-bus power and any power supply signals.
2) Check the voltage level of the signal between SIGNAL HIGH and SIGNAL LOW,
or SIGNAL+ and SIGNAL– . It CANNOT exceed the full scale range of the board.
3) Check the other boards in your PC or modules on the network for address and
interrupt conflicts.
4) Refer to the example programs as a baseline for comparing code.
