The following safety precautions should be observed before using this product and any associated instrumentation.
Although some instruments and accessories would normally be used with non-hazardous voltages, there are situations
where hazardous conditions may be present.

This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety
precautions required to avoid possible injury. Read and follow all installation, operation, and maintenance information
carefully before using the product. Refer to the manual for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product may be impaired.

The types of product users are:

Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that

the equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately
trained.

Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use

of the instrument. They must be protected from electric shock and contact with hazardous live circuits.

Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting

the line voltage or replacing consumable materials. Maintenance procedures are described in the manual. The proce­dures explicitly state if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel are trained to work on live circuits, and perform safe installations and repairs of products. Only

properly trained service personnel may perform installation and service procedures.

Keithley products are designed for use with electrical signals that are rated Installation Category I and Installation
Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most mea­surement, control, and data I/O signals are Installation Category I and must not be directly connected to mains voltage
or to voltage sources with high transient over-voltages. Installation Category II connections require protection for high
transient over-voltages often associated with local AC mains connections. Assume all measurement, control, and data
I/O connections are for connection to Category I sources unless otherwise marked or described in the Manual.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or
test fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels
greater than 30V RMS, 42.4V peak, or 60VDC are present.

age is present in any unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that
operators are prevented access and/or insulated from every connection point. In some cases, connections must be ex­posed to potential human contact. Product operators in these circumstances must be trained to protect themselves from
the risk of electric shock. If the circuit is capable of operating at or above 1000 volts,

may be exposed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance
limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards,
install protective devices to limit fault current and voltage to the card.

Before operating an instrument, make sure the line cord is connected to a properly grounded power receptacle. Inspect
the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.

afety Precautions

A good safety practice is to expect that hazardous volt-

no conductive part of the circuit

5/02

When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main
input power disconnect device must be provided, in close proximity to the equipment and within easy reach of the
operator.

For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the cir­cuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting
or disconnecting cables or jumpers, installing or removing switching cards, or making internal changes, such as in­stalling or removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth)
ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the
voltage being measured.

The instrument and accessories must be used in accordance with its specifications and operating instructions or the
safety of the equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and op­erating information, and as shown on the instrument or test fixture panels, or switching card.

When fuses are used in a product, replace with same type and rating for continued protection against fire hazard.

Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground con­nections.

If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation re­quires the use of a lid interlock.

If or is present, connect it to safety earth ground using the wire recommended in the user documentation.

!

The symbol on an instrument indicates that the user should refer to the operating instructions located in the manual.

The symbol on an instrument shows that it can source or measure 1000 volts or more, including the combined
effect of normal and common mode voltages. Use standard safety precautions to avoid personal contact with these
voltages.

The

the warranty.

Instrumentation and accessories shall not be connected to humans.

Before performing any maintenance, disconnect the line cord and all test cables.

To maintain protection from electric shock and fire, replacement components in mains circuits, including the power
transformer, test leads, and input jacks, must be purchased from Keithley Instruments. Standard fuses, with applicable
national safety approvals, may be used if the rating and type are the same. Other components that are not safety related
may be purchased from other suppliers as long as they are equivalent to the original component. (Note that selected parts
should be purchased only through Keithley Instruments to maintain accuracy and functionality of the product.) If you
are unsure about the applicability of a replacement component, call a Keithley Instruments office for information.

To clean an instrument, use a damp cloth or mild, water based cleaner. Clean the exterior of the instrument only. Do
not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist
of a circuit board with no case or chassis (e.g., data acquisition board for installation into a computer) should never
require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected,
the board should be returned to the factory for proper cleaning/servicing.

do not use these boards with the covers

In addition, disconnect all cables when servicing these boards.

1-2 Overview

Supporting Software

DriverLINX software is supplied by Keithley with the PIO-32 Series
board. DriverLINX provides convenient interfaces to configure and set
I/O bits without register-level programming.

Most importantly, however, DriverLINX supports those programmers
who wish to create custom applications using Visual C/C++, Visual Basic,
or Delphi. DriverLINX accomplishes foreground and background tasks to
perform data acquisition. The software includes memory and data buffer
management, event triggering, extensive error checking, and context
sensitive online help.

More specifically, DriverLINX provides application developers a
standardized interface to over 100 services for creating foreground and
background tasks for the following:

Analog input and output

●

Digital input and output

●

●

Time and frequency measurement

Event counting

●

●

Pulse output

Period measurement

●

In addition to basic I/O support, DriverLINX also provides:

●

Built-in capabilities to handle memory and data buffer management

A selection of starting and stopping trigger events, including

●

pre-triggering, mid-point triggering and post-triggering protocols

●

Extensive error checking

●

Context-sensitive on-line help system

1-3

Accessories

DriverLINX is essentially hardware independent, because its portable
APIs work across various operating systems. This capability eliminates
unnecessary programming when changing operating system platforms.

The optional accessories for the PIO-32 Series boards include screw
terminal panels (STPs) and cables (C-3200/C-32NN) that convert from
the ribbon headers on the board to the 37-D male cable connectors. The
C-3200 cables are 30 inches long; longer cables are available, C-32NN,
where NN is the number of feet added to the standard cable.

You can use STPs and cables to connect applications to the PIO-32 Series
boards. An STP-37/FC accessory is available that combines a 37-D
female receptacle, which directly mates to the 37-D male connector on
the optional C-3200 cable for the PIO-32 Series boards, and 37 screw
terminals in a protective case for desktop use.

Warning:

other STPs at voltages above 30V RMS, 42.4V peak, or 60VDC. These
accessories are rated for 30V RMS, 42.4V peak, or 60VDC maximum.
Use at higher voltages may result in shock hazard.

Functional Description

This section describes the general layout of the PIO-32 Series boards and
provides schematics of the typical input and output circuits.

The PIO-32 Series boards are channel-to-channel isolated and handle
digital voltages in a broader range than standard TTL levels. Optional
accessories for the board include screw terminal panels (STPs) and the
C-3200 cables. The C-3200 cables are 30-inches long; they let you route
the signals from 40-pin headers on the board through a slot in the rear
panel bracket to 37-D male connectors. You connect the 37-D connectors
to the optional STPs.

Figure 2-1 shows the general layout of PIO-32 Series boards. Note the
ribbon headers, labeled J1 and/or J2, on your board; these ribbon headers
provide 16 digital input or output channels each. The orientation of the
headers differs among the boards, as shown in Figure 2-1.

Setup and Installation

Warning: The procedures in this section are intended for qualified

service personnel. Do not perform these procedures unless you are
qualified to do so.

This section describes the following:

● Inventorying installation resources.

● Installing the DriverLINX software needed to operate your PIO-32

board.

● Configuring the installation in software.

● Unpacking and inspecting the board, setting the base address of the

board, and then installing the board in your computer.

● Checking the installation.

If you encounter any problems with the board after installation, refer to
Section 6 for troubleshooting information.

3-1

Note: Install the DriverLINX software before installing the PIO-32

board. Otherwise, the device drivers will be more difficult to install.

Inventorying Required Installation Resources

Before installing DriverLINX and the board, do the following:

1. Inventory your PIO-32 board’s configuration settings.

2. Determine the resources your PIO-32 board requires.

3. Inventory your computer’s resources already allocated to other
installed devices.

4. Determine whether your computer has sufficient resources for your
PIO-32 board.

5. Determine whether your PIO-32 board can use your computer’s free
resources.

Note: The DriverLINX Installation and Configuration Guide, Section 1,

amplifies the inventory process in checklist items 1-5. (Ignore the rest of
the checklist items for now.) To display this manual from your
DriverLINX PIO Series CD-ROM, open the Windows Explorer, then
double click on X:\Drvlinx4\Docs\Instconf.pdf, where X = the letter of
the CD-ROM drive. Acrobat Reader must already be installed on the other
system. If necessary, you can first install Acrobat Reader directly from the
CD-ROM by double clicking X:\Acrobat\setup.exe.

3-2 Setup and Installation

Installing DriverLINX Software and Documentation

Note: Even if DriverLINX versions other than the PIO Series version are

already installed on your system, you must also install the PIO Series
DriverLINX version. In the process, some DriverLINX capabilities shared
by all boards may be upgraded (test utilities, for example).

This section discusses installation of drivers, interfaces, and
documentation. The component installation options provided by the
DriverLINX setup program are as follows:

● Install Drivers — This required component installs only the files you

need for configuring your hardware and running third-party
data-acquisition applications that require DriverLINX.

● Install Interfaces — This optional component installs the files and

example programs that you will need to develop custom applications
for DriverLINX using C/C++, Visual Basic, and Delphi.

● Install Documentation — This optional component installs

electronic documentation for DriverLINX that you can read, search,
and print using the Adobe Acrobat Reader.

● Install Acrobat — This optional component installs the Adobe

Acrobat Reader for the DriverLINX electronic documentation.

Install the DriverLINX software and board as follows:

1. Place the DriverLINX PIO Series CD-ROM in your drive and wait a
few seconds. On most systems, setup starts automatically. If not, run
the setup.exe file, found in the root directory of the CD-ROM.

A DriverLINX Browser Introduction screen appears. Thereafter, the
DriverLINX CD Navigator screen appears automatically after
waiting a few seconds or after clicking Next.

3-3

Note: On the DriverLINX CD Navigator and other DriverLINX Browser

screens, place the cursor over a menu item to see an explanation. A star
next to a menu item means that it was selected previously.

Before continuing with this installation, Keithley suggests clicking Read
Me First on the DriverLINX CD Navigator and reviewing the brief
information that appears.

2. On the DriverLINX CD Navigator screen, click Install
DriverLINX. An Install These DriverLINX Components screen
appears.

3. Click Install Drivers, and then follow the series of on-screen
instructions. When done, the Install These DriverLINX Components
screen reappears.

4. If you do not plan to develop custom application software for your
PIO-32 Series board, then skip to Step 5. If you do plan to develop
custom application software, you must install DriverLINX
interfaces before writing the software. Install them now by clicking
Install Interfaces and following the series of on-screen
instructions. When done, the Install These DriverLINX Components
screen reappears.

5. Click Install Documentation and follow the series of on-screen
instructions. This step installs the manuals. When done, the Install
These DriverLINX Components screen reappears.

6. If Acrobat Reader is not already installed on your system, install it
now. You need Acrobat Reader to read the manuals, a section of
which you must access in step 9. Click on Install Acrobat and
follow the series of on-screen instructions. When done, the Install
These DriverLINX Components screen reappears.

7. Click Exit. Then, on the screen that appears saying “Thank you for
using DriverLINX,” click Done. The System Settings Changed
dialog box appears.

3-4 Setup and Installation

8. On the System Settings Changed dialog box, click No. (The system
will be rebooted and configured later under “Configuring Your
Installation.”) The screen returns to the Windows desktop.

9. Print out one section of a DriverLINX manual that you will briefly
review later during system configuration. Proceed as follows:

a. In the Start menu under Programs

→ DriverLINX, click

On-line Manuals. A menu document appears

b. In the menu document, scroll until you find the major category

Configuration.

c. Under Configuration click Hardware References. A list of

documents appears.

d. In the list of documents, click Keithley PIO Series. Acrobat

Reader opens and the manual entitled Using DriverLINX with
Your Hardware—Keithley PIO Series appears.

e. Print the following section from the Using DriverLINX with

Your Hardware—Keithley PIO Series manual: “Configuring the
PIO Series.”

Note: If your data acquisition system is not connected to a printer, you

can display and print the Using DriverLINX with Your Hardware—
Keithley PIO Series manual sections from another system, directly from

the CD-ROM (without installing anything). To display the manual, open
the Windows Explorer, then double click on
X:\Drvlinx4\Docs\Notes\kmbpio.pdf, where X = the letter of the
CD-ROM drive. Acrobat Reader must already be installed on the other
system. If necessary, you can first install Acrobat Reader directly from the
CD-ROM by double clicking X:\Acrobat\setup.exe.

10. Continue with the next section, “Configuring Your Installation.”

3-5

Configuring Y our Installation

1. Locate and briefly review the manual section, “Configuring the PIO
Series,” that you printed earlier during step 9 of “Installing
DriverLINX Software and Documentation.” Reviewing this section
will help prepare you to input information and select options when
configuring your installation.

Note: Be sure to note and follow all configuration differences between

installations for Windows NT and Windows 95/98.

2. Reboot your computer. The DriverLINX Plug and Play Wizard
appears on your screen automatically at the end of the boot cycle.

Note: If you do not run the DriverLINX Plug and Play Wizard now, it

will not reappear during the current computer session, although it may
appear after a subsequent reboot. If you wish to configure your board
sometime later, you can start the Plug and Play Wizard manually from a
batch file. In the Windows Explorer, double click
X:\Drvlinx4\Help\kmbpio.bat, where X is the letter of the drive on which
DriverLINX is installed.

3. On the Plug and Play Wizard, click Wizard and follow the series of
on-screen instructions that appear. The wizard will first lead you
through the steps of installing your hardware—from a software
viewpoint—and configuring it.

Note: If your operating system is Windows NT, use Windows NT

Diagnostics to find the free resources that the Plug and Play Wizard asks
you to assign. However, if your board requires an interrupt, to reliably
find a free ISA interrupt you may need to: 1) configure your computer as
having a non-Plug and Play operating system, using BIOS setup, and then

2) individually assign the interrupt to the ISA bus.

4. Continue with the next section, “Preparing and Installing Your
Board.”

3-6 Setup and Installation

Preparing and Installing Your Board

Caution: Ensure that the computer is turned OFF before installing or

removing a board. Installing or removing a board while power is ON can
damage your computer, the board, or both.

Handle the board in a static-controlled workstation; wear a grounded
wrist strap. Discharge static voltage differences between the wrapped
board and the handling environment before removing the board from its
protective wrapper. Failure to discharge static electricity before and
during handling may damage semiconductor circuits on the board.

Handle the board using the mounting bracket. Do not touch the circuit
traces or connector contacts when handling the board.

Unpacking the Board

To prevent any damage to your PIO-32 Series board, perform the
following steps when unpacking the board:

1. Remove the wrapped PIO-32 Series board from its outer shipping
carton.

2. Making sure your computer is turned OFF but grounded, hold the
wrapped board in one hand while placing your other hand firmly on
the metal portion of the computer chassis; this discharges any static
electricity.

3. Carefully remove the board from its anti-static wrapping material.
You may store the wrapping material for future use.

4. Inspect the board for signs of damage. If any damage is apparent,
arrange to return the board to the factory; refer to Section 6 for more
information.

5. Check the remaining contents of your package against the packing
list to ensure that your order is complete. Immediately report any
missing items to the factory.

3-7

6. Once you have determined that the board is acceptable, set the base
address. The next section explains how to set the base address.

Setting the Base Address

Note: Before setting the base address switches, check the different

requirements for Windows 95/98 and Windows NT. Refer to “Configuring
the PIO Series” in Using DriverLINX with Your Hardware—Keithley PIO
Series manual, which you printed in step 9 of “Installing the DriverLINX
Software.”

The base address is the only item you need to set on the PIO-32 Series
boards. The PIO-32 Series boards normally use a block of eight I/O
addresses. The factory default base address is 300h. If 300h was assigned
to the board when you ran the DriverLINX Plug and Play Wizard, you do
not need to set the address switch. Otherwise, reconfigure the base
address switch (labeled BASE ADDRESS on the board) to conform to the
base address assigned when you ran the Wizard.

The base address switch block contains eight switches, labeled 1 through

8. Switch 1 corresponds to the most significant bit (MSB) of the base
address (A9); switch 7 corresponds to the least significant bit (LSB) of the
base address (A3). Switch 8 is reserved.

You place a switch in the ON position (logic 0) by sliding the switch
toward the top (numbered side) of the switch block. You place a switch in
the OFF position (logic 1) by sliding the switch toward the bottom
(unnumbered side) of the switch block. Figure 3-1 illustrates the setting
for a base address of 300h; switches 1 and 2 are in the OFF position and
switches 3, 4, 5, 6, 7, and 8 are in the ON position (A9 and A8 are logic 1,
A7 through A3 are logic 0).

Before installing the PIO-32 Series board in the host computer, ensure
that the base address switches are set appropriately.

Warning: Do not connect voltages greater than 30V RMS, 42.4V peak,

or 60VDC to any input or output on this board.

Live voltages can still be present on the board even when the computer is
turned off. To protect you and the circuit, Keithley provides covers with
the PIO-32 Series boards. Though you can remove the covers to service
the PIO-32 Series boards, do not use these boards with the covers
removed! In addition, disconnect all cables when servicing these boards.

Caution: Installing or removing a board with the power ON can cause

damage to your board and/or computer.

3-9

To install the board, perform the following steps:

1. Turn power to the computer and all attached equipment OFF.

2. Remove the computer chassis cover.

3. Select an available slot appropriate to the length of the board.

4. Loosen and remove the screw at the top of the blank adapter plate,
and then slide the plate up and out to remove.

5. If you are installing your own cables or the optional
C-3200/C-32NN ribbon cables, decide how to run the cables. Note
that the strain relief on the C-3200/C-32NN 40-pin connector may
need to be removed for clearance or to allow the cable to run in the
correct direction. Decide on the folds and orientation of the cables
but do not install them yet.

6. Insert and secure the board connector in the selected slot.

7. Route your cables or the C-3200/C-32NN cables from the outside of
the chassis through the slot in the adapter plate and connect them to
the appropriate 40-pin header. Fold the ribbon cable so that it does
not interfere with other boards in the chassis.

8. Replace the computer chassis cover.

9. Plug in all cords and cables not already connected.

10. Continue with the next section, “Checking Your Installation.”

3-10 Setup and Installation

Checking Y our Installation

The ability to start the DriverLINX AIO Panel utility, which is available
after you install DriverLINX, verifies that DriverLINX and the board are
installed and configured satisfactorily.

You can also test the functions of the PIO-32 board, without needing to
write an application program, by connecting appropriate digital signals
and observing the responses with the DriverLINX AIO Panel.

After you configure and check your installation, you can attach
accessories as needed and wire the appropriate signals to the board. Refer
to Section 4 for instructions.

Note: The typical values shown are valid for boards with TTL

compatible outputs. For boards with relay outputs (REL-16, PDISO-8,
and PIO-32) the output will be a relay contact closure. For boards with
open collector outputs (PIO-HV) use a pull up resistor to an appropriate
voltage to detect output state. Refer to the hardware description in this
user’s guide for more details on the output’s electrical specification.

● If the bit patterns set on the AIO Panel do not agree with the

logic levels measured at the I/O terminals, the board is not
functioning properly. Stop here, and determine why.

● If the bit patterns set on the AIO Panel agree with the logic

levels measured at the I/O terminals, then repeat steps 9, 10, and
11 for remaining output channels.

Cabling and Wiring

Warning: The procedures in this section are intended for qualified

service personnel. Do not perform these procedures unless you are
qualified to do so.

After installing your PIO-32 Series boards, you can attach accessories
and wire the appropriate signals to the board. This section includes the
following information about cabling and wiring the PIO-32 Series boards:

● Description and illustration of the optional C-3200/C-32NN cables

for the PIO-32 Series boards

● Description and illustration of cabling the boards to an STP-37/FC

screw terminal panel

● Examples of typical digital I/O wiring

● Connector pin assignments

Caution: Before you make any connections to a PIO-32 Series board,

make sure that power to your computer and any accessories attached to
the PIO-32 Series board are OFF.

4-1

Optional Cables

Warning: Do not use the C-3200/C-32NN cables at voltages above

30V RMS, 42.4V peak, or 60VDC. These cables are rated for 30V RMS,

42.4V peak, or 60VDC maximum. Use at higher voltages may result in
insulation breakdown and shock hazard.

To connect the PIO-32 Series boards to screw terminal panel accessories
or other equipment, you need additional cables. You have the option of
providing your own cables or purchasing two C-3200/C-32NN cables.
The C-3200/C-32NN cables have a 40-pin ribbon connector at one end
and a 37-pin, D-type male connector at the other end. Use the 40-pin
connectors to bring the cables through the board’s rear adapter plate slot
to the headers on the board. You use the 37-D connector to attach
equipment or to wire a screw terminal panel. Figure 4-1 shows the C-3200
and C-32NN cables. Note that the C-3200 cable is 30-inches long while
the C-32NN cable has NN extra feet of cable (NN being the number of
feet added to the standard cable).

Typical Digital I/O Wiring

This section provides a typical non-TTL digital input wiring example for
the PIO-32IN board and a typical digital output control wiring example
for the PIO-32OUT board.

In the digital input example shown in Figure 4-4, the PIO-32IN board
monitors the presence of non-TTL signals. If no signal is present, the
input value is 0; if a non-TTL signal is present, the input value is 1. The
polarity matters for a digital input.

The power supply of the host
computer is too small to handle
all the system resources.

Check the needs of all system resources
and obtain a larger power supply.

If your board is not operating properly after using the information in
Table 6-1, continue with the next two sections to further isolate the
problem.

6-3

Testing the PIO-32 Series Board and Host Computer

To isolate the problem to the PIO-32 Series board or to the host computer,
perform the following steps.

Warning: Do not connect voltages greater than 30V RMS, 42.4V peak,

or 60VDC to any input or output on this board.

Live voltages can still be present on the board even when the computer is
turned off. To protect you and the circuit, Keithley provides covers with
the PIO-32 Series boards. Though you can remove the covers to service
the PIO-32 Series boards, do not use these boards with the covers
removed! In addition, disconnect all cables when servicing these boards.

1. Turn the power to the host computer OFF, and remove power
connections to the computer.

Caution: Removing a board with the power ON can cause damage to

your board and/or computer.

2. Unplug the accessory connector(s) or cable(s) from the PIO-32 Series
board(s), keeping the connections intact on the accessory board(s).

3. Remove the PIO-32 Series board(s) from the computer and visually
check for damage. If a board is obviously damaged, refer to page 6-6
for information on returning the board.

4. With the PIO-32 Series board(s) out of the computer, check the
computer for proper operation. Power up the computer and perform
any necessary diagnostics.

At this point, if you have another PIO-32 Series board that you know is
functional, you can test the slot and I/O connections using the instructions
in the next section. If you do not have another board, refer to the
instructions on page 6-6 before calling Keithley Applications
Engineering.

6-4 Troubleshooting

Testing the Accessory Slot and I/O Connections

When you are sure that the computer is operating properly, test the
computer accessory slot and I/O connections using another PIO-32 Series
board that you know is functional. To test the computer accessory slot and
the I/O connections, follow these steps:

1. Remove computer power again, and install a PIO-32 Series board that
you know is functional. Do not make any I/O connections.

2. Apply computer power and check operation with the functional
PIO-32 Series board in place. This test checks the computer accessory
slot. If you are using more than one PIO-32 Series board, check the
other slots you are using.

3. If the accessory slots are functional, check the I/O connections.
Connect the accessory boards, one at a time, and check operation.

4. If operation is normal, the problem is in the PIO-32 Series board(s)
originally in the computer. Try the PIO-32 Series board(s) one at a
time in the computer to determine which is faulty. Use the
troubleshooting information in the next section to try to isolate the
problem.

5. If you cannot isolate the problem, refer to the next section for
instructions on getting technical support.

Register Maps

Note: Address maps are provided here only for background reference

purposes. You do not program registers directly in Windows 95/98/NT.
Instead, you program register changes through the application
programming interface (API) of DriverLINX, which is provided on the
CD-ROM that comes with your board. Refer to the DriverLINX
documentation that is installed on your system. (If it is not yet installed,
you can find it on the CD-ROM in the X:\DrvLINX4\Docs and
X:\DrvLINX4\Docs\Notes folders, where X is the drive letter of the
CD-ROM drive.)

The PIO-32 Series boards contain four 8-bit registers. To maintain
compatibility with the PIO-12 products, which use an 8255
Programmable Peripheral Interface integrated circuit, the four registers
are at base addresses +0h, +1h, +4h, and +5h. Base addresses +2h, +3h,
+6, and +7h are not used. Reads or writes to these locations are ignored;
the ports are not software configurable.

Table C-1 summarizes the PIO-32 Series register maps.

Table C-2 lists the register map for the PIO-32I/O board; Table C-3 lists
the register map for the PIO-32IN board; and Table C-4 lists the register
map for the PIO-32OUT board.

Notes: In each table, the abbreviation BA is for the Base Address.

For input port bits: 0 = no current through optoisolator,

1 = current > 1.25mA (voltage > 3.5V)

For output port bits: 0 = relay is not activated (open)

1 = relay is activated (closed
