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.

Input Circuitry

The PIO-32I/O has 16 digital input channels and uses the J1 ribbon
header (channels 0 to 15). The PIO-32IN has 32 digital input channels
and uses the J1 and J2 ribbon headers (channels 0 to 31). Figure 2-2
shows each input channel schematically. You must limit the input voltage
to 28VDC and the input current to 15mA maximum. The positive input
signals are labeled PnP (where n is the bit number, 0 to 31); the negative
input signals are labeled P

nN (where n is the bit number, 0 to 31).

Output Circuitry

The PIO-32I/O has 16 digital output channels and uses the J2 ribbon
header (channels 16 to 31). The PIO-32OUT has 32 digital output
channels and uses the J1 and J2 ribbon headers (channels 0 to 31).
Figure 2-3 shows the output channels schematically. The output channels
are reed relays (form A) rated to 10W at 0.75A or 30V RMS, 42.4V peak,
or 60VDC maximum (resistive). The relay connections are not polarized
(positive or negative equivalent) and are labeled PnP and PnN (where n is
the bit number, 0 to 15).

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.
