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.

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.

Features and Operating Characteristics

The PIO-HV is a 24-line, parallel, high-voltage, digital I/O interface
board that can provide a flexible interface for a variety of parallel I/O
devices, including relays, instruments, and displays.

The PIO-HV board is designed for IBM® PC series computers and
compatibles. The software currently supplied with these boards requires
the Windows
microprocessor (preferably a Pentium microprocessor).

The main features and operating characteristics of the PIO-HV are as
follows

The PIO-HV has three 8-bit digital I/O ports. Port A is an output port,

●

port B is an input port, and port C can be switch-selected as either an
input or output port. When the PIO-HV is installed in a computer, the
Port C Direction switch is accessible through the back panel of the
computer; you can use software to read the position of this switch.

All output ports use open-collector transistors that can sink up to

●

25mA when turned on, and withstand up to 50VDC when turned off.
Writing a 1 to a bit turns the corresponding transistor on.

®

95/98/NT operating system and a compatible

:

●

Port B consists of a photo diode in series with a 1.5kΩ resistor.
Applying a voltage greater than 3.5VDC and less than 32V produces
a 0 in the corresponding bit.

●

Port C, when set for input, uses conventional diodes in series with
photo diodes and a 1.5kΩ resistor. Applying a voltage greater than

4.0VDC and less than 32V produces a 0 in the corresponding bit.

●

The PIO-HV performs 10-bit I/O address decodes and communicates
with the PC bus as an 8-bit peripheral. The address map uses four
consecutive I/O addresses. You can install multiple PIO-HVs in a
computer at different base addresses.

1-2 Overview

Supporting Software

DriverLINX software is supplied by Keithley with the PI0-HV 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

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

Supporting Software 1-3

Accessories

The following accessories are available for the PIO-HV:

●

STA-U

is a universal screw-terminal accessory that connects to the
main I/O connector of the PIO-HV through a C-1800 cable to bring
all I/O signals to convenient screw terminals.

●

STC-37

is a screw-terminal panel with a connector that plugs directly
into the main I/O connector of the PIO-HV to bring all I/O signals to
convenient screw terminals.

●

STP-37/FC

is a screw terminal accessory that connects to the main
I/O connector of the PIO-HV through a C-1800/M cable to bring all
I/O signals to convenient screw terminals. The traces on this panel are
encased to prevent the exposure of high voltages to users or the work
surface.

●

SFC-37

is a mating connector for the main I/O connector of the
PIO-HV. This connector provides solder cups for direct attachment of
field wiring.

●

C-1800

is a cable terminated at each end with 37-pin, D-type, female
connectors for connecting an STA-U to the main I/O connector of the
PIO-HV. This cable is available in any desired length.

C-1800/M

●

is a cable terminated with a 37-pin, D-type female
connector at one end and a 37-pin, D-type male connector at the other
end for connecting an STP-37/FC to the main I/O connector of the
PIO-HV. This cable is available in any desired length.

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

2. Determine the resources your PIO-HV 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-HV board.

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