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 proce-
dures 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 mea-
surement, 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 localAC 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. A good safety practice is to expect that hazardous volt-
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 ex-
posed 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, no conductive part of the circuit
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.

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 cir-
cuit 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 in-
stalling 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 op-
erating 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 con-
nections.
If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation re-
quires 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 WARNING heading in a manual explains dangers that might result in personal injury or death. Always read the
associated information very carefully before performing the indicated procedure.
The CAUTION heading in a manual explains hazards that could damage the instrument. Such damage may invalidate
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.

Overview
The DAS-1800ST/HR Series of data acquisition boards consists of the
following basic models: DAS-1801ST, DAS-1802ST, and DAS-1802HR.
The basic models all accept analog input signals and perform A/D
(analog-to-digital) conversions. If analog output is also required, these
models are available with a D/A (digital-to-analog) conversion option
under the following designations: DAS-1801ST-DA, DAS-1802ST-DA,
and DAS-1802HR-DA.
The DAS-1800ST/HR Series boards are high-performance data
acquisition boards that operate with DriverLINX software that requires:
●
an IBM PC or compatible AT (386 or Pentium CPU) with minimum
of 2 MB of memory
●
at least one CD ROM drive, one fixed disk drive, and one floppy disk
drive
●
Microsoft Windows 95/98, or Windows NT 4.0 or higher
●
a compiler supporting Microsoft Windows development
●
a mouse is highly recommended.
The DAS-1801ST is a 12-bit, high-gain board, while the DAS-1802ST is
a 12-bit, low-gain board. The DAS-1802HR is a 16-bit, low-gain board.
Major features of these boards are as follows:
●
The boards make 16-bit data transfers on the AT bus.
●
The boards are software-configurable for 16 single-ended or eight
differential onboard analog input channels or up to 256 analog input
channels using expansion accessories.
●
Channels are individually software-configurable for gain.
●
DAS-1800ST Series boards acquire data at up to 333 ksamples/s and
12-bit resolution.

1-2 Overview
●
DAS-1802HR boards acquire data at up to 100 ksamples/s and 16-bit
resolution.
●
DAS-1800ST-DA Series boards contain four 12-bit DACs
(digital-to-analog converters) whose channels are updated
simultaneously.
●
DAS-1802HR-DA boards contain two 16-bit DACs that are updated
simultaneously.
●
A 1024-location FIFO (first-in, first-out data buffer) ensures data
integrity at all sampling rates.
●
A 256-location channel-gain queue supports high-speed sampling at
the same or different gains, in sequential or non-sequential channel
order, and at the board’s maximum acquisition rate.
●
Burst-mode data acquisition emulates simultaneous-sample-and-hold
(SSH) capability.
●
The DAS-1800ST Series boards support external SSH hardware;
DAS-1800ST Series boards support EXP-1800 expansion accessories
operated at gains of 1 and 50, while DAS-1802HR boards support
EXP-1800 accessories at a gain of one only.
●
External expansion accessories allow a board to acquire data from up
to 256 channels at the board’s maximum acquisition rate.
●
Dual-channel DMA (Direct Memory Access) operation allows the
acquisition of more than 64 ksamples.
●
Pulsed interrupts allow multiple boards to share interrupt levels.
●
Hardware trigger and gate for A/D conversions have
software-selectable polarity.
●
Triggering capabilities support pre-, post-, and about-trigger
acquisitions.
● The boards have four digital inputs.
●
The boards have four digital outputs with a latch strobe.
●
All user connections are made through the 50-pin main I/O connector
at the rear panel of the computer.
●
All features are software-programmable except for a board’s base
address switch.
●
The boards provide ±15V and +5V power for external circuitry.
