3.2 CONNECTING SIGNALS TO THE PCI-DAS08

The simplest way to connect signals to the PCI-DAS08 is via the C37FF-x series cable and the CIO-MINI37 screw terminal
board. The PCI-DAS08 (via the C37FF-X cable) is also compatible with a wide variety of external signal conditioning
boards. These include the CIO-EXP16, CIO-EXP32, CIO-EXP-RTD16, CIO-EXP-BRIDGE16 and ISO-RACK08.

4.0 ANALOG CONNECTIONS

4.1 ANALOG INPUTS

Analog signal connection is one of the most challenging aspects of applying a data acquisition board. If you are an Analog
Electrical Engineer then this section is not for you, but if you are like most PC data acquisition users, the best way to
connect your anal og inputs may not be ob vious. Though comple te coverage o f this topic is well beyond the scope of this
manual, the following section provides some explanations and helpful hints regarding these analog input connections. This
section is designed to help you achieve the optimum performance from your PCI-DAS08 series board.

Please note that the PCI-DAS08 inputs are single-ended only. In some applications, this may make the PCI-DAS08 less
suitable than a board that provides differential inputs. Prior to j umping into actual connection schemes, you should have at
least a basic understanding of Single-Ended/Differential inputs and system grounding/isolation. If you are already comfort­able with these concepts you may wish to skip to the next section (on wiring configurations).

4.1.1 Single-Ended and Differential Inputs

The PCI-DAS08 provides 8 single-ended input channels. The concepts of single-ended and differential inputs are discussed
in the following section.

Single-Ended Inputs

A single-ended input measures the voltage between the input signal and ground. In this case, in single-ended mode the
PCI-DAS08 measures the voltage between the input channel and LLGND. The single-ended input configuration requires
only one physical connection (wire) per channel and allows the PCI-DAS08 to monitor more channels than the (2-wire)
differential configuration using the same connector and onboard multiplexor. However, since the PCI-DAS08 is measuring
the input voltage relative to its own low level ground, single-ended inputs are more susceptible to both EMI (Electro
Magnetic Interference) and any ground noise at the signal source. The following diagrams show the single-ended input
configuration.

Differential inputs measure the voltage between two distinct input signals. Within a certain range (referred to as the common
mode range), the measurement is almost independent of signal source to A/D input ground variations. A differential input is
also much more immune to EMI than a single-ended one. Most EMI noise induced in one lead is also induced in the other,
the input only measures the difference between the two leads, and the EMI common to both is ignored. This effect is a
major reason there is twisted pair wire as the twisting assures that both wires are subject to virtually identical external influ­ence. The diagram below shows a typical differential input configuration.

If the inputs you are monitoring have a significant common mode voltage, the PCI-DAS08 board may not be suitable
without the addition of some type of external signal conditioning (e.g. CIO-EXP32 or ISO-RACK08). However, as long at
the common mode voltage is small (typically less than 1 volt), you can try the board without risk of damaging the board, and
depending on the application, you may receive acceptable results.

WARNING

If either the AC or DC voltage is greater than 5 volts, do not connect the PCI-DAS08 to this signal
source. You are beyond the boards usable input range and will need to either adjust your grounding
system or add special Isolation signal conditioning to take useful measurements. A ground offset
voltage of more than 30 volts will likely damage the PCI-DAS08 board and possibly your computer.
Note that an offset voltage much grea ter than 30 volts will not only damage your electronics, but it may
also be hazardous to your health.

5.0 PROGRAMMING & SOFTWARE APPLICATIONS

Your PCI-DAS08 is supported by the powerful Universal Library. We strongly recommend that you take advantage of the
Universal Library as your software interface. The complexity of the the registers required for automatic calibration
combined with the PCI BIOS's dynamic allocation of addresses and internal resources makes the PCI-DAS08 series very
challenging to program via direct register I/O operations. Direct I/O programming should be attempted only by very experi­enced programmers.

Except for the registers required to implement plug-and-play, the PCI-DAS08 is register compatible with the CIO-DAS08
board. However, due to the dynamic nature of base addresses on the P CI bus, software written at the register level for the
CIO-DAS08 board may not work reliably on the PCI-DAS08. However, software written based on the Universal Library
will work with the PCI-DAS08 with few or no changes.

5.1 PROGRAMMING LANGUAGES

The Universal Library provides complete access to the PCI-DAS08 functions from the full range of Windows programming
languages. If you are planning to write progra ms, or would like to run the example pro grams for Visua l Basic o r any other
language, please turn now to the UniversalLibrary manual.

The optional VIX Components package may greatly simplify your programming effort. VIX Components is a set of
programming tools based on a DLL interface to Windo ws languages. A set of VBX, OCX or ActiveX interfaces allows
point and click construction of graphical displays, analysis and control structures. Please see the catalog for a complete
description of the package.

5.2 PACKAGED APPLICATION PROGRAMS

Many packaged application programs, such as DAS Wizard and HP-VEE now have drivers for the PCI-DAS08. If the
package you own does not appear to have drivers for the PCI-DAS08 please fax or e-mail the package name and the
revision number from the install disks. We will research the package for you and advise how to obtain PCI-DAS08 drivers.

Some application drivers are included with the Universal Library package, but not with the Application package. If you
have purchased an application package directly from the software vendor, you may need to purchase our Universal Library
and drivers. Please contact us for more information on this topic.

6.1 REGISTER OVERVIEW

6.0 PCI-DAS08 REGISTER DESCRIPTION

PCI-DAS08 operation registers are mapped into I/O address space. Unlike ISA bus designs, this board has
addresses each corresponding to a reserved block of addresses in I/O space. As we mention in our programming chapter,
we highly recommend customers use the Universal Library package. Direct register level programming should be attempted
only by extremely experienced register level programmers.

Of six Base Address Regions (BADR) available in the PCI 2.1 specification, two are implemented in this design and are
summarized as follows:

OperationsFunctionI/O Region

32-Bit DWORDPCI Controller Operation RegistersBADR0
16-Bit WORDGeneral Control/Status RegistersBADR1

BADR1 will likely be different on different machines. Assigned by the PCI BIOS, these Base Address values cannot be
guaranteed to be the same even on subsequent power-on cycles of the same machine. All software must interrogate BADR0
at run-time with a READ_CONFIGURATION_WORD instruction to determine the BADRn values.

several

base

6.2 BADR0

BADR0 is reserved for the 9052 PCI Controller operations. There is no reason to access this region of I/O space for most
PCI-DAS08 users. The installation procedures and Universal Library access all required information in this area. Unless
you are writing direct register level software for the PCI-DAS08, you will not need to be concerned with BADR0 address.

PCI9052 REGISTER FUNCTION

CNTRL; Local 50h

This register, as with all the 9050 registers, is 32-bits in length. Therefore the remaining bits will need to be masked off in
order to access on the OUT0 general purpose I/O bit.

Bit 0 enables the OUT0 function (0-enabled, 1-disabled) and should be set to 0
Bit 1 selects the OUT0 bit direction (0-input, 1-output) and should be set to 1

OUT0 selects the source for the interrupt latch.
OUT0 = 0, Interrupt input = user connector
OUT0 = 1, Interrupt input = counter 2 output.

6.3 BADR1

In addition to the BADR0 registers, the PCI-DAS08 uses 8 consecutive addresses in the PCI I/O space. The table below
summarizes this address map, while the remainder of this chapter provides details on the function and usage of each of the
registers.

Note that these registers are identical to those of the CIO-DAS08.

The control register is used to set the operating Modes of 8254 Counters 0,1 & 2. A counter is configured by writing the
correct Mode information to the Control Register, then the proper count data must be written to the specific Counter Regis­ter. The Counters on the 8254 are 16-bit devices. Since the interface to the 8254 is only 8-bits wide, Count data is written
to the Counter Register as two successive bytes. First the low byte is wr itten, then the high byte. The Control Register is
8-bits wide. Further information can be obtained on the 8254 data sheet, available from Intel or Harris.
