CAUTION
CAUTION
The discharge of static electricity can damage some electronic components.
Semiconductor devices are especially susceptible to ESD damage. You should
always handle components carefully, and you should never touch connector pins or
circuit components unless you are following ESD guidelines in an appropriate ESD
controlled area. Such guidelines include the use of properly grounded mats and
wrist straps, ESD bags and cartons, and related procedures.
Introduction
The term “DBK” typically refers to a card or module that is used to expand or enhance a primary data
acquisition device, such as a DaqBook, DaqBoard, or LogBook. As will be seen in the upcoming DBK
identification tables, DBKs provide a wide variety of data acquisition functions. Depending on the DBKs
used, one or more of the following can be realized:
• signal conditioning
• analog output
• digital I/O
• channel expansion
• supplying powering to another acquisition device
• providing an interface for different connectivity; for example, in a DaqBoard/2000 Series board,
converting a P4, 100-pin connector to P1, P2, and P3 37-pin, DB37 connectors.

How Do DBKs Connect to the Data Acquisition Device?
Each DBK connects to the primary data acquisition device; e.g., a DaqBook, DaqBoard, or LogBook,
through one of three 37-pin ports, which are designated as follows:
• P1 – Analog I/O
• P2 – Digital I/O
• P3 – Pulse/Frequency/High-Speed Digital I/O
Depending on the primary data acquisition device, connectivity issues differ slightly. This will be made
clear by the figures and accompanying text that follow.
Connecting DBKs to DaqBook/100/200 Series Devices, ISA-Type DaqBoards, & LogBooks
Reference Notes:
o DaqBoard/2000 Series and /2000c Series users, refer to page 4.
o DaqBook/2000 Series users, refer to page 5.
For DaqBook/100 Series and DaqBook/200 Series devices, ISA-Type DaqBoards, and LogBooks, DBK
connections are not made directly to the port, but through a CA-37-x ribbon cable, where “x” indicates the
number of expansion devices that can be connected. For example, in addition to providing a DB37
connector to interface with the primary data acquisition device, a CA-37-3 cable includes three additional
DB37 connectors. These provide a means of adding three DBKs to one por t. Use of a CA-37-16 cable will
allow up to 16 DBKs to be added. The CA-37-x cable system is excellent for DaqBooks, LogBooks, and
ISA-type DaqBoards.

The previous figure applies to LogBooks, DaqBook/100/200 Series devices, and ISA-type DaqBoards. As
will be seen elsewhere in this document, some devices do not include all three connectors, i.e., P1, P2, and
P3.
Connecting DBKs to Daq PC-Cards
The Daq PC-Card is only intended for connections to a P1 connector of a single “passive” DBK card or
module. A passive DBK card or module is one that provides a desired connectivity (such as BNCs or screw
terminals), but performs no signal conditioning.
A CA-134 Interface Cable and a CN-86-F (dual DB37 female adapter) are used to provide the DB37,
P1 connector.
Daq PC-Card Cabling
The CA-134 cable connects to a CN-86-F adapter, which then connects to a single “passive” card or module.
The passive DBKs are:
• DBK1 – 16 Connector BNC Module
• DBK11A – Screw Terminal Option Card
• DBK40 – BNC Analog Interface
Reference Note:
For information regarding the passive DBKs (DBK1, DBK11A, and DBK40), refer to
the DBK Option Cards and Modules User’s Manual (p/n 457-0905).
Daq Systems 967794DBK Basics, pg. 3
Page 14
Connecting DBKs to DaqBoard/2000 Series Boards
DaqBoard/2000 Series and cPCI DaqBoard/2000 Series boards have 100-pin connectors designated as P4.
The 100 pins correlate to various pins on P1, P2, and P3 DB37 connectors.* Connectivity in the system is as
follows (see figure).
•Both the DaqBoard/2000 and /2000c Series board connect to a CA-195 cable.
The cable has two, 100-pin, P4 connectors.
•The CA-195 connects to a DBK200 Series adapter board or adapter module for 100-pin to
37-pin adaptations, e.g., P4-to-P1, P2, P3; but not necessarily all three.*
•The DBK200 Series adapter connects to a CA-37-x ribbon cable, where “x” indicates the
number of expansion devices that can be connected. For example, in addition to providing a
DB37 connector to interface with the primary data acquisition device, a CA-37-3 cable
includes three additional DB37 connectors. These provide a means of adding three DBKs to
one port. Use of a CA-37-16 cable will allow up to 16 DBKs to be ad ded.
•The CA-37-x cable connects to expansion DBKs, in accordance with port type. For example,
Analog DBKs to port P1, Digital DBKs to port P2, and passive DBKs to port P3.
Connecting DBKs to a DaqBoard/2000 Series Board
* DaqBoard/2003 and cPCI DaqBoard/2003c are exceptions to the above connectivity method. The /2003
board typically connects directly to a DBK205 (P4-to-Screw Terminal Adapter), as discussed in the DBK Option Cards and Modules User’s Manual (p/n 457-0905).
Note: DaqBook/2000 Series Devices, which are discussed in the following section, can also connect to DBKs via
a P4 connector, as indicated in the above figure.
pg. 4, DBK Basics 967794 Daq Systems
Page 15
Connecting DBKs to DaqBook/2000 Series Devices
Several products make use of the DaqBook/2000 nomenclature. However, they do not all offer the same
connection options. Refer to pinouts for the specific devices, as needed.
Product Connects to DBK Expansions via …
DaqBook/2001 and /2005 37-pin connectors P1, P2, and P3. There is no P4.
DaqBook/2020 37-pin connectors P1 and P2. There is no P3 or P4.
DaqOEM/2001 and /2005 40-pin headers (JP1, JP2, and JP3). There is no P4.
DaqBook/2000A 37-pin connectors P1, P2, P3, and a 100-pin P4 connector.
DaqBook/2000E 37-pin connectors P1, P2, P3, and a 100-pin P4 connector.
DaqBook/2000X 37-pin connectors P1, P2, P3, and a 100-pin P4 connector.
For DaqBook/2000 Series devices, DBK connections can be made to Ports P1, P2, and/or P3 (when
applicable). For the “AEX” models a 100-pin P4 connector can be used. A discussion of both methods,
follows.
The P4 connector on a DaqBook/2000 “AEX” device shares signal connections with the
P1, P2, and P3 connectors. P4 offers no additional I/O. Connecting a DBK200 Series
Option to P4 via a CA-195 cable distances the P1, P2, P3 connection from the
DaqBook/2000 Series device. It does not provide any new signal I/O. See the following
Caution.
CAUTION
Signal conflicts between a DaqBook/2000 “AEX” device’s P1, P2, P3 connectors and its
P4 connector can result in erroneous readings and possible equipment damage.
Therefore, when connections have been made to P1, P2, and/or P3, use caution when
making connections through P4, and visa versa.
Refer to P1, P2, P3, and P4 pinouts to avoid making duplicate signal connections.
There are two ways to connect a DBK option to a DaqBook/2000 “AEX” device. The first
method is preferable, as it introduces less noise.
Preferred Method – (a) Connect a CA-37-x cable to the appropriate DB37 connector
[P1, P2, or P3] on the DaqBook/2000 Series device. (b) Connect the
free end of the cable to the DBK card or module.
Optional Method – (a) Connect a CA-195-x cable to the P4 connector on the
DaqBook/2000 Series device. (b) Connect the free end of the cable
to a DBK200 Series device. (c) Connect the DBK option to the
DBK200 Series device, as applicable.
The primary reason that less noise is seen in the “preferred” method is that a
DaqBook/2000 Series device’s P1 connector pertains only to analog acquisition signals
and the P2 connector pertains only to digital I/O. This provides a strong degree of
isolation between the two signal types. However, in the case of a CA-195-x cable
connected to P4, digital and analog signals co-exist in one cable.
If you need to use the P4 connection method, use of the 8-inch ribbon cable (CA-195-1)
will result in the lowest level of crosstalk [for that method].

Connecting DBKs to a DaqBook/2000 Series Device via P1, P2, and/or P3
The DBKs do not connect directly to the port, but through a CA-37-x ribbon cable, where “x” indicates the
number of expansion devices that can be connected. For example, a CA-37-3 cable includes a 37-pin mating
connector to interface with the DaqBook/2000 Series DB37 connector (P1, P2, P3); it also includes three
additional DB37 connectors. These provide a means of adding three DBKs to one port. Use of a
CA-37-16 cable will allow up to 16 DBKs to be added to one DaqBook/2000 Series device DB37-type port.

The P4 connector on a DaqBook/2000 “AEX” device shares signal connections with the
P1, P2, and P3 connectors. P4 offers no additional I/O. Connecting a DBK200 Series
Option to P4 via a CA-195 cable distances the P1, P2, P3 connection from the
DaqBook/2000 Series device. It does not provide any new signal I/O. See the following
Caution.
CAUTION
Signal conflicts between a DaqBook/2000 “AEX” device’s P1, P2, P3 connectors and its
P4 connector can result in erroneous readings and possible equipment damage.
Therefore, when connections have been made to P1, P2, and/or P3, use caution when
making connections through P4, and visa versa.
The following pinouts indicate the P1, P2, and P3 pins, and their P4 equivalents.
Use the pinouts to avoid making duplicate signal connections.

Connecting DBKs to a DaqBook/2000 “AEX” Device via P4
Every DaqBook/2000 “AEX” device has a 100-pin connector designated as P4. The P4 pins correlate to
various pins on P1, P2, and P3.
The P4 connector on a DaqBook/2000 “AEX” device shares signal connections with the
P1, P2, and P3 connectors. P4 offers no additional I/O. Connecting a DBK200 Series
Option to P4 via a CA-195 cable distances the P1, P2, P3 connection from the
DaqBook/2000 “AEX” device. It does not provide any new signal I/O. See the following
Caution.
CAUTION
Signal conflicts between a DaqBook/2000 AEX device’s P1, P2, P3 connectors and its
P4 connector can result in erroneous readings and possible equipment damage.
Therefore, when connections have been made to P1, P2, and/or P3, use caution when
making connections through P4, and visa versa.
Refer to P1, P2, P3, and P4 pinouts to avoid making duplicate signal connections.
A brief explanation of P4 connectivity for DaqBook/2000 AEX devices follows the illustration.

DaqBook/2001, DaqBook/2005, DaqOEM/2001, DaqOEM/2005, and DaqBook/2020 do
not have a P4 connector. The P4 connection option applies to “AEX” models only.
Daq Systems 967794DBK Basics, pg. 7
Page 18
P4 connectivity for DaqBook/2000 “AEX” devices is as follows:
•One end of a CA-195 cable connects to the DaqBook/2000 “AEX” device’s 100-pin P4
connector. Note that the CA-195 cable has two P4 connectors.
•The other end of the CA-195 cable connects to a DBK200 Series adapter board [or adapter
module] for 100-pin to 37-pin adaptations, e.g., P4-to-P1, P2, P3; but not necessarily all three.
•The DBK200 Series adapter connects to one or more CA-37-x ribbon cables, where “x”
indicates the number of expansion devices that can be connected. For example, in addition to
providing a DB37 connector to interface with the primary data acquisition device, a CA-37-3
cable includes three additional DB37 connectors. These provide a means of adding three
DBKs to one port. Use of a CA-37-16 cable will allow up to 16 DBKs to be added.
•The CA-37-x cable connects to expansion DBKs, in accordance with port type. For example,
Analog DBKs to port P1, Digital DBKs to port P2, and passive DBKs to port P3.
There are two ways to connect a DBK option to a DaqBook/2000 “AEX” device. The first
method is preferable, as it introduces less noise.
Preferred Method – (a) Connect a CA-37-x cable to the appropriate DB37 connector
[P1, P2, or P3] on the DaqBook/2000 Series device. (b) Connect the
free end of the cable to the DBK card or module.
Optional Method – (a) Connect a CA-195-x cable to the P4 connector on the
DaqBook/2000 Series device. (b) Connect the free end of the cable
to a DBK200 Series device. (c) Connect the DBK option to the
DBK200 Series device, as applicable.
The primary reason that less noise is seen in the “preferred” method is that a
DaqBook/2000 “AEX” device’s P1 connector pertains only to analog acquisition signals
and the P2 connector pertains only to digital I/O. This provides a strong degree of
isolation between the two signal types. However, in the case of a CA-195-x cable
connected to P4, digital and analog signals co-exist in one cable.
If you need to use the P4 connection method, use of the 8-inch ribbon cable (CA-195-1)
will result in the lowest level of crosstalk [for that method].
The CE Cable Kit, p/n CA-209D, may be required for systems that require a P4 cable
length of 3 feet. The CA-209D kit includes a shielded version of the CA-195 cable, two
grounding pigtails, and associated cable clamps. When properly connected, the shielded
cable provides greater immunity to noise. The CE Compliance chapter includes details.

Analog Signal Conditioning DBKs
The DBKs that are used for analog signal conditioning attach to transducers and condition their outputs into
analog voltages. An A/D converter, located in the primary acquisition device, measures the analog voltages.
There are many signal-conditioning solutions available (and more are in development). Note that DBK
high-capacity modules require more circuitry than can fit on a compact card.

Expansion and Terminal Panel Connection DBKs
The following DBKs offer provide various expansion and connection options. The stackable 3-slot DBK10
low-profile enclosure can be used for up to three DBKs. If a system has more than 3 DBKs, the 10-slot
DBK41 can be used. Several DBK41s can be daisy-chained to accommodate many DBKs in one system.
Several signal connection options were developed primarily for use with DaqBoard/2000 Series and
cPCI DaqBoard/2000c Series Boards. The DBK200 Series P4-Adapter documentation provides the basic
connection concepts. That information, along with the related DBK subsections should enable you to set up
your desired configuration.

Power Supply DBKs
Power supply type DBKs are typically used in laboratory, automotive, and field applications. Input power
can come from any +10 to +20 VDC source, or from an AC source by using an appropriately rated AC-toDC adapter. The DBK30A rechargeable power supply can power DBK modules where AC mains are not
available (the DBK30A outputs 28 V for powering transducers). For a large number of DBK cards, the
DBK32A or DBK33 can be installed into an expansion slot. The DBK33 is used when +5 V is required in
addition to ±15 VDC. The DBK34 provides a steady 12 or 24 VDC while working with vehicle electrical
systems that may be turned on or off during testing.

Tips on Setting up a Data Acquisition System
A successful installation involves setting up equipment and setting software parameters. In addition to this
manual, you may need to consult your Daq device or LogBook user’s manual.
DBKs should be configured before connections are made and power is applied. This sequence can prevent
equipment damage and will help ensure proper operation on startup. Many DBKs have on-board jumpers
and/or DIP switches that are used for setting channels and other variables. You will need to refer to the
individual DBK document modules to ensure that the DBKs are properly configured for you application.
Prior to designing or setting up a custom data acquisition system, you should review the following tips.
After reviewing the material you can write out the steps to setup a system that will best meet your specific
application needs.
1. The end use of the acquisition data should be used to determine how you set up and program your
acquisition system. Prior to creating the system you should understand its layout and know how you are
going to assign the channels. If you can answer the following questions you are off to a good start. If
not, you need to find the answers.
• What engineering units, ranges, sampling rates, etc. are best for your data?
• Will the data be charted graphically, statistically processed, or exported to other programs?
• How will the data be used?
• How will the data be saved?
• What are the system power requirements? Using several DBKs or transducers that require
excitation current may require an extra power supply, e.g., a DBK32A.
2. Assign channel numbers.
3. Plan the location of transducers, cable runs, DBKs, the acquisition device [LogBook or Daq device],
and the computer. Label your transducers, cables, and connectors to prevent later confusion.
pg. 12, DBK Basics 967794 Daq Systems
Page 23
4.When configuring your LogBook or Daq device(s) consider the following:
•LogBook calibration is typically performed automatically through LogView software;
however, some DBKs may require manual calibration.
•The DaqBook/100 Series and DaqBook/200 Series devices, and DaqBoards (ISA type)
have internal jumpers and switches that you must set manually to match your
application.
•Some DaqBook/100 Series and DaqBook/200 Series models are partially configured in
software.
•DaqBook/2000 Series devices have no jumpers or internal switches and are configured
entirely through software.
• Daq PC-Cards are configured entirely in software.
• DaqBoard/2000 Series boards are PCI type boards. They have no jumpers or switches and
are configured entirely through software.
•cPCI DaqBoard/2000c Series boards are compact PCI (cPCI) type boards. They have no
jumpers or switches and are configured entirely through software.
• You may need to refer to other documentation, such as Quick Starts, Installation Guides,
User’s Manuals, and pertinent DBK document modules.
5. Perform all hardware configurations before connecting signal and power. Remember to
configure all the DBK cards and modules for your application. Several jumpers and DIP switches
may need to be set (channel, gain, filters, signal mode, etc).
6. Setting up channel parameters often requires both hardware and software setup.
7. Route and connect all signal and power cables while all power is turned OFF.
8. To minimize electrical noise, route all signal lines away from any RF or high-voltage devices.
9. Follow your device’s specific installation instructions. For certain devices software should be installed
first; for others, hardware should be installed prior to software installation.
10. After software is loaded, remember to set the software parameters as needed for your application.
The software must recognize all the hardware in the system. Measurement units and ranges
should be checked to verify that they meet your application requirements.
11. Remember to set all channels to the proper mode for your DBK or other signal source.
12. After your system is up and running, verify proper data acquisition and data storage.
13. Verify system accuracy; adjust ranges or calibrate as needed.
14. Device specific information regarding system setup and expansion can be found in the Daq and
LogBook User’s manuals; and in the applicable DBK document modules of this manual.
15. If you are considering system expansion, review the DBK10, DBK41, and DBK60 document modules.
The best option depends on the number of DBK cards in your system. For just a few cards, use the
stackable 3-slot DBK10 low-profile expansion enclosure. For more than six cards, use the 10-slot
DBK41. DBK41s can be daisy-chained to one-another to handle a large number of DBKs.
In regard to power management, you should review the DBK30A, DBK32A, and DBK33 document

modules. For portable applications, the compact DBK30A rechargeable power supply can provide
power to the DBK10 or DBK41. The DBK30A also includes a 28 V output for powering 4 to 20 mA
transducers. For applications with many DBK cards (initially or in future expansion), the DBK32A or
DBK33 can be installed into any expansion slot. The DBK32A provides ±15 VDC and the DBK33
provides ±15 VDC and +5 VDC.

Power Supplies and Power Connectors
Power supplies convert the raw power they receive into a lower DC voltage and/or current for use by
devices with various power demands. Many of the power supplies that are used to power data acquisition
equipment are of the switching-mode type. These devices provide a regulated output whether the power
supply’s input is, for example, 60 Hz, 120 VAC as in the United States or, 50 Hz, 220 VAC as found in
European countries. Small power supplies, that do not switch, consist of simple transformer/rectifiers and
filtered capacitors; and operate over a smaller voltage range.
Some manufacturers improve the power output of their units over time, without changing the model
number. For example, one very popular power supply was previously rated at 15 VDC @ 2.7 amps, yet
more recent versions of the same model number are rated 15 VDC @ 3.3 amps. Read the manufacturer’s
information pertaining to your power supplies so you don’t accidentally overload the supply.
DBKs – The following table indicates the type of power supply that is typically used with certain DBKs.
These DBKs can be powered from a
Switching-Mode Type Power Supply
The switching-mode power supply typically
receives power from a 100 to 240 VAC source at 50
Hz to
60 Hz and converts it to the 15 VDC required by the
DBK.
The DIN5 is the system’s basic power connector (see the following figure). The CA-115 is a 6-in. cable
with a plug (male) DIN5 connector on both ends. The CA-115 is used to connect DBK32As [or DBK33s]
in parallel when they are to be powered by the same power supply.

An Introduction to Power-Related DBKs
The power-related DBK options are the DBK30A, DBK32A, DBK33, DBK34, and DBK34A. From the
standpoint of providing reliable power, these DBKs have proven convenient in laboratory, automotive, and
field applications.
Input power for these devices can come from any 10 to 20 VDC source, or from an AC source via an
appropriate AC-to-DC adapter.
A brief synopsis of the DBK power options follows. Refer to the respective document modules for complete
information.
DBK30A module - provides power at 14 and 28 VDC with a rated capacity of 3.4 A-hr @ 14 VDC.
The DBK30A’s 28 V output will power 4 to 20 mA transducers.
power DBK modules in situations where AC mains are not available.
Note: Some transducers (e.g., 2-wire 4-20 mA transmitters, bridge-configured sensors, etc) require an
excitation voltage in order to work properly. The DBK30A supplies 14 and 28 VDC. Consult
transducer documentation before applying power.
The module’s rechargeable power supply can
DBK32A - provides ±15 VDC @ 500 mA.
DBK33 - provides ±15 VDC @ 250 mA and +5 VDC @ 1000 mA.
The DBK32A and DBK33 power cards attach directly to the P1 analog expansion bus where they supply
power to DBK analog expansion cards. The DBK32A and the DBK33 can be powered from an included AC
adapter, an optional DBK30A battery module, or from a +10 to +20 VDC source such as a car battery.
When installed in a DBK10 three-slot expansion chassis, the DBK32A or DBK33 supplies power
to the analog DBK [that is to receive power] via a CA-37-x cable.
If used with the DBK41 ten-slot expansion enclosure, the DBK32A or DBK33 installs into one of the analog
expansion slots on the DBK41’s backplane. A power card in any DBK41slot (other than the leftmost, when
viewed from the rear) will power the other cards that are connected to the DBK41’s backplane.
CAUTION
If using a DBK32A or a DBK33 with a DaqBook/100 Series, DaqBook/200 Series, or a
DaqBoard [ISA type] device, you must entirely remove the shunt jumpers from JP1.
Failure to do so will result in damage to the 8254 timer chip. Refer to the power card
document modules and to the Daq device Hardware sections of the DaqBook/100 Series
and DaqBook/200 Series, and DaqBoard [ISA] user’s manuals for JP1 locations and
configurations.
DBK34A module – provides 12 or 24 VDC with a 5.0 or 2.5 A-hr capacity (respectively).
The DBK34A is classified as a UPS / Battery module. The module can be used for in-vehicle testing
in scenarios where the vehicle’s electrical system does not affect acquisition device power during
starter-current surge, or power-off.

Power Requirements
The improper use of power can cause system damage. The following terms are important in regard to
understanding your system’s power needs.
•Supply power for signal conditioning type DBKs comes from a primary acquisition device,
such as a DaqBook/2000 Series device or LogBook, or from a power card or module. If
needed, the DBK32A or DBK33 can provide additional power to meet DBK power demands.
The DBK power supplies work off of low-voltage DC that can come from an AC adapter or
from a DC source, such as a car battery.
•Demand for power comes from DBK cards and modules [and in some systems, from
transducers]. You should use the DBK Power Requirement Worktable to calculate your
system’s power needs. After completing the table, compare the total power demand to the
supply power.
•Distribution of power to most DBKs is via the P1 interface. The DBK41 expansion chassis
has a jumper to isolate +5 VDC power from P1. The P1 Pin designations are as follows:
Pin 1: +5 VDC
Pin 2: -15 VDC
Pin 21: +15 VDC
Pin 7: digital ground
Pin 28: analog ground
Pin 29: analog ground
Note: Certain DBK modules have their own internal power supplies and require only 10 VDC to 20 VDC.
LogBook
The LogBook [with no DBKs attached] uses approximately 12 Watts of power. If using battery-power, you
can compute operational endurance from your battery’s watt×hr rating and the following calculation tables.
DaqBoard/2000 Series Boards
DaqBoard/2000 Series and cPCI DaqBoard/2000c Series Boards use 3.5 watts of power
(700 mA @ 5 VDC) from their host computer. Power consumption can be up to 10 W with external
accessories.
Avoid power cycling the host PC. Wait 10 seconds after powering down the host PC before powering it
back on. This will allow any residual voltages to decay enabling the DaqBoard/2000 Series or /2000c Series
board to start up in a known good state.
DaqBook/100 Series & /200 Series, DaqBoard [ISA], and Daq PC-Card
If using power from AC mains (through adapter), you need not worry about Daq device power use. If using
battery-power, you can compute operational endurance from the battery’s watt×hr rating and power tables.
Daq PC-Card and DaqBoard use power from their host PC.
DaqBook/100 and DaqBook/200 Series devices use no power from the PC, but do require DC voltage from
an AC-to-DC adapter, or another suitable source. Voltage needs are as follows:
• +7 to +20 VDC for DaqBook/100, DaqBook/112, and DaqBook/120
• +10 to +24 VDC for DaqBook/216
• 9 to +18 VDC for DaqBook/200 and DaqBook/260.
Various AC adapter models support power grids of USA, Europe, Japan, and Asia.

Signal Modes
Input signals come in one of two modes, single-ended or differential. Expansion modules, LogBook, and
Daq device default setting use the single-ended mode. Some DBKs use differential inputs for certain kinds
of transducers; but DBK output is always single-ended. The following text briefly describes the two signal
modes.
Note: For DaqBook/100, /112, /120, jumper settings determine the signal mode. Single-ended is the
Single-ended mode refers to a mode, or circuit set-up, in which a voltage is measured between 1 signal line
and common ground voltage (Vcm). The measured voltage may be shared with other channels. The
advantage of a single-ended non-differential mode [over differential mode] is that it provides for a higher
channel count (16 vs 8 channels).
Differential-mode refers to a mode, or circuit set-up, in which a voltage is measured between 2 signal
lines. The resulting measured differential voltage is used for a single channel. Differential inputs reduce
signal errors and the induction of noise from ground current. The following illustration is an example of
how noise is reduced, or canceled-out, when using the differential mode.
In the schematic, voltage signal S
spikes with the same polarity, phase, and magnitude in each input signal cancel out—resulting in a clean

Input Isolation
Three benefits of input isolation are circuit protection, noise reduction, and the rejection of high common
mode voltage.
•Circuit protection. Input isolation separates the signal source from circuits that may be damaged by
the signal. (Voltages higher than about 10 V can distort data or damage chips used in data
acquisition.) High-voltage signals or signals with high-voltage spikes should therefore be isolated.
The protection can also work the other way—to safeguard a sensitive signal conditioner from a
failing device elsewhere in the system.
•Noise reduction. Isolation eliminates ground loops for high-gain systems and multi-unit systems that
are grounded together. The chassis for each device can rest at a ground potential slightly different
from the other devices. These irrelevant currents and the spikes they may have picked up by
induction can thus be kept out of the measurement circuit.
•Rejection of high common-mode voltage. There is a limit to the voltage applied to a differential
amplifier between ground and the amplifier inputs. Fortunately, the differential amplifier rejects high
common-mode voltage signals. High common-mode voltage and noise spikes are rejected (canceled
out) in in-phase signals (same amplitude and frequency) that are present in both the high and low
inputs at the same time.
References for Differential Modes
There are three basic types of measurement configuration related to differential mode; these are groundreferenced, shunt-referenced, and floating.
Differential Mode, Ground-Referenced
In ground-referenced configurations, the signal voltage is
referenced to a local common ground. In most cases, the local
ground will be at a different voltage potential from the PC’s
ground.
Differential inputs provide attenuation of the common-mode
noise. When in this mode, the amplifier sees the voltage
differential between the high and low inputs (see figure).
Common-mode noise reduction occurs because noise in the
high input signal is typically the same as the noise in the low
input signal. Because of this phenomena, the voltage
difference between the 2 signals remains essentially unaffected
by noise spikes, since these spikes appear at the same instant
and at the same magnitude in both the high and low input
signals. In other words, the noise spikes cancel each other out.
As noted earlier, even if these signals were out-of-phase, the
noise would still cancel out since the spikes in both signals
would be of the same magnitude and polarity.
Note: In the simple example (shown in the figure), the
differential between the high and low signals would result in a straight line because the signals are
equal in frequency, phase, and magnitude.
Differential Mode, Shunt-Referenced
There are situations in which small voltages need to be measured and the currents flowing in the power
supply common will cause measurement errors. As shown in the figure, using the analog common as the
reference point will result in errors. These errors are the result of variations in current flow along the
common line [(I3 * Z3) + (I3 & I2) * Z2].

Differential Circuit with Shunt-reference
A way around this problem is to use a differential measurement for each shunt, with the instrument
common connected to the supply common. Each input channel will measure the shunt voltage and will
reject any voltage in the common wire (common-mode rejection).
Differential Mode, Floating (Isolated from Ground)
Floating-differential measurements are made when low-level signals must
be measured in the presence of high levels of common-mode noise (e.g., a
T/C

(-)

non-grounded thermocouple). When the signal source has no direct
connection to the system analog common, one must be provided. This can
be done by connecting a resistor between one of the two signal lines;
usually the lower in potential and common. A resistor of 10 to 100 kΩ is
satisfactory (less noise with the lower values).

Floating Diffe rential Circuit
Do not use differential signal hookups with the intent of achieving isolation or circuit
protection. Differential signal hookups do not provide isolation, or any other kind of
circuit protection.
Connecting Differential Amplifiers
Wire connections must be solid. Loose wires will add noise to the circuit. Low grade unshielded cables
will act as antennas, inducing more noise into the system. For this reason, all applications using a
differential amplifier require the use of quality signal cables and connectors. The signal cable used should
be constructed with:
• Insulated outer jacket
• Twisted signal pairs
• Foil shield

multiple folds.
The copper-stranded drain wire should be considered as part of the shield, and should be connected as
described later in this section. Proper use of a quality signal cable will result in a dramatic reduction of
noise.
The signal circuit must be connected with only one ground from the shield, as indicated in the left side of
the figure below. A mistake, which is often made, is having two grounds (one at each end of the signal
shield). Having two grounds, as shown in the right side of the figure, creates a “ground loop.” The ground
loop provides a path for current to circulate, causing the induction of noise that can affect the signal.

Aside from eliminating noise-inducing ground loops, the use of bias resistors should also be considered
with isolated signal sources. Bias resistors can be used to provide bias current for the positive and negative
(high and low) input signals to the differential amplifier. The impedance value of the bias resistors
depends on the output impedance of the signal source.

.. Bias resistors should be located as close as possible to the
differential amplifier. Ground only one end of the signal shield.
Unipolar and Bipolar Measurement
Unipolar signals are always zero or positive. Bipolar signals can be negative or positive and typically
range from -5 to +5 V (-10 to +10 V for the /2000 Series Devices). Using one or the other depends on the
signal from the transducer and its signal conditioning. If the DBK (or other signal conditioner) outputs a
bipolar signal, then the LogBook or Daq device should be set to bipolar. If the LogBook or Daq device
sequencer is using the wrong mode for a channel, that channel’s reading may be clipped or in error.
Reading a bipolar signal in unipolar mode misses half the signal, and the half received is not converted
with optimal resolution.
Note: The different DBKs can use either or both signal modes. Refer to the DBK documentation, and
verify that the DBK and the LogBook or Daq device are set to the proper mode for each channel.
12-Bit vs 16-Bit Resolution
An analog-to-digital converter (ADC) converts an analog voltage to a digital number. The digital number
represents the input voltage in discrete steps with finite resolution. The number of bits that represent the
digital number determines ADC resolution. An n-bit ADC has a resolution of 1 part in 2
• 12-bit resolution is 1 part in 4096 (in binary powers, 2

System Noise
Electrical noise can present problems even with good equipment; thus, controlling noise is imperative.
Some techniques avoid or prevent noise sources from entering the system; other techniques remove noise
from the signal.
Laboratory and industrial environments often have multiple sources of electrical noise. An AC power line
is a source of 50/60 Hz noise. Heavy equipment (air conditioners, elevators, pumps, etc.) can be a source
of noise, particularly when turned on and off. Local radio stations are a source of high-frequency noise,
and computers and other electronic equipment can create noise in a multitude of frequency ranges. Thus,
an absolute noise-free environment for data acquisition is not realistic. Fortunately, noise-reduction
techniques such as averaging, filtering, differential voltage measurement, and shielding are available to
reduce noise to an acceptable level.
Note: Additional noise-reduction information is contained in the section, “Signal Modes,” especially in the
Averaging
Averaging is done in software after several samples have been collected. Depending on the nature of the
noise, averaging can reduce noise by the square root of the number of averaged samples. Although
averaging can be effective, it suffers from several drawbacks. Noise in measurements only decreases as
the square root of the number of measurements—reducing RMS noise significantly may require many
samples. Thus, averaging is suited to low-speed applications that can provide many samples.
Note: Only random noise is reduced or eliminated by averaging. Averaging will not reduce or eliminate
paragraphs pertaining to connections, signal cables, and ground loops.
any signal that is periodic.
Analog Filtering
A filter is an analog circuit element that attenuates an incoming signal according to its frequency. A lowpass filter attenuates frequencies above the cutoff frequency. Conversely, a high-pass filter attenuates
frequencies below the cutoff. As frequency increases beyond the cutoff point, the attenuation of a singlepole, low-pass filter increases slowly. Multi-pole filters provide greater attenuation beyond the cutoff
frequency but may introduce phase (time delay) problems that could affect some applications.
Filter circuits can be active or passive:
•Active. The DBK18 Low-Pass Filter Card has an instrumentation amplifier with variable gain and
filter configurations. The DBK18 uses an active 3-pole filter (mostly contained within the UAFF42
ICs) that can be configured as a Butterworth, Bessel, or Chebyshev filter with corner frequencies up
to 50 kHz. Filter properties depend on the values of resistors and capacitors. These components
can be changed by the user.
•Passive. The DBK11 has a prototype area on the PC board for attaching non-powered components
such as resistors and capacitors. The user chooses component values to produce the desired
properties.

Page 38
Crosstalk
Crosstalk is a type of noise related to source impedance and capacitance, in which signals from one
channel leak into an adjacent channel, resulting in interference or signal distortion. The impact of source
impedance and stray capacitance can be estimated by using the following equation.
T = RC
Where T is the time constant, R is the source impedance, and C is the stray capacitance.
High source (transducer) impedance can be a problem in multiplexed A/D systems like the DBK12,
DBK13, DBK15. When using more than 1 channel, the channel input signals are multiplexed into the
circuit card. The multiplexer samples each signal for only 10 µs and then switches to the next input signal.
A high-impedance input interacts with the multiplexer’s stray capacitance and causes crosstalk and
inaccuracies in the A/D sample. In such cases, the source impedance should be less than 1 kΩ. If the
source impedance exceeds this value, sampling problems can be expected.
A solution to high source impedance in relation to multiplexers involves the use of buffers. The term
buffer has several meanings; but in this case, buffer refers to an operational amplifier having high input
impedance but very low output impedance. In the example illustrated, a buffer has reduced the source
impedance from 10 kΩ to effectively 0 kΩ. Placing such a buffer on each channel (between the transducer
and the multiplexer) prevents the multiplexer’s stray capacitance from combining with the high input
impedance (10 kΩ in the example). This use of a buffer also stops transient signals from propagating
backwards from the multiplexer to the transducer.
Using DBK Cards and Modules for Signal Conditioning
The DBK signal-conditioning units are designed for use with Daq devices and LogBooks. Although the
DBK options can be used with ISA or PCI bus-based data acquisition boards from other vendors; they
perform best when used with an acquisition device that can dynamically select channel, gain, and range.
Dynamic channel and gain/range make it possible to have high channel-to-channel scan rates with a variety
of transducers.
DBK output signals can be bipolar, e.g., -5 to +5 V, or unipolar, e.g., 0 to 10 V. The user can select a
range of relevant values to correspond to the lowest signal (e.g., -5 or 0 V) and the highest signal (e.g., 5 or
10 V) signal. This type of range selection guarantees the highest resolution in 12-bit or 16-bit conversion.
DBK modules share the same footprint as the DaqBooks and LogBooks. This dimensional aspect provides
for convenient stacking of modules with each other and with most notebook PCs. Note that most DBK
modules have their own power supply.

Channel Control and Expansion
In a Daq device or LogBook system, DBK expansion cards and modules can increase the number of analog
input channels from 16 base channels to 256 input channels (16 × 16). The configuration will vary
depending on the DBK’s channel capacity; for example, four 4-channel DBKs or two 8-channel DBKs can
share the same base channel. As part of the multiplexing scheme, each DBK card provides a single output
that must be directed to one of the 16 base channels via the DBK’s JP1 jumper setting.

Channel Control and Expansion Block Diagram
The above figure shows the functional parts related to channel control and expansion. An explanation of
the diagram follows.
• The sequencer selects the channel and gain by controlling multiplexers (MUX) and
programmable gain amplifiers (PGA) in either the LogBook or the Daq device and the DBK.
The sequencer uses 4 expansion address lines to provide 16 unique channel addresses for each
base channel. A 100 kHz clock and user programming of the scan sequence control the
sequencer.
Note: /2000 Series Devices allow for selection of 100 kHz, or 200 kHz internal clock speed via software.
• The DBK multiplexer selects 1 of 16 (max) channels as directed by the sequencer. The selected
signal travels to the PGA, to the channel-selection jumper, then to the Daq device, or LogBook
via P1.
• The Daq device or LogBook multiplexer selects 1 of 16 base channels from P1 input lines as
directed by the sequencer. The selected signal goes to the PGA and then to the A/D converter
(A/D).
• The PGAs can vary the gain on a per channel basis as directed by the sequencer. For DBKs
with a PGA, the sequencer can combine the gains of the DBK PGA and the LogBook or Daq
device PGA for a variety of gain settings.
• The P1 interface has a signal line for each of the 16 base channels and control lines for gain
• The JP1 channel select jumper in the DBK can be placed on pins for channel 0 through
channel 15. Until the base channel capacity is filled (16 max), multiple cards can use th e same
JP1 channel setting if their DIP switches are set to identify unique sub-channel card numbers.
Note: The channel select header on DBK17 and DBK18 is labeled J1 instead of JP1.

In addition to the base channel selection on JP1, many DBKs must be set to the sub-channel (or card)
number by a DIP-switch labeled SW1 or S1. Since DBKs vary in their channel capacity and identification,
refer to the respective DBK document modules.
Example. Refer to the above table (the 1-0 to 1-15 row) and to the following figure. To select channel 15
on a DBK card that is connected to base channel 1:
a) set the sequencer expansion address to 1111
b) set the base address to 0001
c) set JP1 to channel 1
d) Depending on the DBK, set the DIP-switch to identify one of
the multiple cards on a single channel.
The corresponding API channel number would be 47; i.e., DaqView Channel 1-15 (see table).
Note that API Channels are not used in LogBook systems.

The LogBook or Daq device holds the scan information in its internal sequencer. On every timebase
“tick”, the sequencer steps through all the programmed channels and sets the gain for each channel (also
the unipolar/bipolar setting for the /2000 Series Devices). Thus, each sample in a scan is read optimally.
In addition to controlling the LogBook or the Daq device, the sequencer controls the programmable
features on expansion cards via the P1 connector.
This architecture ensures that the same 10 µs sampling (5 µs or 10 µs for /2000 Series Devices) exists for
external channels as well as internal channels.

Most sampling of analog signals occurs on the timebase of the LogBook or the Daq device clock. The
scan period is the time duration between successive scans. Inversely, the scan rate, or scan frequency is
the number of scans per time interval, usually expressed in scans per second. The channels within the scan
are always sampled at a fixed period of 10 µs (100 kHz rate), or 5 µs (200 kHz rate); or 10 µs for the /2000
Series Devices. Generally, the sampling frequency must be greater than twice the highest signal frequency
of interest to prevent aliasing error.
Note 1: With /2000 Series Devices, either 100 kHz or 200 kHz can be selected to be used as the internal
clock speed. To ensure signal accuracy the 100 kHz speed must be selected when using a
DBK12, DBK13, DBK15, DBK19, DBK53 or DBK54 in conjunction with DaqBoard/2000
Series, or cPCI DaqBoard2000c Series boards.
Note 2: Except in the case of a single-channel scan, the sampling rate per channel can be much slower
than the scan rate.
Triggering controls an acquisition cycle. Once the system is armed, a trigger is required to collect the data.
Typically, three data collection parameters are specified: the pre-trigger count, the post-trigger scan count,
and the trigger source. The user must determine the triggering requirement based on the nature of the
measurement and the amount of data needed to satisfy the system’s purpose.

• The pre-trigger scan count specifies the number of scans that are to be collected before the trigger
point. If the pre-trigger scan count is greater than zero, the system will continuously collect data
until the trigger is satisfied. If no pre-trigger scans are required, the system sits idle until the trigger;
then, it collects the post-trigger scans before it disarms.
1-10 Signal Management 886995 DBK Option Cards and Modules
Page 43
• The post-trigger scan count specifies the number of scans to be collected after the trigger point.
After the trigger, the post-trigger scans will be collected as programmed and then the system will
disarm itself.
• The trigger source can be a software command, an external TTL input, etc. An analog input
channel on reaching a specified voltage level can be used to trigger the system. (In this mode, an
analog output channel is used to internally set the analog threshold—making it unavailable for other
use.)
Counter/Timer Functions
Counter/timer circuits are used for counting digital events, timing digital pulses, and generating square
waves and pulses. Counter/timer functions are available from the P3 interface.
The table shows the P3 pinout for the 4 counter and 2 timer channels.
Counter/Timer Pins on P3

17 CTR 2 IN Counter 2 input
18 CTR 0 IN Counter 0 input
35 CTR 3 IN Counter 3 input
36 CTR 1 IN Counter 1 input
• IN - a digital input that increments the counter and provides a timebase for counter operation.
• OUT - an output of digital square waves and pulses.
The counter channels can act as 4 independent 16-bit up-counters.
The timer channels are driven by an internal timebase of 1 MHz which can be divided by
1 to 65535 to obtain output frequencies from 15 Hz to 1 MHz.
Simultaneous Sample and Hold (SSH)
Some applications require every channel in a scan group to be read at the same instant, as opposed to
being read with 10 µs between channels. Acquiring multiple readings at the same instant is accomplished
with Simultaneous Sample and Hold (SSH).
An example of an SSH application is as follows. In the example, a performance analysis of an engine
needs to indicate cylinder pressure and temperature, piston strain and position, valve position, and engine
rpm and vibration—all at the same instant. Simultaneous Sample and Hold (SSH) is a means of obtaining
such instantaneous data on multiple channels while avoiding time-skew problems.

Page 44
The previous figure can be used to understand how SSH is used in the DBK17 SSH Card. The process is
(C)
p
C
as follows:
• Input signals pass through an instrumentation amplifier and into a sample-and-hold stage.
• When the sample enable line goes high, each channel’s sample-and-hold stage will “freeze”
the current analog value. The values for all channels are separately “latched” within 50 ns of
each other.
• The signals are held in a stable condition, while the multiplexer switches through all
channels.
• The multiplexer sends the signals [one-by-one] to be digitized by the analog-digital converter
(ADC) in the primary data acquisition device.
• The resulting data is a snapshot of conditions at an instant, but the multiplexing and analog-
to-digital conversion are spread over a longer time interval.
• The simultaneous sample and hold circuit allows you to gather up to 256 simultaneous
samples using sixty-four DBK17s.
Two-Point Calibration of a Temperature Measurement System
Note: In the following text a temperature measurement system consisting of a DaqBook, a DBK19
thermocouple card, and DaqView is referred to. However, it is important to note that the two-point
calibration method can be applied to measurement systems that consist of other acquisition devices
and software.
Overview
Two-point calibration makes use of correction constants
to eliminate offset and gain errors in a temperature
measurement system.
The graph shows an example for a temperature
measuring system, with temperature expressed in
degrees Celsius.
The sensor output is on the horizontal axis and system
response is on the vertical.

• The system has a linear response. Most thermocouple measurement devices have a software
driver, which corrects for the nonlinear output voltage of each thermocouple type. Normally,
there is no provision for linearity adjustment by the user.
• The system has an offset at 0°C, which can be eliminated by introducing an offset correction. This
is the first point of a two-point correction.
• The system has a gain error at 100°C, which can be eliminated by introducing a gain (slope)
correction. This is the second point of a two-point correction.
Suppose you have a temperature measurement system consisting of a DaqBook, a DBK19 thermocouple
card, and DaqView data acquisition software. The DBK19 was shipped with a diskette of calibration
constants. These calibration constants are specific to the DBK19.
1-12 Signal Management 886995 DBK Option Cards and Modules
Page 45
Download instructions for loading the constants into DaqView were inclu ded with the DBK19. The
constants will improve the accuracy of each DBK19 channel when amplifying the thermocouple's millivolt
output, which is read by the DaqBook.
The temperature measurement system, as well as the thermocouple itself, can still have the following types
of errors:
• Thermocouple error (departure from performance of an ideal T/C of that type)
• CJC sensor error (±1°C maximum for the DBK19)
• The DaqBook may have small calibration errors
In some applications, it is possible to ignore these sources of errors and still obtain useful results from the
temperature measurement system. However, the only way to optimize the performance of the system is to
perform an end-to-end calibration. This is done by applying two different temperatures to the thermocouple
connection: one temperature is close to 0°C and the other is at approximately full scale.
Then observe the two corresponding temperature readings in DaqView, and use this information to derive
the values of “m” and “b” in the line slope equation “mx + b.” In this equation, the value of “m” is usually
called the scale, and the value of “b” is usually called the offset. When both the offset and gain correction
values are applied, the system errors are reduced to their lowest level.
An Example of Two-Point Calibration
For illustration, suppose the temperature measurement system consists of a DaqBook/100, DBK19
thermocouple card, and DaqView software. (The following calibration procedure also applies to
temperature measurement systems made up of similar products, but the discussion is simplified with a
specific example.) After setting up the DBK19 card in DaqView as described previously, consider one of
the channels on the DBK19, for example, channel 2. Suppose a type T thermocouple connected to this
channel. In DaqView, select a sampling frequency of 1 Hz and an averaging factor of 200 so that the
readings you get are steady and not fluctuating rapidly.
When you look at this channel in DaqView, the default units are in degrees Celsius. With the acquisition
“off”, click on the cell in DaqView in the Units column for channel 2. You will see an engineerin g units
pull-down menu in a dialog box above the spreadsheet area. Click on the down arrow in this dialog box,
and then select the “mx + b” option. You will note that the default values of scale and offset are m=1 and
b=0 for engineering units of degrees C. These values need to be changed to ones that will give more
accurate temperature readings.
To do this, first place the thermocouple for channel 2 in an environment with a known temperature, for
example an ice bath. Click on the Start All Indicators button in DaqView, and observe the Readings
column for channel 2. Wait until the reading stabilizes, then write down the number in degrees C. Call this
reading the “first actual reading” or RA1, and suppose it is:
RA1 = 2.1°C
Since this reading was supposed to be 0°C, call the first correct reading RC1:
Place the thermocouple for channel 2 in a second known environment. This might be a thermocouple block
calibrator or a fluidized sand bath. In this example, assume that the calibrator has been set to100°C.
Observe the reading in DaqView for channel 2, wait until it stabilizes, then write dow n this number in
degrees Celsius. Call this reading the “second actual reading” or RA2, and suppose it is:
Since the correct second reading was supposed to be 100°C, write down the correct value as:
Stop the monitoring process in DaqView by clicking on the Stop All Indicators button.
RC1 = 0°C
RA2 = 104°C
RC2 = 100°C

Calculation of Scale and Offset
Using the above information, calculate the values of scale (m) and offset (b) that will compensate for the
measurement errors (RA1 and RA2). This is possible because the correct and actual readings are related by
the (mx + b) equations:
RC1 = m(RA1) + b
and
Substituting in the values noted in the above calibration process:
Solving for “m” results in:
Substituting this value of “m” to solve for the value of “b ”:
RC2 = m(RA2) + b
RC1 = m(RA1) + b
0 = m(2.1) + b
RC2 = m(RA2) + b
100 = m(104) + b
100 = m(104 -2.1)
m = 100/(104-2.1) = 0.9814.
0 = 0.9814 (2.1) + b
b = -2.0608.
Implementing the Scale and Offset Constants in DaqView
To implement the scale and offset constants in DaqView, first make sure that the acquisition process is
turned off. Then, click on the cell in the Units column for channel 2. The engineerin g units pull-down
menu above the grid becomes active; click on the down arrow and select the “mx + b” option.
After doing that you have the ability to enter new numbers for m and b. Perform those entries and click on
OK to save them. You can then place the thermocouple back in the ice and fluidized sand baths, observe
the new readings, and note the improvement in their accuracy.
If you want optimum accuracy of all channels in the temperature measurement system, you should perform
the two-point calibration process for each channel.
Converting Degrees from Celsius to Fahrenheit
Once you have performed the two-point calibration process and determined the scale and offset values for
units of degrees Celsius, you can use this information to find the corresponding scale and offset values for
other temperature units. In the previous example, the calibration process produced the following equation
for “mx + b”, using units of degrees Celsius:
To convert to degrees Fahrenheit, use the relationship:
RC (°F) = 1.8 * RC (°C) + 32
Substituting the latter equation into the former yields:
So the new values of m and b are:
These are the scale and offset values that you should enter. Note that RA is still in degrees Celsius since the
raw reading produced by the data acquisition software is in degrees Celsius.

Page 47
One Known Temperature Environment
Suppose that you only have one known temperature environment, such as an ice bath. In this case only one
parameter in the “mx + b” equation can be determined for system calibration. This is called single-point
calibration. Since this is normally the largest source of error, single-point calibration is used to correct the
offset.
Using the same information as in the first example, and supposing that the only actual reading available is
called RA:
Since this reading was supposed to be 0°C, call the correct reading RC:
Substituting these values into the mx + b equation resu lts in:
In a single-point calibration, it is assumed that the value of the scale parameter is completely accurate; that
is, m = 1. Using this information in the above equation results in:
These are the scale (m = 1) and offset (b = -2.1) values that should be entered into DaqView.
RA = 2.1°C
RC = 0°C
RC = 0 = m (2.1) + b
0 = 1(2.1) + b,
b = -2.1
Use of a Temperature Calibrator
Occasionally, it is impractical or difficult to get physical temperature references for system calibration. The
temperature region of interest may be far removed from the example temperatures of 0°C and 100°C.
Accurate temperature baths may not be available.
In these cases, you should use a temperature simulation instrument that lets you dial in your thermocouple
type. The simulator should also let you set the two calibration temperatures that are correct for your
application. The calibrator then generates milli-volt signals into the DBK19 card (or other temperature
measurement product). These signals correspond to those that would be generated, by the chosen
thermocouple types, at the selected temperatures. A disadvantage of this approach is that thermocouple
errors are not corrected or compensated.
For many applications, where the thermocouple is used at lower temperatures, a single-point calibration is
sufficient. In general, thermocouples have little error at 0°C. The thermocouple error tends to increase
linearly as the temperature increases.
CE Compliance
The European Union (EU) first developed CE standards in 1985. The standards include specifications for
safety and for EMI emissions and immunity. Now, all relevant products sold in Europe must meet these
standards.
Although CE compliance is not required in the United States, the standards are often adopted by U.S.
companies since they improve product safety, reduce noise, and minimize ESD problems.
In contracted and in-house testing, most LogBook and Daq device products met the required specifications.
Others were redesigned to meet compliance. In some cases, alternate product versions, shield plates, edge
guards, special connectors, and add-on kits were developed. The section entitled CE Enhancements for Existing Products, which is located at the end of this chapter, includes examples.
CE-compliant products bear the “CE” mark and include a Declaration of Conformity
stating the particular specifications and conditions that apply. Test Records and
supporting documentation that validate compliance are kept on file at the factory.
DBK Option Cards and Modules 886995 Signal Management 1-15
Page 48
CE Standards and Directives
The electromagnetic compatibility (EMC) directives specify two basic requirements:
• The device must not interfere with radio or telecommunications.
• The device must be immune from electromagnetic interference from RF transmitters etc.
The standards are published in the Official Journal of European Union under direction of CENELEC
(European Committee for Electrotechnical Standardization). The specific standards relevant to LogBook
and Daq device equipment are listed on the product’s Declaration of Conformity.
The safety standard that applies to LogBook and Daq device products is EN 61010-1 : 1993 (Safety
Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use, Part 1: General
Requirements). Environmental conditions include the following:
• indoor use
• altitude up to 2000 m
• temperature 5°C to 40°C (41°F to 104°F)
• maximum relative humidity 80% for temperatures up to 31°C (87.8°F) decreasing linearly
to 50% relative humidity at 40°C (104°F)
• mains supply voltage fluctuations not to exceed ±10% of the nominal voltage
• other supply voltage fluctuations as stated by the manufacturer
• transient overvoltage according to installation categories (overvoltage categories) I, II and III.
For mains supply, the minimum and normal category is II.
•pollution degree Ior II in accordance with IEC 664.
For clarification, terms used in some Declarations of Conformity include:
•pollution degree: any addition of foreign matter, solid, liquid or gaseous (ionized gases) that
may produce a reduction of dielectric strength or surface resistivity. A pollution degree I has
no influence on safety and implies: the equipment is at operating temperature with noncondensing humidity conditions; no conductive particles are permitted in the atmosphere;
warm-up time is sufficient to avert any condensation or frost; no hazardous voltages are
applied until completion of the warm-up period. Pollution degree II implies the expectation
of occasional condensation.
Safety Conditions
Users must comply with all relevant safety conditions listed in the Declarations of Conformity and in the
user documentation. This manual, LogBook, and Daq device hardware use the following Warning and
Caution symbols:
(If you see these symbols on a product, carefully read the related information and be alert to the possibility
of personal injury).
LogBook and Daq device products contain no user-serviceable parts; refer all service to qualified
personnel.
•overvoltage (installation) category: classification with limits for transient over-voltage,
dependent on the nominal line voltage to earth. Category I implies signals without high
transient values. Category II applies to typical mains power lines with some transients.
This warning symbol is used in this manual or on the equipment to warn of possible
injury or death from electrical shock under noted conditions.
This warning/caution symbol is used to warn of possible personal injury or
equipment damage under noted conditions.

The specific safety conditions for CE compliance vary by product; but general safety conditions
include:
•The operator must observe all safety cautions and operating conditions specified in the
documentation for all hardware used.
• The host computer and all connected equipment must be CE compliant.
• All power must be off to the device and externally connected equipment before internal access to
the device is permitted.
•Isolation voltage ratings: do not exceed documented voltage limits for power and signal inputs.
All wire insulation and terminal blocks in the system must be rated for the isolation voltage in use.
Voltages above 30 Vrms or ±60 VDC must not be applied if any condensation has formed on the
device.
•Current and power use must not exceed specifications. Do not defeat fuses or other over-current
protection.
Emissions/Immunity Conditions
The specific immunity conditions for CE compliance vary by product; but general immunity conditions
include:
•Cables must be shielded, braid-type with metal-shelled connectors. Input terminal connections are
to be made with shielded wire. The shield should be connected to the chassis ground with the
hardware provided.
• The host computer must be properly grounded.
• In low-level analog applications, some inaccuracy is to be expected when I/O leads are exposed to
RF fields or transients over 3 or 10 V/m as noted on the Declaration of Conformity.
CE Enhancements for Existing Products
This section of describes three CE enhancements.
• DBK41/CE
• Edge Guards for the DBK5, DBK8, and DBK44
• BNC Connectors for CE compliance
Edge Guards for DBK5, DBK8, and DBK44
A plastic barrier attached to the end of a DBK card helps prevent access to leads, and to live circuits.
The edge guards attach to DBKs (see figure below) that are mounted in a DBK41/CE, with EMI shield
plates. The access slot allows insulated wires to pass through the barrier.
DBK Option Cards and Modules 886995 Signal Management 1-17
Page 50
DBK41/CE
The DBK41/CE includes 3 variations of EMI shield plates that attach to the DBK41 enclosure. Besides
acting as an electrical safety barrier, these shields reduce electromagnetic interference (EMI).
Note: The CE kit is included with the DBK41/CE. It can be purchased as an optional accessory for use
with DBK41.
BNC Connectors for CE Compliance
Exposed BNC connectors can receive static charges, which can enter the board’s circuitry, resulting in
ESD damage. To comply with CE standards, BNC connectors must be shielded from high-voltage sources
such as static charges.
Some points:
•Cable and connector requirements are stated in the product’s Declaration of Conformity.
These are typically special coaxial cables with insulated end-connectors and rubber O-rings,
for example, cable kit p/n 418-0800.
• PVC dust caps (p/n CN-96) must cover all unused BNC connectors.
• Properly installed connectors and dust caps will cover the entire surface of the BNC, i.e., no
BNC metal will be exposed.

Overview
Primary data acquisition devices such as DaqBooks and DaqBoards are designed to accommodate a wide
variety of applications. The number of possible system configurations that can be made via the use of DBK
options is staggering.
LogBooks can also be enhanced and expanded with the use of optional DBK cards and modules. In
addition, LogBook systems can incorporate various options that do not fall within the DBK product line.
These LBK options are detailed in the LogBook User’s Manual, p/n 461-0901.
This chapter consists of three pinouts, one or more of which will apply to each specific DBK option. In
many cases the use of a particular pin will vary, depending on the primary data acquisition device being
used. For this reason it is important to look at the pinout of the primary device in its associated user’s
manual. Another reason to look at a specific user’s manual is that you may find additional information, for
example: correlation of a 37-pin connector’s pins to those found on a P4 100-pin connector. In addition,
DB37 connectors for some products are achieved by connecting a cable to an onboard header. Those
headers are not detailed in this DBK Options Manual.
Reference Note: If you plan to use an expansion chassis (e.g., a DBK10, DBK41, orDBK60) for
your data acquisition system, refer to the respective DBK section of this manual for product
details.
Reference Note: For additional information regarding the primary data acquisition devices, their
pinouts and associated software programs, refer to the user’s manual associated with that device.
Reference Note: You must set up your software to accommodate particular DBKs in your
system.

CAUTION
Do not confuse connectors. Ensure that you only connect P1 I/Os to P1,
P2 I/Os to P2, and P3 I/Os to P3. Improper connection may result in equipment
damage.
Turn off power to all devices connected to the system before connecting cables or
setting configuration j umpers and switches. Electrical shock or damage to
equipment can result even under low-voltage conditions.
CAUTION
CAUTION
The discharge of static electricity can damage some electronic components.
Semiconductor devices are especially susceptible to ESD damage. You should
always handle components carefully, and you should never touch connector pins or
circuit components unless you are following ESD guidelines in an appropriate ESD
controlled area. Such guidelines include the use of properly grounded mats and
wrist straps, ESD bags and cartons, and related procedures.

Overview…… 3-1
Setting up Analog DBKs …… 3-4
Setting up Digital DBKs …… 3-6
Setting Internal Clock Speed to 100 kHz …. 3-8
Overview
Most DBK card and module options provide for channel expansion and signal conditioning; however,
some serve as power supplies, and others are no more than interfaces that allow the user to meet desired
connection needs, for example, the use of BNC connectors.
For proper operation with DaqBook or DaqBoard systems, most of the DBK options must be configured,
both physically on the DBK, and in the data acquisition application.
All DBK configuration-related parameters can be found in the DaqView’s Configure System Hardware
screen. “Analog Input” type DBKs will be under the P1 section of the screen, “Digital Input” DBKs will
be under the P2 section, and analog and digital outputs [if applicable] will be under P3.
The following table, in addition to providing a brief description of DBK options, can be used to quickly
identify whether the DBK option is of the P1-Analog or of the P2-Digital type. DBKs that require no
software setup in DaqView are shown in a shaded row and display the comment “No configuration
in DaqView.”

Setting Up Analog DBKs
If you have not already done so, review the applicable individual DBK section to ensure that the DBK
option is physically set as desired. Note that certain DBKs do not require configuration.
Understand your DBK’s physical configuration before attempting to set the device in
DaqView’s Hardware Configuration window. For example, if you were configuring a
DBK45 in DaqView, you would need to know the physical setup of rotary switch SW6
to properly set the address. To expedite the configuration, it is a good idea to have the
identity and setting information ready for each DIP-switch, rotary switch, and jumper,
as applicable.
Reference Note:
If you need to go beyond the basic software setup information that follows, refer to the
DaqView documentation. Note that you can access PDF versions of documents from the
data acquisition CD by using the <View PDFs> button on the CD’s intro page.
Complete the following steps to set up analog DBKs in DaqView.
1. From DaqView’s main screen, pull down the Device menu, and select “Configure Hardware
Settings.”
Selecting Configure Hardware Settings from the Device Pull-down Menu
The Configure System Hardware screen appears, showing the channel assignments.
Configure System Hardware Screen
3-4 DBK Setup in DaqView 968194DBK Option Cards and Modules User’s Manual

The DBKs typically have a channel address set physically on the device, by either a
switch or a header. The channel designated in software must agree with the hardware
setting. Thus, in step 2 below, Channel 0 will only be used to select a specific DBK when
that DBK is physically set for Channel 0. Refer to the specific DBK section for more
information, if needed.
2. Under Analog I/O Option Cards External Connection, select the expansion down-arrow for the
chosen Daq Device channel, for example, P1 Channel 0. A “drop-down” will list the available
analog DBK options.
An alternative to using the expansion down-arrow to access the external connection dropdown list, is to click within the text box. For example, in the following figure, after clicking
on P1 Channel 0’s “Direct Signal Connection” text, the drop-down list appeared.
Configure System Hardware Screen Showing Analog I/O Option Cards,
External Connection, P1 Channel Pull-down List for Channel 0
3. Select the applicable DBK card from the drop-down list.
If the card has jumper or switch setups that need to be set in DaqView, a related window will appear.
Three extracted examples follow: (a) Switch Settings: S1 Sub Address, (b) Switch Settings: SW6
(rotary), and (c) Shunt Settings: JP16 (3-pin shunt).
Examples from Setup Windows
4. Set the software DIP-switch settings, shunt-settings, and so forth to match the hardware settings on the
actual DBK(s).
5. When all the channels and sub-addresses are set correctly, select OK to return to the DaqView main
screen.
6. From DaqView, complete the channel setup, acquisition setup, and data destination setup for each of
the new DBKs.
Reference Note:
If needed, refer to the DaqView documentation for more information. Note that you can
access PDF versions of documents from the data acquisition CD by using the <View
PDFs> button on the CD’s intro page.
This completes the software setup for analog DBK options.

Overview
Most DBK card and module options provide for channel expansion and signal conditioning; however,
some serve as power supplies, and others are no more than interfaces that allow the user to meet desired
connection needs, for example, the use of BNC connectors.
For proper operation with LogBook systems, most of the DBK options must be configured, both physically
on the DBK, and in the LogView program. All DBK configuration-related parameters can be found in the
program’s LogBookHardware Configuration Window, sometimes referred to as a hardware tree. “Analog
Input” type DBKs will be under the P1 branch of the tree, “Digital Input” DBKs will be under the P2
branch, and analog and digital outputs [if applicable] will be under P3.
The following table, in addition to providing a brief description of DBK options, can be used to quickly
identify whether the DBK option is of the P1-Analog or of the P2-Digital type. DBKs that require no
software setup in LogView, or do not apply to LogBook systems are shown in a shaded row and have a
comment regarding the status of “no configuration” or “not used with LogBook.”

SPECIAL CASES – DBK Recognition in LogView for DBK48, 55, 65, and 85
LogView does not include the means to directly select the following DBK options. However, these DBKs will
still function fine with LogBook and LogView. To do so we get the system to recognize these devices by
selecting a different, but related DBK option.
DBK48
16-Slot 8B Signal Conditioning Module
To use a DBK48 and its 8B modules with LogBook: Select DBK42 in LogView. This will recognize the
DBK48, but will identify it as a DBK42. For each 8B module, select the 5B module that exhibits the same
measurement ranges; three examples follow:
For SC-8B30-01 select SC-5B30-01 as both have an Input Range of ±10 mV; and an Output Range of ±5V.
For SC-8B34-02
For SC-8B47-T-07
DBK55
select SC-5B34-02 as both are Type 100 Ohm Pt; with an Input Range of 0°C to +100°C.
select SC-5B47-T-07 as both are a Type T Thermocouple, with an Input Range of 0°C to +200°C.
8-Ch. Frequency to Voltage Input Module
A single DBK55 has the functionality of two DBK7 cards. When using a DBK55 with LogBook, select
DBK7 in LogView. This will recognize the DBK55, but will identify it as a DBK7. Next do one of the
following, as applicable:
(a) If the DBK55 is set to the L sub-address, Select DBK7 (0) and DBK7 (1)
(b) If the DBK55 is set to the H sub-address, Select DBK7 (2) and DBK7 (3)
DBK65
8-Ch. Transducer Interface Module
To use a DBK65 with LogBook: First select DBK80 in LogView. This will recognize the DBK65, but will
identify it as a DBK80 (which has eight additional channels). Next do one of the following as applicable:
(a) If the DBK65 is set to the L sub-address, use channels 0 through 7; and ignore the displayed
unused channels (8 through 15).
(b) If the DBK65 is set to the H sub-address, use channels 8 through 15; and ignore the displayed
unused channels (0 through 7).
DBK85
16-Ch. Differential Voltage Module
To use a DBK85 with LogBook, select DBK80. This will recognize the DBK85, but will identify it as a
DBK80.

Setting-up Analog DBKs
If you have not already done so, review the applicable DBK section to ensure that the DBK option is
physically set as desired. Note that certain DBKs do not require hardware or software configuration.
Understand your DBK’s physical configuration before attempting to set the device in
LogView’s Hardware Configuration window. For example, if you were configuring a
DBK4 in LogView, you would need to know the physical setup of jumpers JP7 and JP8
in order to properly set the Filter Mode for each channel.
Reference Note:
The LogBook User’s Manual (p/n 461-0901) contains a detailed description of LogView,
and should be referred to if you need to go beyond the basic setup information that follows.
Complete the following steps to set up analog DBKs in LogView.
1. Open the LogBook Hardware Configuration Window by clicking the Hardware Configuration
button in LogView’s toolbar. A window similar to the following should appear.
Selecting P1, Analog IO, and a Mode of Single-Ended
2.Select P1, Analog IO and verify that its mode is set to Single-Ended. See preceding figure.
The DBKs typically have a channel address set physically on the device, by either a
switch or a header. The channel designated in software must agree with the hardware
setting. Thus, in step 3 below, Channel 0 will only be used to select a specific DBK when
that DBK is physically set for Channel 0. Refer to the specific DBK section for more
information, if needed.
3. Select an available channel, such as P1_CH00, and assign it to the specific DBK option. As in the
above note, the DBK option’s physical channel must agree with the channel selected in LogView. In
the ongoing example we have selected one DBK4. Up to 8 DBK4s could be selected for P1_CH00.
4-4 DBK Setup in LogView 987693DBK Option Cards and Modules User’s Manual
Page 73
Expanding P1_CH00 with a DBK4
4. Configure the DBK option(s) as applicable for your situation. For example, when configuring
DBK4s, ensure the filter mode (“On” or “Bypass”) agrees with the setup on the actual card(s).
Setting the DBK4 Filter Mode for Channel 0 to Bypass
Note: Setups in software must agree with the physical settings on the DBKs. Refer to the applicable
DBK section for detailed information.
5. Click the OK button to accept the settings.
6. Click the Analog Input button to view the new setup in the Analog Input Channel Configuration
Window. Verify all channel numbers. Assign user labels as desired.
The analog input spreadsheet (see following figure) uses four tabs to group analog
input parameters. Always visible are the Physical Channel, User Label, On/Off, realtime Reading, Range, Units, and Channel Type columns.
Clicking a tab exposes one of the four sub-windows of parameters:
• Storage
• DBK Parameters
• User Scaling
• 2-Point Calibration
If beneficial, adjust column width by placing the cursor on the line between
columns (in the column header) and drag the line left or right as needed; for
example -- to make room for a longer, more descriptive user label.
DBK Option Cards and Modules User’s Manual 987693DBK Setup in LogView 4-5
Page 74
Analog Input Channel Configuration Window
7. From the Analog Input Channel Configuration window, select the DBK Parameters tab to view the
specific settings for each DBK channel.
Some DBKs have settings that are physically set on the hardware via jumpers or
switches. In these cases, the designated parameter settings in LogView must agree
with those on the hardware. Setting one does not automatically set the other; in
other words, you must make configuration settings in both software and hardware,
when applicable. For information regarding DBK hardware configuration, refer to
the specific DBK sections, as applicable.
8. Ensure that the DBK parameters are correctly set at this time. If necessary, refer to the applicable
DBK section for an explanation of the parameters; for example, DBK4 programmable filter values.
You can resize the Analog Input Channel Configuration window by dragging its right
edge further to the right. This allows you to see up to four parameters for each channel.
When possible, use User Label names that closely resemble the Physical Channel
names. This practice makes channel identification easier to remember and helps
avoid confusion.
Example: If Physical Channel P1_CH01 was being used for an alarm, then Alarm-P101
would be a logical User Label.
A note regarding the Range column:
All LogBook channels and many DBK channels have a programmable gain amplifier (PGA) that
provides multiple ranges. Adjusting the range allows you to zoom in or out o n your signal for
maximum signal resolution for the range needed. If the Units and/or Scale (from the User Scaling
tab) are changed, the available ranges are presented in terms of the new units. For example, if a user
scaling of ×20 is applied to a channel to convert volts to PSI (pounds per square inch), the available
range choices for that LogBook channel would be ±200 PSI, ±100 PSI, ±50 PSI, 0-400 PSI, 0-200
PSI, etc.
Some DBKs have hardware switches and jumpers for configuration. When using
such DBKs, corresponding parameters may need to be set in the LogBook Hardware Configuration window.

4-8 DBK Setup in LogView 987693DBK Option Cards and Modules User’s Manual
Please read through this chapter before calling for help. Many customers have solved problems without
factory assistance.
Reference Note:
A list of API error codes appears in the Programmer’s Manual included on your CD-ROM. Note
that API does not apply to LogBook.
Electrostatic Discharge (ESD), Handling Notice
The discharge of static electricity can damage some electronic components. Semiconductor
devices are especially susceptible to ESD damage. You should always handle components
carefully, and you should never touch connector pins or circuit components unless you are
following ESD guidelines in an appropriate ESD controlled area. Such guidelines include the use
of properly grounded mats and wrist straps, ESD bags and cartons, and related procedures.
Troubleshooting Checklist
For most problems, proceed through the following checklist. When applicable, be sure to follow ESD
prevention guidelines to avoid damaging components.
Power. Check power and fuses to all affected units.
1.
If the System Parameters Need Reset. Cycle the power “off” then back “on.” This will often reset
2.
system parameters to the correct values.
Signal. Check signal lines and connectors. Connectors must be free of corrosion. All lines should
3.
be undamaged and free of sharp bends and twists. Signal paths should avoid potential sources of
noise such as high voltage and electromagnetic interference.
Self-Test. Run system diagnostic tests to confirm the LogBook or Daq device is properly connected
4.
to the PC.
Software. Try to acquire data with the DaqView windows application if you are using a Daq device
5.
or LogView windows application if you are using a LogBook. If you are unable to acquire data in
either DaqView or LogView and another program, a hardware problem is likely. If you can obtain
readings by enabling the input reading column, but cannot log data to disk, an interrupt problem is
indicated.
Interrupt. Make sure the interrupt selected matches the interrupt used by the parallel port [for
6.
LogBooks and DaqBooks] or the interrupt selected by the hardware switches [on the DaqBoard].
The program MSD.EXE (comes with DOS 6.0 and later) reports the interrupt usage of the computer.
In some cases, an interrupt conflict may arise due to a Windows printer driver stealing the interrupt.
For such a problem, you must edit the SYSTEM.INI file and remove lines loading the printer
drivers. In other cases, the hardware is incapable of accepting interrupts through the parallel port.
Parallel port. Make sure the parallel port selected is the same as the port to which the LogBook or
7.
DaqBook is connected. Also, make sure the correct protocol is selected. For Daq device users, Daq
device configuration or DaqTest.exe will verify this. Also see Parallel Port Troubleshooting Tips.
DBK Option Cards and Modules 967094Troubleshooting Tips 5-1
Page 78
Software setup. Make sure the device selected in software matches the hardware being used. Verify
8.
that setup parameters are correct for your application and attached DBK cards and modules.
Power management. The POWER.EXE power management program that is used by some notebook
9.
computers is known to affect proper operation of the parallel and PCMCIA ports. If you are having
such trouble, remove the line loading this program from your AUTOEXEC.BAT file.
Device drivers. Some computers are pre-configured for numerous device drivers in their
10.
AUTOEXEC.BAT and CONFIG.SYS files. These drivers often conflict and can be a source of
trouble. It is helpful for diagnostic purposes to boot the machine and test the system with the
minimum number of device drivers loaded.
Parallel Port Troubleshooting Tips
Note: Does not apply to LogBook
After completing the Test Hardware function within the Daq device Configuration control panel applet, if a
connection is not made, try the following troubleshooting tips:
Windows 95/98/Me/2000
1. Check the power supply to make sure power is applied.
2. Check the parallel port cable for tight connections.
3. Try all of the protocols listed in the Daq device Configuration control panel. The parallel port
might have a communication protocol other than standard or normal mode.
4. If you still have not established communications, go to Control Panel, System, Device Manager,
Ports, LPT1 and verify the following:
(a) Under the General and Driver sections, make sure the parallel port is a standard parallel
port with a driver installed and that no resource conflicts are present. If no driver is
installed or resource conflicts are present, you need to resolve these issues with your
computer manufacturer or information services department.
(b) Under the Resource section, make sure the parallel port has an interrupt level assigned.
If not, add one by unchecking the “Use automatic settings” button, selecting “Basic
configuration 0001” so the same base address is maintained but an interrupt level is
added, and double-clicking on the interrupt level so you can add the interrupt level.
Generally, 7 is reserved for parallel ports but pick one to avoid conflicts. Reboot the
computer.
(c) If the parallel port is configured as an ECP parallel port and there are connection
problems, you need to access the BIOS and change the parallel port to a standard or
normal mode. You can generally access the BIOS by pressing F2 or Esc during booting
of the computer. You should see a message “Press F2 to enter setup.” Change the parallel
port mode from ECP to standard or normal. Reboot the computer.
(d) Windows/2000 users:
(1) In the Device Manager’s list, expand “Ports (COM & LPT)”
(2) Highlight “ECP Printer Port (LPT1)” and ‘right-click.’
(3) On the Properties box that appears, select the “Port Settings” Tab.
(4) Select the radio-button option that reads, “Use any interrupt assigned to the port.”

Windows NT
1. Check the power supply to make sure power is applied.
2. Check the parallel port cable for tight connections. Try all of the protocols listed in the Daq device
Configuration control panel. The parallel port might have a communication protocol other than
standard or normal mode.
3. If you still have not established communications, go to Control Panel, Devices, Hardware Profiles,
Parallel Port and verify the parallel port drivers are installed. If the dr ivers are not installed, you
need to resolve this with your computer manufacturer. Also, check that the parallel port has an
interrupt level assigned to it by looking at the parallel port resources in the Daq device
Configuration control panel.
4. If it is necessary to add an interrupt level or to change the parallel port communication port, you
need to access the BIOS during computer booting. You should see a message that reads similar to
“Press F2 to enter setup.” If the parallel port is configured for ECP or EPP, change it to standard
or normal; then reboot the computer.
Frequently Asked Questions Note: Most of these questions pertain to older devices.
Q: What are the input and output signal levels on P2 and P3?
A: P2 and P3 are TTL compatible with high levels no greater than 5 volts and low signals at 0 volts or
ground.
Q: What DBK options require the SSH jumper on JP2 to operate?
A: The SSH jumper must be installed on DaqBook/100 Series devices, DaqBook/200 Series devices and
ISA-Type DaqBoards to operate the following DBK options: DBK2, DBK4, DBK5, DBK7, DBK17,
DBK45, DBK50 and DBK51. Daq PC Cards do not have a JP2, but will operate these cards as long as
power for these cards is available.
Q: How do I set a DaqBook/112 to measure single-ended vs differential analog input signals?
A: DaqBook/100, DaqBook/112, and DaqBook/120 models are set by JP4's position. DaqBook/200,
DaqBook/216, and all DaqBoard models and Daq PC Cards are set by software commands.
All Daq devices must be set to single ended mode in order for DBK options to operate.
Q: How do I set a DaqBook/100 device to measure bipolar (+5v to -5v) instead of unipolar (0 to 10v)
analog input signals?
A: DaqBook/100, DaqBook /112, and DaqBook /120 models are set by JP3's position and are unable to
mix bipolar and unipolar input signals (unless using a DBK15 option). DaqBook/200, DaqBook /216,
all DaqBoard models and Daq PC Cards are set by software commands and are able to mix bipolar and
unipolar inputs by channel.
Q: I am trying to measure differential signals, but my Daq device is not reading the signal correctly.
What could be wrong?
A: The Daq device must be configured to measure differential signals. Differential signals are measured by
reading the signal at the high input with respect to common and then subtract the signal at the low input
with respect to common. In addition, common must be connected at the Daq device in order to measure
the differential signal accurately. If the signal being measured only has 2 wires, connect a 100 KΩ
resistor between low and common to provide a reference.

Q: I can read analog inputs at the primary Daq device, but my ISA-type DBK option card doesn’t
work. What could be wrong?
A: The analog DBK cards require power to operate. This power can be provided by the DaqBook or ISA-
type DaqBoard (via JP1), DBK32A, or a DBK33. The following voltages [with respect to P1’s pin 7]
must be present to power up analog DBK option cards:
• +15 volts on P1, pin 21
• -15 volts on P1, pin 2
• +5 volts on P1, pin 1
Note: Daq PC Cards do not have power available. If all power is present, there could be a failure in the
DBK option or the Daq device. If the first channel of the DBK option can be read, but other
channels cannot, then the failure is in the primary Daq device.
Q: How does the Daq P1 expansion bus work?
A: All Daq products have 16 single-ended analog inputs. Each of these analog inputs can be expanded to
16 additional inputs with DBK options, providing up to 256 analog inputs. The primary Daq device uses
4 digital output lines on P1 to multiplex the DBK option channels through each analog input of the Daq
device.
Channel numbers on the Daq device are numbered 0 through 15; and expansion channels are numbered
16 through 271. Since each Daq channel can have up to 16 option channels, multiple DBK options that
have 2, 4, or 8 channels can be multiplexed through one primary Daq device channel.
Q: How do I get analog outputs, other than the 0 to 5 volt analog outputs, from my DaqBook/100
Series device, DaqBook/200 Series device, or my ISA-type Daq device?
A: DaqBook/100 Series, DaqBook/200 Series, and ISA-type DaqBoard device analog outputs (12 bit D/A
converters) are 0 to 5 volts using the internal -5 volt reference. For different or higher analog output
ranges (-10 to +10 volts max), you must provide and external reference voltage equal to the maximum
analog output value desired times -1 (-10 volts for 0 - 10 volt range).
This reference voltage must be applied to pin 10 for D/A channel 0 and pin 26 for D/A channel 1 with
respect to pin 28 or 29 on P1. JP2 on the Daq device must be set to DAC EXT for each channel used.
You cannot use the SSH line for smart DBK options (DBK2, DBK4, DBK5, DBK7, DBK17, DBK45,
DBK50 and DBK51) when using an external reference on D/A channel 1.
Failure to remove the SSH jumper on JP2 when applying an external reference voltage to D/A
channel 1 (pin 26) will result in damage to the Daq device.
Note: Daq PC-Cards do not have analog outputs.
Q: My computer uses ECP is that the same as EPP?
A: No. ECP (Enhanced Computer Port) is a different protocol than EPP (Enhanced Parallel Port).
• ECP will function with DaqBooks.
• ECP will function with LogBooks.
• ECP will work with WaveBooks only if,
(a) the WaveBook has a 262-0301 rev b or later chip. Note that chip upgrades are available.
(b) the version of WaveView being used is higher than version 7.8.
Q: I cannot find where the software settings for the DBK7 and the DBK4 cards are located in
DaqView. Where do I find these?
A: After selecting a DBK4 or DBK7 card in "Configure Hardware Settings," a dialog box appears that
allows you to select the number of cards and the sub address settings. There is a <Config> button in
the lower right hand corner. After clicking on the <Config> button the software settings for these
cards can be set.

Q: The DBK4 seems to kill my system. When the DBK4 is removed, the system functions properly.
Does this imply that the DBK4 is defective?
A: More often than not this indicates a lack of available power. The most common symptom of low
power is a "dead" unit. Failure to provide adequate power can damage one or more components in
your system, but more frequently, the system simply won’t work.
It is important that you calculate your system's power demand before connecting the DBK4, as you
may need an auxiliary power supply. Each DBK4 draws 2750 mW, which is high in comparison to
the power drawn by other DBK cards. As can be seen in the following table, when using a
DaqBook/100 Series product you will always need additional power, while other systems can typically
power at least one DBK4 card.
Reference Note:
Refer to Power Management in the DBK Basics section, located near the front of the
manual, for more information on calculating the system power demand for all your DBK
cards.

Q: How do I calculate the total amount of power needed for all my DBK options?
A: You can calculate your power needs with the tables in Power Management, in the DBK Basics section
located near the front of this manual.
Q: The CA-134 cable does not work with my Daq PC-Card. Why not?
A: Daq PC-Cards Daq/112B and Daq/216B that have a serial number equal to or greater than S/N 151044
use cable CA-134. This cable’s latching connector does not work with the older PC-cards.
Daq PC-Cards Daq/112B and Daq/216B that have a serial number preceding 151044 require cable
CA-134Q.
Q: I cannot read signals with the DBK12 or DBK13. What could be wrong?
To measure single-ended signals with the DBK12 and DBK13:
A:
1) the JP3 jumper on those boards must be set to SE (Single Ended)
2) the signal must be connected to the analog input High terminal and Common.
When measuring SE signals, the Low input is ignored.
To measure differential signals with the DBK12 and DBK13:
1) the JP3 jumper on those boards must be set to DIFF (Differential)
2) the signals must be connected to the High, Low, and Common input terminals.
If only 2 wires exist for your signal, connect them to the High and Low inputs and install a 1K ohm
resistor between the Low and Common [in the area between the terminal strips and the electronics] on
the DBK12 or DBK13. The place to install the resistor is labeled by channel number and is designated
by the letter "L." The letter "H" designates where to install a resistor between the high and common
terminals if balanced inputs are desired.
Note: Cards are presently manufactured with 100K ohm resistors installed in the "L" locations.
Q: My DIP switch settings appear to be giving my DBK card an incorrect address.
A: There have been a few instances in which a DBK modification included replacing one type of DIP
switch with another; for example, replacing a slide-type switch with a rocker-type switch or a toggletype switch. Although the actual setting of “0” and “1” values remains unchanged for configuring an
address, using a “toggle-Type” switch diagram for a “Slide-switch” results in what looks like an
opposite setting, i.e., 0-0-0-0 would look like 1-1-1-1 if the diagram was not replaced.
The following example may help you determine if you have a “0 / 1” DIP switch reversal:
Example:
If you have a 4 micro-switch DIP switch, an address of zero would require 0-0-0-0. Thus, regardless
of what your diagram may look like, the following holds true:
For a slide-type switch… the slides would all be toward “0.”
For a toggle-type switch… the depressed part of the switch would be at “0.”
For a rocker-type switch … the rocker-arm (like a standard light switch) would be toward the “0.”
Please contact the factory if you believe your DIP switch documentation is incorrect.
