Hardware Connection

The following hardware-connection figure and procedure are generic; details vary with system complexity.

LogBook/300 System, Basic Connections

Note:

There are two styles of LogBook/300. The earlier version’s PC-Card door is hinged on the right edge. The newer model,

represented in the figure, is hinged on the lower edge.

LogBook User’s Manual,

8-17-99

Quick Start, LogBook/300 QS-300-1

After verifying that all equipment power is off, hardware connection typically proceeds as follows.
Refer to the previous figure as needed.

1. Connect LogBook to PC. There are three ways for LogBook to communicate with the host PC.
These are: parallel port, serial port, or by physical transportation of the PC-Card. Note that the
parallel port method is represented in the previous figure.

Parallel port – If using the parallel port, connect the supplied 2-foot parallel port (DB25) cable

a)

to PARALLEL PORT on LogBook, and to the corresponding parallel port on the PC. When this
method is used, the PC must be set to the ECP mode. See ECP Parallel Port, page 4 for
additional information.

Serial port – If using the serial port, connect the supplied 6-foot serial-port (DB9) cable to

b)

SERIAL PORT on LogBook, and to the corresponding serial port on the PC.

c) PC-Card - As described chapter 1’s PC-Card Swapping section, LogBook does not require an

electrical connection to the PC. The PC-Card must be pre-configured [from LogView on the PC]
to contain the desired configuration file. Then the PC-Card is inserted into the corresponding
slot behind the door on the LogBook’s front panel.

2. Connect the LogBook to the DBK cards and modules. Most of the analog DBKs connect to P1 on
the rear panel; the digital DBKs generally connect to P2—refer to documentation for your particular
DBKs in chapter 5 and for general DBK installation details. The CA-37-x cable can daisy-chain
several DBKs including the DBK41, which has a built-in P1 bus connection for 10 DBK cards.
The x in the cable part number refers to the number of devices that can be connected (a CA-37-1
cable actually has two DB-37 connectors). The P1/P2 pinouts are included in chapter 1. Observe the
input signal strength limitation as cautioned below—especially if using a non-DBK source.

For analog signal inputs via P1, do not exceed -35 VDC or +45 VDC.
Exceeding these limits could result in equipment damage.

3. Connect DBK(s) to transducer(s). Follow instructions for particular DBK as described in chapter 5
and for the particular transducer. Some DBKs can accommodate both BNC and screw-terminal
connections.

4. Connect LogBook to a suitable power source. The easiest
connection is to use the TR-43 AC-to-DC power source or the
DBK34. DC power sources such as a car batteries, etc must
supply 10 to 45 VDC and use the correct DIN5 pinout (see
figure). A locking DIN5 connector assures a secure power
connection for applications subject to vibration or thermal stress.

5. (optional) Just one cable connects between the LBK1 (via RJ-11 connector) and the LogBook (via a
DB9 connector). The standard cable is 6 ft long, and an optional cable is 25 ft long (see chapter 4 for
LBK1 installation details).

Hardware Configuration

Reference Notes:

(1) Refer to chapter 4 in regard to the various LBK options.
(2) Some DBKs require manual configuration. Refer to chapter 5 for specific DBK

information.
LogBook's top cover does not need to be removed, except to add or remove an LBK option, or to replace
the fuse.

&$87,21

Most LogBook configuration is done via software as described in section, LogBook/300 Device
Configuration. Except when using the RS-485 communication option, LogBook configuration does not

require you to set jumpers or switches.

QS-300-2 Quick Start, LogBook/300,

LogBook User’s Manual

Software Installation

Note: The LogBook is supported under Windows95/98 and WindowsNT. Your computer should be a

486 or higher (Pentium

®

recommended) with at least 16 Mbytes of RAM. 32 Mbytes of RAM is

recommended.

Note: Before installing software, ensure LogBook is connected to the selected port

(serial, or ECP-parallel); and power-on the system.

Install installation CD-ROM (or installation disks, as applicable). Run the Setup.exe and follow screen
prompts.

When the software installation is complete, you will be given two options:

•

Exit running the configuration utility—if the LogBook is to be used immediately.

•

Exit and return to operating system—you can run the configuration later from the control panel.

LogBook/300 Device Configuration

A configuration utility is supplied via a control panel applet. The LogBook Configuration applet allows
you to add a device, remove a device, or change existing configuration settings. From this same window,
you can also access a built-in utility to test the connected device for current setup and performance.

LogBook Configuration can be found in the Windows95/98/NT control panel. This can be navigated to
from Window’s desktop Start button:

Start ⇒ Settings ⇒ Control Panel

You can enter LogBook Configuration during driver installation or whenever you wish to add, remove or
change device configuration settings. The following description applies to either method.

st

The 1

configuration window will display configured devices in the Device Inventory field based on the
port they’re connected to. Devices are indicated by their name and icon. If no devices are currently
configured, no devices will appear in this field. (The figure shows the 1
overlapping.)

Properties. Configuration settings for a device can be changed or modified from the corresponding
properties window. To do so, double-click the device icon or single-click the device and then single­click the Properties button. The 2

nd

configuration window will appear for the selected device as

shown in the previous figure.
Add. The Add Device button is used to add a device configuration whenever a new device is added
to the system. LogView cannot recognize a device unless listed in the configuration window.
Remove. The Remove button is used to remove a device from the configuration. A device may be
removed if it is no longer installed or if the device’s configuration no longer applies.

Close. The Close button may be used at any time to exit the LogBook Configuration applet.

Device Name is displayed with the default name, numbered successively as configured. This field

can be changed to any descriptive name as desired.

Connection Type can be serial or parallel port.
Device Connection specifies the port name.
Protocol is used to set the parallel port protocol (ECP only) or serial protocol (RS-232 or RS-485).
Device Timeout specifies the number of seconds LogView will be wait for a LogBook response

before displaying an error condition.

To use parallel port communication with an attached LogBook, your PC must support
the ECP protocol AND be set in the ECP mode.

Serial Port

PCs made since 1994 probably support the Enhanced Computer Port protocol (ECP). If your parallel port
does not support ECP, you can communicate with the LogBook via the RS-232 serial port, or you can add
an ECP-compatible ISA board or PC-Card parallel port. Setting the PC to ECP mode varies with different
computers. On some computers, you can enter the BIOS Setup utility from Windows Settings or during
startup by pressing the F1 function key. The Parallel Port Mode property can be found under the Peripheral
Configuration group menu item. If necessary, consult your PC’s documentation or your PC’s manufacturer.

To ensure ECP compatibility after proper setup, use the Test Hardware utility
(described on page 5). Before testing, make sure LogBook is properly connected,
powered on, and that the Parallel Port Mode is set to ECP (in BIOS Setup).

&$87,21

Making errors in BIOS Setup can disrupt your system’s operation. If test hardware
indicates a problem and you have inadequate experience with the BIOS Setup utility,
consult your System Administrator or other qualified individual.

If the selected device is connected to a serial port the properties window will include the fields shown in the
figure at right. Baud rate can be set from 1200 to 115200 bits per second (default 9600). When all fields
have been changed to the desired settings, you can click on one of the following options:

•

Apply to store the device configuration. Parameters are not locked in until you click the Apply
button. If you make changes and don’t click Apply, clicking the Test button in Test Hardware will
yield unexpected errors.

•

OK to store the configuration and exit the current property screen.

•

Cancel to exit the current screen without storing any changes.

•

Test Hardware to test the current device.

LogBook User’s Manual

Test Hardware

Before testing LogBook/300:

(a) Verify the device has been properly installed

(b) Make sure the communication cable (serial or parallel) is firmly in place to the proper ports.

(c) Verify the device is powered-on.

To begin the test, click the Test button. Test results should be displayed within a few seconds.

Test results indicate if the device is online (properly connected, powered on and ready to transfer the data)
or offline. If the device is online, Performance Test will display Download and Upload speed rates. These
rates represent the maximum speed at which downloading and uploading files can be performed. Actual
transfer time will depend on channel configuration and the size of the transfer.

LogBook Properties Tab Test Hardware Tab

Testing the LogBook device might cause the system to hang. If test results are not
displayed within 30 seconds, or if the system does not respond properly: reboot the
system. Upon power-up, re-enter the LogBook Configuration and ensure the LogBook
configuration settings are correct. Change the settings as applicable.

Acquisition Configuration

An acquisition is configured using LogView on a PC and then stored as an acquisition setup file on a
PC-Card. The PC-Card may be in an attached LogBook or in the PC to be later manually transferred to an
unattached LogBook. The system’s DBK cards are listed; the scan sequence is defined; the trigger
conditions are specified, etc.

Reference Note: Configuring the acquisition is described in chapter 3, LogView.

LogBook User’s Manual,

8-17-99

Quick Start, LogBook/300 QS-300-5

Calibration

Calibration is typically performed automatically through LogView software; however, some DBKs may
require manual calibration. LogView’s 2-point calibration fine-tunes the reading’s slope and offset error
(mx+b). DBKs working with non-linear sensors typically condition/convert the reading to a linear form.
Otherwise, a non-linear analog input signal is difficult to read accurately. Careful use of the calculated
channels may yield usable approximations in simple, limited-range conditions.

Reference Note: An example of 2-point calibration is given in the How To… section of
chapter 3, LogView.

Appendix A details the calibration methods applicable to DBK16 and DBK43.

3 – Remove card drawer.

A. Remove the two screws that hold the card drawer to the chassis.
B. Loosen the three termination panel thumbscrews.
C. Carefully pull the card drawer free of the chassis.

4 – Remove termination panels.

For each termination panel, remove the two screws that mount it to the card drawer, then remove the
termination panel.

5 – Determine power requirements.

Depending on the power needs of your system’s DBK cards, you may need to add a power card.
Refer to Chapter 2, System Power, in regard to calculating your power requirement.

If the required power is more than the available power (see chapter 2 for calculations), your system will
require auxiliary power. One of two power supply cards can be used with LogBook:

•

DBK32A – For use with a LogBook, DaqBook, or DaqBoard. It supplies ±15 V.

•

DBK33 – For use with Log Book, DaqBook, DaqBoard, or Daq PC-Card. It supplies +5 V and ±15 V.

6 – Configure chassis for power sources.

Proper jumper configuration limits LogBook’s P1 bus to one power source. The P1 bus should never have more
than one power source.

The JP1 and JP2 jumpers located on the P1 Interconnect Board inside chassis (see previous figure) control the
+5V distribution. Both the JP1 and JP2 jumpers are installed as factory-default.

JP2

A.

.

Only remove the JP2 jumper if cards (on the internal P1 bus) are to be powered from LogBook’s

internal PCB.

JP1

B.

.

Only remove the JP1 jumper if a DBK33 is used with the system.

7 – Install power card if necessary.

If you determined in step 5 that additional power was needed, add a DBK32A or DBK33 power card to the
chassis. Chapter 2 includes information regarding these power-related cards.

A. Carefully align the power card’s DB37 connector with a DB37 connector on the interconnect board and

gently press them together.

B. Mount the power card with two screws into the standoffs on the card drawer.

8 – Configure LogBook/360.

Refer to chapter 1. Note that if a LogBook/360 driver is not available in software, select LogBook/300.

9 – Configure DBK cards.

Configure unique channel addresses with the jumpers on the DBK cards. Some cards have other jumpers and/or
DIP switches. Refer to the particular DBK sections of Chapter 5, as needed.

10 – Install DBK cards.

You must use all analog DBK cards in the LogBook/360; unless you have a factory modification that allows the
use of all digital cards. You can not use both analog and digital cards at the same time.

Connect LogBook/360 to PC, External DBKs, and Power*

The following hardware-connection figure and procedure are generic; details vary with system complexity. For
“unattached mode,” a pre-configured PC-Card is inserted in the PC-Card slot, and no connection to a PC is made.
The following figure illustrates the “attached” mode.

*Note: Connecting LogBook/360 to a PC applies to the “attached mode” only. Many applications will make use of

three internal DBK cards only, having no need to attach external DBK cards or modules as discussed in the
following text.

After verifying that all equipment power is off, hardware connection typically proceeds as follows.
Refer to the above figure as needed.

1. Connect LogBook to PC. There are three ways for LogBook to communicate with the host PC.

LogBook User’s Manual,

LogBook/360 System, “Attached Mode,” Basic Connections

Note:

Rear panel connections may be made via terminal blocks, as discussed in the previous section,

Card Drawer Setup

.

These are: parallel port, serial port, or by physical transportation of the PC-Card. Note that the
parallel port method is represented in the previous figure.

a) Parallel port – If using the parallel port, connect the supplied 2-foot parallel port (DB25) cable

to PARALLEL PORT on LogBook, and to the corresponding parallel port on the PC. When this
method is used, the PC must be set to the ECP mode. See

ECP Parallel Port

, page 8 for

additional information.

b) Serial port – If using the serial port, connect the supplied 6-foot serial-port (DB9) cable to

SERIAL PORT on LogBook, and to the corresponding serial port on the PC.

c) PC-Card - As described chapter 1’s

PC-Card Swapping

section, LogBook does not require an
electrical connection to the PC. The PC-Card must be pre-configured [from LogView on the PC]
to contain the desired configuration file. Then the PC-Card is inserted into the corresponding
slot behind the door on the LogBook’s front panel.

Quick Start, LogBook/360 QS-360-5

2. Connect LogBook to the DBK cards and modules. For connecting internal DBK cards, refer to the
earlier section entitled, Card Drawer Setup.

Most analog DBKs connect to P1; digital DBKs generally connect to P2. Refer to chapter 5 for your
particular DBKs and for general DBK installation details.

The CA-37-x cable can daisy-chain several DBKs including the DBK41, which has a built-in P1 bus
connection for 10 DBK cards. The x in the cable part number refers to the number of devices that
can be connected (a CA-37-1 actually has two DB-37 connectors).

Note: Chapter 1 includes LogBook P1, P2, and P3 Pinouts.

&$87,21

For analog signal inputs via P1, do not exceed -35 VDC or +45 VDC.
Exceeding these limits could result in equipment damage.

3. Connect DBK(s) to transducer(s). Follow instructions for particular DBK as described in chapter 5
and for the particular transducer. Some DBKs can accommodate both BNC and screw-terminal
connections.

4. Connect LogBook to a suitable power source, such as a
TR-43 AC-to-DC power adaptor or DBK34 vehicle UPS
module. DC power sources such as a car batteries must
supply 10 to 45 VDC and use the correct DIN5 pinout
(see figure). A locking DIN5 connector assures a secure
power connection for applications subject to vibration and
thermal stress.

ECP Parallel Port

PCs made since 1994 probably support the Enhanced Computer Port protocol (ECP). If your parallel port
does not support ECP, you can communicate with the LogBook via the RS-232 serial port, or you can add
an ECP-compatible ISA board or PC-Card parallel port. Setting the PC to ECP mode varies with different
computers. On some computers, you can enter the BIOS Setup utility from Windows Settings or during
startup by pressing the F1 function key. The Parallel Port Mode property can be found under the Peripheral
Configuration group menu item. If necessary, consult your PC’s documentation or your PC’s manufacturer.

Serial Port

If the selected device is connected to a serial port the properties window will include the fields shown in the

Test Hardware

Before testing LogBook/360:

(a) Verify the device has been properly installed

(b) Make sure the communication cable (serial or parallel) is firmly in place to the proper ports.

(c) Verify the device is powered-on.

Testing the LogBook device might cause the system to hang. If test results are not
displayed within 30 seconds, or if the system does not respond properly: reboot the
system. Upon power-up, re-enter the LogBook Configuration and ensure the LogBook
configuration settings are correct. Change the settings as applicable.

To begin the test, click the Test button. Test results should be displayed within a few seconds.

Test results indicate if the device is online (properly connected, powered on and ready to transfer the data)
or offline. If the device is online, Performance Test will display Download and Upload speed rates. These
rates represent the maximum speed at which downloading and uploading files can be performed. Actual
transfer time will depend on channel configuration and the size of the transfer.

Acquisition Configuration

An acquisition is configured using LogView on a PC and then stored as an acquisition setup file on a
PC-Card. The PC-Card may be in an attached LogBook or in the PC to be later manually transferred to an
unattached LogBook. The system’s DBK cards are listed; the scan sequence is defined; the trigger
conditions are specified, etc.

Calibration

Reference Note: Configuring the acquisition is described in chapter 3, LogView.

Calibration is typically performed automatically through LogView software; however, some DBKs may
require manual calibration. LogView’s 2-point calibration fine-tunes the reading’s slope and offset error
(mx+b). DBKs working with non-linear sensors typically condition/convert the reading to a linear form.
Otherwise, a non-linear analog input signal is difficult to read accurately. Careful use of the calculated
channels may yield usable approximations in simple, limited-range conditions.

Reference Note: An example of 2-point calibration is given in the How To… section of
chapter 3, LogView.

Appendix A details the calibration methods applicable to DBK16 and DBK43.

Introduction

LogBook/300 and LogBook/360 are PC-based data acquisition systems that can work in a stand-alone
mode (no PC present), or linked to a PC. They combine onboard intelligence with a removable PC-Card

that stores the configuration file and the collected data. LogBooks have many options, most of which are
detailed in the LBK and DBK chapters. The PC link can be by serial or parallel port.

LogBook/300, Simple System Setup

The PC-Card holds the configuration file [created by LogView]. The file tells LogBook how to perform a
particular acquisition. The PC-Card also holds the acquired data files. The PC can upload to or download
from the PC-Card by cable if the PC is attached to LogBook, or by physical transport of the PC-Card from
one unit to the other. Multiple configuration files and multiple PC-Cards allow the system to handle
complex data acquisition environments with a large number of data-files.

LogBook/360, as noted.

•

Removable PC-Card. A 12-520 MB capacity holds the software, operating system, user
configurations and the acquired data. The PC-Card is at the center of LogBook operations.
A PC-Card [pre-programmed by LogView] ensures an unattached LogBook comes up properly.

•

Power Supply. The internal power supply accepts an input of 10 to 45 VDC and supplies filtered
regulated voltages to its internal circuits and to accessories connected via P1/2/3. An external AC
adapter for all standard voltages is included with the system.

•

System Controller. A microprocessor chip is used within LogBook with either 4 MB (standard) of
RAM or 16 MB (optional). A field-upgradeable 512 KB Flash memory is used to store the system
startup code, self-diagnostics, and FPGA configuration.

•

Analog Input via P1. 16 main channels that can each accommodate 16 sub-channels via
multiplexing for a total of 256 analog input channels. Fault protection and buffer circuits prevent
overloads and cross-channel noise due to impedance mismatch.

•

•

Computer/Control/I/O – Includes: PARALLEL PORT (ECP Mode), SERIAL PORT (for RS-232
or RS-422/485), TERMINAL PORT (for LBK1 LogBook Remote Terminal option). In addition, for
LogBook/360 only, there is a COM Expansion Card with two serial ports (SERIAL AUX and
SERIAL GPS). These two ports are for connecting auxiliary serial devices, such as a Global
Positioning System.

System Software

LogBook software includes LogView, Upload Scheduler (optional), DIAdem-View, and PostView.
LogView and the Upload Scheduler are detailed in Chapters 3 and 4, respectively. DIAdem-View is

discussed in it’s own, separate user documentation. Appendix F covers PostView, which is similar to
DIAdem-View, but much more limited. Each of these programs is discussed briefly below.

•

•

•

•

LogView is a ready-to-use Windows program for data acquisition and logging. The program
provides a means of selecting channels, gains, transducer types, and various parameters. After setting
up the configuration on the PC, you must download the configuration file to LogBook’s PC-Card.
LogBook then uses the PC-Card to start the pre-configured acquisition. During an acquisition,
LogView can display channel values in a spreadsheet, bargraph, analog meter, or digital indicator.
LogBook data can be uploaded to your PC in various data formats (Excel™, SnapMaster™,
MATLAB™, DASYLab™, Lotus

®

, Quattro, and ASCII) for compatibility with virtually all

post-acquisition analysis software. LogView is detailed in chapter 3.
DIAdem-View provides a means of viewing and analyzing data via interactive graphics. The basic
DIAdem-View can be enhanced with optional software modules. Refer to the separate DIAdem

User’s Manual and the DIAdem on-line help for detailed information.
PostView is a post-acquisition waveform-display program. The program permits the simultaneous

viewing of up to 16 pre-recorded data channels. PostView allows you to expand, contract and
auto-scale waveforms, and scroll forward or backward on the time line. PostView is detailed in
Appendix F.

Upload Scheduler is an application that exists as part of the LogBook/Modem option. Upload
Scheduler allows you to configure upload events for one or more LogBooks. A scheduled event can

be configured to execute one time, or periodically, with no post-configuration intervention by the
user.
The Upload Scheduler is detailed in chapter 4.

PC-Card Swapping

After the initial setup, you can interact with LogBook with PC-Cards. A safe-swap LED (inside the
PC-Card access door) lights when it is safe to change PC-Cards. You can also interact with LogBook using
the LBK1 Remote Terminal Panel option (discussed in chapter 4). The LBK1 option provides limited
LogBook control without use of the LogView program.

Note: during operation, LogView is the primary system interface for control and configuration.

You can change PC-Cards to load setup files, replace full cards, or transport data to an unattached PC.
When the PC-Card door is opened, a detector starts a preparatory routine to clean up files on the installed
disk. Within a few seconds, a green LED indicates it is safe to swap PC-Cards. Swapping should be done
quickly to prevent gaps in the recorded data. 4 MB RAM provides about
10 seconds at 100 kHz and 1.75 minutes at 10 kHz. 16 MB RAM provides over a minute at 100 kHz and
about 12 minutes at 10 kHz for one-channel scans.

System Considerations 1-7

Power Supply

Power Input Connector

Internal Power Supply

AC-to-DC Adapter

UPS

LogBook’s front panel has a socket DIN5 connector to access power
(10 to 45 VDC at 0.3 to 7.0 A). The included AC-to-DC adapter
(TR-43) is recommended. However, various power supplies if properly
wired (see figure) can be used.

LogBook’s power supply is a switching design (pulse-width modulated). The input will accept 10-45 VDC
with a current range of 0.4 to 7.0 A. The input is protected by an 8 A fast-blow fuse. The fuse will open if
the input voltage is applied with the wrong polarity.

The power supply provides the necessary voltages to P1, P2, and P3 for use by DBKs. You can refer to the
P1, P2, and P3 pinouts (in this chapter) and to chapter 2, System Power, for detailed information.

An AC-to-DC adapter (TR-43) is provided with LogBook. This external, switching supply runs on
US/Europe/Japan input voltage ranges. Output voltage and power are sufficient to run the system in most
applications. Input: 90-260 V @ 50-60 Hz. Output: 15 VDC @ 2.3 A. If more power is needed, a
24 VDC, 2.2 A adapter (TR-44) is available as an option.

DBK34 is an optional uninterruptable Power Supply (UPS) that allows LogBook to operate for at least
30 minutes without any other source of power. This capability allows operation, for example, during
starting and after switch-off of an automobile. Control circuits keep the on-board batteries fully charged
when possible. For more information on the DBK34, refer to chapter 2, System Power.

Power Failure and Recovery

When power fails, LogBook preserves as much data as possible. LogBook also attempts to keep PC-Card
file formats and structures intact. Due disk drive latencies, power-supply limitations, and DOS file
structure, it may not be possible to finish the shutdown process before a complete loss of power occurs.

Note: Recovery will not occur when power is restored, unless the shutdown process was completed.

Note: The DBK34 Vehicle UPS is recommended for applications that are subject to power problems,

or are intolerant to down time. DBK34 is discussed in chapter 2, System Power.

Microprocessor

LogBook uses a high-integration microprocessor with up to 16 MB of memory (4 MB standard). The
microprocessor and a Field-Programmable Gate Array (FPGA) control all LogBook operations including
real-time control. Internal flash memory is used instead of EPROMs. This allows for field upgrades of
virtually all functions, including FPGA circuitry. Most software will be read from the disk drive.

Field-Installation Racks and Enclosures

A special rack (p/n Mount1) is available to attach the LBK1 (Remote Terminal Panel option) to the top of
LogBook. The LBK1 section of chapter 4 provides details. For applications in harsh environments, a

P1, P2, P3 Port Connectors

LogBooks have three port connectors: P1, P2, and P3. For LogBook/300, these connectors are located on
the rear panel. For LogBook/360, they are on the front panel (see note). Connector pinouts begin on the
following page.

Note: LogBook/360 actually has two sets of these connectors, one set on the motherboard, and one on the

front panel. LogBook/360’s front panel P1, P2, and P3 connect to the motherboard P1, P2, and P3
via ribbon cables.

P1 (Analog Input)

LogBook’s P1 connector is compatible with all DBK options. Features and capabilities of P1 signals
include:

•

High-performance signal connection for: ±10 V and 0-20 V input ranges, gains from ×1 to ×64 (each
gain and range calibrated individually), and an input stage with low crosstalk, high dynamic
impedance, small signal injection.

•

All calibration is performed digitally; there are no pots to adjust.

•

The sequencer depth (the number of channel readings in a scan) is 1024 analog channels and 128
digital channels.

•

P1 includes an enhanced DBK-50 protocol that allows DBK cards or modules to identify themselves
and carry their own calibration data. These same connections can allow complete configuration of
DBK cards with that capability (allowing them to be jumperless).

For analog signal inputs via P1, do not exceed -35 VDC or +45 VDC or
equipment damage may result.

&$87,21

P2 (Digital I/O)

P2 is used with various kinds of digital I/O. For autonomous operation without an attached PC, the P2
outputs may be preset before the acquisition. The P2 digital outputs may be used as alarm outputs to
identify the detection of specified levels in the acquired data.

P3 (Pulse Frequency, High-Speed Digital I/O)

Features and capabilities of P3 signals include:

•

4 16-bit pulse counter channels, scanable along with analog inputs

•

Additional digital I/O control lines for high-speed digital input and output.

•

4 optional, internal, 16-bit ±10 V analog output channels (LBK2), useable for waveform or control

output, or additional control lines for external analog output expansion.

The 16 high-speed digital I/O lines, along with the additional digital I/O control lines can now be used for
real-time digital peripherals such as expanded digital input, or current or voltage DACs.

Optional, internal 4-channel 16-bit waveform/control ±10 V DACs on P3:

•

Initially setup to a static, preprogrammed voltage at the beginning of the acquisition.

•

In the future, may be used for waveform or control outputs.

The following tables give the pinout use for P1, P2, and P3.

System Setup and Expansion Options

Steps to Review

A review of the following steps can help you decide what type of setup best suits your application.
Specifics of your actual application may alter the order and complexity of these steps. These steps should
be reviewed prior to expanding a LogBook system.

1. Determine what data you need and how data will be used and saved. What units, ranges,
sampling rates, etc are best for your needs? Will the data be charted graphically, statistically
processed, or exported to other programs? Are secondary uses envisioned for a later date? Begin by
analyzing the end use of the data and then working backwards to how you must collect it.

Determine the channel assignments, and layout the whole system plan. Typically, a hand-drawn

2.
pencil sketch can effectively note all system components and their relation to the others; however, a
computer-drawn plan can be more useful in a complex system or one that will undergo frequent
modification. Plan out the location of transducers, cable runs, DBKs, LogBook, and the computer.
Assign channel-numbers and apply labels to your transducers, cables, and connectors.
A well-documented and labeled system prevents confusion later on (especially helpful for
troubleshooting and system expansion).

3. Configure all the DBK cards and modules for your application. Some DBKs are configured by
software; however, on other DBKs, jumpers and DIP switches may need to be set manually (channel,
gain, filters, signal mode, etc). Perform all hardware configurations before connecting signal and
power lines.

4. Route and connect all signal and power cables while all power is turned OFF. To minimize
noise, route all signal lines away from any RF, high-voltage, or strong magnetic fields (motors, etc).
The IOtech Signal Conditioning Handbook (ISBN 0-9656789-0-3) contains excellent guidance in
this area.

Additional power may be required for systems that use several DBKs [or transducers].
Chapter 2 contains power supply information and includes a “DBK Power Requirement
Worktable.”

Configure LogBook (most settings are made in software). The software must recognize all the

5.
hardware in the system. Set all channels in the proper mode for the attached signal source; and
configure LogView to use measurement units and ranges that suit your purpose.

6. Energize LogBook and DBKs, and initiate a data acquisition.

7. Verify proper data acquisition and storage. Can data be acquired, stored, retrieved, and used as
needed?

Verify system accuracy; perform calibration or equipment adjustment as required.

8.

DBKs are designed for use with a LogBook or Daq* (DaqBook, DaqBoard, and Daq PC-Card). The DBKs
can also be used with ISA bus-based data acquisition boards from other vendors. However, DBKs perform
best when used with a LogBook or Daq* that can dynamically select both channel and gain/range. Dynamic
channel and gain/range selection allows high channel-to-channel scan rates with a wide variety of
transducers.

No matter what the signal input from the transducer, DBKs produce output signals suitable for analog-to­digital conversion (ADC). The output signals can be bipolar (typically -5 to +5 V) or unipolar (typically
0 to 10 V). The user can select a range of relevant values to correspond to the lowest and highest signal—
this range selection guarantees the highest resolution in 16-bit conversion by the ADC.

Note: DBKs vary in their outputs and gain settings. Refer to the specifications for the particular DBK used.

Most system expansions stem from the 37-pin Signal I/O ports P1, P2, and P3.
LogBook/360 combines the features and capabilities of LogBook/300 with those of a DBK60 expansion
chassis. In addition, LogBook/360 has a pre-installed serial communications card that provides GPS and
AUX serial ports as detailed in chapter 4.

•

P1. Each of 16 main (base) channels can support up to 16 sub-channels and thereby provide
expansion up to 256 analog input channels. LogBook’s channel sequencer scans expansion channels
at the same high speed as the base channels. DBKs can be daisy-chained off the P1 connector of
LogBook or an expansion module. Some DBKs add another level of multiplexing and programmable
gain to each channel, and setting channel parameters properly sometimes requires both hardware and
software setup.

•

P2. The Digital I/O port can accommodate the DBK20/21 (digital I/O cards), DBK23/24 (isolated
digital input/output chassis), DBK25 (8-channel relay card), and other compatible devices; up to
208 digital I/O lines.

P3. The Pulse Frequency port can be used for analog output and other uses. A DBK11A allows easy
connections via screw terminals or optional BNC connectors.

Mechanical Setup Options

g

Convenient modules for packaging DBK expansion cards are available with three slots (DBK10, DBK60)
or 10 slots (DBK41). The best option depends on the number of DBK cards in your system. For three or
fewer cards, you can use the stackable 3-slot DBK10, or 3-slot DBK60.

Note: DBK60 has several termination-panel options, e.g., BNC, Safety-jack, T/C, removable block

screw-terminal, slotted, and DB37-style.

For more than six cards, use the 10-slot DBK41. Several DBK41s can be daisy-chained to handle a large
number of DBKs in a system. Another packaging option is the use of special enclosures for harsh
environments. These enclosures can be locked to prevent tampering, conditioned for heat and/or cold, and
sealed air- or water-tight. For systems with many modules, stacking units together helps conserve space and
assure easy cable runs. Such stacking can be accomplished with adhesive dual-lock tabs or by the use of
fastener-panels (splice plates). The splice-plate method provides for a more rigid stacking, and is the
preferred method. Dual-lock tabs are convenient for mounting a Notebook PC to a LogBook or DBK
module.

System Power Considerations

Power options are available to accommodate a wide range of applications from laboratory to automotive
and other field applications. LogBook power input range is wide (10 to 45 VDC) to allow use in various
environments. LogBook is shipped with the TR-43 AC-to-DC power adapter which plugs into a standard
outlet and the DIN5 power connector on LogBook. Optionally, an 8-ft CA-171 cable can connect to an
automobile cigarette lighter.

Depending on system load, DBK cards can get their power from the P1 bus (either from LogBook or a
DBK power card in a DBK41 expansion chassis). The DBK modules use any 10 to 20 VDC source or the
included AC/DC adapter.

Reference Note: Chapter 2, System Power explains how to calculate and meet the power
requirements for any combination of system devices.

LogBook provides power via P1, P2, and P3. Additional power can be supplied by the following, as
discussed in chapter 2.

Operational Features

Data Acquisition Overview

Note: Acquired data is signal-conditioned before it is logged (recorded by LogBook). The data can be

post-processed via analytical programs.

A Sensor/Transducer reacts to a physical quantity (such as stress, strain, frequency, temperature,
acceleration, light intensity, etc) and encodes that quantity into an analogous electrical signal. A wide
variety of transducers produce signals that vary in type and strength—some generate a voltage; others alter
an electrical property. As the measured condition changes, the analog sensor signal can vary directly or
inversely and in a linear or non-linear way.

Although LogBook can read volts directly, many sensor types still require signal
conditioning before they can be correctly interpreted.

The Signal Conditioner changes the raw transducer signal into a voltage for use by LogBook’s Analog-to-
Digital Converter (ADC). Depending on signal quality, several steps may be involved (e.g., linearization,

isolation of high voltages, amplification of weak signals, attenuation of strong signals, filtering of noise and
irrelevant frequencies, differential voltage measurement, simultaneous sample-and-hold, and pulse/current­to-voltage conversions). DBK option modules are designed for conditioning a particular type of transducer
signal. The signal conditioner’s output voltage range is “normalized” to a user-selected range for the
measured values.

Note: Multi-channel DBKs can multiplex several input signals into one of LogBook’s 16 main inputs.

Multiplexing up to 16 analog channels for each LogBook main channel allows system expansion
up to 256 analog input channels.

LogBook’s onboard microprocessor and PC-Card allow it to operate independent of a host PC.

Functionally, LogBook can perform:

•

Analog-to-Digital Conversion. The ADC changes a conditioned analog signal to a corresponding
digital value. LogBook’s 16-bit ADC uses 65,536 numbers (2

16

) to quantify values within the
specified range and gain. Each input channel’s buffer amplifier ensures constant input impedance.
The buffers also eliminate any noise effects from multiplexing of the input signals.

•

Acquisition Control. The microprocessor controls the data acquisition by managing trigger
conditions, gains, offsets, scan sequencing, and data formatting. LogBook can continuously collect
information, or be used for exception-capturing (with triggers). Pre-trigger and post-triggers allow
for capture of specific data, thus making more efficient use of memory.

•

Analog and Digital I/O. With the standard digital I/O, standard analog input, and the optional
analog output board, LogBook can perform virtually any data acquisition task as well as more
complex tasks for alarm and control systems.

•

Data Logging. Data can be saved in one of several formats and later downloaded to a PC.

•

Communication with PC. LogBook provides for serial and parallel port communication. In the
stand-alone mode, the PC-Card must be manually transported between the PC and LogBook.

The PC-Card is a memory device (rotating or flash, PCMCIA types I, II, or III)) that holds the system
software and the acquired data in multiple formats. System software includes the configuration file that
directs a specific acquisition and LogBook’s operating system. The PC-Card as programmed in LogView
allows LogBook to operate without PC intervention if so desired. LogView can configure a PC-Card in
LogBook if the PC and LogBook are electronically connected via serial or parallel port. In a stand-alone
mode, the PC-Card must be physically transported between a PC with LogView and one or more LogBooks
for uploading and downloading. Using a 500-Mbyte PC-Card, for example, you can store up to 250 million
samples in non-volatile memory; that equates to more than forty minutes of recording time on one channel
at the full 100 kHz acquisition rate. For continuous data collection, PC-Cards can be swapped while the
acquisition is taking place. As one card becomes nearly full, it can be removed and another card inserted
without causing a gap in the acquired data.

The user’s PC (typically a laptop or desktop) runs the supplied LogView software. LogView’s user-
interface includes a virtual instrument panel with meters and controls to fit various applications. Through
LogView you can configure the system, apply further data processing, or manage multiple LogBooks.
LogView stores data in a conventional format so that other software can use the acquired data for analysis,
control, alarms, reporting, etc.

Note: The PC can be attached to LogBook via a serial or parallel connection; alternatively in the stand-

alone mode, the PC can be unattached and communicate with LogBook via a PC-Card that is

Communications

Protocols

LogBook uses only standard, supported, widely available communication channels to minimize device­driver development. The messages transmitted over these channels are also standard: human-readable
ASCII for commands and status, and standard file-transfer protocols (such as X-modem) for block data
transfers. The messages and protocols are independent of the choice of communication channel, except
when a channel explicitly requires a different protocol (such as FTP over TCP/IP). The use of such
standards makes LogBook easier to use and extend.

To implement these standards, LogBook includes a command parser and conversion software to convert
measured voltages into physical measurements such as temperature, force, or acceleration. This software is
used for monitoring transducer measurements, both at the PC and the LBK1. LogBook can return all data
as physical quantities and/or raw voltage measurements.

Large blocks of raw or converted data (such as entire acquisitions or a set of consecutive scans) are
transferred as binary files, using file-transfer protocols. Smaller blocks (such as individual readings or
scans) are transferred in readable ASCII.

LogBook User’s Manual,

System Considerations 1-19

Parallel Port – ECP Mode

LogBook includes an ECP parallel port for high-speed local communication with a PC in the ECP mode
(the only supported protocol is ECP). Your PC mode may need to be changed in its BIOS or in the
Window Settings—consult your PC’s documentation or the PC’s manufacturer as needed.

Serial Port

LogBook includes an RS-232 (RS-422/485 optional, call factory for availability) serial port supporting both
point-to-point and multi-drop remote communication.

Other Communication Channels

The serial communication protocols are standard so non-PC hosts can communicate with LogBook. The
use of printable ASCII for commands and status and the use of standard file-transfer protocols make it
practical to add additional ports such as USB, IEEE 488, TCP/IP. Consult factory for availability of these
communication options.

Triggering and Scan Timing

Reference Note: For information on defining triggering conditions through LogView, refer
to chapter 3’s Acquisition Configuration section.

If data collection is desired only under specific conditions, you can specify appropriate trigger conditions.
By defining a trigger, pre-trigger, and post-trigger, you can collect data surrounding a specific event. This
event can be an absolute time or a defined condition such as a particular analog channel measuring a certain
quantity. If a calculated channel is chosen as the trigger source, you have greater flexibility in defining the
trigger based on multiple inputs and conditional logic. An auto re-arm feature allows many successive
acquisitions to take place automatically, with each acquisition using the same settings.

LogBook can be triggered by several types of sources, including analog and digital triggering, multi-step
triggering, multi-channel triggering, time-of-day triggering, and manual trigger. The manual trigger can be
implemented in the following ways:

•

With a computer attached, you can trigger LogBook from LogView’s LogBook Monitor window.

•

Without a computer, you can use a manual trigger switch by attaching it to the TTL trigger input
(pin 25, on P1).

•

With a logic device you can engage the TTL trigger on P1’s pin 25, as programmed.

•

Without a computer, you can use the LBK1’s manual trigger button.

LogBook time-of-day clock has 1/256-second resolution for data-logging applications where acquisitions
must be performed at specific times during the day. The time of occurrence of each acquisition and its
trigger are also recorded with the data. The scan-to-scan timing may be set by a fixed-frequency pacer
clock. Or, an external clock can start each scan individually to allow the scan rate to track a variable-speed
event (such as engine revolutions).

Note: Time-stamping is done in 1/256-second units; but the absolute trigger is in 1-second units.

For data acquisition applications that include both fast and slow signals, multiple sample rates can be
configured. In the acquisition setup dialog box, a primary acquisition rate and divisors for up to 3 more
rates can be configured. Using multiple sample rates, fast signals like vibration can be sampled at a high
rate while slow signals like thermocouples are sampled at lower rates, optimizing the system’s storage
capacity.

Scan Rate Limitations

LogBook’s internal clock runs at 100 kHz, and this is the fastest scan rate possible with just one input
channel in the scan list and no outputs. As input, calculated, and output channels are added to the scan list,
the usable scan rate is correspondingly reduced. The system does not automatically compute an optimum
scan rate for you. However, LogView will generate an error message in the LogBook Monitor window if
timing problems occur, and the following sections explain such problems and how to solve them.

1-20 System Considerations LogBook User’s Manual,

8-30-99

External TTL Trigger and Stop Events

An external TTL trigger can repeat before the trigger block completes; extra trigger signals will be ignored.
Likewise, multiple stop signals received before restarting the next scan will be ignored. Such ignored
signals are noted in the LogBook Monitor window as “Losing Trigger Events” and “Losing Stop Events”.

Problems Arising From Too Fast a Scan Rate

If the user-specified scan rate does not provide enough time to complete the necessary tasks of the entire
scan list, various problems can occur. Bear in mind that LogBook places the highest priority on reading
input channels—it is primarily a data logger. Also realize that calculated and output channels are based on
input channels and come typically at the end of the scan list. Thus, if the scan rate is too fast and the next
sequence begins before the first is completed, the outputs may suffer. When outputs can’t keep up with the
inputs, possible consequences include:

•

Missing/late Outputs. The outputs are not updated in a timely fashion and may not represent their
sources in real time (LogBook Monitor error message is “Outputs Deteriorating”).

•

Missed Alarms. Digital alarm outputs may not be initiated soon enough—important alarms might
never go off.

•

Faulty Control. Control systems based on digital outputs or a DBK25 could fail if dependent on a
fast critical response time.

•

Distorted Outputs. Analog outputs may appear to be "jaggy" or other distortions such as aliasing­type errors.

Ideally, each output signal is based on one input, resulting
in an accurate output waveform. Factors such as scan rate,
number of output channels and calculated channels can
overload the system, resulting in one output signal for
multiple input scans. The resulting signal deterioration can
increase over time and shows up as a distorted and/or
lagging output signal. Such output errors can resemble
aliasing errors where output signals are distorted from their
input signals because the effective sampling frequency was
not high enough (see figure).

Output Signal Deterioration

Solutions To Scan Rate Problems

To confirm a suspected timing problem with your acquisition, run the acquisition and then check:

•

The LogBook Monitor window in LogView for a corresponding error message.

•

Actual deterioration of outputs as described in the previous section.

To solve timing problems you may need to perform one or more of the following, in order of effectiveness:

•

Choose a slower scan rate, or change the trigger parameters.

•

Reduce the number of output channels.

•

Reduce the number or complexity of calculated channels.

•

Reduce the number of input channels.

Estimating an Optimum Scan Rate

Note: The scan rate can be measured as a frequency in Hz or kHz or as a period in ms or µs. These

two measures are reciprocals of each other; e.g., 1/100 kHz = 10 µs.

Processing input channels is LogBook’s highest priority; each input channel is collected at 10 µs. After all
the inputs are collected, LogBook performs the necessary calculations and then updates the enabled outputs.
The time to perform calculations and outputs varies with the type of calculation, and this makes it difficult
to predict the exact length of time required. Simple calculations are done much faster than functions for
non-linear thermocouples and RTDs or the use of logical and bitwise calculated channels. Output channels
can take from 100 µs to 300 µs; so for very approximate results, we’ll use 200 µs.

To estimate the maximum scan rate, use the following formula:

LogBook User’s Manual,

approximate scan period = (number of inputs × 10 µs) + (number of outputs × 200 µs)

8-30-99

System Considerations 1-21

If only 5 input channels are enabled, the scan period equals 50 µs with a frequency of 20 kHz. If one output
channel is added, the period becomes 250 µs with a frequency of 4 kHz.

After running the acquisition, check the LogBook Monitor screen for error messages.
Appendix B provides a list of Software and Hardware-related error codes.

Use of Outputs to Alarm and Control

Reference Note: For information on how LogView allows you to set outputs based on

user-defined conditions, refer to chapter 3’s section entitled, Calculated-Channel
Configuration.

By careful setup of LogBook’s analog and digital outputs, you can control external devices and/or stimulate
the unit-under-test. Using LogView’s calculated channels, equations can be derived that can be used to
stimulate digital outputs for use as alarms or for on/off control. For example, the equation:

DIG1 = (CH1 - CH2) < 2

turns on digital output “1” if the difference between channels 1 and 2 is less than 2.

The system’s four 16-bit analog outputs can also be used for controlling or stimulating external devices.
Using channel data derived from input channels and equations or canned waveforms, the analog outputs can
be updated at rates as high as 100 kHz.

Acquisition

A selected acquisition can be armed:

•

on command from the keypad or PC

•

at power-on, or

After an acquisition, LogBook may continue the same or begin a new acquisition. The new acquisition can
begin immediately, after a specified time interval, or at a specified time.

Data Storage and Retrieval

The quantity of acquired data can be reduced by block averaging or by decimation (skipping samples
without averaging). Then, data is placed onto the DOS-compatible disk drive using a proprietary format in
a DOS-compatible file. The acquisition setup name and a time stamp are also written to disk.
Post-processing programs can thereby correctly interpret the related data.

The PC can retrieve the acquired data through the serial or parallel port, during or after the acquisition.
Upon command from the PC, LogBook can switch to storing data into a new file. After the PC retrieves
data [from the first file], it can erase that file and reuse the space.

Note: Data is never erased without a specific command from the PC.

Data can also be retrieved from a PC-Card. LogBook copies enough information from the old card to the
new (replacement) card to make sure the current acquisition can continue on the replacement PC-Card.

Replacement PC-Cards for use with LogBook must be pre-configured in order to store
acquisition data.

Improper power use can cause equipment damage. Your system may require additional power
supplies.

Overview

This chapter is import as it concerns system power, and the improper use of power can cause system
damage. The following terms are important in regard to understanding your system’s power needs.

•

Supply of power for the DBKs comes from a LogBook, a power card or module. If needed, the

DBK32A and DBK33 can provide additional power to meet DBK power demands. The LogBook
and DBK power supplies work off low-voltage DC that can come from the supplied AC adapter or 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 (page 2-3) 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:

DBK34

&$87,21

Note: Certain DBK modules have their own power supplies and require only 10 to 20 VDC.

LogBook User’s Manual,

Pin 1: +5 VDC
Pin 2: -15 VDC
Pin 21: +15 VDC
Pin 7 is digital ground; and pins 28 and 29 are analog ground.

8-12-99

System Power 2-1

Use of the DBK Power Cards

The DBK32A or DBK33 power card attaches directly to the P1 analog expansion bus and
supplies power to analog expansion cards. The DBK32A/33 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 the DBK10 three-slot expansion chassis, the DBK32A or DBK33 is
attached via the CA-37-x cable. If used with the DBK41 ten-slot expansion enclosure, it simply
installs into one of the analog expansion slots on the unit’s backplane.

Transducer Power

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.

LogBook Power Requirements

The LogBook uses about 12 Watts. The TR-43 AC-to-DC adapter draws about 15 watts (15 VA) when
powering the LogBook from 115 VAC, 60 Hz. If using battery-power, you can compute operational
endurance from your battery’s watt×hr rating and the following calculation tables.

Calculating Your Power Needs

Use the chart to the right and the worktable
below to ensure your system will have
sufficient power. If the load (calculated in
the worktable) exceeds available power
(from the chart at the right), you must add
a power card or a module such as a
DBK32A or DBK33.

DBK32 7500 mW
DBK32A 15000 mW
DBK33 7500 mW
DBK34 5 A-hr in 12 V mode; fused at 8 A

Use the following procedure and table to calculate the required system power.

1. In the Quantity column (5th), list the number of DBKs of that type in your system.

2. In the Sub Total column (7th), enter the product of column 5 and column 6 (mW).

3. Add the Sub Total column, and enter the sum at the bottom right of the table.
This result is your power requirement in mW.

DBK32, DBK32A, and DBK34 cannot supply +5 VDC.
In cases that require +5 VDC, if the +5 VDC requirement exceeds 500 mW from a
LogBook, then a DBK33 must be used. Note that DBK33 can supply 1000 mW at +5 VDC.

Power Supplies and Connectors

The power supply commonly used with LogBook system is the TR-43. Input is 90-260 VAC, 50 or 60 Hz.
Output is 15 VDC @ 2.3 A via a DIN5 connector on a 6 ft cord.

The DIN5 is the system’s basic power connector (see figure). The CA-115 is a 6-in. cable with a plug
DIN5 connector on both ends. The CA-115 connects DBK32As or DBK33s in parallel to be powered by
the same supply.

Note:

LogBook User’s Manual,

LogBook and DBK34 have inverted DIN5 connectors, relative to the orientation in other DBKs.

System Connections

The LogBook is designed to accommodate various DBK configurations—typically, analog inputs via P1
and digital inputs from P2. The CA-37-x cable comes in several variations with x indicating the number of
devices to be attached. If using an expansion chassis, refer to those sections for related information. The
DBK10 can use a CA-37-3 for 3 DBK cards; a DBK41 can use a CA-37-2 for 10 DBK cards since the
DBK41 has a built-in P1 bus.

Turn off power to all devices connected to the system while connecting cables or
setting configuration jumpers and switches. Electrical shock or damage to
equipment can result even under low-voltage conditions.

Take ESD precautions (proper packaging and handling, grounded wrist strap, etc)
especially in dry or static-prone conditions.

Installation and Configuration

A successful installation involves setting up several pieces of equipment and setting software parameters.
You may need to consult related sections of this manual to get the complete picture.

The DBKs are usually configured before the connections are made and power is applied. This order of
installation can prevent equipment damage and help ensure proper operation on startup.

&$87,21

Many DBKs have on-board jumpers and/or DIP switches used for setting channels and other variables.
These settings are discussed in the individual DBK sections.

For systems with many modules, stacking units together helps conserve space and assure easy cable runs.
Such stacking is facilitated in two ways:

•

Velcro tabs. DBK power cards are shipped with installation kits that include Velcro/adhesive tabs
that allow modules to be stuck together and easily removed as needed.

•

Fastener Panels. A splice kit provides a more rigid stacking arrangement and comes with several
DBK modules. The kit includes metal plates that screw onto the sides of a module and form a
vertical rack of several modules. An optional handle is available for portable use.

DBK30A - Rechargeable Battery Module

DBK30A Front Panel

DBK30A contains two rechargeable nickel-cadmium batteries and shares the same base dimensions as other
LogBook products, allowing for convenient stacking.

The included power adapter converts AC power to 24 VDC for charging DBK30A’s two battery packs.
Automatic charging circuits recharge the internal batteries quickly and safely. The charged battery runtime
depends on the current load and mode of operation.

An internal slide switch (SW2) determines the unit’s mode. The two modes are:

•

14 VDC Mode (default)

•

28 VDC Mode

You should check the power requirements of each component in your system, and then
verify that the power source can provide sufficient power to meet your runtime
requirements.

Fully charge DBK30A’s batteries before use.

14 VDC Mode (

This mode provides 14 VDC for 3.4 A-hr. The typical battery runtime is from 3 to 6 hours depending on the
load. Unless 28 VDC is required, the 14 VDC mode should be used in your LogBook applications.

LogBook User’s Manual,

default

Unless you need 28 V, leave the unit in the 14 VDC mode. Use of the 28 VDC mode results in
a lower runtime, as only one battery pack can be used for 14 VDC. When in the 14 VDC mode,
both packs are used in parallel, resulting in a longer runtime for the same application.

8-12-99

)

System Power, 2-5

28 VDC Mode

The 28 VDC mode actually provides both 14 VDC and 28 VDC. Loop currents for two-wire, 4-20 mA
transmitters (1.7 A-hr) require 28 VDC. The battery run-time typically ranges from 1 to 6 hours, depending
on system configuration. In this mode, 14 VDC is used for unregulated bridge excitation (for bridge­configured sensors, such as load cells), and power to DBK expansion products.

Hardware Setup

Configuration

The only configuration option is the choice of modes (

1. Remove DBK30A’s cover by removing one screw and sliding the cover forward until it separates from

2. Look near the front center of the circuit board and locate slide switch SW2.

3. Check SW2’s selection. The silkscreen indicates the 14 and 28 VDC positions.

The 28 V pin is only active in the 28 VDC mode; however, the 14 V pin is active
regardless of the mode selected.

Cable CA-115 is included in the DBK30A package. The cable connects to
DBK30A’s POWER OUT connector and WaveBook’s POWER IN connector.
The cable can be used to daisy-chain a DBK30A unit to a WBK expansion module.

Charging the Battery Module

To charge the DBK30A batteries:

1. Connect the adapter to DBK30A’s POWER IN connector.

2. Plug the adapter into the AC power receptacle.
Note: The charge cycle will begin automatically whenever AC power is applied after an interruption. The

charge cycle will automatically end when the batteries are fully charged.

3. To manually initiate a charge cycle, press the START CHARGE momentary rocker-arm switch. Note
that subsequent charge cycles applied to a fully-charged DBK30A will have no ill effect. The module
will sense the fully-charged status and revert to the trickle-charge state within a few minutes.

Three LEDs on the DBK30A provide status information on the charging process or the external load.

DBK32A Auxiliary Power Supply Card

DBK32A Power Supply Card

Overview

The DBK32A provides added power in configurations where the number of expansion cards exceeds the
power available from a LogBook. For power, the DBK cards rely on voltages supplied via the P1
connection. The DBK32A supplies ±15 V via the P1 bus and is compatible with all analog DBK cards.

Notes: The DBK32A does not provide +5 V; if +5 V is required by the DBKs in use, you should use the

DBK33 Triple-Output Power Supply Card.

LogBook/DBK Connection

The DBK32A has two DIN5 power connectors to allow daisy-chaining of multiple DBK32As or to share a
common power source with a LogBook or a compatible DBK Module. Terminal block J1B can be used
instead of the DIN5s (e.g., custom wiring with a DBK60). The DBK32A can be powered from the included
AC adapter, a DBK30A battery module, or a 10-20 VDC source (e.g., a car battery).

Connect the DBK32A much like any other expansion card on a ribbon cable or inside an expansion chassis.
The DBK32A can be installed into a DBK10, DBK60, or DBK41.

Note: The DBK32A is shipped from the factory with a protective shield. A DBK32A will not install into a

DBK10 with the shield in place. To remove this shield, remove the five screws from the bottom side
of the DBK32A board and lift off the shield and spacers as one unit. Any slot within the DBK10
may be used.

DBK34 - Vehicle UPS Module

The DBK34 can power a data acquisition system in portable and in-vehicle applications (from 12 VDC or
24 VDC systems). Power storage capacity is:

5 A-hr @ 12 VDC or, 2.5 A-hr @ 24 VDC

For reliable data acquisition in a vehicle, the DBK34 provides clean and consistent operating power for the
following instances:

•

Prior to engine/generator start.

•

During engine start-up (battery sag due to the high-current demand of starter motor and solenoid).

•

After engine turn off.

DBK34 contains two sealed-lead rechargeable batteries, associated charging circuits, and current indicators.
Typically, the batteries can last more than 500 full cycles and up to 10 years standby lifetime at room
temperature. Recharging is fast, and extreme temperature performance is good. DBK34 can be used with
LogBook, DaqBook, WaveBook, and related DBKs and WBKs. The unit’s rugged metal package has a
compatible 8×11” footprint for convenient stacking with Velcro tabs and optional splice plates and handles
for carrying.

Main and auxiliary power input comes from 12 or 24 VDC via a terminal block (TB1) on the unit’s front
panel. The voltage mode is configured with jumpers on TB1. Automatic charging circuits recharge the
internal batteries quickly and safely. The charged battery runtime will depend on the load and mode of
operation.

DBK34 Front Panel

Note: Current protection is provided by four fuses. Two 8A fuses for the units internal batteries, one 8 A

fuse for an auxiliary (external) battery, and a 15 A fuse for a vehicle battery.

You can use a CA-172 cable to connect a vehicle battery (via a cigarette lighter) to the DBK34
terminal board. The cable is six feet long, contains a cigarette lighter adapter at one end, and
stripped leads (for terminal connection) at the other.

For trouble-free operation, you must fully charge the batteries before use.

Understanding LogView

LogView provides for easy setup and operation of LogBook. LogView’s flexibility can handle virtually any
data-acquisition environment. The graphical Windows interface can display a variety of spreadsheets,
dialog boxes, graphs, charts, and meters; and accepts user input from a mouse and keyboard. The easy-to­learn interface does not require programming or the configuration block diagrams.

It is important to understand the central role of the PC-Card in LogBook/LogView operation. When
LogBook operates in a stand-alone mode (not attached to the PC), LogView must download the system and
acquisition setup files to a PC-Card. The PC-Card must then be manually transferred to LogBook. Later
LogBook’s PC-Card must be transferred back to the PC for uploading. When LogBook and PC are
attached in direct communication, LogView can download to [or upload from] LogBook in real time via the
communications link.

Modes of

LogView

Operation

The next figure outlines LogView’s functional modes to help you visualize what LogView can do. This
functional organization is not the same as the menu organization.

Setup

System Setup includes the hardware, the channels in the scan, and the triggering. Before data acquisition
can begin, all setups must be complete and the resulting setup file downloaded to the PC-Card in LogBook.
[page number references shown in parentheses]

•

Hardware Configuration asks you to set the software parameters to match your hardware. For some
DBKs, you may need to adjust the DBK’s jumpers and DIP switches—or at least verify that the
LogView software setting matches the DBK hardware setting (3-26).

•

Channel Setup includes setting parameters as needed for the 4 different types of channels. These
parameters vary by the channel type but are all set in software. The 4 channel types are: Analog Input
(3-27), Digital Input (3-29), Output Channels (3-31), and Calculated Channel (3-31). The flexibility
of the Calculated Channel allows you to create a virtual channel based on math and logic functions of
real channels (analog and digital), other virtual channels, and arbitrary numerical values.

•

Acquisition Configuration asks you to determine when, how often, and for how long to get data
readings. Trigger/pre-trigger/post-trigger conditions and timebases are discussed on page 3-37.

•

System Calibration allows you to perform 1- or 2-pt calibrations to fine-tune system accuracy.

3-2

LogView

Monitor

•

Monitor Acquisition. In real-time, LogView can display system parameters and channel values in a
spreadsheet style. If so desired, readings can be formatted into bargraphs, analog meters, and digital
indicators (3-48).

•

LogBook Monitor shows you the status of the current acquisition and the LogBook system (3-43).

•

Programmed Digital Outputs Used As Alarms. The monitoring function can be automated via
calculated channels and digital outputs to engage alarms when pre-defined conditions occur.

•

Display Recorded Data. DIAdem (called independently, or from within LogView) allows you to
graphically view previously recorded data for analysis and comparison. DIAdem is covered under
separate documentation. Another program, PostView, can also be used to view and analyze data.
PostView is discussed in Appendix F.

System Management

LogView allows you to manage aspects of an acquisition in progress and file saving/conversion:

•

Direct Acquisition Controls of LogBook include manual triggering and setting reference marks (via
LogBook Monitor, 3-43) and starting/stopping an acquisition. In these ways, LogView gives you
immediate access to LogBook operation.

•

File Management includes managing data/configuration files and converting data file formats. The

LogView Explorer window allows you to manage files on the PC-Card.

LogBook User’s Manual

Communication

Communication between LogView and LogBook is actually between the PC and a PC-Card. During the
communication, the PC-Card can reside in a LogBook for direct (attached) communication or in the PC’s
PC-Card socket for indirect (unattached) communication (and later manually transferred to LogBook).

Whether direct or indirect, communication involves downloading and uploading:

•

Downloading sends the acquisition setup file (created in LogView’s Setup mode) to LogBook’s
PC-Card. LogBook uses the setup file to run the acquisition (also needs

•

Uploading receives recorded data from LogBook’s PC-Card. After the data has been collected and

).

temporarily saved on LogBook’s PC-Card, the data must be uploaded to LogView for processing,
conversions, use in other programs, and/or archival saving.

In the Direct (Attached) Communication mode, communication occurs through the electronic connection
(cabling via serial or parallel port). While attached, LogBook can do 2-point calibration, look at current
readings, and download/upload without handling the PC-Card.

Note: In some cases, data transfer may be faster by placing LogBook’s PC-Card in the computer’s

PC-Card socket and bypassing the attached communication.

In the Indirect (Unattached) Communication mode, no electrical connection exists between the PC and
LogBook. A PC-Card carrying the setup file and/or data must be physically transported between the PC
and LogBook.

Note: The LBK1 remote operation terminal can be used with an unattached LogBook for limited control

LogView

Features and Capabilities

In setting up an acquisition, LogView can:

•

Configure parameters for all input, output, and calculated channels without using special programming
skills.

•

Provide flexible triggering to acquire continuous data, capture exceptions or, to trigger based on
calculated channels.

•

Configure and operate expansion chassis, including the DBK option cards and modules designed for
various signal-conditioning environments.

•

Provide utilities (convert units, calibrate sensors, calculate channels, control outputs/alarms, etc).

In handling data, LogView can:

•

Download an acquisition setup file to a PC-Card for physical transport to a remote LogBook, or send
the setup file directly to the PC-Card in a LogBook via the serial or parallel port.

•

Upload the recorded data from LogBook by corresponding means.

•

Create files for use by other Windows programs; e.g., database or analysis.

Utility-wise, LogView can:

•

Calibrate all gains and offsets on a per-channel basis.

•

Launch DIAdem, a separate program that allows you to graphically view pre-recorded data. DIAdem
is described in separate documentation.

•

Interact with LogBook while the acquisition is taking place including manual trigger and event
marking.

In monitoring an acquisition, LogView can:

•

Display readings and status in real-time. On-screen indicators provide channel feedback during an
acquisition. Channel values can be displayed in charts, bargraphs, analog meters, or digital readouts.

•

Show system status including trigger status, errors, alarms, etc.

Software User-Interface

LogView’s user-interface uses a control window with toolbar/menus and a spreadsheet model. Similar to
other Windows-based programs, LogView’s user interface will seem familiar and intuitive. Windows can be
sized and placed to best fit your application. Several different meter styles are available to monitor data in
real time if so desired.

Control Window (Pull-Down Menus and Toolbars)

LogView pull-down menus (above) are discussed in the section, Menu Descriptions. The following figure
shows LogView’s control window. Note that two sets of toolbar buttons reside just below the row of
pull-down menus.

Analog Input Channel Configuration Window, Spreadsheet Portion

LogView’s spreadsheet-style setup provides a simple method of both viewing and configuring the
parameters of the input, output, and calculated channels. Several spreadsheets are needed to display all the
channels’ parameters. LogView’s spreadsheet windows include:

•

Analog Input Channel Configuration (see page 3-27 for details) - This default-opening window has
more parameter columns than will fit in view at one time. Therefore, the left-most (white) columns are
shown in every view; these parameters include: Physical Channel, User Label, On/Off, Reading,
Range, Units, and Channel Type. The right-most (shaded) columns vary depending on which folder
tab is selected. Each tab (Storage, DBK Parameters, User Scaling, and 2-Point Calibration) has tab­specific parameters.

•

Digital and Counter Input Channel Configuration (see page 3-29) - LogBook has three 8-bit
digital ports and one high-speed 16-bit port configurable as inputs or outputs. Digital expansion cards
can provide up to 192 digital bits. There are also 4 pulse-input ports that can count pulses for
summing and/or frequency measurement.

•

Output-Channels Configuration (see page 3-31) - This window shows all the currently-available
digital and analog output channels. Each output channel is fed by a user-set source channel. Source
channels can be chosen from any of the input (hardware) channels or calculated (virtual) channels.

•

Calculated-Channel Configuration (see page 3-31) - LogView can derive virtual channels using
standard math operators and functions (<, >, min, max, etc). Virtual channels can be used to create
alarms, reduce data statistically, develop sophisticated trigger equations, and manipulate input channel
values for more useful output including simple control systems.

Help Box

The bottom of the spreadsheet contains a context sensitive Help Box for the selected field. As you
configure channel parameters, the Help box identifies the field and provides pertinent user information. An
example, taken from the previous figure, follows.

3-6

LogView

Example: In the above figure the User Label cell (of channel 1) is selected. The Help box identifies the

field as “User-specified channel label” and states user options. In this case, they are (1) to type
in a desired label, i.e., to provide the channel with more meaningful name [not to exceed 16
characters]; or (2) keep the default label of P1_CH00.

User Input

To set up channel parameters, first select the appropriate cell (highlighted in a bold box) with the mouse or
keyboard arrow keys (up/down/sideways). Some cells allow you to key-in values from a keyboard (values
such as user labels, offsets, etc). When key-in cells are selected, a user-input box will appear where you can
type in characters as needed (e.g., channel label in previous figure). Some cells allow you to choose the
desired setting from a drop-down list; you select among the options, and the parameter is set. Other cells
allow you to set numeric values with “spinner” up/down arrows that change the value incrementally
(selecting a point between the spinners changes the mouse action into a virtual scroll bar—as you drag the
mouse vertically, the numeric values change accordingly).

9-1-99

,

LogBook User’s Manual

User-set parameters can be set individually per channel, or the same value can be “filled down” for an entire
column. To apply the same column setting to multiple channels, use the spreadsheet’s fill-down feature.
Select multiple cells in a column by dragging the mouse with the left mouse button (or using the <Shift>
and arrow keys). Enable the fill-down feature with the right mouse button.

As a shortcut to toggle channel readings on or off, you can place the cursor in the Reading column and
double-click the mouse. Another alternative is to double-click the column title, and every channel value in
the column will change to the next value if such a value is list-selectable. Globally, you can switch all
channel readings in the Indicators menu as Start All Indicators and Stop All Indicators.

file.

Data. Names for the data files use a long format convention as described
below. The Preferences window from the View pull-down menu allows you to
customize how your data files will be named.

File Organization

As data is uploaded to the PC, LogView first uploads the raw data file(s) and then
converts them into the formats specified in the Preferences window. The raw binary
files are placed in the DATA directory in the path specified during a configuration
save. If the configuration was never saved, the DATA directory will be created in
the LogView working directory. LogView creates a sub-directory within DATA for
each file format selected. The figure shows a typical file structure.

Data Filename Generation

Uploading can create one data file or many data files. A simple, completed data collection with one
timebase will produce only one data file. More complex conditions will create multiple data files. When
these conditions exist, LogView creates a file-set rather than a single file.

These configurations will create multiple data files during an upload.

LogBook User’s Manual,

With multiple timebases enabled, LogView generates a separate file for each rate.
With Auto Re-arm set greater than 0, multiple trigger blocks will be collected—each in a separate file.

When LogBook configuration is re-armed through LogView or by cycling LogBook’s power, a new
file-set is created.
When a partial upload takes place with an attached LogBook, a new file-set is created.
When a partial upload takes place from a PC-Card in the PC’s socket, a new file-set is created.

A partial upload saves part of the data from an active acquisition. Three ways to perform a partial upload:

a) During an acquisition, connect your PC to LogBook and execute an upload. To make room for

additional data, the uploaded data is deleted from the PC-Card.

b) During an acquisition, swap the PC-Card in LogBook with a different card. Then insert the card into

your PC, and perform an upload.

c) Start an upload of any kind; then click Cancel while the upload is taking place.

Naming Format for Data Files

LogView names uploaded data files to make them easy to identify and organize. The File Converter
Preferences window (Represented below) allows you to customize LogView’s naming process to suit your
needs. Navigate as follows to access the window: View Pull-down menu ⇒ Preferences ⇒ File Converter.
Preferences can be set so:

•

Files will not be accidentally overwritten

•

The use of several LogBooks is easy to manage.

•

Test times and dates automatically embedded

•

It is easy to identify files that are part of the same acquisition

The figure and table below define the full-field format for data files. As described in the next section, you

Under certain conditions, all filename fields may not be needed. To turn off fields, simply enable or
disable the check boxes in the Upload tab of the Preferences window (see figure here and discussion on
page 3-40). Be aware that simplifying the filename removes the safeguards to prevent 2 files having the
same name and causing an overwrite/lost information condition. If fields are disabled, overwrites are
more likely to occur.

The following table suggests when it is safe to turn off various filename fields.

Condition Recommendation

I want to overwrite old data every time I perform an upload. No optional fields are required.
I only have one LogBook. Turn off LogBook serial number field.
I use a new seed every time I upload. Only the seed option is needed.
I often accumulate multiple acquisitions on the PC-Card and
want to upload them at one time.
I never perform partial uploads. Don’t need block number.

Make sure at least the time field is enabled; otherwise,
acquisitions will be overwritten as they are uploaded.

Example of all parameters: LAB1 #123456 D03-15-98 T12-04-12 R1 B1-1

Simplest application. If a new acquisition is uploaded, this file will be overwritten:

Rate = 1

Trigger block = 1, Segment = 1

If all acquisitions are performed in the same day, the time can identify the files:

The example below shows data files from an acquisition with 2 trigger blocks and 2 timebases; the
acquisition was uploaded in segments. All the dates and times are the same because these trigger blocks are
all part of the same acquisition. The first two files represent a continuous data collection—2 files exist
because of partial uploads.

How To… Procedures

Because of LogView’s flexibility, this manual can not detail every possible use of the system. Instead, these
procedures explain how to perform typical tasks. Understanding these tasks will help you apply the
principles to a variety of data acquisition environments. For your particular application, you may need to

Using an Attached LogBook

When using an attached LogBook, LogView communicates directly to the PC-Card in LogBook through the
communication interface (serial or parallel).

After LogView recognizes the attached LogBook, an acquisition setup file can be downloaded to LogBook.
After the acquisition, data can be uploaded from LogBook without handling the PC-Card. Note that steps 1
through 4 are often done during the initial installation.

LogBook User’s Manual,

Basic Operational Flow of a LogBook Acquisition

LogView

3-11

1. On your PC with LogView already loaded, open control panel applet, and check Hardware
Configuration. If no LogBook is present in the tree, click Add Device and a LogBook ID; otherwise,
select a LogBook in the tree and click Properties.

2. Under LogBook Properties tab, enter or
verify device name, the connection type,
the protocol, a timeout duration; and
then click Apply.

3. (if serial connection) Under Port Settings
tab, select baud rate and related
parameters; and then click Apply.

4. Verify proper LogBook connection and
power-on; then, under the Test Hardware
tab after, click the Test button. Testing
will verify system parameters and then
bench-mark system communication
performance.

5. Launch LogView from your PC (unless you set up a shortcut, you can find LogView in the Programs
group in the Start menu). The control window and the Analog Input Channel Configuration window
should appear.

6. Under the Device menu in the control window, click Select LogBook. From the drop down list,
select LogBook you just configured in the hardware tree; then click the Attach icon to establish a
communications link. The Upload and DownLoad buttons in the Control Window should now be
enabled (LogView recognizes when LogBook is attached and enables the applicable tools as seen by
their lettering turning from gray to black).

7. In LogView’s Analog Input Channel Configuration (see page 3-27) and Acquisition Configuration
(see page 3-37) windows, set up the channels and trigger parameters you wish to use (see Simple
Data Logging, page 3-13).

8. Download the acquisition setup file just configured to LogBook

9. Click the Arm Acquisition button ("). LogBook is now armed and ready to collect data when the
trigger parameter is satisfied.

10. During the acquisition, you can monitor system status via LogBook Monitor window accessed from
the Device pull-down menu. To verify proper operation, such monitoring is recommended for the
first run of a new acquisition setup file.

11. After collecting data, click Upload to pull the data into the PC (see page 3-23). Depending on the
communication channel and size of data files, uploads take a variable amount of time. Uploads can
also be done incrementally during an acquisition.

The next time you launch LogView, it will automatically look for the selected LogBook and attempt to
attach itself. At this point, LogView and LogBook will be in constant communication. If you want to turn
off LogBook’s power or detach the communication cable, you should first select Break from the Device
menu or Exit from the File menu.

PC-Cards purchased with LogBook have been initialized at the factory. PC-Cards
purchased elsewhere must be initialized through LogView. The initialization procedure
is discussed in the following paragraph.

Initializing a PC-Card
PC-Cards, that were purchased with LogBook, have been initialized. PC-Cards purchased elsewhere
must be initialized. Initialization is accomplished as follows:

LogBook User’s Manual

Using LogBook “Unattached”

When using a LogBook “unattached,” LogView
does not communicate in real time with
LogBook; instead, LogView downloads the
acquisition setup file to a local PC-Card that can
later be manually transferred to LogBook.

After the acquisition is complete, the PC-Card
that collected data in LogBook must be
manually transferred to the PC where LogView can then upload the data. The PC-Card must first be
properly initialized :

1. Take any ATA PC-Card memory device, and insert it into a corresponding socket on the PC. If this
is the 1st time this type of card has been inserted, Windows may require driver information. Follow
the on-screen instructions, or refer to the documentation included with the PC-Card.

2. Launch LogView from your PC (unless you set up a shortcut, you can find LogView in the Programs
group in the Start menu). The control window and the Analog Input Channel Configuration window
should appear.

3. Under the Device menu, click Select PC-Card. Use the drop down list to tell LogView which drive
letter is associated with the PC-Card. Note: as PC-Cards are inserted
and removed from the sockets, Windows will arbitrarily assign drive
letters. If 2 PC-Cards occupy 2 sockets, the order of their insertion
usually dictates the assignment of drive letters. The Attach, Upload,
and Download buttons on the Control Window should now be enabled.

4. In LogView’s Analog Input Channel Configuration and Acquisition Configuration windows, set up
the channels and trigger parameters you wish to use (see Simple Data Logging below).

5. Download the acquisition setup file (

6. Eject (remove) the PC-Card from the PC socket, and transport it to the remote LogBook site. Insert
the PC-Card into LogBook's socket, and power up LogBook. LogBook will automatically load the
setup file and arm the system.

7. After the remote LogBook has collected all the data, remove the PC-Card from LogBook's socket,
transport it to the PC, and insert it into the PC's socket. If LogView is running, it will soon recognize
the presence of the card and enable the Upload and Download buttons.

8. Click Upload to pull the data into the PC.

logbook.sys

will also be downloaded if not already present).

After telling LogView which drive letters are associated with PC-Card disks, LogView will periodically poll
the system for their presence. As cards are inserted and ejected, LogView will automatically enable and
disable the Upload and Download buttons.

Simple Data Logging

To log data, you need to configure the hardware, set up the channels, and configure the acquisition
parameters. The following steps are generic and will vary with different applications.

1. Launch LogView, and Attach LogView to your Logbook if working in an attached mode or to a
PC-Card inserted in your PC if working in a remote, unattached mode (see previous 2 procedures if
necessary).

2. Select New under the File menu or the “New” button, and give the acquisition setup file a
name relevant to your application.

3. Click the Analog Input button to display the setup grid in the Analog Input Channel
Configuration window. Turn all but the 1st 4 channels off (or as applicable) by placing the
cursor in the On/Off column and double-clicking to toggle the setting on and off (unused
channels that are left ON will limit the maximum scan rate possible). To change the Range
for a particular channel, click the cursor on the affected and then use the drop down user
input box to select an appropriate range (can be bipolar or unipolar).

LogBook User’s Manual,

9-1-99

If a large quantity of data will be recorded, you should return to the remote LogBook
in time to swap PC-Cards [before the first card is full]. Card swapping is discussed on
page 1-7. All PC-Cards to be swapped must first be initialized as discussed in the
previous section.

7. After verifying that all settings are as you desire, select Save under the File menu and associate a
name to your acquisition setup file (if not already done so).

8. From the main toolbar, click the Download button to send the setup file to
LogBook’s PC-Card.

9. To arm an attached LogBook, click the Arm button.

10. To arm a remote LogBook, eject the PC-Card, transport it to LogBook, insert
it into LogBook's socket, and then apply power.

11. To upload data from an attached LogBook during an acquisition or after the acquisition is
complete, click the Upload button.

12. To upload data from a remote LogBook after the acquisition is complete or as part of card
swapping, eject the PC-Card from LogBook and transport to the PC’s socket; then click
the Upload button.

13. To inspect the data, click the DIAdem button. Note that DIAdem is covered in separate
documentation.

Setting Up DBK Cards

DBK cards and modules provide channel expansion and signal conditioning. For
proper operation, you must use LogView for software configuration of the DBK cards.
All hardware configuration-related parameters can be found in the LogBook Hardware
Configuration Window (sometimes referred to as a “hardware tree”).

1. Open the LogBook Hardware Configuration Window by clicking the Hardware Configuration button.

2. To add analog input DBKs, select P1 Analog I/O in the tree, and set its property to Single-ended.
Digital DBKs use P2 port and are set up in a similar way.

3. Select a channel and assign it either a local channel or a specific DBK expansion module that will
multiplex several channels into the same main channel. See following figure.

Reference Note: Chapter 5, DBK Expansion Options, contains parameter definitions and
information as to which parameters are set in hardware and which are set in software.

Setting Analog I/O Channel P1_CH00, DBK52 T/C Card Selected

4. Most DBKs have related cards and sub-channels as part of their method to multiplex up to
16 channels into each main channel. Click the appropriate checkboxes to set up the channels; and
then OK to accept these settings. See following figure.

Selecting Applicable DBK4 Dynamic Signal Cards

5. Click the Analog Input button to view the newly setup channels in the Analog Input
Channel Configuration spreadsheet (see page 3-27). Verify all channel numbers and
assign user labels as desired.

Note: In some cases, such as with DBK19, channel values are returned in units of temperature,

instead of volts.

6. From the Analog Input Channel Configuration window, select the DBK Parameters tab to view
specific settings for each DBK channel. Set the DBK parameters at this time. If necessary, refer to
the DBK chapter for an explanation of the parameters; for example, DBK4 programmable filter
values and DBK7 debouncing times.

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.

LogBook User’s Manual,

9-1-99

Setting DBK Parameters in the Analog Input Channel Configuration Window

LogView

3-15

When configuring DBKs, the LogBook Hardware Configuration Window provides a means of setting up all
manual hardware settings. Once configured, the analog and digital channel setup spreadsheets provide a
means of setting up channel-specific, programmable features.

Some DBKs have hardware settings that must be manually set inside the DBK, such as
jumpers or DIP switches. For DBK hardware configuration, refer to the applicable
DBK in chapter 5. In these cases the parameter setting in LogView must match the
actual hardware. Setting one does not automatically set the other; in other words, you
must make configuration settings in both software and hardware, when applicable.

Using Multiple Timebases

LogBook is capable of storing channels at 4 independent timebases (one base rate and 3 rates that are
divisions of the base rate). Two reasons for using multiple timebases are: first, to reduce the amount of
storage required by saving slow channels at a slow rate—acquisition can last longer before filling up the
PC-Card; and second, to provide noise reduction by averaging and thus enhance the value of the data.

1. Open the Acquisition Configuration window (see page 3-37) by clicking the
Acquisition Configuration button.

2. In the scan rate frame at the right of the window, set the Base Rate A to the maximum
frequency required for any channel.

3-16

LogView

Acquisition Configuration Window

3. Check all three rate checkboxes B, C, D. Type in a divider for rates B through D to create sub-rate
sampling frequencies which are based on Base Rate A. LogView will compute and display the
corresponding rates in frequency or period units.

Note: The higher the divider (right most column) the slower the scan rate.

4. To reduce noise in sensitive channels like thermocouples, these channels can be sampled at a high
rate but stored at a slower rate after mathematically averaging the intermediate values. By checking
the Apply Noise Reduction Averaging checkbox, channels stored at a sub-rate will store the average
of all of the values collected at the Base Rate A. Extraneous values that are obvious errors will have
less effect on the data—it’s also possible to set up a calculated channel that only accepts values
within a defined range.

5. Close the Acquisition Configuration Window.

6. Click the Analog Input button to display the Analog Input Channel Configuration window. Under the
Storage tab, note that the newly configured sample rates are enabled. The sample rate columns
determine the rate at which each channel’s data will be stored. Each enabled (On) channel can have
data stored at sample rates A, B, C, D (or a combination, there of), see following figure.

9-1-99

,

LogBook User’s Manual

Setting Sample Rates for Data Storage. Each enabled channel can be assigned up to four rates.

7. Set the cells in these four columns to Yes or No, as desired, for all enabled (On) channels.
Channels shown as “Off” are not sampled.

8. Once configured, download the acquisition setup file, and initiate data collection.

Using Digital 2-Point Calibration

Remote LogBooks can not be calibrated. 2-point calibration can only be performed
when LogBook is attached to the PC via a communication interface.

2-point calibration allows you to mathematically “trim out” inaccuracies in the measurement equipment
and/or the transducer. By allowing the equipment to measure 2 known points in the measurement range,
LogBook can calculate linear constants (the scale and offset) to correct inaccuracies in its analog inputs
(see page 3-28). For channels where only one known point can be applied and verified, LogView
provides offset trimming.

1. Click the Attach button to establish communication with LogBook.

2. Click the Analog Input button to open the analog input spreadsheet.

3. Click the 2-Point Calibration tab to expose the calibration columns. If some columns are obscured,
scroll to the right to reveal them or resize the window by dragging the right edge further to
the right. Note that the default Cal Scale and Cal Offset [mathematically applied to each
channel] are 1 and 0, respectively (right-most columns).

4. Apply a voltage to channel 1 near the bottom end of the measurement range.

5. Type the known value into the Set P1 column for the associated channel.

6. Click the Execute button under the Get P1 heading. This allows you to read the channel and

calculate the required offset. Note that the channel value read is now shown in the Actual P1 column
and the Cal Offset column now shows the correction factor.

7. Apply a voltage to channel 1 near the top of the measurement range.

8. Type the known value into the Set P2 column for the associated channel.

9. Click the Execute button under the Get P2 heading to read the channel and calculate the required

offset and scale. Note that the channel value is now shown in the Actual P2 column. The Cal Offset
and Cal Scale columns now show the correction factors.

For channels using thermocouples, it may be impractical to provide more than one
calibration point. In such cases, apply just one known point in Set P1, and click the
corresponding Execute button. This will adjust the offset only, which is typically the source
of most transducer error.

For strain gages, use the User Scaling tab to enter the transducers' transfer functions (e.g.,
volts to pounds), then use 2-point calibration to periodically trim the scale and offset. This
eliminates the need to manually adjust sensors using hardware potentiometers.

Using Digital Outputs As Alarms

Using LogView's calculated channel capability (see page 3-31), digital outputs can be stimulated by events
such as signal levels in analog inputs (e.g., to sound an alarm at a rising temperature before a test system
over heats).

1. Click the Analog Input button to activate the Analog Input Channel Configuration
window.

2. Turn on the analog input channel that you'd like to use to stimulate a digital output
channel.

3. Click the Calculated Channel button to open the Calculated Channel Configuration
window.

4. Click the Add New Channel button (located just right of the F(x) button); or select “Add
New Channel” from the Edit pull-down menu to activate the first or next calculated channel.

5. In the Calculated Function column, type in the following equation "(P1_CH00 > 30.0) & 1". If you're
not using channel 0, replace P1_CH00 with your channel tag. This equation will yield a 1 in its least
significant bit when the value of channel 0 is above 30, and 0 when it is below 30.

Entering an Equation (Function Expression)

To verify accurate use of syntax, use the Equation Assistant F(x) and the Validate button
(see following figure). The Equation Assistant is accessed via the F(x) button. Refer to
page 3-33 for detailed information regarding the Equation Assistant.

The Equation Assistant can be used to create and validate equations.

6. In the Calculated Channel setup grid, set the newly configured channel to “On.”

7. Close the Calculated Channel grid.

8. Click the Output I/O Setup button. If no digital output rows are present, click the

LogBook User’s Manual,

Hardware Configuration button in the main toolbar and add a few digital I/O ports as
outputs; e.g., the LBK2 DAC on the P3 port.

9. Select an output port; then set its Source to the calculated channel that we just configured. Unless
you changed the label in the Calculated Channel grid, the source will be CALC_00.

10. Once configured, download the configuration to initiate data collection with the specified alarm
output.

Using Exception Capturing

LogView can be set up to wait for defined events to occur, then capture data until another specified event.
The triggering process is controlled through the Acquisition Configuration window (see page 3-37). If Auto
Re-arm is used, LogBook will then re-arm itself after each triggering sequence, waiting for the occurrence
of the next trigger event. This setup allows LogBook to capture specific events rather than a continuous
data stream that may be useless in some applications. Exception capturing is useful where continuous data
would soon fill up the PC-Card with low-value data.

1. Click the Acquisition Configuration button to open the Acquisition Configuration window.

2. Set up the trigger parameter as required. The trigger can be set to various parameters
including the level of an analog input channel where you can select a threshold and
hysteresis with rising or falling edge. Trigger sources include analog input level, digital channel,
immediate, absolute time, and manual Event Mark.

In the manual mode, you must select the Enable Event Mart checkbox so that the
Event Mark buttons on LogBook Monitor window and on the LBK1 are activated.

Setting Up the Trigger Parameter

3. In the Pre-trigger tab, set up a duration of time occurring before the trigger event that you would like
to save data for. Exception capturing is most effective when you can set trigger parameters to isolate
the particular data of interest (e.g., all data 2 minutes before and after a specific event).

4. In the Post-trigger tab, you can set the stop event based on a duration, an analog or digital event, or a
manual Event Mark.

Upload

or

The Upload command uses LogView’s Explorer to get data files from a PC-Card. The PC-Card can
reside in LogBook if LogBook is attached to the PC or in the PC’s card slot if the PC-Card was
manually transferred from a remote LogBook.

Note: The Upload icon and the Explorer item in the Device menu can upload from both LogBook or

the PC’s card slot; in either case, the icon looks slightly different as shown at left.

When the Upload button is clicked:

•

If only 1 acquisition file (inactive) resides on the PC-Card, all that data is uploaded to the PC’s
hard drive.

•

If more than 1 acquisition file resides on the PC-Card, an exploring window will appear and allow
you to select which acquisition files or trigger blocks you may wish to upload.

•

(attached mode only) If the only acquisition file on the PC-Card is active, all acquired data will be
uploaded. To prevent duplication of records and conserve storage space, data already uploaded is
then deleted from the PC-Card.

The buttons at the bottom of the window (see figure) allow you to:

•

Upload All the files on the PC-Card to your PC’s hard drive with the designated Path and delete data
on the PC-Card if “Delete on Upload All” is selected in LogView Preferences. Note: with attached
mode and an active acquisition, this is the only way to upload data.

•

Upload Selected uploads only those files which you select.

•

Delete All the files on the PC-Card.

Analog Input Channel Configuration

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, real-time Reading, Range, Units, and
Channel Type columns. Clicking a tab exposes one of the four sub-windows of parameters including
Storage, DBK Parameters, User Scaling, or 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 enter a more
descriptive user label.

In the User Label column, use the default channel labels or insert your own labels of up to 16 characters
(the column width is flexible). Labels are saved with the data so more meaningful channel names will
appear in your post acquisition display-and-analysis software. For example, a calculated channel that
controls an alarm can be so named; several channels that are combined for a calculated channel can be so
named, etc.

In the On/Off column, use On to enable or Off to disable channels. System performance for the enabled
channels is improved by disabling (not sampling) the channels not in use.

The Reading column displays the real-time channel value in the user’s units. The immediate feedback by
this column allows you to optimize range settings, verify scaling, or validate sensor calibration.

For the Range column, all LogBook channels and most DBK cards have a programmable gain amplifier
(PGA) that provides multiple ranges. Adjusting the range allows you to zoom in or out on 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.

LogBook User’s Manual,

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, a User Label of
P101Alarm would be logical.

The next figure shows the columns accessible with the Storage tab selected (default). If channels are
sampled only to derive calculated channels or stimulate outputs, they do not need to be stored. For
example, a channel can be sampled at a high rate to prevent aliasing while a calculated channel is used to
derive and save its maximum every 10 seconds. In this case, only one sample every 10 seconds is saved,
rather than thousands. The Sample Rates columns in read-only mode are set up in the Acquisition
Configuration dialog box where up to 4 timebases can be defined. For applications with slow and fast
signals, slow signals can be sampled at a slower rate, optimizing the system’s storage capacity. The base
rate A can be divided by 3 divisors for rates B, C, and D (see page 3-39)

The User Scaling tab shown above has Scale and Offset columns. In User Scaling, you create a transfer

your Units (apples, oranges, whatever) based on the raw input value, typically Volts. To do so, type your
new unit name in the Units column and select an appropriate range (e.g. unipolar). Then, enter its linear
scale relation to the Volt (e.g. 25 pounds per Volt) and any offset from 0 (e.g. the empty basket measures

0.1 V). The reading and range columns change accordingly.

Analog Input Channel Configuration, 2-Point Cal Tab Selected

Calibration. The above figure shows the columns in the 2-Point Calibration tab. To fine tune the
accuracy of the value coming from a linear sensor, LogView provides both 1- and 2-point calibration. One-
point calibration can be used to zero a channel—as in a thermocouple, which is usually more accurate in
scale than offset. You might place the thermocouple in an ice bath and set just the 0°C point. 2-point
calibration determines the scale and offset factors to convert the raw readings into accurate calibrated
readings. 2 points of known (set) values must be compared with 2 sensor (actual) readings.

For example, to calibrate a strain-gage scale, unload the scale, type 0.0 into the Set P1 column, then click
the Get P1 Execute button to read the actual sensor value (2.0). Place a known 100 lb weight on the scale;
type 100 into the Set P2 column; then click the Get P2 Execute button to read the actual sensor value (95.0).
LogView automatically computes the Cal Offset factor (near 0) and Cal Scale factor (near 1). From now
on, LogView automatically applies the y = mx + b calculation to the incoming reading to produce the
calibrated reading.

Digital and Counter Input

Calculated-Channel Configuration

LogBook can derive virtual channels from real and/or virtual channels using math operators and
functions. The resulting virtual channels can be used to:

•

Create alarms based on any combination of signal levels from real channels and logical or
mathematical functions of virtual channels

•

Reduce data through statistical operations, comparisons, etc.

•

Develop sophisticated trigger equations using a series of averaging, comparing of other real and
virtual channels

•

Manipulate input channel values for a more useful output (perhaps the quantity of interest cannot
be measured directly but depends on a complex derivation from several measurements)

•

Control external devices via digital output signals (like a simple Programmable Logic Controller)

Note: Calculated channels can have numeric values such as analog channel values. Calculated channels

can also have digital values of 0 or 1. These channels can be stored in any one (or all 4) timebases
set up in the Acquisition Configuration Window, in the same manner as other input channels.

Bitwise Operators

The bitwise operators perform bitwise-AND (&), bitwise-OR (|), and bitwise-Not (~) operations.

Syntax

AND-expression & equality-expression
OR-expression | Not-expression

Not-expression

The operands of bitwise operators must have integral types, but their types can be different. These
operators perform the usual arithmetic conversions; the type of the result is the type of the operands after
conversion.

&

The bitwise-AND operator compares each bit of its first operand to the corresponding bit of its second

operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result
bit is set to 0.

Example: 10110000

|

The bitwise-OR operator compares each bit of its first operand to the corresponding bit of its second
operand. The operator is inclusive in that, if either bit is 1, the corresponding result bit is set to 1.
Otherwise, the corresponding result bit is set to 0.

Example: 10110000

~

The bitwise-NOT operator creates a bitwise compliment of its operand. Thus, a 0 switches to 1, and a

1 switches to 0.

Example:

~

10110000 = = 01001111

~

AND-expression

&

10010000 = = 10010000

|

10010000 = = 10110000

Bitwise Left Shift and Right Shift Operators:

Syntax:

shift-expression << additive-expression
shift-expression >> additive-expression

The bitwise shift operators shift their first operand left (<<) or right (>>) by the number of positions the
second operand specifies.

Example: 10110000 << 2 = = 11000000

<<, >>

Logical Operators

The logical operators perform logical AND, logical OR, and logical NOT operations.

Logical operators do not perform usual arithmetic conversions. Instead, they evaluate each operand in
terms of its equivalence to 0. Thus, the result of a logical operation is either 0 or 1.

AND

OR

The logical-AND operator produces the value 1 if both operands have nonzero values. If either
operand is equal to 0, the result is 0. If the first operand of a logical-AND operation is equal to 0,
the second operand is not evaluated.

The logical-OR operator performs an inclusive-OR operation on its operands. The result is 0 if both
operands have 0 values. If either operand has a nonzero value, the result is 1. If the first operand of
a logical-OR operation has a nonzero value, the second operand is not evaluated.

The operands of logical-AND and logical-OR expressions are evaluated from left to right. If the
value of the first operand is sufficient to determine the result of the operation, the second operand is
not evaluated. This is called "short-circuit evaluation."

3-34

LogView

9-1-99

,

NOT

The logical-negation (logical-NOT) operator produces the value 0 if its operand is true (nonzero)
and the value 1 if its operand is false (0). The operand must be an integral, floating, or pointer
value.

Examples of Calculated Channels

Example 1: P1_CH00_14 > 23

Look at row 1 in the Calculated Channel Configuration screen (previous figure). You will see that the user
created a calculation function of P1_CH00_14 > 23 for the calculation channel labeled CALC_00. In this
example the user wants to use CALC_00 as a logic indicator based on the state of physical channel
P1_CH00_14; thus channel CALC_00 will read 1 or 0, depending on the value of the physical channel’s
reading. The top screen shows P1_CH00_14 to have a reading of 26.13. Since 26.13 is greater than 23
(from the calculation function), CALC_00’s reading appears as 1.0. If the physical channel’s reading drops
to 23 or lower, CALC_00 will read 0.0. Note that CALC_00 can be used in additional equations, and is
used in the second example.

To obtain a calculation channel, select the Calculated Channel Configuration window’s Edit pull-down
menu, then select Add Channel. In regard to the calculation function column, the following steps highlight
how to enter the function which was used in this first example, P1_CH00_14>23.

1. Ensure the physical channel to be referenced is enabled. For the first example, this was channel
P1_CH00_14.

2. Use the Calc (y = fx) button in the toolbar or Calculated Channels from the View pull-down menu to
access the Calculated Channel Configuration Window.

3. Select the Edit pull-down menu (located on the Calculated Channel Configuration window).

4. Select Add New to add a calculation channel. In our first example this is CALC_00.

5. Click on the cell in the Calculation Function Column. A F(x) button appears by the Enter Function
Expression dialog box.

6. Use the F(x) button to access the Equation Assistance dialog box (illustrated following example 4).

7. In the Equation Assistant box, double-click on the desired reference channel. P1_CH00_14. This
entry will appear in the equation box, located just below the title bar. Note that you may type the
channel, and other equation entries in this box, if desired.

8. From the Relational and Equality buttons, select the “greater than” symbol (>).This entry will appear
in the equation box.

9. With the cursor placed after the greater than symbol, type 23.

10. Verify that your function appears correctly, then select the OK button. This closes the Equation
Assistant.

Though these ten steps pertain to the first example, the method is essentially the same for the remaining
three examples, despite the function differences. A figure and table have been placed after the examples to
identify various button options available with the Equation Assistant.

Example 2: CALC_00 And (P1_CH00_15>24)

Look at row 2 in the Calculated Channel Configuration screen (previous figure). You will see that the user
created a calculation function of CALC_00And(P1_CH00_15 > 24) for the calculation channel having the
channel ID of CALC_01. In this example the user wants to use CALC_01 as a logic indicator based on the
state of both CALC_00 and physical channel P1_CH00_15.

In this example, channel CALC_01 will read 1 if both of the following are true:

a) CALC_00 has a value of 1.0
b) P1_CH00_15 has a value greater than 24

Although the first condition is satisfied, we can see that the second is not, since P1_CH00_15 has a reading
of 21.81. Because both conditions are not satisfied, CALC_01 reads 0.0. Note that CALC_01 can be used
in additional equations.

Example 3: P1_CH01+P1_CH02

Look at row 3 in the Calculated Channel Configuration screen (previous figure). You will see that the user
created a calculation function of P1_CH01+P1_CH02 for the calculation channel having the channel ID of
CALC_02. In this example the user wants to use CALC_02 to indicate to sum of two physical channels,
i.e., P1_CH01 and P1_CH02.

In this example, channel CALC_02 reads 5.393 volts because:

a) P1_CH01 reads 0.398 volts, and
b) P1_CH02 reads 4.995 volts

Note that CALC_02 can be used in additional equations.

Example 4: P1_CH01*2

Look at row 4 in the Calculated Channel Configuration screen (previous figure). You will see that the user
created a simple calculation function of P1_CH01*2 for calculation channel CALC_03. In this example
the user wants CALC_03 to read twice the value of physical channel P1_CH01.

Note that CALC_03 can be used in additional equations.

Acquisition Configuration

The Acquisition Configuration dialog box allows you to define trigger conditions including various
parameters for pre-trigger, trigger, post-trigger, scan rate and timebase.

LogBook data can be collected in two basic ways depending on the trigger setup:

•

Continuous. As a simple data logger in a strip chart mode, all data collected is then saved. The
trigger source can be set to immediate and the post-trigger scan count set to infinite.

•

Exception-only. As an exception-capturing system, collected data is saved only under specified
conditions. Pre-trigger, post-trigger, and re-arm parameters allow you to collect only data around
specified events, just the data of interest, nothing more. Thus memory is conserved, and post-analysis
is easier.

The next figure shows a time line with data being collected continuously, but only the trigger block is
logged to memory (the pre-trigger and post-trigger data combined is called a trigger block).

Trigger Parameters Setup

The next figure shows the basic trigger parameters (channel, condition, threshold, and hysteresis) for an
analog channel as the trigger source (the other sources are also listed).

LogBook can be triggered by several types of sources including analog and digital triggering, multi-step
triggering, multi-channel triggering, time-of-day triggering, and manual trigger. The manual trigger can be
implemented in the following ways:

•

•

The auto re-arm feature allows for a large number of acquisitions to take place automatically, with each
acquisition using the same settings. As soon as the previous trigger block is terminated, the system
immediately re-arms itself, waiting for the trigger condition to be satisfied. The Number of Re-arms field
allows you to specify how many triggered acquisitions to capture. For exception-capturing, specify the
number of trigger blocks that should be collected before data logging is terminated. For continuous data
logging, specify 1 trigger block.

LogBook User’s Manual,

With a PC attached, you can trigger LogBook from LogView’s LogBook Monitor window in the
Device menu.
Without a PC, you can use LogBookK1’s manual trigger button.

LogView

3-37

If Absolute Time is selected for the trigger
source, the window changes as shown in
the figure at right. The parameters include
the date and time as well as options for
retriggering after a specified duration.

A wide variety of trigger sources and stop
events provide great flexibility in
exception-capturing. If data collection is
desired only under specific conditions,
appropriate trigger conditions can be so
specified. Besides the trigger event, you
can define a pre-trigger and post-trigger
for the trigger block. A common example
of exception-capturing would be to collect
100 pre-trigger scans and 1000 post­trigger scans every time a particular
channel measures a certain temperature.

To conserve memory when collecting high-speed data, use the trigger to take snapshots of
information only during the appropriate periods.

When using a trigger to start the acquisition, a pre-trigger count can be supplied so that information just
before the trigger can be collected and saved (LogBook’s buffer allows pre-trigger data to be stored
temporarily until saved in a trigger block). The post-trigger definition specifies when the data collection
activity should end.

3-38

LogView

You can also use a calculated channel as a trigger source, but you must use an analog output or digital
channel as an intermediary. The calculated channel can be based on real channels and user logic to create
an analog output channel or a digital output channel which could then be the input for the trigger event or
stop event. A calculated channel can describe virtually any combination of channel conditions. For
example, you can develop a calculated channel called TRIG and specify it as the trigger channel. If the
channel’s equation is TRIG = (Temp1-Temp2)>50.0°, the data collection process will be triggered when the
difference between the 2 channels is greater than 50.0°.

Scan Rate Setup

The Scan Rate block is the right half of the Acquisition Configuration window (see following figure).
To set the scan rate, you can use LogBook’s “internal” clock, or an “external” clock.

Scan Rate Setup. Accomplished on the right-half of the Acquisition Configuration Window.

•

Internal Clock. The scan-to-scan timing may be set by a fixed-frequency pacer clock. LogBook’s
time-of-day clock has 1/16-second resolution for data-logging applications where acquisitions must be
performed at specific times during the day. The time of occurrence for each acquisition and its trigger
are recorded with the data. The internal clock can be reset in the LogBook Monitor window in the
Device menu.

•

External Clock. Each scan may be individually started by an external trigger to allow the scan rate to
track an external, variable-speed event (such as engine revolutions).

Note: The scan-to-scan time is not recorded when tracking variable-speed events.

For applications with both slow and fast phenomena, sampling slow signals at a slower rate while
maintaining high rates for fast signals will conserve memory. For example, channel 1 may read fast signals
like vibration and can be sampled at the high (base) rate; channel 2 may read slow signals like
thermocouples and can be sampled at a lower rate. A Base Rate A and up to 3 more rates (B, C, D) can be
configured; but only one base rate can be defined for the entire system and it should be set for the fastest
scan required. The B, C, D rates must be integer (whole number) divisions of the base rate. It is also
possible to scan the same channel at several rates.

Note: A separately indexed data file is created for each scan rate.

The checkbox “Apply noise reduction averaging” refers to auto-averaging for scan rates B, C, and D.
All channels are scanned at the base rate; but they may also be scanned at divisions of the base rate. Two
advantages to averaging are noise reduction by limiting the effect of extraneous readings and storage
savings since fewer values are stored.

•

Averaging. Checking this box, the readings from the base rate will be averaged, and the average
value will be entered for the derived rate scan. If the scan rate B is ¼ of the base rate A,
then four A readings will be averaged for each B reading.

•

No averaging. Not checking this box, the readings at the derived scan rates will be exactly the same
for that time-point as the base rate.

Event Marking/Time Stamping

The top right side of the Acquisition Configuration window allows you to manually mark events and/or
insert an absolute time reference for each scan:

•

Enable Event Mark sets up the acquisition for an operator to press the Event Mark button in the

LogBook Monitor window or on the LBK1 remote operation terminal. Whenever the button is
pressed, that data point is added to the data file; when viewing the data file from PostView (discussed
in Appendix F) you can see all the event marks in relation to the corresponding data.

•

Enable Time Stamp sets up the acquisition to automatically add the time (to ms) and date to the data
file for every scan.

Preferences

(no toolbar

LogView allows you to set various
parameters to make your application
more useful and convenient. These
preference settings are divided into 4
tabs as shown in the figures on the
right.

Most of the options cover default use of
filenames and validating changes to
files.

LogView Preferences, General Tab Selected

As explained in the File Management
section (see page 3-7ff), LogView can
generate multiple data files for an
acquisition and then automatically
name them. These names have a long
format with several fields (seed, serial
number, date armed, time armed,
trigger block/segment). Unless you
need the long-format name to prevent
file overwrites, you can uncheck the
fields you don’t need. For example, if
only using one LogBook, the serial
number is not needed.

1) Select the LogView Preferences “General Tab.”

2) Click on the “File Converter” button. The File Converter Preferences dialog box appears.

3) Select the formats you want to save your data in.

4) If desired, check to automatically delete the source data file after conversion. The default avoids
automatic deletion of the source data file.

5) Select the overwriting-related preference you desire. The default is to “Validate overwriting of each
existing file.”

LogView Authorization

(no toolbar icon)

The View Pull-Down menu includes a LogView Authorization dialog box. If you have the Modem Support or
Upload Scheduler feature, you must enter your authorization code to enable the applicable feature. If you do not
have an authorization code you can obtain one from your service representative, or can enable a 30-day trial
period.
