TempBook/66 Block Diagram

The TempBook/66 adds voltage and thermocouple measurement capability to notebook PCs for portable
test applications. The TempBook also provides an effective alternative to plug-in boards for desktop PCs.
The TempBook provides 12-bit, 100 kHz data acquisition and can support up to 800 Kbyte/s data transfer
to a PC via an enhanced parallel port interface or PCMCIA link. The unit can also connect to a standard
parallel port and transfer readings [directly to disk] at up to 100K readings/s. As an external module with
the same footprint as a typical notebook PC, the TempBook can be attached directly under a notebook PC
for portability.

The TempBook has a built-in analog capability that permits it to measure 8 channels in a differential mode
or 16 channels in single-ended mode. Its on-board programmable-gain instrumentation amplifier can be set
to gains of ×1, 2, 5, 10, 20, 50, 100 or 200 on a per channel basis. Its A/D converter scans selected
channels at a constant 10 us/channel rate, minimizing the time skew between consecutive channels. The
time between the start of each scan sequence can be programmed to start immediately or at intervals of up
to 10 hours. The TempBook features a hardware-based digital/TTL trigger that minimizes trigger latency to
less than 10 us. The TempBook can also be triggered from a command from the PC.

The TempBook/66 can be powered by an included AC adapter, a standard 12V car battery, any
+9 to 20 VDC source, or an optional rechargeable nickel-cadmium battery module (DBK30A). This makes
it ideal for field and remote data acquisition applications.

Introduction and Quick Start 1-3

Quick Start

For those users who wish to get their TempBook up and running as quickly as possible, this section
provides a brief explanation of the steps required.

Signal Connection

The thermocouple and voltage input signals are fed to the TempBook through a removable termination
card. To remove this card, rotate the ejector handle with your thumb or finger. Once removed, the
thermocouple or voltage connections should be made as shown in the figure.

Reference Note: Refer to chapter 2, Installation and Configuration, if you are not
already familiar with TempBook systems, or if you need information that goes beyond
the scope of this Quick Start.

The DIP switches located on the termination card connect optional biasing resistors as well as input filters.

For further details, refer to section Termination Card and I/O Connectors in chapter 2.

PC Connection

The TempBook communicates with a laptop or desktop computer through the parallel printer port. Connect
the supplied cable to the computer’s parallel port and the TempBook's parallel port.

Signal Connections, Differential and Single-Ended

When connecting both low and high level signals, the low-level signals should be
connected to the lowest numbered channels with connections following in ascending
order of signal magnitude.

•

For thermocouple or other differential inputs, these switches should be closed to provide the required
bias current path.

•

For single-ended inputs these switches can be optionally opened or closed.

1-4 Introduction and Quick Start

PC-to-TempBook Connection

04-26-01_o

TempBook User’s Manual

Power Connection

The TempBook is typically powered from the supplied wall-mount converter or from an optional DBK30A
battery module. The wall-mount converter plugs into any standard 110 VAC wall outlet and its other end
plugs into the circular DIN5 receptacle on the TempBook's rear panel. If using the battery module, please
refer to the section Rechargeable Battery Module in chapter 2.

Software Installation

The TempBook/66 comes with a Microsoft Windows-based application (32-bit DaqView) that provides the

TempBook User’s Manual

04-26-01_o

Introduction and Quick Start 1-5

Reference Note:

Users of 32-bit TempBook Support should refer to the DaqView, DaqViewXL, and
PostView document modules.

Users of 16-bit TempBook Support should refer to the TempView and PostView
document modules.

Parallel Port Capabilities

The TempBook includes a test program that verifies your computer's parallel port, testing its standard and
enhanced capabilities.

•

Standard LPT ports on IBM compatible computers have two modes to read data from the printer port:
4-bit and 8-bit. The 8-bit mode is somewhat faster than the 4-bit, but not all printer ports support this
mode.

• Enhanced parallel ports (EPP) are parallel ports that include additional hardware that allows the

TempBook to communicate with the PC at 3 to 10 times the speed possible with standard parallel
ports. This greatly improves data acquisition performance.

Enhanced parallel ports require special hardware, and only certain computers are EPP capable. Most laptop
computers that use the Intel 386SL or 486SL chip set (which includes the 82360 I/O Controller) are EPP
capable. For those computers which have plug-in card slots, EPP adapter cards are available. You may
wish to contact your computer's manufacturer for details about your machine and possible adapter cards.

TempBook Configuration Under Windows 95/98/ME/NT/ and 2000

This section describes the configuration of TempBook devices under the Windows 95/98/ME/NT and 2000
operating systems. A configuration utility is supplied via a control panel applet. The Daq Configuration
applet allows you to add a device, remove a device, or change existing configuration settings. Daq
Configuration also has a built-in test utility to test the device. The test utility provides feedback on the
validity of the current configuration settings as well as providing relevant performance summaries.

Daq Configuration can be found in the Windows
control panels and can be executed any time that it is
desirable to add, remove or change device
configuration settings. Daq Configuration may also
be entered during driver installation. The following
description applies to either method.

The Daq Configuration/Device Inventory screen at
right will display all currently configured devices.
Devices are identified by their name, and by an icon
that indicates the device type. If no device is currently
configured, no device will appear in this field.

The 4 buttons across the bottom of the Daq
Configuration screen are used as follows:

• Properties. Current configuration settings for a

device can be changed by bringing up the
corresponding properties screen. To do so,
double-click the device icon or single-click the
device and then select the Properties button.

Introduction and Quick Start 1-7

Resource Tests

The resource tests are intended to test system capability for the current device configuration. These tests
are pass/fail. Resource test failure may indicate a lack of availability of the resource or a possible resource
conflict.

• Base Address Test - This test will test the base address for the selected parallel port. Failure of this

test may indicate that the parallel port is not properly configured within the system. See relevant
operating system and computer manufacturer’s documentation to correct the problem.

Performance Tests

The performance tests are intended to test various
TempBook functions with the current device
configuration. These tests give quantitative results for
each supported functional group. The results represent
maximum rates at which the various operations can be
performed. These rates depend on the selected parallel
port protocol and will vary according to port hardware
capabilities.

• ADC FIFO Input Speed - This test will test the

maximum rate at which data can be transferred from
the TempBook’s internal ADC FIFO to computer
memory through the parallel port. Results are given
in samples/second (sample is 2 bytes in length
representing a single A/D count).

Inspection

The TempBook components were carefully inspected prior to shipment. When you receive your data
acquisition system, carefully unpack all items from the shipping carton and check for any obvious signs of
physical damage that may have occurred during shipment. Immediately report any damage to the shipping
agent. Retain all shipping materials in case you must return the unit to the factory.

Every TempBook is shipped with the following items:

•

TempBook Data Acquisition System

•

User's Manual

• Installation CD

• Calibration Constants Disk

• Accessory Kit, including: CA-35-2 (2 ft parallel port cable) and an AC Adapter

Panel Connectors and Indicators

The TempBook front panel consists of 3 status-indicator LEDs. The rear panel consists of the power
switch, power input, two DB25s for parallel port connection and pass-thru, and a slot to accept the input
termination card. The function of each of these components is described below.

Termination Card and I/O Connectors

The TempBook/66 accepts all analog and digital I/O signals via a removable termination card (see figure).
This termination card has six screw terminal strips, a CJC temperature sensor, and input R/C filters which
also provide a bias current return path for the TempBook's instrumentation amplifier. The filters/bias
resistors are switch-selectable on a per channel basis.

TempBook Termination Card

Terminal strips J2 and J3 provide analog input signal connection. Note that the terminals are arranged in
differential pairs for easy thermocouple connection. These terminal strips also provide analog signal
common connections for convenient referencing of single-ended input signals.

Terminal strips J4 and J5 provide connections for the eight digital outputs and the TTL trigger input. These
terminal strips also provide ground connections for referencing digital signals. Terminal strips J6 and J7
provide connections for the eight digital inputs, the pacer clock output (OUT2), and the three counter/timer
(8254 P0) I/O signals.

2-2 Installation, Configuration, and Calibration

04-25-01

TempBook User’s Manual

The thermocouple or voltage connections should be made as shown in the following figure.

Analog Signal Connection

When connecting both low and high level signals, the low-level signals should be
connected to the lowest numbered channels with connections following in ascending
order of signal magnitude.

Each of the 16 analog input channels is configured as shown in the
figure (also, refer to page 2-10 for more information on wiring
differential inputs).

The series resistance and shunt capacitance form a single-pole low­pass filter with a corner frequency of 15.9 kHz. The shunt
resistance provides the bias current path for the instrumentation
amplifier.

When reading thermocouples, these filters should be switched in.
If the filters are not used with thermocouples or any other
differential input, then the user must provide a bias current return
path to signal common.

Two DIP switches need to be set for each differential channel.

Internal Configuration

Reference Note:
This section pertains to TempBook/66 hardware configuration. Software installation and
software configuration under Windows 95/98/Me/NT and 2000 is discussed in chapter 1.

To open the unit, place the TempBook on a flat surface.
Remove the screw on the top rear of the case, and slide out the
top cover. Reverse this procedure to assemble the unit.

The internal configuration of a TempBook/66 consists of
setting the following jumpers to reflect the desired mode of
operation:

•

Time Base (JP9)

• Watchdog Timer Enable (JP8)

The location of each jumper is shown in the figure.

TempBook User’s Manual

04-25-01

Installation, Configuration, and Calibration 2-3

Watchdog Timer Enable/Disable (JP8)

This 3-pin header allows the elective use of the TempBook watchdog timer
function. If using a printer with the TempBook, the watchdog timer should
be enabled to allow the TempBook to be most reliably reset by the host
computer. Note that enabling the watchdog timer might impede background
measurements. If the user is not going to attach a printer, the timer is
optional. The default setting is Watchdog Timer Disabled. To enable, place
the shunt jumper in the enabled position as shown in the figure. To disable,
place the jumper in the disabled position, as shown.

Time Base Selection (JP9)

This 2×2 header allows the user to select one of two oscillator derived
frequencies to be applied to the pacer clock (8254 P1 & P2). The pacer clock
sets the interval between scans in continuous trigger mode. The two
frequencies are 1 MHz and 100 kHz. The most useful range of clock output
frequencies [for the typical user] is provided by the default, 1 MHz setting.

DaqView only supports a setting of 1 MHz, which is the factory default.

Hardware Installation

Connect the TempBook to any PC parallel printer port (female DB25) by unplugging the printer cable and
plugging the male end of the supplied cable (CA-35) into the computer and the female end into the mating
connector on the TempBook. Any printer port (LPT1, LPT2, or LPT3) may be used but should be noted
for use in software installation.

TempBook allows for LPT pass-through for simultaneous data acquisition and printer operation. When
using a printer in the system, attach the original printer cable male DB25 into the mating connector on the
TempBook.

The TempBook may be powered by the supplied AC adapter that plugs into any standard wall outlet or
from an isolated 9-20 VDC source of 1-2 A.

If using the power adapter, plug it into a 120 VAC outlet, and attach the low voltage end to the jack on the
TempBook. Turn ON the power switch, and the POWER LED should be on.

At power-on, the printer should behave normally and can be checked by issuing a PRINT SCREEN
command (or any other convenient method of checking the printer). (Installation of the software will be
necessary before the TempBook can perform any functions.)

Rechargeable Battery Module (DBK30A)

For portable applications where external AC or DC power is not available, the DBK30A rechargeable
nickel cadmium battery module can be used with the TempBook/66. This module is housed in a rugged
metal package that is the same size as the TempBook. It also comes with high-strength Velcro tabs that
allow convenient mounting underneath the TempBook/66.

The DBK30A has two modes, the 14 VDC default and the 28 VDC mode. An internal slide-switch
determines the mode.

Only the 14VDC mode of the DBK30A is to be used with the TempBook/66.

The 14VDC operating mode provides 14.4 VDC at 3.4 A-Hr. This setup can power the TempBook for 3 to
6 hours depending on the application. The battery module has built-in automatic battery-charging circuits,
which quickly and safely recharge the internal batteries when connected to the supplied AC adapters. The
only requirement for trouble-free operation is for the user to fully charge the battery module before
attempting to use it.

2-4 Installation, Configuration, and Calibration

TempBook User’s Manual

Charging the Battery Modules

The DBK30A package includes a charger for the intended line voltage (either 120 VAC or 230 VAC). To
charge the battery module, plug the output cable from the charger into the POWER IN connector on the
DBK30A, and plug the charger into an appropriate source of AC power (see figure). The charge cycle will
be initiated automatically, and the batteries will be fully charged after the charging cycle terminates.

To initiate another charge cycle, depress the START CHARGE momentary rocker-arm switch. Subsequent
charge cycles applied to a fully charged DBK30A will have no ill effect because the DBK30A will sense
the fully-charged status of the batteries and revert to the trickle-charge state within a few minutes.

Three LED status indicators on the DBK30A provide information on the charge process or external load as
noted in the table.

from the battery modules.

Battery Module Connection

The DBK30A package includes a short connecting cable (CA-115) to connect to the TempBook. This
cable connects the Power Out connector on the DBK30A to the Power In connector on the TempBook (see
figure).

The run time available from a DBK30A operating a TempBook will depend on what the TempBook is
doing. This time can be as little as 3 hours or as much as 6 hours.

The DBK30A must periodically be fully discharged or the cells may develop "lazy
chemistry" that may limit storage capacity. (This “memory” is characteristic for
nickel-cadmium batteries.) To manually discharge a battery pack, connect a
TempBook, and leave it turned on until the indicator lights go dark.

Connection Troubleshooting

If communications cannot be established with the TempBook or if trying to connect causes the system to
hang or crash, then you should:

• Check that TempBook’s power LED is ON. If not ON, verify power connection between the

TempBook and the power source.

• Make sure the LPT cable is firmly attached to the computer’s proper LPT port and to the TempBook

port labeled “TO COMPUTER”.

•

Check that the desired LPT port has the proper resource configurations. The base address and IRQ
level must be properly configured and recognized by the operating system. The parallel port must be
capable of generating interrupts for proper operation. (This information may be obtained in the
Device Manager in the Control Panel of the operating system). More information on this subject can
be found in the readme.txt file in the current software release.

•

Check the BIOS settings for the LPT port. If ECP, change to normal or bi-directional.

• Make sure the BIOS LPT protocol settings are compatible with the settings selected for the LPT port

with the Control Panel applet.

• Make sure the Daq Configuration Applet has been run and the proper LPT port and protocol have

been selected for the device. The Daq Configuration applet can be found in the Control Panel of the
operating system. The Test Hardware function in the control panel applet can be used to confirm
proper communication with the device.

2-6 Installation, Configuration, and Calibration

04-25-01

TempBook User’s Manual

Calibration of TempBook

The TempBook/66 is factory calibrated for gain and offset. After calibration, gain and offset errors, and
software correction constants are calculated.

Calibration Constants File Installation

Each TempBook is shipped with a calibration constants file. The file is named serial_no.cal where
serial_no is the serial number of the TempBook for which the constants were generated.

The default calibration constants filename is tempbook.cal. Use Windows Explorer to copy serial_no.cal
from the disk to the following directory.

C:\PROGRAM FILES\DAQX\APPLICATIONS\TEMPBOOK.CAL\

Within DaqView, the user must go to Window/P
TEMPBOOK.CAL file.

Next one should enable “Perform zero-offset adjustment” by checking the check box.

Hardware Calibration

Since the TempBook is factory calibrated, user recalibration is not recommended. One exception to this
recommendation is the calibration of the TempBook's internal 5V reference. This 5V reference is used to
level-shift the amplified analog input signal for unipolar measurements. Reference-voltage drift is not
compensated for with zero compensation; and therefore, periodic recalibration can improve unipolar
measurement accuracy.

The following characteristics can be calibrated through potentiometer adjustments on the TempBook main
board:

• 5V Reference Voltage

•

Instrumentation Amplifier Offset

• Level Shift Amplifier Offset

• ADC Offset

• ADC Span

The TempBook includes a simple calibration program that can be used to perform these adjustments. If the
user is only performing the reference voltage adjustment, then only a 4-1/2 digit DMM is required. If the
user is performing the full TempBook calibration, then an adjustable voltage calibrator is also required.

Reference Note:

Refer to the DaqView document module for more information.

A Microsoft Windows program, DAQCAL.EXE, is provided to perform calibration of the TempBook. To

Differential Measurement Configurations

Floating Differential

Floating differential measurements are generally made when low-level signals must be measured in the
presence of relatively high levels of common mode noise. The most common example would be a non­grounded thermocouple. When the signal source has no direct connection to the system analog common,
one must be provided. The easiest way to do this on the TempBook is to use the built-in biasing resistors
by closing the corresponding input channel DIP switches (S1 and S2) on the termination card. Discussion
of the card begins on page 2-2. As an alternative, a resistor can be connected between one of the two signal
lines (usually the lower in potential) and common. A resistor of 10 KΩ to 100 KΩ is satisfactory (less
noise with the lower values).

Floating Differential Configuration

Referenced Differential

Referenced differential measurement is used when measuring several voltages. However, the voltages
cannot share the same common node as a group of single-ended measurements might. An example is to
measure several currents via shunts that happen to share a common supply terminal along a bus. The
weakness in a single-ended hookup is that current flow through the common bus can introduce substantial
errors that can be indistinguishable from the real values measured. The need for the system common to be
connected to the common supply terminal is shown in the figure.

Overview

DaqView is a 32-bit Windows-based data acquisition program that can be used to operate DaqBoard/2000
Series boards, ISA-type DaqBoards, DaqBooks, Daq PC-Cards, and TempBooks.

Daq devices typically make use of optional DBK cards and modules. TempBooks are never used with
DBK cards or modules.

Note: TempBook does not make use of optional DBK cards or DBK modules.

DaqView was designed for ease-of-use; programming expertise is not required. DaqView allows you to:

•

Set up system parameters (selecting channels, gains, transducer types, etc) to acquire data.

• Save data to disk and transmit data to spreadsheets and databases.

•

Automatically re-arm the trigger function and save data in new files as needed.

•

Configure and operate the DBK option modules. Does not apply to TempBook.

• Configure the counter/timer into one of three modes for measuring frequency, totalizing, or

generating pulse trains. Does not apply to TempBook.

• Use the two analog outputs, including waveform generation for DaqBoards.

Does not apply to TempBook.

• Use digital I/O (for Daq devicess with digital I/O). Does not apply to TempBook.

PostView can be launched from DaqView to view, measure, and edit data. PostView is discussed in

a separate document module that is included as part of this manual.

DaqViewXL is a Microsoft Excel-based “add-in.” The application is discussed in a separate document

module that is included as part of this manual.

Starting DaqView

Minimum computer requirements include:

• Intel

• 32 Mbytes of RAM

• Windows 95/98, Windows NT 3.51, or Windows NT 4.0

•

Data acquisition hardware

To run DaqView, double-click the DaqView icon or use your Windows desktop Start button to navigate to
the program file.
Note: If acquisition hardware is not available, or you just want to explore the software, you can select
Simulated Instrument; the main window will open (see following figure).
When DaqView detects hardware, or a simulated instrument has been selected, DaqView’s main window
will open.

Note: In event of a Daq device communication problem, exit DaqView and perform a hardware test from

the Daq Configuration applet control panel.

The following figure shows DaqView’s main window for a DaqBoard/2000 and a TempBook. The table

Functionality Differences amongst the DaqBoard/2000 Series Boards

Each of the DaqBoard/2000 Series Boards has a different I/O count. DaqBoard/2001 has more I/O than
any of the other boards [in the 2000 series]. All other 2000 series boards are essentially derivations of
DaqBoard/2001.

The differences in the boards are paralleled in the DaqView software. Basically, if a board does not support
a particular function, the related software feature will be disabled (grayed-out). When using any of the
information presented in this chapter, always take time to note whether or not it applies to your specific
