Introduction 2

The DBK70 is an electronic module that can be quickly configured to generate analog output signals that
are proportional to many typical vehicle characteristics based on a single connection to the vehicle’s
diagnostic connector. The DBK70 provides sensor module signals of vehicle characteristics from data
acquired from a vehicle’s data bus (e.g., J1850, J1850 VPW, J1850 PWM, Class 2, SCP, CAN, etc.).

Once configured using the included software, the DBK70 will capture the selected vehicle network
message and convert the imbedded data into a proportional analog output suitable for measurement with
any IOtech data acquisition product or equivalent.

Monitoring the messages transmitted on the network eliminate the need to outfit the vehicle under test with
transducers and wiring that would be redundant with the vehicle’s existing transducers and wiring. Where
the data rate available from a vehicle’s data bus is satisfactory, the DBK70 can create output waveforms
comparable to direct transducer measurement.

Depending on availability through the data bus, the DBK70 is also able to generate signals proportional to
data internal to a vehicle’s electronic modules, which is typically inaccessible for monitoring or recording.
Through the vehicle data bus, the DBK70 can obtain such data from any vehicle module accessible through
the same vehicle data bus that is used for vehicle diagnostics.

Through the DBK70, vehicle data contained in normally occurring messages used for the operation of the
vehicle and/or available through diagnostic protocols can be monitored and used to generate scaled, analog
output. Every DBK70 analog output channel is independently configured. Each data received and
processed has two independent sets of scaling parameters, one to control the output signal and the other to
format the data for real time display on a PC.

DBK70 User’s Manual 946898 Introduction 2-1

Since the DBK70 contains a non-volatile memory that holds all of its setup parameters, the PC need only
be connected to initially configure the DBK70 or to make configuration changes. During normal operation,
no PC connection is required. In addition to configuring the DBK70, the included software also allows the
operator to view parameters on-screen in real-time. The DBK70 configuration and monitoring software
runs on any PC that is using Windows 95, 98, Me, 2000, or NT.

The DBK70’s operation is completely configurable through the use of supplied software and a
configuration database. Through this software and database a user can quickly change the configuration of
any and all output channels, monitor in real time the operation of each output channel, and/or create or edit
members of the configuration database.

The DBK70 can be operated as an accessory to IOtech’s DaqBook, DaqBoard, LogBook, or WaveBook
product lines, or as a stand-alone device providing analog outputs for any voltage measurement instrument
including hand-held meters and strip chart recorders.

Software Installation

DBK70 Software and Database Requirements

The DBK70 software and database runs under Windows 98, Me, 2000 or XP.

DBK70 Software and Database Installation

A CD ROM is distributed with the DBK70. This CD ROM contains a copy of the DBK70 software and a
copy of a starter DBK70 Database (i.e., DBK70.mdb).

To install the DBK70 software and the DBK70 Database, use the following procedure.

Run Setup.exe

Place the DBK70 CD ROM in your CD ROM drive. If the Windows Auto Detect option is set, the SETUP
program will start automatically. If not, select “Run” from the Windows “Start” menu. Browse, if
necessary, and run the “Setup.exe” program.

Carefully follow the screen prompts to install your software.

Powering the System Using Auxiliary Power or Vehicle Bus Power

The DBK70 receives its access to the vehicle’s data bus and power through a connection to the vehicle’s
diagnostic connector. The CA-210 cable is used to connect the DBK70 to the vehicle’s standard
Diagnostic Connector (i.e., SAE J1962). The other end of this cable is connected to the DBK70. Typically,
the power pins on the vehicle’s diagnostic connector are only active when the vehicle is on.

The Vehicle Diagnostic cable must be connected to the DBK70 first and the vehicle’s
diagnostic connector second.

The Auxiliary Power input is primarily used to operate the DBK70 when not connected to a vehicle. In
some instances, it may be preferable to configure the DBK70 outside of the vehicle, in an office or lab
setting. Use the included AC power adapter in these circumstances. When not connected to a vehicle
network, real-time message values cannot be monitored in the software.

DBK70 User’s Manual 927994 System Setup 3-1

Configuring a DBK70

The DBK70 generates analog output signals that are proportional to vehicle data the DBK70 acquires from
a vehicle’s data bus.

The DBK70 uses a connection to the vehicle’s diagnostic connector to obtain access to the vehicle’s data
bus and to obtain the power it needs to operate and to create the output signals. A serial connection to a PC
is used when configuring the DBK70’s output channels and/or to monitor the vehicle data being processed
by the DBK70.

Once its output channels are configured, the
operation of the DBK70 is automatic.
Whenever the DBK70 is connected to vehicle
power, it loads the configuration information
last saved in its non-volatile memory, and
begins processing data and generating output
signals. As the DBK70 receives data from the
data bus, it creates scaled analog output signals
based on the received data. Whenever the
data associated with an output channel is
unavailable, a channel specific default
output signal value is generated.

To configure the DBK70, connect it to your PC’s serial port and launch the included software application.
The software provides database management and channel configuration services.

Using a DBK70 in Stand-Alone Mode

Use the PC’s serial port to configure the DBK70

The DBK70 can be used with any voltage measurement instrument in a stand-alone mode. After
configuring the DBK70 with the included software, connect it to the vehicle’s diagnostic connector. When
the DBK70 receives power from the vehicle, it will immediately begin monitoring the network and
updating its analog outputs to reflect the values of the desired messages, as per its saved configuration.

Attach your voltage measurement device to the DBK70’s analog outputs through the analog output
connectors.

Reference Note:

Refer to page 4-3 for more information.

The DBK70 provides single-ended analog outputs, where all outputs are referenced to the same internal
analog ground. Follow the recommended guidelines below to get the best quality readings from your
measurement equipment.

Isolated Measurements

When used with a measurement
device having isolated inputs, connect
any of the DBK70’s ground pins to
each of the low-side inputs of the
measurement device. Attach each of
the DBK70 analog outputs to the high­side inputs of the measurement device.
It is not necessary to tie the ground of
the DBK70 to the ground of the
measurement device.

3-2 System Setup 927994 DBK70 User’s Manual

Differential Measurements

When a differential input
measurement device is used, the
analog ground of the measurement
device must be connected to the
analog ground of the DBK70. This
ground cannot be greater than 30
volts above the vehicle’s chassis
ground.

Single-Ended Measurements

When measuring the DBK70
outputs with a single-ended
device, the analog grounds from
the DBK70 and the measurement
device must be tied together.

DBK70 User’s Manual 927994 System Setup 3-3

Using a DBK70 with a WaveBook

The DBK70 has both straight-through and multiplexed outputs. The multiplexed outputs are designed
specifically for use with IOtech’s Daq* and LogBook products. The straight-through outputs can be used
with any measurement device, including IOtech’s WaveBook products.

Reference Note:

Refer to the block diagram on page 2-1 to better understand the relationship between the
multiplexed and straight through outputs.

3-4 System Setup 927994 DBK70 User’s Manual

To use the DBK70 with a WaveBook, connect the DBK70’s analog outputs to unused WaveBook voltage
inputs using the optional CA-208 cable. A single CA-208 supports 8 channels; thus two CA-208 cables are
required to connect all 16 DBK70 analog outputs to a WaveBook and/or to any WaveBook expansion
modules.

In WaveView, the data acquisition software included with the WaveBook, use the mx+b (scale and offset)
feature to convert the DBK70 voltage values into engineering units. For example, if the DBK70 is
capturing vehicle RPM in the range of 0 to 5000 RPM and scaling the result to 0 to 5 volts, setting the “m”
in WaveView to 1000 will convert the incoming voltage to RPM. This technique can be used in any data
collection software package to convert the DBK70’s output voltage to engineering units.

Reference Note:
mx + b values are included in a Microsoft Excel file: mx+b values.xls. The file is

located in the root directory of your DBK Configuration CD (p/n 1056-0600).

DBK70 User’s Manual 927994 System Setup 3-5

Using a DBK70 with a Daq* Product or LogBook

The DBK70 has both straight-through and multiplexed outputs. The multiplexed outputs are designed
specifically for use with IOtech’s Daq* and LogBook products. The straight-through outputs can be used
with any measurement device, including IOtech’s WaveBook products.

Reference Note:

Refer to the block diagram on page 2-1 to better understand the relationship between the
multiplexed and straight through outputs.

To use the DBK70 with a DaqBook, DaqBoard, Daq PC-Card, or LogBook, connect the DBK70’s P1
connector to the P1 connector of any of the aforementioned data acquisition products via a ribbon cable
(CA-37).

From the perspective of, for example, the DaqBook, the DBK70 represents an analog input expansion
module that is multiplexing 16 analog inputs into one of the DaqBook’s analog input channels. The
example diagram below shows the JP1 jumper in the DBK70 set to channel 1. When the sequencer selects
base channel 1 and expansion channel 15, the voltage signal passes through the highlighted path.

3-6 System Setup 927994 DBK70 User’s Manual

• The Daq* sequencer selects the channel and gain by controlling multiplexers (MUX) and

programmable gain amplifiers (PGA) in both the Daq* and the DBK. The sequencer uses 4 expansion
address lines to provide 16 unique channel addresses for each base channel.

• The DBK70 multiplexer selects 1 of 16 (max) channels as directed by the sequencer. The selected

signal goes to the channel-selection jumper, and then to the Daq* via P1.

• The Daq* multiplexer selects 1 of 16 base channels from P1 input lines as directed by the sequencer.

The selected signal goes to the PGA and then to the A/D converter (A/D).

• The P1 interface has a signal line for each of the 16 base channels.

• The JP1 channel select jumper in the DBK70 can be placed on pins for channel 0 through channel 15.

Each DBK70 in the system must occupy a different base unit channel. The factory default setting for the

JP1 jumper is channel 0.

Reference Note:

Refer to the DaqView or LogView documentation for instructions on how to inform the
software of the presence of DBK modules and cards.

Using the steps described in the DaqView or LogView documentation, the user must provide the location
of the JP1 jumper to the software.

In DaqView or LogView, use the mx+b (scale and offset) feature to convert the DBK70 voltage values into
engineering units. For example, if the DBK70 is capturing vehicle RPM in the range of 0 to 5000 RPM and
scaling the result to 0 to 5 volts, setting the “m” in WaveView to 1000 will convert the incoming voltage to
RPM. This technique can be used in any data collection software package to convert the DBK70’s output
voltage to engineering units.

Reference Note:
mx + b values are included in a Microsoft Excel file: mx+b values.xls. The file is

located in the root directory of your DBK Configuration CD (p/n 1056-0600).

Auxiliary Power Connectors

Either port can be used to supply auxiliary power
to the DBK70. When attached to a vehicle
network, the vehicle will supply adequate power
for the DBK70, so no additional power need be
connected via the Auxiliary Power Connector. To
power the DBK70 in the lab or office, disengaged
from the vehicle network, use the included
external AC supply. The 2
connector is used to cascade externally supplied
power to another piece of data acquisition equipment.

Power Issues

There are 2 methods for powering a DBK70; applying DC power to either of its Auxiliary Power inputs or
through the vehicle network. When connected to a running vehicle, the vehicle power received from the
diagnostic connector is all that is necessary to power the DBK70 – no further power connections are
necessary.

In rare instances where power is not available on the diagnostic connector, the DBK70 can be powered
from its Auxiliary Power connector using a cigarette lighter power cord (IOtech p/n CA-198)

The Auxiliary Power input is primarily used to operate the DBK70 when not connected to a vehicle. In
some instances, it may be preferable to configure the DBK70 outside of the vehicle, in an office or lab
setting. Use the included AC power adapter in these circumstances.

nd

Auxiliary power

LED Operation

Three LEDs on the front panel of the DBK70 provide feedback as to
the current state of the unit. When sufficient power supply voltage is
supplied, the Power LED will blink. When both power is applied and
network activity is sensed, the Power LED will remain solid. If the
DBK70 is powered but not connected to the vehicle network, no
activity will be sensed, therefore the Power LED will blink.

• When connected to the network of a running vehicle and the analog outputs are configured, if the

Power LED is not solidly illuminating, it is likely that the vehicle bus is malfunctioning or the
DBK70 network interface is not operating correctly. This could be due to having the incorrect
network interface installed in the DBK70.

• The Transmit LED will flash when the DBK70 is issuing a request message onto the network. If the

Update Rate field is set to 0 and/or the Message field is blank for all desired messages, the DBK70
will never issue messages onto the network, therefore the LED will never blink.

• The Receive LED will flash whenever any desired messages have been detected. A desired message

is defined as a message that the DBK70 has been configured to capture. If the Receive LED never
flashes, the desired bus messages, defined in the fields of the database, are not being detected. This
could be due to an incorrect message definition in the database, or that the desired message needs to
be requested before it is transmitted.

Vehicle Diagnostic Connectors

The J1962 Vehicle Diagnostic Connector is required on all new automobiles sold in the USA after model
year 1995. It may also be available on a few model year ‘94 and ‘95 vehicles sold in the USA. Tentatively,
it will also be required on all new automobiles sold in the EC in calendar year 2000 and later.

Different vehicle manufacturers may give different names to the vehicle’s diagnostic connector. Some may
call it the ALDL connector, the Class 2 connector, the SCP connector, the 16-Way, the J1850 connector, or
the diagnostic connector.

The vehicle’s diagnostic connector is typically mounted under the instrument panel on the driver’s side of
the vehicle. The connector is typically mounted in or near a center console or under the instrument panel on
the driver’s side of the vehicle.

Serial Port Cable, CA-212 RS-232 [Included]

For the purpose of configuring the analog outputs, the DBK70 is connected to the PC via the included

CA-212 RS-232 cable. The CA-212 is a “straight through” serial cable – pins 1 through 9 on one end are
connected to pins 1 through 9 on the other end, respectively.

Vehicle Network Cable, CA-210 [Included]

The CA-210, included with the DBK70 provides a connection between the vehicle’s diagnostic connector
(OBD) and the DBK70, regardless of the type of interface supported by your vehicle. The connector is
typically located under the dashboard near the steering column.

Chassis Label

The DBK70 has eight internal slots into which configuration cards can be installed. Four slots are reserved
for Network Interface cards, and four slots are for Parameter Capture cards. If only one network is to be
used (such as J1850-VPW), then only one Network Interface card is required. If multiple networks are to be
attached to one DBK70, then up to four Network Interface cards can be installed.

Network interface
module slots

Parameter capture
module slots

Each Parameter Capture card supplies 4 analog outputs, enabling the simultaneous capture of up to four
parameters, such as four different temperatures within the vehicle. To capture more than four parameters
simultaneously, additional Parameter Capture cards can be installed. Up to four cards, for a total of 16
network parameters, can be simultaneously captured by one DBK70.

Each DBK70 is configured with plug-in cards. A label located on the bottom of the DBK70 identifies the
cards installed at the factory. A colored in circle denotes the presence of the associated analog output card
or network interface card. Each analog output card (parameter capture card, DBK70-P4) has
four analog outputs. For example, if 3 cards are installed 12 parameters can be captured.

Card Installation

Network Interface Cards

The vehicle network card(s) are inserted into the 4 header sockets located adjacent to the network
connector of the DBK70, on the LED-side of the product. Network cards must be inserted into the proper
socket, as shown in the call-outs on the diagram below.

Analog Output Cards

The Analog Output Cards (DBK70-P4) are inserted into the 4 sockets adjacent to the analog output
connectors on the DBK70. Populate the sockets starting with the right-most socket continuing left until the
desired number of cards have been installed. Make sure no card has any open sockets to its right. The cards
must be oriented as shown in the diagram below.

When the DBK70 powers-up, the DBK70-P4s are immediately recognized and initialized. Each DBK70-P4
carries its own calibration constants on an on-board memory device so cards can be inserted in the field
without the necessity of re-calibration.
