DBK70

Vehicle Network InterfaceFeatures• Measure up to 70* vehicle network
parameters with one DBK70• Synchronously record vehicle network
data along with analog and digital
measurements made with IOtech’s
data acquisition systems• Supports J1850 VPW, J1850 PWM,ISO-9141, CAN, J1939, Keyword2000• Up to four network types can be­attached concurrently to one DBK70• Attaches to any of IOtech’s data­acquisition products• DBK70 can also be used with any dataacquisition device in a stand-alonemode
The DBK70 vehicle network module ­allows
IOtech’s data acquisition products to record
vehicle network parameters synchronouslywith measurements made by IOtech dataacquisition systems. In contrast to othervehicle network recording systems, theDBK70 offers a unique solution that guarantees time correlation between vehicle
network parameters and direct analog anddigital measurements.
By attaching the DBK70 to the vehicle’s
OBD (on-board diagnostic) connector,­network parameters of all kinds can be­recorded along with measurements fromtransducers attached directly to IOtech’s
family of data acquisition products.
For example, when-combined withIOtech’s WaveBook portable data acquisition device, up to 72 transducer or­network channels can be read at up to1 Msample/s. When attached to aDaqBoard/2000 PCI card, up to 407 channels of analog, digital, counter/timer, andvehicle network channels can be collected
at up to 200 kHz. For stand-alone applications, the DBK70 can be used with IOtech’s
LogBook to collect hundreds of channels oftransducer data and network parameters atup to 100 kHz without the need for a PC.
IOtech’s solutions offer better performance
than ­others costing s­ ignificantly more.

The DBK70 can easily be integrated with any of IOtech’s data acquisition products
An advantage of IOtech’s unique system isthe ability to display scrolling waveformsof vehicle parameters and transducer channels concurrently in real time. The DBK70’s
unique architecture facilitates synchronization by converting vehicle network­messages into analog values that are thendigitized by the data acquisition system. In
this way, the data acquisition ­system canmeasure vehicle network parameters alongwith other transducer signals, synchronousto one another.
The DBK70 was designed specifically fordata collection tasks, so there’s no needto learn complicated in-vehicle network­analysis software. The DBK70 includes asoftware application that provides ­databasemanagement and setup services. Unlike
other network devices, no costly software
add-ons are required.

c­ onfiguration into the DBK70’s ­nonvolatilememory via its serial ­configuration port.
The DBK70 has four internal slots into whichparameter-capture cards (DBK70-P4) canbe installed. Each capture card adds fourvehicle parameters that can be monitored,
for a total of 16 parameters for each DBK70(see PidPRO software for monitoring up to70 channels).
One DBK70 can be connected to up tofour different networks concurrently. The
DBK70’s multiple network ­interface allows
the flexibility to use one device on multiple vehicle platforms, or to concurrently
collect data from ­multiple networks on asingle vehicle. Internal interface slots allow
up to four network ­modules to be ­inserted.

As part of vehicle network protocol, allmessages transmitted on the network carrya parameter identifier (PID). To set up theDBK70, you can enter proprietary PIDsdirectly into the software application orimport an existing PID database. The software is delivered with a database of morethan 600 PIDs. After the PIDs are entered,simply select the messages of interest, set
the desired sample rates, and download theThe CA-210 network cable provides the DBK70
with vehicle bus data

Example Applications
Brake Performance Testing

While a DaqBook data acquisition ­system directly measures thermocouples, strain gages,and accelerometers, the DBK70 can provide
important vehicle network parameters suchas speed and RPM. Using the DBK70 tomonitor vehicle parameters eliminates theneed to connect redundant transducers andmeasurement equipment.

system collects data into its internal PC-Cardmemory without requiring an attached PC.
Using the LogBook’s accelerometer signal
conditioning module, ­vibration and shock
can be measured while synchronously
capturing speed and RPM from the vehicle­network using the DBK70. The LogBook/360
can also synchronously collect location
information from any GPS receiver, allowing vibration data to be correlated to trackposition. In addition, acquired data canbe accessed remotely via a cellular ­modem
attached to the LogBook.

DBK70General Information
Portable Data Acquisition Products

Out-of-the-Box software, included with most IOtech ­products,
combines an easy-to-use interface with a powerful set of features that include hardware setup, trigger definition, real-time
indicators like scroll charts and bar graphs, sample rate setup,
direct-to-disk acquisition, and data format conversion for popularanalysis packages like DIAdem®, DASYLab®, DADiSP™, MATLAB®,
and ­Excel®. Also included is PostView, an extensible, full-featured
post-acquisition waveform ­display and ­inspection package.

IOtech’s data acquisition products, to which the DBK70 attaches,
are capable of collecting data from a wide variety of inputs including low and high voltages, currents, thermocouples, RTDs,
accelerometers, strain gages, bridge devices, pulse train sources,and digital signals.

PidPRO Software
Included with each DBK70 is PidPRO, a software application for
setting up the DBK70, managing PID databases, and ­viewing network data. For additional functionality, the PidPRO Plus software
add-on provides data logging, automatic DBK70 setup features,a network monitor, and the ability to configure up to 70 datachannels through a feature called virtual channels.
In addition to capturing the 16 specified parameters associatedwith its analog outputs, the DBK70 is also capable of capturing
parameters associated with up to 70 virtual output channels. Oncethe DBK70 outputs are configured, data from both the physical andvirtual outputs are continuously streamed out the DBK70’s RS-232port. After the configuration is saved in the DBK70’s non-volatilememory, the unit will power-up configured and begin sending theserial ASCII data stream. Virtual outputs provide an economicalmeans of increasing the number of vehicle ­network parameters
monitored. Documentation and examples are ­provided to captureindividual channel data in DASYLab using its RS-232 function
module, and LogView using the LogBook/GPS software option.

Assign a PID record to a DBK70 channel in just three steps

The Network Monitor feature included with the PidPRO Plus software add-on provides a means of viewing in real-time ­unmodified
network traffic in a scrolling text window. In the monitoring
window, the user can provide filtering and interactively transmit
network messages while watching network messages scroll by in
the text window. The monitor allows the user to passively probe
the network for messages or interact as desired.
For quick configuration of all of the DBK70’s output channels,
PidPRO Plus includes a Load From File feature, which allows theuser to save/load an entire DBK70 output channel configuration
to/from disk. This time saving feature ­eliminates the need toconfigure each channel, one at a time.
