Overview
The CarDAQ-Plus is the ultimate interface for
communicating with newer automobiles, heavy duty trucks,
and CAN networks. It has both Ethernet and USB
connectivity to a PC, a built-in operating system for
running internal programs, protocol support for all
modern vehicles, and six analog inputs. No other J2534
tool on the market has the performance and capabilities
of the CarDAQ-Plus. It is upgradeable thru firmware
updates and expansion slots. The
CarDAQ family is the most talked-about J2534 interface
out there.

J2534-1 Reflashing Applications for Independent Repair Shops
Servicing newer, more increasingly complicated
vehicles has put independent repair shops at a disadvantage against
auto dealerships that have access to the latest service tools and
knowledge databases. Accurately diagnosing and repairing many of
these newer vehicles used to require full access to expensive factory
service tools. The EPA recognized the independent repair shop’s
need for access and mandated that all OEMs comply with the SAE standard
J2534-1. The SAE J2534-1 standard defines a uniform hardware device,
like the Drew Technologies CarDAQ-Plus, that all automakers must support
with their vehicle reflashing applications.
Having access to SAE J2534-1 software
and tools are important for several reasons. First, diagnosing and
repairing vehicles often requires reprogramming or reflashing the
vehicle with the latest update. After a vehicle is assembled and
sold at a new car dealership, the automaker’s engineering groups
often fix common problems found at the dealership by releasing a
new reflash. The reflash is not a recall, and therefore most vehicles
on the road will not get the update unless they are brought in to
the dealership for servicing. These reflashes could fix transmission
shifting problems, hesitation, rough idle, drivability, check engine
lights, emissions quality, poor performance, or any of a number
of other problems. Without the reflashing capabilities, independent
repair shops may spend time and money trying to repair an issue
with hard parts that cannot be repaired without a calibration flash
update.
The Second reason a repair shop should have
a SAE J2534-1 device is to offer their customers flash updates as
an up sell. Even if the customer does not believe they are experiencing
a problem with their vehicle, they may see some benefit in performance,
drivability, or even fuel economy by getting their vehicle updated
to the latest available calibration flash. It also serves as good
preventative maintenance to update the calibration flash and avoid
any problems that it was intended to fix.
J2534-2 Support
The EPA standard for independent shop reprogramming is
J2534-1, but since automakers recognized that the J2534-1
standard did not cover all of their needs for the future. This
lead to the development of J2534-2, a set of optional
extensions. The CarDAQ-Plus from Drew Technologies supports many
J2534-2 extensions. Drew Technologies is also working with the
SAE and automakers to establish a SAE J2534-3 standard for
compliance. This support protects your investment.
Supported J2534-2 extensions include:
- Single Wire CAN
- CAN Mixed Mode
- A/D Inputs
- Pin Switching

| Article - Why Drew Tech and CarDAQ-Plus are the
right choice. Thru the years, many people have
asked us what makes J2534 tools different. While it is
true that J2534 is a written standard, many companies in
the industry have offered products that do not fully
implement the standard.
Drew Technologies not only implements the standard
fully, but also rigorously tests it's products with each
and every automaker that offers J2534 software. This
article explains that there is a difference in which
tool you choose.

OEM and Development Features
CarDAQ-Plus has many uses beyond the independent
repair shop. The CarDAQ-Plus was designed to be a high
performance development tool. It performs the standard PassThru J2534 functionality, adds an
internal 200MHz embedded Linux host, an internal and
optional external Compact Flash
slot, and an internal web server for thin-client
applications. In addition to acting as a
laptop-to-vehicle PassThru device, it can also host
diagnostic and data logging applications on-board.
Compact Flash expansion for Wireless
802.11, GPS, and more
The CarDAQ-Plus has one internal and one
optional external Compact Flash slot that can be used simultaneously.
The external Compact Flash slot is optional and must be ordered
at the time of purchase. For wireless connectivity, we interface
802.11 WiFi compact flash cards. This is
the same proven technology found in most modern laptops.
It provides the speed, range, and reliability needed for
wireless applications. The Compact
Flash expansion slots may also be used for other CF peripherals,
such as GPS receivers, expanded storage, modems, and any other
CF card that supports Linux. The CarDAQ-Plus will support up to
8GB of memory per Compact Flash slot
Remote Diagnostics and Standalone
operations
CarDAQ-Plus runs it's own operating
system, embedded Linux, which allows it to be used as a
standalone tool without a PC attached during operation. The
Linux installation includes a file and web server which could
simplify development of remote diagnostics and management
applications. Imagine writing your own C/C++ application
to perform an on-road test, then use 802.11 WiFi to
wirelessly download a vehicle's data as soon as it
re-enters the repair facility. Your program could access
GPS compact flash card to capture location information
about the test-drive, or use a cellular modem and
download telemetry from live tests! For standalone applications, this provides the features
of a PC host and a PassThru device all in one package.
Tools available for development
Drew Technologies provides an
application programmer interface (DLL) for OEMs,
integrators, or end-users to develop their own PassThru
(SAE J2534) applications. You can use any PassThru
(J2534) compliant application with the CarDAQ-Plus. You
can also Create
your own applications in LabVIEW™, C or Visual Basic. Use your favorite language, including: TCL, Perl, .Net,
Java, or C.

Optional Accessories
|
|
OBD2 vehicle communications and
In-vehicle networks require the use of
the CDP-J1962 cable. The CDP-J1962 cable is a cable that has the MVCI 26
pin connector on one end and the 16-pin J1962 connector
on the other end. This cable is required when connecting
a CarDAQ-Plus to the OBD2 / Diagnostics port on any 1996
or newer compliant automobile. |
 |
Diagnostics, Data Logging, and
Analysis is possible with PCMSCAN. PCMSCAN is a fully featured OBD-II scanner and
diagnostic tool. It allows viewing, charting, logging
and playback of diagnostic data in real time via the
vehicle's OBD-II diagnostic data port. It also allows
viewing of vehicle Diagnostic Trouble Codes (DTC's),
Freeze Frame data, and other vehicle information.
Supported OBD-II protocols: SAE-J1850 (PWM and VPW),
ISO-9141, ISO-14230 (KWP2000), and ISO-15765 (CAN). |
 |
Wireless Access
to the CarDAQ-Plus can be supported with the optional
802.11 Wireless upgrade. The 802.11 upgrade
includes an 802.11b wireless adapter that is installed
in the external Compact Flash slot of the CarDAQ-Plus.
With this upgrade, you can connect a CarDAQ-Plus to
wireless networks or newer computers with
factory-equipped 802.11 wireless adapters. The wireless
option will allow wireless access between the PC and
CarDAQ. |
 |
Heavy Duty J1939 Trucks
can use the CarDAQ as an interface with the MVCI-to-heavy
duty truck adapter.The MVCI-to-heavy-truck adapter allows CarDAQ-Plus to communicate on
J1939 and J1708 networks. It supports most standard Deutsche 6-pin and
9-pin cables. Using the standard CarDAQ-Plus driver, you create programs
to reprogram ECUs, log data, or monitor bus traffic. We're recommending
these extensions for standardization in SAE J2534-2. In
addition, the Drew Technoloiges
RP1210A DLL can be
used to work with existing RP1210 applications |
|
Temperature Signal
Conditioning can be done thru TempDAQ. TempDAQ is a rugged temperature-compensated amplifier that supports up
to 6 input channels. It rescales the voltage signal from K-type
thermocouples to use the full dynamic range of CarDAQ's A/D subsystem.
This permits highly accurate in-vehicle temperature measurements:
between -200C and +1250C, with better than 1C resolution. Alternatively,
select the BNC input to pass a signal (unamplified) directly to CarDAQ.
The A/D subsystem can sample up to 6 voltage signals with range 0-27V,
at 2kHz, with 12-bit resolution. The user can set each channel
separately for temperature or "raw" voltage measurement.
