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

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. 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. 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


CarDAQ-Plus HTA Heavy Truck Adapter  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 includes standard Deutsche 6-pin and 9-pin cables. Using the standard CarDAQ-Plus driver, you create programs to reprogram ECU's, log data, or monitor bus traffic. We're recommending these extensions for standardization in SAE J2534-2. In addition, the Drew Technologies RP1210A DLL can be used to work with existing RP1210 applications
Compact Flash CArd Compact Flash memory may be added to the CarDAQ-Plus when ordering. When CF memory is added, the CarDAQ-Plus can utilize that memory within Linux for hosting applications or storing data. This option is most useful for developers that are writing custom applications for CarDAQ-Plus. When ordered with a CarDAQ-Plus, the memory will be installed in the internal CF slot for CarDAQ-Plus unless otherwise specified. Standard sizes are 256MB, 512MB, 1GB, 2GB, 4GB, and 8GB cards. For those cards not listed on the online ordering form, please call to get pricing and availability.
