Compact Data Logger Acquires OBD & CAN Bus Data

The stand-alone logger supports all of the leading automotive protocols including CAN (Controller Area Network) to acquire OBD and Enhanced Diagnostic data. In addition, it supports the J1939 heavy duty protocol. The DAWN Mini Logger works well for a wide range of applications including fleet monitoring, R&D, duty cycle measurements, and service. The user has the option to connect a PC to the Mini Logger for real-time data analysis and display. Computer interface options include USB, Bluetooth and a cellular modem.

DAWN (Data Acquisition With Networks) has a Windows user-interface that allows the user to easily configure the logger without any programming using flowcharts, tables and dialogs. The same DAWN software acquires and displays real-time data on a PC and configures the stand-alone logger with the parameters to acquire. The software also displays the data as a post process.

By acquiring Enhanced Diagnostic data, DAWN can acquire a few hundred parameters from multiple controllers simultaneously. Using a special test mode, data is acquired up to a rate of 250 samples/sec for each parameter. This overcomes the limitations of most acquisition tools that can only acquire from one controller at a time. It also overcomes the typical OBD limitation of only acquiring data at 20 samples/sec aggregate. Thus, 5 simultaneous parameters could only be acquired at 4 samples/sec each for a competitive system.

The Mini Logger automatically starts and stops acquiring data when the vehicle ignition is turned on and off. It has a low power mode when shutdown and a 1 year warranty. Also included are a Cabin Temperature Sensor and a 3-axis MEMS accelerometer. Options include a cellular modem and an 8 channel A/D. Storage media is up to 2 GB on a mini SD card. Its operating temperatures range from -40 to 70C and operating voltages range from 6 to 40V.

The DAWN software works with any J2534 compatible device. J2534 is the SAE standard that defines the Application Program Interface (driver API) between the PC and OBD test tool. This means that the DAWN software works with any test tool that conforms to the J2534 specification.

The introductory list price for the DAWN Mini Logger is $1,495.00 for one unit, and there are discounts for volume orders.

HEM Data

HEM Data Corporation was founded in 1986 to develop software for data acquisition and analysis. HEM Data's products include DAWN (Data Acquisition With Networks), Snap-Master (data acquisition with real-time & post analysis), and NOVA (Noise and Vibration Analyzer). Applications include: testing in vehicles, laboratory, field, and factory settings. HEM Data offers complete hardware and software solutions that work with a PC and as a stand-alone logger / flight recorder.

HEM Data Corp. conducts a seminar for the Society of Automotive Engineers (SAE) entitled "Acquiring & Analyzing Data from Sensors and In-Vehicle Networks." This seminar covers the traditional way to acquire data directly from sensors and the newer alternative to acquire data directly from the in-vehicle network, which could have hundreds of parameters available without adding any sensors. If you want this seminar conducted at your location or tailored to your applications, please contact HEM Data at support@hemdata.com, or call (800 436-4330). Tutorials for acquiring in-vehicle network data using CAN and other protocols are covered in HEM Data's eNewsletters. To receive these eNewsletters click here.
