With hardware timestamping, you can log messages with

Overview

microsecond-accurate timestamps for reconstructing network events

and correlating data across synchronized devices. All USB-847x

interfaces use an industry-standard 9-pin male D-Sub (DB9) connector

to interface to CAN and LIN buses.

NI USB-847x devices provide Hi-Speed USB interfaces for Controller Area

Network (CAN) and Local Interconnect Network (LIN) monitoring, logging,

and testing. With high-speed CAN, low-speed/fault-tolerant CAN, and

LIN interfaces featuring optional hardware synchronization, you can use

two or more USB-847x devices together to interface to a wide variety of

CAN and LIN networks.

Hi-Speed USB connectivity and onboard frame buffering ensure

no dropped frames, even under 100 percent bus loads.

The USB-847x interfaces are ideal for many types of

applications, including:

CAN Interfaces

USB-847x CAN interfaces feature the industry-standard Philips SJA1000

CAN controller, which implements ISO 11898 CAN functionality. The

SJA1000 offers additional features to aid in system development,

including listen-only mode, sleep/wakeup mode, error counter access,

and self-reception (echo) mode. USB-847x CAN interfaces recognize

standard (11-bit) and extended (29-bit) arbitration IDs and are compatible

with J1939 networks.

• In-vehicle network monitoring and logging

• Bus load monitoring

• Device validation with synchronized data acquisition

• CAN device development and test

• CAN and LIN data correlation with external measurements

The convenient all-in-one design features a captive 2 m USB cable

and built-in transceiver, requiring no extra cables or accessories to

get applications running quickly.

CAN and LIN Interfaces for Hi-Speed USB

features baud rates up to 20 kb/s and offers advanced power

management with a low-power sleep mode.

Hardware Synchronization

No Connection

Optional Ground (V –)

Many automotive applications demand tight integration of CAN, LIN,

analog, and digital measurements. In applications such as CAN device

development and validation, you need to synchronize different measurements

to correlate data. You can program this synchronization in software, but

OS latency and clock drift between the different onboard oscillators

introduce unacceptable delays for certain automotive test applications.

NI offers USB-847x CAN and LIN interfaces with an optional hardware

synchronization feature, with which the USB interfaces can share timing

and triggering signals with other USB-847x interfaces, as well as data

acquisition, vision, and motion devices, to achieve true hardware

synchronization. Determinism is maintained between the trigger signal

and the desired response because timing and triggering signals are

handled in hardware. The host PC software interacts only to retrieve the

data once it is acquired or to write new data.

National Instruments provides NI-CAN driver software for Windows

Vista/XP/2000. NI-CAN includes a detailed API and examples for

NI LabVIEW and LabWindows/CVI, Microsoft Visual C/C++ 6.0 and

Visual Basic 6.0, and Borland C/C++. USB-847x interfaces use the NI-CAN

Frame API for frame-level access to messages on CAN and LIN networks.

The NI-CAN driver software also includes the Bus Monitor and NI Spy

utilities to aid in application development.

Figure 2. LIN DB9 Connector (USB LIN Modules)

Low-speed/fault-tolerant USB-847x CAN interfaces offer software-

selectable termination for compatibility with all low-speed

network configurations.

NI-CAN Frame API

The NI-CAN Frame API offers a powerful interface for accessing NI CAN

hardware. The API enables full access to all traffic on CAN and LIN buses.

It is a powerful tool for implementing a variety of applications, including

CAN and LIN frame-level access, challenge response protocols, remote

frame handling, and advanced synchronization.

Onboard Physical Layer

The CAN physical layer connects the CAN controller to the physical

bus wires. USB-847x CAN interfaces are available with high-speed and

low-speed/fault-tolerant physical layers. All USB-847x devices have

onboard physical layer transceivers and require no external dongles.

The physical layers are internally powered via a DC-to-DC converter

and electrically isolated up to 500 V.

Bus Monitor

To quickly monitor all CAN and LIN bus traffic, use Bus Monitor, a

utility that offers an easy-to-use interface that displays all CAN and

LIN frames on the network, and log the traffic to disk. Bus Monitor

provides options to control, display, and view bus statistics.

LIN Interfaces

NI USB-8476 LIN interfaces, featuring the Atmel ATA6620 LIN

transceiver, are compliant with the LIN 1.3/2.0 and J2602 specifications

and offer software-selectable master/slave termination. The ATA6620
