low-speed/fault-tolerant usb-847x can interfaces offer software- selectable termination for compatibility with all low-speed network configurations. 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 onboar d physical layer transceivers and r equir e no exter nal dongles. the physical layers are internally powered via a dc-to-dc converter and electrically isolated up to 500 v. 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 features baud rates up to 20 kb/s and offers advanced power management with a low-power sleep mode. hardware synchronization 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 desir ed r esponse because timing and triggering signals ar e handled in hardware. the host pc software interacts only to retrieve the data once it is acquired or to write new data. ni-can software national instruments provides ni-can driver software for windows v ista/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. 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 power ful tool for implementing a variety of applications, including can and lin frame-level access, challenge response protocols, remote frame handling, and advanced synchronization. bus monitor t o quickly monitor all can and lin bus traf fic, use bus monitor , a utility that of fers an easy-to-use inter face 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. can and lin interfaces for hi-speed usb 2 buy online at ni.com or call 800 813 3693 (u.s.) figur e 2. lin db9 connector (usb lin modules) figure 1. can db9 connector (usb can modules) 1 2 3 4 5 6 7 8 9 n o connection no connection ground no connection g round lin no connection vbat shield 1 2 3 4 5 6 7 8 9 no connection can_l v C n o connection optional ground (v C c an_h n o connection v+ s hield
