Abstract
A data transmission system for external use with a controller area network is installed on a motor vehicle undergoing high intensity electromagnetic interference susceptibility testing. The data transmission system includes a fiber optic cable extending from the immediate vicinity of the truck to a site relatively remote to the truck and out of the effective area of the artificially generated electromagnetic interference. An optical/electrical coupler in close proximity to the motor vehicle is connected to the vehicle controller area network to convert messages occurring on the network to optical signals. The connection is provided by an electrical cable constructed of a twisted pair of wires. The optical/electrical coupler is also connected to an end of the fiber optic cable in the vicinity of the truck. A remote data processing device is attached to the remote end of the fiber optic cable by an interface card installed in the remote data processing device. The interface card converts optical signals to controller area network compatible electrical signals for evaluation.
