I don't know if there's a written standard. I've never done any CAN other than install a system on a boat. The "backbone" was only 20cm long consisting of 5 Tee connectors branching off to peripherals, and two terminators. The data rate was 250kb/s (NMEA-2000). The way i did that installation was as detailed in the instructions for the equipment. I know everything down to the protocol level about how CAN works and have thought of using it in some products. If the data rate is high and there's a lot of peripherals connected to one point, the combined capacitance or transmission line reflection effects of cables going to the peripherals could make the data at the central point of connection a bit noisy. Keeping the cable lengths to the peripherals short would help. Apart from that, i'd be confident it would work if i did it myself. -- regards, Russell Shaw, B.Eng, M.Eng(Research) -- Archives and useful links: http://groups.yahoo.com/group/CANbus Subscribe and unsubscribe at www.vector.com/canlist/ Report any problems to <[email protected]>
