Abstract
A controller area network (CAN) has a plurality of nodes connected to transmit and receive data over a serial data line using an interface circuit to connect the node to the data line. Each interface circuit includes an isolation element, typically a diode, to connect the interface circuit to the data line. An indicator element in the interface circuit is powered when the node is transmitting. The isolation element in each node prevents other nodes while transmitting, from powering the indicator element in its node.
