Since the CAN interfaces of all EVI Audio appliances are galvanically separated from the rest of the circuitry, network cabling also carries a common ground conductor (CAN_GND) ensuring that all CAN- interfaces in the network are connected to a common ground potential.

By using a CAN bus repeater a connection between two independent and
•Increase of the max. number of members
A maximum of 100 devices can be connected to one CAN bus. This number can be increased up to 250 by connecting several CAN bus systems. This limitation of exactly 250 devices results from the addressing scheme used by the CAN bus. The addressing scheme allows the allocation of a maximum of 250 different CAN device addresses.
•Improvement of signal quality
With CAN bus systems, whose bus length exceeds 1000 meters, a CAN bus repeater should be used. The CAN bus repeater accomplishes a signal processing and a reinforcement of the bus signals. The internal running time of the repeaters of approx. 150 ns corresponds to an extension of the bus over approx. 45 meters.

By using one or several repeaters, not only the
