4.3.5. CAN (CAN-Bus)
The device is equipped with a 2-wire serial remote control interface
carrying the CAN-Bus signals to enable remote control with the
d&b R60 USB to CAN or R70 Ethernet to CAN interfaces.
Note: A detailed description of remote control via the d&b
Remote network (CAN-Bus) is given in the technical
information TI 312 (d&b code D5312.EN) which can be
downloaded from the d&b website at www.dbaudio.com .
All pins of both connectors are wired in parallel allowing either to
be used as input or output (daisy chaining) or for terminating the
CAN-Bus network.
Pin assignment
The pin assignments of both, the RJ 45 sockets and the cable
connectors, are shown in the graphic opposite.
Note: The connections for the CAN-Bus are referenced to
common ground. The "CAN Ground" is routed via the
cable shielding and is hardwired to PE.
Within the CAN-Bus network, shielded cables and shielded
RJ 45 connectors (metal housing) must be used while the
cable shielding must be connected to both sides.
