Wiring
A CAN BUS network should never have a star topology . Rather, the correct topology is a line from the
first device (with terminator) to the second, third and so forth. The last bus device has the termina -
tion jumper again.
Example : Connection of three network nodes (NWN) with a 2x2-pole cable and termination of the ter -
minal network nodes (network inside one building)
Each CAN network is to be provided with a 120 ohm BUS terminator at the first and last network sub -
scriber (= termination ). This is achieved with a plug-in jumper at the back of the controller . Each CAN
network therefore always has two terminators (one at each end). Branch cables or a star topology
are not permissible for CAN wiring.
