5 Connection of the CAN-bus repeater
(article no. 486 R000)
The active CAN repeater is a module to enlarge the CAN-bus topology. A repeater provides eight galvanic
disconnected bus segments.
Each of this bus segments can connect up to five modules on a max. length of 1000 m. The individual bus
segments are to be provided as necessary with a separate power supply.
The connection is carried out by circuit board connectors. The transfer rate is adjusted by the factory to a
value between 5 kBit/s and 50 kBit/s.
In case of long cable lengths or security applications the use of an active CAN repeater is inadvisable.
The figure below shows which connections of the CAN-bus inside the CAN repeater have to be terminated.
The figure can only be seen as an example.
