1.2 General Description
The compact CAN repeater CRep S8C transmits and amplifies
signals transparent to the CAN protocol. Each of the eight CAN
connections has the physical behaviour of a single bus node. CRep
S8C permits a flexible design of the network topology and offers
special support for star structured networks. Furthermore tree
structures and long stub lines are supported. Through the possibility
to use the network structure that fits the application best a reduction
of installation costs can be reached.
The maximum data rate in CAN networks, depending on signal
propagation delays, can be increased, if CRep S8C is used to
improve the network structure. An increase of the maximum node
count in a CAN network can be reached by splitting the network in
subnets that are connected by CRep S8C. Each subnet makes the
number of CAN nodes possible permitted by the drivers output
current. Where CAN signals have to be transmitted over long
distances, CRep S8C can be used for signal conditioning. The
capability to detach erroneous segments from the rest of the CAN
system reduces the impact on the intact bus segments for the most
commonly occuring errors.
The presence of power is indicated by a LED. Furthermore each
CAN channel is provided with a LED indicating that this channel has
originated a CAN message when the LED is on.
