Stub Splices:
The general rule is that there shall
be at least 50mm of twisted wire between any
series of the following connections: splice – splice,
connector - splice, connector - connector, Splices
include wire to wire splices and splice blocks.
Two stubs may be connected to the same stub
connection point at the CAN backbone only on a
125 kb/s (MSCAN) bus. In this case the stubs must
differ in length by at least 10%. Example: If one
stub is 1m long the second can be less than 0.9m
or between 1.1m and 2m.
Stub Topologies:
Stubs connected to stubs are
not allowed. If multiple nodes need to be
connected to a single stub then the nodes must
be series chained. This can be accomplished by
double crimping if only two pins (CAN H & CAN L)
are available or making the CAN Bus connection
through the module if four pins are available (2 x
CAN H & 2 x CAN L).
The maximum number of ECU's on network
transmission speed 125 kb/s, including the
off-board tester, is 32.
The two wires forming each pair of CAN H and CAN
L connections shall be routed via physically
adjacent pins as shown in the figure E212567.
