Depending on the number of networked controllers a smaller value may be necessary
for the pull-down resistor.
If the CAN wiring is not laid in a straight line it may be necessary to individually opti-
mise the amount and location of the terminating resistors. For instance in a star net-
work a central 60 Ohm terminating resistor may be more suitable. When the optimum
arrangement of terminating resistors is fitted, no accumulation of error frames should
be evident.
