2.6. Terminal Resistor Setup

In order to minimize the reflection effects on the CAN bus line, the CAN bus line has

to be terminated at both ends by two terminal resistors as in the following figure.

According to the ISO 11898-2 spec, each terminal resistor is 120Ω (or between

108Ω~132Ω). The bus topology and the positions of these terminal resistors are shown

as following figure.

Each I-2533CS-FD includes one build-in 120Ω terminal resistor, users can decider

to enabl it or not. The DIP switch for terminal resistor is on the upper of the CAN

connector.
