2.6. Terminator 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 terminator resistors as in the following figure.
According to the ISO 11898-2 spec, each terminator resistor is 120Ω (or between
108Ω~132Ω). The bus topology and the positions of these terminator resistors are
shown as following figure.
Each I-2533CS series includes one build-in 120Ω terminator resistor, users can
decide if it is enabled or not. The DIP switch for terminator resistor is under the power
connector.
